                               PROSPECTUS SUMMARY

    The following summary is qualified in its entirety by reference to the more
detailed information and financial statements, including the notes thereto,
appearing elsewhere in this Prospectus. Except as otherwise indicated, all
information in this Prospectus, including per share data and information
relating to the number of shares outstanding, (i) has been adjusted to reflect a
1-for-1.61083 reverse stock split of the Common Stock effected on July 20, 1998,
(ii) gives effect to the conversion of the outstanding shares of Series B
Convertible Preferred Stock into 310,399 shares of Common Stock upon the
consummation of this offering, and the issuance of an aggregate of 48,125 shares
of Common Stock upon the consummation of this offering in connection with the
acquisition of CommHome Systems Corp. (the "CommHome Acquisition") and
satisfaction of certain indebtedness of CommHome, and (iii) assumes no exercise
of the Underwriter's over-allotment option to purchase up to 281,250 additional
shares of Common Stock. See "Business -- CommHome System Corp. Acquisition,"
"Certain Transactions" and Note J to Notes to Financial Statements.

    Certain statements contained herein under "Prospectus Summary," "Risk
Factors," "Use of Proceeds," "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Business" including, without
limitation, statements concerning the Company's strategy and growth plans,
contain certain forward-looking statements concerning the Company's operations,
economic performance and financial condition. Because such statements involve
risks and uncertainties, actual results may differ materially from those
expressed or implied by such forward looking statements. Factors that could
cause such differences include, but are not limited to, those discussed under
"Risk Factors."

                                   The Company

    Network-1 Security Solutions, Inc. (the "Company") develops, markets,
licenses and supports a family of network security software products designed to
provide comprehensive security to computer networks, including Internet based
systems and internal networks and computing resources. The Company's
FireWall/Plus family of security software products enables an organization to
protect its computer networks from internal and external attacks and to secure
organizational communications over such internal networks and the Internet. The
Company also offers its customers a full range of consulting services in network
security and network design and support in order to build, maintain and enhance
customer relationships and increase the demand for its software products.

    The FireWall/Plus family of security solutions is designed to protect
against Internet and intranet (internal networks utilizing Internet technology
and applications based upon TCP/IP - the Internet network transport protocol)
based security threats and to address security needs that arise from within
internal networks that often utilize other network transport protocols besides
TCP/IP including, among others, Novell's IPX, Digital Equipment's DECnet and
IBM's SNA. The Company's FireWall/Plus family of firewall products operates on
the Microsoft Windows NT operating system platform. FireWall/Plus's proprietary
Interceptor Shim and filter engine software technology, with its unique ability
to handle and filter all commonly used network transport protocols, provides
organizations with a highly secure and flexible security solution. Additionally,
unlike most other firewall solutions which focus on an enterprise's connection
to the Internet, the FireWall/Plus solution can be deployed throughout the
enterprise; at the perimeter to control access 




                                       3



to and from the Internet, between internal networks and on application servers
and desktop PCs to protect data residing on such servers and PCs. FireWall/Plus
for Windows NT received the 1997 Internet and Electronic Commerce Conference
award for "Best Intranet Solution" and the 1997 ENT Readers Choice Award for
"Best NT Firewall."

    As a result of the explosive growth in network computing and Internet use
(as well as use of intranets and extranets), protection of an organization's
network and data has become a significant economic concern for businesses.
According to the 1997 Annual Information Week/Ernst & Young LLP Information
Security Survey of information technology managers and professionals, 42% of the
respondents reported malicious acts from external sources, as compared to 16% in
the prior year, and 43% of the respondents reported malicious acts by employees
as compared to 29% in the prior year. According to FBI estimates, U.S. companies
suffer estimated losses of $5 to $10 billion per year as a result of
unauthorized access to information and data. According to the 1998 Computer
Security Institute/FBI Computer Crime and Security Survey, 44% of the
respondents reported unauthorized access by employees. The Company believes that
securely segmenting internal network areas and computing resources from
unauthorized access will become paramount to insuring the integrity of both the
internal network and an organization's intranet and extranet (intranets which
allow access for one or more users outside of the internal network) resources.

    In a Windows NT based environment, it is typical for multiple network
transport protocols to co-exist, as Windows NT comes pre-equipped with TCP/IP,
IPX (Novell), NetBEUI (LAN Manager) and AppleTalk. In addition, certain
applications require the use of non-TCP/IP protocols to operate between
subnetworks within a network. The Company believes that multiple network
transport protocols will remain prevalent in computing environments because of
the large installed base of non-TCP/IP based computer systems and applications.
As a result, the Company believes that its FireWall/Plus technology offers
significant advantages as a security product for computer networks because of
its unique ability to filter all commonly used network transport protocols and
reside in multiple locations throughout an organization's network.

    The Company intends to pursue an aggressive growth strategy and to focus its
efforts on marketing its FireWall/Plus family of network security products. Key
elements of the Company's strategy are to:

    -    Provide comprehensive network security solutions by developing,
         marketing and supporting a family of network security products to
         address a broad range of security issues confronting computer networks
         and computing, including concerns arising from allowing access to the
         Internet as well as concerns relating to the security of internal
         networks.

    -    Emphasize internal network security because of the ability of
         FireWall/Plus to filter a multitude of network transport protocols
         which are common in many organizations. The Company intends to devote a
         significant portion of the proceeds of this offering for sales and
         marketing toward educating potential end users and third-party
         distributors as to the need to protect networks and computing resources
         from unauthorized access and attacks from within an internal network
         and the capabilities and benefits of the Company's products.



                                       4



    -    Implement a marketing plan which includes a multi-channel distribution
         strategy which emphasizes establishing and maintaining third-party
         distributor relationships with systems integrators, VARs, OEMs and
         resellers in the United States and internationally.

    -    Increase sales of FireWall/Plus by leveraging relationships with
         consulting clients.

    Since its inception, the Company has incurred significant losses. The future
success of the Company is largely dependent upon its FireWall/Plus family of
software products achieving market acceptance. There can be no assurance that
the Company will be able to successfully implement its marketing strategy,
achieve significant market acceptance of its FireWall/Plus products or achieve
profitable operations.

                                  RISK FACTORS

    An investment in the shares of Common Stock offered hereby is speculative
and involves a high degree of risk and should not be purchased by anyone who
cannot afford the loss of their entire investment. Each prospective investor
should carefully consider the following risk factors as well as the other
information set forth in this Prospectus in evaluating an investment in the
shares of Common Stock offered hereby. This Prospectus contains forward-looking
statements based upon current expectations that involve risks and uncertainties.
The Company's actual results and the timing of certain events may differ
materially from those discussed in such forward-looking statements as a result
of certain factors, including, but not limited to, those set forth in the
following risk factors and elsewhere in this Prospectus.

    Limited Relevant Operating History; Significant and Continuing Losses;
Explanatory Paragraph in Independent Public Accountant's Report. Although the
Company was organized in July 1990, it was engaged primarily in providing
network consulting and training services through 1994 and did not commence
marketing of its first FireWall/Plus product until June 1995. Accordingly, the
Company has a limited relevant operating history as a software developer upon
which an evaluation of its prospects and future performance can be made. Such
prospects must be considered in light of the risks, expenses and difficulties
frequently encountered in the operation and expansion of a new business and the
shift from research and product development to commercialization of products
based on rapidly changing technologies in a highly specialized and emerging
market. Since inception, the Company has incurred significant net losses,
including net losses of $4,499,000, $2,390,000 and $697,000 for the years ended
December 31, 1996, December 31, 1997 and the three months ended March 31, 1998,
respectively. At March 31, 1998, the Company had an accumulated deficit of
$8,167,000 and since March 31, 1998 the Company has continued to incur
significant losses. The Company will also incur aggregate non-cash charges
during the three months ended June 30, 1998 and upon consummation of this
offering of approximately $1,335,000 relating to (i) the amortization of debt
discount with respect to $3,250,000 principal amount promissory notes which will
be repaid in full, together with accrued interest thereon, upon consummation of
this offering and (ii) purchased research and development in connection with the
CommHome Acquisition. In addition, the Company will incur non-cash charges of
$900,000 over a four-year period related to stock options issued in May 1998 to
Avi A. Fogel, President and Chief Executive Officer of the Company. Inasmuch as
the Company intends to increase its level of activities following the
consummation of this offering and will be required to make significant up-front
capital expenditures in connection with its sales and marketing and continuing
research and product development efforts, the Company anticipates that losses
will continue until such time, if ever, as the Company is able to attain sales
levels sufficient to support its operations. There can be no assurance that the
Company will ever achieve profitable operations. The Company's independent
auditors have included an explanatory paragraph in their report on the Company's
financial statements for the years ended December 31, 1996 and December 31, 
1997, stating that certain factors raise substantial doubt about the Company's
ability to continue as a going concern. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations," "Certain
Transactions" and Financial Statements.

    Significant Capital Requirements; Working Capital Deficit; Dependence on
Proceeds for Plan of Operation; Continuing Need for Additional Financing. The
Company's capital requirements have been and will continue to be significant,
and its cash requirements have been exceeding its cash flow from operations. At
March 31, 1998, the Company had a working capital deficit of $2,283,000. As 



                                       7



a result, the Company has been substantially dependent on private sales of
equity and debt securities to fund its operations. The Company is dependent on
the proceeds of this offering to implement its business plan and finance its
working capital requirements. The Company anticipates, based on currently
proposed plans and assumptions relating to the implementation of its business
plan (including the timetable of, costs and expenses associated with, and
success of, its marketing efforts), that the net proceeds of this offering,
together with projected revenues from operations, will be sufficient to satisfy
the Company's operations and capital requirements for approximately twelve
months following the consummation of this offering. There can be no assurance,
however, that such funds will not be expended prior thereto due to unanticipated
changes in economic conditions or other unforeseen circumstances. In the event
the Company's plans change or its assumptions change or prove to be inaccurate
(due to unanticipated expenses, difficulties, delays or otherwise) or the net
proceeds of this offering and projected revenues otherwise prove to be
insufficient to fund the implementation of the Company's business plan or
working capital requirements, the Company could be required to seek additional
financing sooner than currently anticipated. The Company has no current
arrangements with respect to any additional financing. Consequently, there can
be no assurance that any additional financing will be available to the Company
when needed, on commercially reasonable terms or at all. Any inability to obtain
additional financing when needed would have a material adverse effect on the
Company, requiring it to curtail and possibly cease its operations. In addition,
any additional equity financing may involve substantial dilution to the
interests of the Company's then existing stockholders. See "Use of Proceeds" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."

    Uncertainty of Market Acceptance of Products. The future success of the
Company is largely dependent upon market acceptance of its FireWall/Plus family
of software products. The network security market is at an early stage of
development and is rapidly evolving. Accordingly, demand for the Company's
products and market acceptance are subject to a high level of uncertainty. While
the Company believes that its FireWall/Plus family of software products offers
advantages over competing products for network security, sales of FireWall/Plus
products since introduction (June 1995) through March 31, 1998 have been only
$2,437,000. There can be no assurance that FireWall/Plus will gain market
acceptance. Revenues from such products depend on a number of factors, including
the influence of market competition, technological changes in the network
security market, the Company's ability to design, develop and introduce
enhancements on a timely basis, and the ability of the Company to successfully
establish and maintain distribution channels. Moreover, there are commercially
available competitive products, offered by companies with significantly greater
resources than the Company, which have comparable or more favorable price
characteristics and which may be perceived to have performance characteristics
comparable to the Company's products. In addition, the Company anticipates the
introduction of additional competitive products, particularly if the demand for
network security products continues to increase. Existing and future competition
may make it more difficult to achieve market acceptance for FireWall/Plus.
Additionally, potential customers may be reluctant to purchase the Company's
products due to significant investments in other network security products.
Consequently, although the Company intends to utilize a significant portion of
the proceeds of this offering to expand its marketing and sales activities,
there can be no assurance that such funds will be sufficient, that the Company's
increased marketing efforts and expenditures will result in significant levels
of revenue or that the FireWall/Plus family of products will achieve significant
market acceptance. Moreover, a highly publicized breach of network security
involving the Company's products could adversely affect public


                                       8



perception of, and confidence in, the Company's products. See "Use of Proceeds,"
"Business - Sales and Marketing" and "Business -- Competition."

    Limited Marketing Capabilities and Experience; Dependence Upon Third-Party
Marketing Arrangements. The Company has not yet undertaken significant marketing
efforts relating to product commercialization, has limited marketing experience
and has limited financial, personnel and other resources to undertake extensive
marketing activities independently. Accordingly, the Company has relied and
intends to continue to rely to a large extent on arrangements with third parties
for the marketing and distribution of its products, including arrangements with
VARs, systems integrators, resellers, distributors and OEMs. The Company has
only recently entered into marketing arrangements with most of its distributors
and, to date, most of such arrangements have generated limited revenues. For the
year ended December 31, 1997 and the three months ended March 31, 1998, the
Company's five largest distributors accounted for an aggregate of approximately
28% and 40% of the Company's revenues, respectively. Trusted Information
Systems, Inc. (as a result of a non-refundable pre-paid royalty) and Electronic
Data Systems Corporation ("EDS") accounted for 21% and 14%, of the Company's
revenues, respectively, for the year ended December 31, 1997, and The Sabre
Group, Inc. and Omnicon Systems, Inc. accounted for 24% and 13% of the Company's
revenues, respectively, for the three months ended March 31, 1998. The Company's
prospects will be dependent upon its ability to develop and maintain strategic
marketing relationships with additional third parties and upon the marketing and
distribution efforts of its third-party distributors. While the Company believes
that the third parties with which it enters into marketing arrangements have an
economic incentive to commercialize the Company's products, the time and
resources devoted to these activities will be contributed and controlled by such
third parties. Many of the Company's third-party distributors represent various
product lines, including those competing with the Company's products. A decline
in the prospects of key distributors could have an adverse effect on the
Company. There can be no assurance that the Company will be able, for financial
or other reasons, to finalize any additional third-party distribution or
marketing arrangements, maintain its existing marketing and distribution
arrangements or that any such arrangements will result in the successful
commercialization of the Company's products. See "Business - Sales and
Marketing."

    Competition. The network security market in general, and the firewall
product market in particular, is characterized by intense competition and
rapidly changing business conditions, customer requirements and technologies.
The Company believes that the principal competitive factors affecting the market
for network security products include security effectiveness, scope of product
offerings, name recognition, product features, distribution channels, price,
ease of use and customer service and support. Currently, the Company's principal
competitors include AXENT Technologies Inc., Bay Networks, Inc., CheckPoint
Software Technologies, Ltd., Cisco Systems, Inc., Compaq Computer Corporation,
Cyberguard Corp., International Business Machines Corporation, ISS Group, Inc.,
Microsoft Corporation, Network Associates, Inc. and Secure Computing
Corporation. Due to the rapid expansion of the network security market, the
Company may face competition from new entrants to the firewall product market.
Most of the Company's current and potential competitors have longer operating
histories, greater name recognition, larger installed customer bases and possess
substantially greater financial, technical and marketing and other competitive
resources than the Company. As a result, the Company's competitors may be able
to adapt more quickly to new or emerging technologies and changes in customer
requirements or to devote greater resources to the promotion and sale of their
products than the Company. While the Company believes that its firewall products
do not compete against manufacturers of other types of security products (such
as encryption 




                                       9




and authentication products), there can be no assurance that potential customers
will not perceive the products of such other companies as substitutes for the
Company's products. In addition, certain of the Company's competitors may
determine for strategic reasons to consolidate, to substantially lower the price
of their network security products or to bundle their products with other
products, such as hardware or other enterprise software products. Accordingly,
it is possible that new competitors and alliances among competitors may emerge
and rapidly acquire significant market share. There can be no assurance that the
Company's current and potential competitors will not develop products that may
be more effective than the Company's current or future products or that the
Company's products would not be rendered obsolete or less marketable by evolving
technologies or changing consumer demands or that the Company will otherwise be
able to compete successfully. Increased competition for firewall products may
result in price reductions and reduced gross margins and may adversely effect
the Company's ability to gain market share, any of which would adversely affect
the Company's business, operating results and financial condition. See "Business
- - Competition."

    Rapid Technological Change; Potential Product Obsolescence. The network
security industry is characterized by rapid technological advances, increasingly
sophisticated and changing customer requirements, frequent new product
introductions and enhancements, new and continuously evolving network security
threats and attack methodologies and evolving industry standards in computer
hardware and software technology. As a result, the Company must continually
change and improve its products in response to such advances and changes in
operating systems, application software, computer and communications hardware,
networking software, programming tools and computer language technology. The
introduction of products embodying new technologies and the emergence of new
industry standards may render existing products obsolete or unmarketable. The
Company's future operating results will depend upon the Company's ability to
enhance its current products and to develop and introduce new products on a
timely basis that address the increasingly sophisticated needs of the
marketplace and that keep pace with technological developments, new competitive
product offerings and emerging industry standards. There can be no assurance
that the Company will be successful in developing and marketing new products or
product enhancements that respond to technological change and evolving industry
standards and customer requirements, that the Company will not experience
difficulties that could delay or prevent the successful development,
introduction and marketing of these products, or that any new products and
product enhancements will adequately meet the requirements of the marketplace
and achieve market acceptance. In the event that the Company does not respond
adequately to the need to develop and introduce new products or enhancements of
existing products in a timely manner in response to changing market conditions
or customer requirements, the Company's business, operating results and
financial condition will be materially adversely affected. See "Business -
Product Development."

    Unproven Market for Internal Network Security Products. Many of the
Company's competitors in the firewall market have largely devoted their
resources to the development and marketing of perimeter firewall products ("IP
Firewalls") designed primarily to protect an internal network from internet
based security threats or threats from within intranets. While TCP/IP is a
dominant network transport protocol, network environments often use other
network transport protocols such as Novell's IPX, Digital Equipment's DECnet and
IBM's SNA. The Company believes that the ability of the FireWall/Plus technology
to filter all commonly used network transport protocols and reside in multiple
locations throughout the enterprise network offers significant advantages as a
security product for internal networks. However, the Company's limited sales to
date have not established that, in fact, this is a significant marketing
advantage. The Company's future

success depends in large part on the Company's ability to successfully market
its technology and the increased awareness and demand in the market for the need
to address security threats that arise from within internal networks which may
require substantial marketing efforts and the expenditure of significant funds.
Furthermore, firewall vendors and other vendors of network security products
with substantially greater financial, technical and marketing resources than the
Company may modify existing security products or develop new products which
would address the internal network security market. The Company's failure to
successfully implement marketing efforts emphasizing the internal network
security market would have a material adverse effect on its business, financial
condition and results of operations in the future. See "Business - Network-1
Strategy" and "Business - FireWall/Plus Technology."

    Significant Fluctuations in Quarterly Operating Results. The Company
anticipates significant quarterly fluctuations in its operating results in the
future. The Company generally ships orders for commercial products as they are
received and, as a result, does not have any material backlog. As a result,
quarterly revenues and operating results depend on the volume and timing of
orders received during the quarter, which are difficult to forecast. Operating
results may also fluctuate on a quarterly basis due to factors such as the
demand for the Company's products, purchasing patterns and budgeting cycles of
customers, the introduction of new products and product enhancements by the
Company or its competitors, market acceptance of new products introduced by the
Company or its competitors and the size, timing, cancellation or delay of
customer orders, including cancellation or delay in anticipation of new product
introduction or enhancement. Therefore, comparisons of quarterly operating
results may not be meaningful and should not be relied upon, nor will they
necessarily reflect the Company's future performance. Because of the foregoing
factors, it is likely that in some future quarters the Company's operating
results will be below the expectations of public market analysts and investors.
In such event, the price of the Common Stock would likely be materially
adversely affected. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."

    Proposed Expansion; Management of Growth; Need for Qualified Personnel.
Following the consummation of this offering, the Company intends to use a
substantial portion of the proceeds to expand its current level of operations
and expects to significantly increase the number of its employees. This growth
will result in an increase in responsibilities placed upon the Company's
management and will place added pressures on the Company's operating and
financial resources. The Company's success will be dependent in part on its
ability to manage its growth, recruit additional management personnel, expand
its sales and marketing personnel and research and development staff, improve
its operational and financial systems, expand its customer support functions and
train, motivate and manage additional employees, monitor operations and control
costs. Competition with respect to the recruiting of highly qualified personnel
in the software industry is intense and many of the Company's competitors have
significantly greater resources than the Company. The Company's ability to
attract and assimilate new personnel will be critical to the Company's
performance and there can be no assurance that the Company will be successful in
attracting and retaining the personnel it requires to enhance its products,
develop new products and conduct its operations successfully. Moreover, the
Company may seek to expand its operations by acquiring businesses, technologies
or products which it believes are complimentary with its business. Except for
the CommHome Acquisition, the Company has no definitive plans with respect to
and is not currently involved in negotiations relating to any acquisitions. The
consummation of any such


                                       11



acquisition would place additional burden on management and financial resources.
See "Business - CommHome Systems Corp. Acquisition."

    Limited Protection of Proprietary Rights; Reliance on Trade Secrets. The
Company's success is substantially dependent on its proprietary technologies.
The Company does not hold any patents and relies on copyright and trade secret
laws, non-disclosure agreements with employees, distributors and customers,
including "shrink wrap" license agreements that are not signed by the customer,
and technical measures to protect the ideas, concepts and documentation of its
proprietary technologies and know-how to protect its intellectual property
rights. Such methods may not afford complete protection, and there can be no
assurance that third parties will not independently develop substantially
equivalent or superior technologies or obtain access to the Company's
technologies, ideas, concepts and documentation. In addition, there can be no
assurance that any confidentiality agreements between the Company and its
employees, distributors or customers will provide meaningful protection for the
Company's proprietary information in the event of any unauthorized use or
disclosure. Furthermore, the Company may be subject to additional risk as it
enters into transactions in countries where intellectual property laws are not
well developed or are poorly enforced. Legal protection of the Company's rights
may be ineffective in such countries. The inability of the Company to protect
its proprietary technologies could have a material adverse effect on the
Company. The Company also licenses from a third-party certain proxy technology
which is incorporated into its FireWall/Plus products. The Company is dependent
in part on its ability to continue to license such technology and any inability
of the Company to be able to continue to utilize such technology either as a
result of the Company's breach or the termination of the license agreement or
otherwise, in the absence of similar available technologies, could have a
material adverse effect on the Company.

    The Company received a U.S. trademark registration for the FireWall/Plus
name in December 1996. Although the Company is not aware of any challenges to
the Company's rights to use this trademark, there can be no assurance that the
use of this mark would be upheld if challenged. See "Business - Proprietary
Rights." 

    Potential Infringement on Intellectual Property Rights of Others. 
Although the Company believes that its technologies and products have been 
developed independently and do not infringe upon the proprietary rights of 
others, there can be no assurance that the Company's technologies and 
products do not and will not so infringe or that third parties will not 
assert infringement claims against the Company in the future. The Company is 
not aware of any patent infringement charge or any violation of other 
proprietary rights claimed by any third party relating to the Company or the 
Company's products. In response to certain public statements made by 
CheckPoint Software Technologies, Ltd. related to a patented technology 
referred to as "stateful inspection" (the "Checkpoint Patent"), the Company 
retained patent counsel in April 1997 to review the Checkpoint Patent as 
compared to the Company's intellectual property and associated products. 
Based upon the opinion of the Company's intellectual property counsel, the 
Company does not believe that the CheckPoint Patent will have a material 
adverse effect on the Company. If, however, the Company's technologies or 
products were deemed to infringe upon the Checkpoint Patent, or if the 
Company's technologies or products were deemed to infringe upon the 
proprietary rights of other third parties, the Company could become liable 
for damages or be required to modify its products or to obtain a license. As 
the number of and variety of security products being offered continue to 
increase the functionality of such products may further overlap, which could 
result in increased infringement claims by software developers, including 
infringement claims against the Company with respect to 

                                       12



    future products. There can be no assurance that the Company would be able to
modify its products or obtain a license in a timely manner, upon acceptable
terms and conditions, or at all, or that the Company will have the financial or
other resources necessary to defend a patent infringement or other proprietary
rights infringement action. Failure to do any of the foregoing could have a
material adverse effect on the Company, including possibly requiring the Company
to cease marketing its products. See "Business - Proprietary Rights."

    Dependence on Sales of Limited Product Line; Non-Recurring Revenues. Since
1996, a substantial portion of the Company's sales have been derived from the
sale of its FireWall/Plus products. For the year ended December 31, 1997 and the
three months ended March 31, 1998, sales of FireWall/Plus products accounted for
approximately 60% and 58% of the Company's revenues, respectively. A decline in
sales of FireWall/Plus products would have a material adverse effect on the
Company. In addition, sales of the Company's products are generally
non-recurring in nature. There can be no assurance that the Company will not
remain dependent upon non-recurring sales of FireWall/Plus products to a limited
number of customers, which sales could constitute a considerable portion of the
Company's revenues. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations." 

    Dependence on Continued Growth of the Internet and Internal Networks. Since
the Company's products are designed to protect internal networks from
unauthorized access and attacks via the Internet and from within internal
networks, the Company's success is substantially dependent upon the widespread
acceptance and use of the Internet, intranets and extranets as effective means
of communication and commerce. Rapid growth in the use of and interest in the
Internet, intranets and extranets is a recent phenomenon, and there can be no
assurance that acceptance and use will continue to develop or that a
sufficiently broad base of consumers will adopt and continue to use the
Internet, intranets and extranets as means of communication and commerce. The
Internet may not be accepted as a viable commercial marketplace for a number of
reasons, including potentially inadequate development of the necessary network
infrastructure or delayed development of enabling technologies and performance
improvements. If use of the Internet does not continue to grow or grows more
slowly than expected, if the infrastructure for the Internet does not
effectively support growth that may occur, or if the Internet and online
services do not become a viable commercial marketplace, market demand for the
Company's products may not develop or be maintained. See "Business -- Industry
Background."

    Focus on Windows NT Platform. Currently, the Windows NT operating system is
the principal platform for the Company's FireWall/Plus family of products.
According to a recent International Data Corporation survey, Windows NT
shipments are expected to assume a majority market share by 1999. While the
Windows NT platform is perceived to have security weaknesses, many of the
Company's competitors currently offer Windows NT based firewalls and the Company
believes that the use of Windows NT as the preferred operating system will
continue to grow dramatically over the next five years. In the event that demand
for Windows NT based firewalls declines, or other platforms become the preferred
platforms, and the Company is unable to adapt its products to the preferred
platforms on a timely basis, the Company's business, financial condition and
results of operations may be materially adversely affected. See "Business --
Industry Background" and "Business -- FireWall/Plus Technology."


    Potential Liability Exposure. Since the Company's products are network
security products and are used to prevent unauthorized access to and attacks
upon critical enterprise information, the 


                                       13




Company may be exposed to potential liability claims for damage caused to a
network as a result of an actual or alleged failure of an installed product.
Although the Company's license agreements typically contain provisions that are
designed to limit the Company's exposure to potential product liability or
related claims, including provisions that limit the Company's liability for
special, consequential or incidental damages, there can be no assurance that
such provisions will be enforceable under the laws of applicable domestic or
foreign jurisdictions. The Company's consulting engagements often involve
development, implementation and maintenance of networking systems that are
critical to the operations of its clients' businesses. The Company's failure or
inability to meet a client's expectations in the performance of its services
could harm the Company's business reputation or result in a claim for
substantial damages against the Company, regardless of the Company's
responsibility for such failure or inability. In addition, in the course of
performing services, the Company's personnel often gain access to technologies
and content which include confidential or proprietary client information. Any
unauthorized disclosure or use of such information could result in a claim for
substantial damages. The Company currently maintains product liability insurance
coverage in the amount of $1,000,000 per occurrence ($2,000,000 in the
aggregate) that, subject to customary exclusions, covers claims resulting from
failure of the Company's products or services to perform the function or to
serve the purpose intended. There can be no assurance that the Company's
insurance will be sufficient to cover potential claims or that adequate levels
of coverage will be available in the future at reasonable cost. A partially or
completely uninsured successful claim against the Company could have a material
adverse effect on the Company. See "Business - Proprietary Rights."

    Risk of Product Defects. Software products as complex as those offered by
the Company may contain undetected errors or result in failures when first
introduced or when new versions are released. In particular, the personal
computer hardware environment is characterized by a wide variety of non-standard
configurations that make pre-release testing for programming or compatibility
errors very difficult and time-consuming. Despite testing by the Company and by
current and potential customers, there can be no assurance that errors will not
be found in new products or enhancements after commencement of commercial
shipments. The occurrence of these errors could result in adverse publicity,
loss of or delay in market acceptance, claims by customers against the Company,
or could cause the Company to incur additional costs, any of which could have a
material adverse effect upon the Company's business, operating results and
financial condition. See "Business - Products" and "Business - Product
Development."

    Lengthy Sales Cycle. Licensing of the Company's software products generally
involves a significant commitment of capital by customers, with the attendant
delays frequently associated with large capital expenditures. Accordingly, the
sales cycle for the Company's products can be lengthy and generally commences at
the time a prospective customer demonstrates an interest in purchasing a
FireWall/Plus solution, typically includes a 30-day free evaluation period and
ends upon execution of a purchase order by the customer. The length of the sales
cycle varies depending on the type and sophistication of the customer and the
complexity of the operating system and may extend for periods of six to nine
months. As a result of the Company's lengthy sales cycle, sales of the Company's
products generally require the Company to make expenditures and use significant
resources prior to receipt, if any, of corresponding revenues. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."

    Licensing in Foreign Markets. The Company relies on sales of software
licenses in foreign customers for a portion of its revenues. For the years ended
December 31, 1996 and 1997 and the 



                                       14



three months ended March 31, 1998, licensing of the Company's software products
to foreign customers accounted for approximately 6.7%, 15.6% and 2.7%,
respectively, of the Company's revenues. The Company is seeking to increase the
licensing of its products in foreign markets, but there can be no assurance that
the Company will be successful or that such markets will prove to be viable. To
the extent that the Company is able to successfully expand its licenses to
foreign markets, the Company will become increasingly subject to risks inherent
in foreign trade, including shipping delays, increased collection risks, trade
restrictions, export duties and tariffs and international political, regulatory
and economic developments, all of which could have an adverse effect on the
Company's operating margins and results of operations and exacerbate the risks
inherent in the Company's business. The Company may seek to limit its exposure
to the risk of currency fluctuations by engaging in foreign currency hedging
transactions that could expose the Company to substantial risk of loss. The
Company is not currently engaged in any currency hedging or other activities
involving derivative financial instruments. The Company has limited experience
in managing international transactions and has not yet formulated a strategy to
protect the Company against currency fluctuations. See "Business - Sales and
Marketing."

    Dependence Upon Key Personnel; New Management. The success of the Company
will be largely dependent on the personal efforts of Avi A. Fogel, President and
Chief Executive Officer, William Hancock, Chief Technology Officer, and Robert
P. Olsen, Vice President of Product Management. Although the Company has entered
into employment agreements with each of Messrs. Fogel, Hancock and Olsen, the
loss of the services of any of such officers could have a material adverse
effect on the Company's business and prospects. Prior to the consummation of
this offering, the Company will obtain "key-man" life insurance on each of the
lives of Messrs. Fogel, Hancock and Olsen in the amounts of $2,000,000,
$3,000,000 and $2,000,000, respectively. Messrs. Fogel and Olsen as well as
Murray P. Fish, Chief Financial Officer, only joined the Company in May 1998. In
addition, Joseph A. Donohue, Vice President of Engineering, only joined the
Company in July 1998. There can be no assurance that such officers will become
sufficiently familiar with the Company's operations on a timely basis, or at
all. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and "Management."

    Control by Management. Upon consummation of this offering, the Company's
officers and directors, will beneficially own, in the aggregate, approximately
34.8% of the outstanding Common Stock. Accordingly, such persons will continue
to exert significant influence over the outcome of all matters submitted to a
vote of the holders of Common Stock, including the election of directors,
amendments to the Company's Certificate of Incorporation and approval of
significant corporate transactions. Such consolidation of voting power could
also have the effect of delaying, deterring or preventing a change in control of
the Company that might be beneficial to other stockholders. See "Management" and
"Principal Stockholders."

    Use of Proceeds to Repay Indebtedness and Trade Payables; Benefits to
Related Parties; Broad Discretion in Application of Proceeds. The Company has
allocated approximately $3,537,000 (27.9%) of the net proceeds of this offering
to repay outstanding indebtedness including $1,900,000 principal amount of
notes, plus accrued interest thereon, payable to Applewood Associates, L.P., a
principal stockholder of the Company, $200,000 principal amount of notes plus
accrued interest thereon, payable to CMH Capital Management Corp., whose sole
stockholder is Corey Horowitz, Chairman of the Board of Directors and a
principal stockholder of the Company, and $50,000 principal amount of a note
plus interest payable to Mr. Horowitz. Furthermore, the Company has allocated
approximately $500,000 to pay past due trade payables upon consummation of this
offering. 



                                       15



In addition, simultaneously with the consummation of this offering, the Company
is acquiring CommHome Systems Corp. ("CommHome"), of which Avi A. Fogel is
President and Chief Executive Officer and a principal stockholder, in exchange
for 35,000 shares of Common Stock and the assumption of up to $200,000 of
liabilities, of which $55,000 and $50,000 are owed to Mr. Fogel and Robert P.
Olsen, Vice President of Product Management, respectively. Messrs. Fogel and
Olsen have agreed to cancel such obligations in exchange for the issuance of
6,875 and 6,250 shares of Common Stock, respectively, upon the consummation of
this offering. Approximately $1,895,000 (14.9%) of the estimated net proceeds of
this offering has been allocated to working capital and general corporate
purposes. Management will have broad discretion as to the application of such
proceeds. Furthermore, to the extent cash flow from operations is insufficient
for such purposes, a portion of the proceeds allocated to working capital may be
utilized to pay a portion of the salary of the Company's officers (such
aggregate salaries estimated to be approximately $970,000) over the twelve
months following the consummation of this offering. See "Use of Proceeds,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Certain Transactions."

    Immediate and Substantial Dilution. This offering involves an immediate and
substantial dilution of $5.35 per share (or 66.9%) between the adjusted net
tangible book value per share of Common Stock after this offering and the
initial public offering price per share. See "Dilution."

    No Dividends. The Company has never paid any dividends on its Common Stock
and does not anticipate paying cash dividends in the foreseeable future. The
Company currently intends to retain all earnings for use in connection with the
operation and expansion of its business. The declaration and payment of future
dividends, if any, will be at the sole discretion of the Company's Board of
Directors and will depend upon a variety of factors, including future earnings,
if any, operations, capital requirements, the general financial condition of the
Company, the preferences of any series of Preferred Stock which may be
designated in the future, the general business conditions and future contractual
restrictions on payments of dividends, if any. See "Dividend Policy" and
"Description of Securities - Common Stock."

    Shares Eligible for Future Sale; Registration Rights. Upon the consummation
of this offering, the Company will have 4,508,369 shares of Common Stock
outstanding, of which the 1,875,000 shares being offered hereby will be freely
tradeable without restriction or further registration under the Securities Act.
All of the remaining 2,633,369 shares of Common Stock outstanding are
"restricted securities," as that term is defined in Rule 144 promulgated under
the Securities Act, and in the future may be sold only pursuant to an effective
registration statement under the Securities Act, in compliance with the
exemption provisions of Rule 144, on various dates commencing 90 days following
the date of this Prospectus, or pursuant to another exemption under the
Securities Act. The Company has granted certain registration rights with respect
to an aggregate of 1,117,435 shares of Common Stock, and the Company has granted
the Underwriter demand and piggyback registration rights with respect to the
shares of Common Stock issuable upon exercise of the Underwriter's Warrants. No
prediction can be made as to the effect, if any, that sales of such securities
or the availability of such securities for sale will have on the market prices
prevailing from time to time. While all of the Company's securityholders,
including the Company's officers and directors, have agreed not to (i) sell or
otherwise dispose of any shares of Common Stock in any public market transaction
(including pursuant to Rule 144) or (ii) exercise any registration rights for a
period of twelve months following the date of this Prospectus without the
Underwriter's prior written consent, the possibility that a substantial number
of the Company's securities may be sold in the public market 



                                       16



may adversely affect prevailing market prices for the Common Stock and could
impair the Company's ability to raise capital through the sale of its equity
securities. See "Description of Securities" and "Shares Eligible for Future
Sale."

    Significant Outstanding Options and Warrants; Potential Adverse Effect on
Market Price of Common Stock. Upon the consummation of this offering, there will
be outstanding options and warrants to purchase an aggregate of 1,242,294 shares
of Common Stock (including 187,500 shares of Common Stock issuable upon exercise
of the Underwriter's Warrants) at exercise prices ranging from $1.61 to $13.20
per share. To the extent that outstanding options and warrants are exercised,
dilution to the percentage ownership of the Company's stockholders will occur
and any sales in the public market of the Common Stock underlying such options
and warrants may adversely affect prevailing market prices for the Common Stock.
Moreover, the terms upon which the Company will be able to obtain additional
equity capital may be adversely effected since the holders of outstanding
options and warrants can be expected to exercise them at a time when the Company
would, in all likelihood, be able to obtain any needed capital on terms more
favorable to the Company than those provided in the outstanding options and
warrants. See "Management - Stock Option Plan," "Description of Securities -
"Warrants and Options" and "Underwriting."

    No Assurance of Public Market; Arbitrary Determination of Offering Price;
Possible Volatility of Market Price of Common Stock. Prior to this offering,
there has been no public trading market for the Common Stock. There can be no
assurance that a regular trading market for the Common Stock will develop after
this offering or that, if developed, it will be sustained. The initial public
offering price of the Common Stock has been determined arbitrarily by
negotiation between the Company and the Underwriter and is not necessarily
related to the assets, book value or potential earnings of the Company or any
other recognized criteria of value and may not be indicative of the prices that
may prevail in the public market. In addition, the market price for the Common
Stock following this offering may be highly volatile as has been the case with
the securities of other companies in emerging businesses. Factors such as the
Company's operating results, announcements of the Company or its competitors,
introduction of new products or technologies by the Company or its competitors
and various factors affecting the network security industry generally or the
market for firewall products in particular may have a significant impact on the
market price of the Common Stock. Additionally, in recent years, the stock
market has experienced a high level of price and volume volatility and market
prices for the stock of many companies, particularly of small and emerging
growth companies, the common stock of which trade in the over-the-counter
market, have experienced wide price fluctuations which have not necessarily been
related to the operating performance of such companies. See "Underwriting."

    Possible Delisting of Securities from Nasdaq System; Risks Relating to
Low-Priced Stocks. It is currently anticipated that the Common Stock will be
eligible for listing on Nasdaq upon the completion of this offering. In order to
continue to be listed on Nasdaq, however, the Company must maintain $2,000,000
in net tangible assets (total assets, other than goodwill, less total
liabilities), and a $1,000,000 market value of the public float. In addition,
continued inclusion requires two market-makers, a minimum bid price of $1.00 per
share and adherence to certain corporate governance provisions. The failure to
meet these maintenance criteria in the future may result in the delisting of the
Common Stock from Nasdaq, and trading, if any, in the Common Stock would
thereafter be conducted in the non-Nasdaq over-the-counter market. As a result
of such delisting, an investor could find it more difficult to dispose of or to
obtain accurate quotations as to the market value of the Common Stock.



                                       17



    In addition, if the Common Stock were to become delisted from trading on
Nasdaq and the trading price of the Common Stock were to fall below $5.00 per
share, trading in the Common Stock would also be subject to the requirements of
certain rules promulgated under the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), which require additional disclosure by broker-dealers in
connection with any trades involving a stock defined as a penny stock
(generally, any non-Nasdaq equity security that has a market price of less than
$5.00 per share, subject to certain exceptions). Such rules require the
delivery, prior to any penny stock transaction, of a disclosure schedule
explaining the penny stock market and the risks associated therewith and impose
various sales practice requirements on broker-dealers who sell penny stocks to
persons other than established customers and accredited investors (generally
defined as an investor with a net worth in excess of $1,000,000 or annual income
exceeding $200,000 individually or $300,000 together with a spouse). For these
types of transactions, the broker-dealer must make a special suitability
determination for the purchaser and have received the purchaser's written
consent to the transaction prior to the sale. The broker-dealer also must
disclose the commissions payable to the broker-dealer, current bid and offer
quotations for the penny stock and, if the broker-dealer is the sole
market-maker, the broker-dealer must disclose this fact and the broker-dealer's
presumed control over the market. Such information must be provided to the
customer orally or in writing before or with the written confirmation of trade
sent to the customer. Monthly statements must be sent disclosing recent price
information for the penny stock held in the account and information on the
limited market in penny stocks. The additional burdens imposed upon
broker-dealers by such requirements could, in the event the Common Stock were
deemed to be a penny stock, discourage broker-dealers from effecting
transactions in the Common Stock which could severely limit the market liquidity
of the Common Stock and the ability of purchasers in this offering to sell the
Common Stock in the secondary market.

    Adverse Effect of the Authorization of Preferred Stock; Anti-Takeover
Provisions Affecting Stockholders. The Company's Certificate of Incorporation
authorizes the Company's Board of Directors to issue 5,000,000 shares of "blank
check" Preferred Stock and to fix the rights, preferences, privileges and
restrictions, including voting rights, of these shares, without further
stockholder approval. The rights of the holders of Common Stock will be subject
to and may be adversely affected by the rights of holders of any Preferred Stock
that may be issued in the future. The ability to issue Preferred Stock without
stockholder approval could have the effect of making it more difficult for a
third party to acquire a majority of the voting stock of the Company thereby
delaying, deferring or preventing a change in control of the Company. Moreover,
following the consummation of this offering, the Company will be subject to the
State of Delaware's "business combination" statute, which prohibits a
publicly-traded Delaware corporation from engaging in various business
combination transactions with any of its 15% stockholders for a period of three
years after the date of the transaction in which the person became an
"interested stockholder," unless certain approvals are obtained or other events
occur. The statute could prohibit or delay mergers or other attempted takeovers
or changes in control with respect to the Company and, accordingly, may
discourage attempts to acquire the Company. See "Description of Securities."

    Tax Loss Carryforward. The Company's net operating loss carryforwards
("NOLs") expire in the years 2009 to 2012. Under Section 382 of the Internal
Revenue Code of 1986, as amended, utilization of prior NOLs is limited after an
ownership change, as defined in Section 382, to an annual amount equal to the
value of the corporation's outstanding stock immediately before the date of the
ownership change multiplied by the federal long-term date exempt tax rate. The
additional equity financing obtained by the Company in connection with recent
financings and this offering may result in an ownership change and, thus, in a
limitation on the Company's use of its prior NOLs. In the 



                                       18



event the Company achieves profitable operations, any significant limitation on
the utilization of its NOLs would have the effect of increasing the Company's
tax liability and reducing net income and available cash reserves. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and Note H to Notes to Financial Statements.

    Limitations on Liability of Directors and Officers. The Company's
Certificate of Incorporation includes provisions to eliminate, to the full
extent permitted by Delaware General Corporation Law as in effect from time to
time, the personal liability of directors of the Company for monetary damages
arising from a breach of their fiduciary duties as directors. The Certificate of
Incorporation also includes provisions to the effect that the Company'shall, to
the maximum extent permitted from time to time under the law of the State of
Delaware, indemnify any director or officer to the extent that such
indemnification and advancement of expense is permitted under such law, as it
may from time to time be in effect. In addition, the Company's By-laws require
the Company to indemnify, to the fullest extent permitted by law, any director,
officer, employee or agent of the Company for acts which such person reasonably
believes are not in violation of the Company's corporate purposes as set forth
in the Certificate of Incorporation. See "Management - Limitation of Liability
and Indemnification Matters."



                                       19




                                 USE OF PROCEEDS

    The net proceeds to the Company from the sale of the 1,875,000 shares of
Common Stock offered hereby, (after deducting underwriting discounts and
commissions and other expenses of the offering) are estimated to be
approximately $12,692,000 ($14,672,000 if the Underwriter's over-allotment
option is exercised in full). The Company expects to use the net proceeds

(1)  Represents (i) approximately $2,460,000 for sales, marketing and
     promotional activities related to the Company's software products and (ii)
     approximately $1,400,000 for the salaries and related costs of up to 15
     additional sales and marketing personnel. See "Business - Sales and
     Marketing."

(2)  Represents amounts to repay (i) $3,250,000 principal amount of promissory
     notes (the "Notes") issued in private offerings from February 1997 through
     May 1998, plus estimated accrued interest thereon at annual rates between
     6% and 8%, including $1,900,000, $200,000 and $50,000 principal amount of
     Notes held by Applewood Associates, L.P., a principal stockholder of the
     Company, CMH Capital Management Corp., a corporation wholly-owned by Corey
     M. Horowitz, Chairman of the Board of Directors and a principal stockholder
     of the Company, and Mr. Horowitz, respectively, and (ii) approximately
     $95,000 of certain liabilities assumed by the Company in connection with
     the CommHome Acquisition and paid upon consummation of this offering. The
     Company used the net proceeds from the issuance of the Notes for working
     capital and general corporate purposes. See "Certain Transactions."

(3)  Represents estimated costs associated with software development, including
     the salaries of up to 17 additional software engineers and developers. See
     "Business - Product Development."

(4)  Represents expenditures to purchase hardware and software as well as
     servers and test equipment for the Company's operations.

(5)  Represents estimated past due trade payables to be paid upon the
     consummation of this offering. See Financial Statements.



                                       20



(6)  Represents costs associated with relocating the Company's principal office
     location to the Boston, Massachusetts area, including rent and related
     costs. See "Business - Facility."

(7)  Represents amounts which may be used to pay a portion of the compensation
     for executive officers (such aggregate salaries are estimated to be
     $970,000 during the twelve months following the consummation of this
     offering), rent, trade payables, consulting fees and professional fees.

    If the Underwriter's over-allotment option is exercised in full, the Company
will realize additional net proceeds of $1,980,000, which will be allocated to
working capital and general corporate purposes.

    The allocation of the net proceeds from this offering set forth above
represents the Company's best estimate based upon its currently proposed plans
and assumptions relating to its operations and certain assumptions regarding
general economic conditions. If any of these factors change, the Company may
find it necessary or advisable to reallocate some of the proceeds within the
above-described categories or to use portions thereof for other purposes. The
Company may also use a portion of the net proceeds for the acquisition of
businesses, technologies, or products which it believes are complimentary to
those of the Company, although no such acquisitions are planned or being
negotiated as of the date of this Prospectus, except for the acquisition of
CommHome. See "Business - CommHome Systems Corp. Acquisition."

    Based on currently proposed plans and assumptions relating to its
operations, and implementation of its business plan (including the timetable of
costs and expenses associated with, and success of, its marketing efforts)
the Company anticipates that the net proceeds of this offering, together with
projected revenues from operations, will be sufficient to fund the Company's
operations and capital requirements for approximately twelve months following
the consummation of this offering. There can be no assurance, however, that such
funds will not be expended prior thereto due to unanticipated changes in
economic conditions or other unforeseen circumstances. In the event the
Company's plans change or its assumptions change or prove to be inaccurate (due
to unanticipated expenses, difficulties, delays or otherwise) or the net
proceeds of this offering and projected revenues otherwise prove to be
insufficient to fund the implementation of the Company's business plan or
working capital requirements, the Company could be required to seek additional
financing sooner than currently anticipated. The Company has no current
arrangements with respect to any additional financing. Consequently, there can
be no assurance that any additional financing will be available to the Company
when needed, on commercially reasonable terms or at all.

    Proceeds not immediately required for the purposes described above will be
invested principally in United States government securities, short-term
certificates of deposit, or other similar short-term, interest bearing
investments.

                                    DILUTION

    The difference between the initial public offering price per share of Common
Stock and the net tangible book value per share of Common Stock after this
offering constitutes the dilution to investors in this offering. Net tangible
book value per share is determined by dividing the net tangible book value of
the Company (total tangible assets less total liabilities) by the number of
outstanding shares of Common Stock.

    At March 31, 1998, the negative net tangible book value of the Company was
($572,000) or $(.34) per share ($.07 per share, on a pro forma basis after
giving effect to the Pro Forma Adjustments(see footnote 2 of "Prospectus
Summary--Summary Financial Information")). After also giving effect to the sale
by the Company of the 1,875,000 shares of Common Stock offered hereby (after
deducting underwriting discounts and commissions and estimated expenses of this
offering) and the Additional Adjustments (see footnote 3 of "Prospectus Summary
- -- Summary Financial Information"), the adjusted net tangible book value of the
Company at March 31, 1998 would have been $11,935,000, or $2.65 per share,
representing an immediate increase in net tangible book value of $2.58 per share
to the existing stockholders and an immediate dilution of $5.35 per share to new
investors. The following table illustrates the foregoing information with
respect to dilution to new investors on a per share basis:

    The following table sets forth, with respect to the Company's existing
stockholders (after giving effect to the Pro Forma Adjustments and the
Additional Adjustments) and new investors in this offering, a comparison of the
number of shares of Common Stock acquired from the Company, the percentage
ownership of such shares, the total consideration paid, the percentage of total
consideration paid and the average price per share.

    The above tables assume no exercise of the Underwriter's over-allotment
option. If such option is exercised in full, the new investors will have paid
$17,250,000 for 2,156,250 shares of Common Stock, representing approximately
70.5% of the total consideration, for 45.0% of the total number of shares of
Common Stock outstanding. In addition, the above tables do not give effect to
shares issuable upon exercise of outstanding warrants and options to purchase
1,242,294 shares of Common Stock, including options to purchase 423,908 shares
of Common Stock issued under the Stock Option Plan and 187,500 shares of Common
Stock issuable upon exercise of the Underwriter's Warrants. See "Management's

                                DIVIDEND POLICY

    The Company has never declared or paid any cash dividends on its Common
Stock and does not intend to declare or pay cash or other dividends in the
foreseeable future. The Board of Directors currently expects to retain any
future earnings for use in the operation and expansion of its business. The
declaration and payment of any future dividends will be at the discretion of the
Board of Directors and will depend upon a variety of factors, including future
earnings, if any, operations, capital requirements, the general financial
condition of the Company, the preferences of any series of Preferred Stock which
may be designated in the future, the general business conditions and future
contractual restrictions on payment of dividends, if any.


                                 CAPITALIZATION

    The following table sets forth (i) the capitalization of the Company as of
March 31, 1998, (ii) the pro forma capitalization at such date after giving
effect to the Pro Forma Adjustments (see footnote 2 of "Prospectus
Summary--Summary Financial Information"), and (iii) the pro forma capitalization
as adjusted to give effect to the sale of the Common Stock offered hereby, the
anticipated application of the estimated net proceeds therefrom and the
Additional Adjustments (see footnote 3 of "Prospectus Summary -- Summary
Financial Information"). The information set forth below should be read in
conjunction with the Financial Statements and Notes thereto and "Management's
Discussion and Analysis of Financial Condition and Results of Operations."

                      MANAGEMENT'S DISCUSSION AND ANALYSIS

                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

    The following discussion and analysis should be read in conjunction with the
Company's Financial Statements, including the Notes thereto, included elsewhere
in this Prospectus. Except for the historical information contained herein, this
discussion contains forward-looking statements that involve risks and
uncertainties, including, without limitation, those concerning the Company's
strategy and growth plans. Because such statements involve risks and
uncertainties, actual results may differ materially from those expressed or
implied by such forward-looking statements. Factors that could cause such
differences include, but are not limited to, those discussed under "Risk
Factors."

General

    The Company develops, markets, licenses and supports a family of network
security software products designed to provide comprehensive security to
computer networks including Internet based systems and internal networks and
computing resources. The Company also offers to its customers a full range of
consulting services in network security, network design and support. From
inception (July 1990) through December 31, 1994, the Company was primarily
engaged in providing consulting and training services. In 1995, the Company
began to shift its focus from consulting and training to the development and
marketing of network security software products. The Company introduced its
first FireWall/Plus software product in June 1995. Accordingly, the Company has
a limited relevant operating history as a software developer upon which an
evaluation of its prospects and future performance can be made. Such prospects
must be considered in light of the risks, expenses and difficulties frequently
encountered in the operation and expansion of a new business and the shift from
research and product development to commercialization of products based on
rapidly changing technologies in a highly specialized and emerging market. The
Company will be required to significantly expand its product and development
capabilities, introduce new products, introduce enhanced features to existing
products, expand its in-house sales force, establish and maintain distribution
channels through third-party vendors, increase marketing expenditures, further
expand its management team and attract additional qualified personnel. In
addition, the Company must adapt to the demands of an emerging and rapidly
changing computer network security market, intense competition and rapidly
changing technology and industry standards. There can be no assurance that the
Company can successfully address such risks, and the failure to do so would have
a material adverse effect on the Company's business, results of operations and
financial condition.

    To date, the Company has incurred significant losses and, at March 31, 1998,
had an accumulated deficit of $8,167,000. Inasmuch as the Company intends to
increase its level of activities following the consummation of this offering and
will be required to make significant up-front capital expenditures in connection
with its sales and marketing and continuing research and product development
efforts, the Company anticipates that losses will continue until such time, if
ever, as the Company is able to attain sales levels sufficient to support its
operations. There can be no assurance that the Company will ever achieve
profitable operations. The Company's independent auditors have included an
explanatory paragraph in their report on the Company's financial statements for
the year ended December 31, 1996 and December 31, 1997, stating that certain
factors raise substantial doubt about the Company's ability to continue as a
going concern.


                                       25



    The Company has only recently employed certain members of senior management,
including Avi A. Fogel, President and Chief Executive Officer, Robert P. Olsen,
Vice President of Product Management, Murray P. Fish, Chief Financial Officer,
and Joseph A. Donohue, Vice President of Engineering. In addition, the Company
intends to hire approximately 17 additional software engineers and developers
and 15 additional sales and marketing personnel within twelve months of
consummation of this offering, as well as expand its finance and administrative
staff and increase expenses for employee benefits, facilities, consulting,
insurance, and other general operating expenses. See "Business -- Sales and
Marketing," "Business -- Product Development" and "Management -- Employment
Agreements."

    The Company's FireWall/Plus family of software products has not yet achieved
market acceptance. The future success of the Company is largely dependent upon
market acceptance of its FireWall/Plus family of software products. While the
Company believes that its FireWall/Plus family of software products offer
advantages over competing products for network security, license revenue from
FireWall/Plus products since their introduction (June 1995) through March 31,
1998 has only been $2,437,000. There can be no assurance that FireWall/Plus will
gain significant market acceptance. Revenue from such commercial products depend
on a number of factors, including the influence of market competition,
technological changes in the network security market, the Company's ability to
design, develop and introduce enhancements on a timely basis, and the ability of
the Company to successfully establish and maintain distribution channels. The
failure of FireWall/Plus to achieve significant market acceptance, as a result
of competition, technological change or other factors, would have a material
adverse effect on the Company's business, operating results and financial
condition.

    The Company's revenues are generated primarily from product license fees for
the use of the Company's software products (license revenues) and service fees
for consulting services, maintenance and training (service revenues). Revenues
from licenses are recognized upon (i) delivery of the software or, if the
customer has evaluation software, delivery of the software key, and (ii)
issuance of the related license, assuming that no significant vendor obligations
or customer acceptance rights exist. In October 1997, the American Institute of
Certified Public Accountants issued Statement of Position ("SOP") No. 97-2,
Software Revenue Recognition, which the Company adopted, effective January 1,
1997. Such adoption had no effect on the Company's methods of recognizing
revenue from its license and maintenance activities. Prior to 1997, the
Company's revenue policy was in accordance with the preceding authoritative
guidance provided by SOP No. 91-1, Software Revenue Recognition.

    The Company recognizes service revenue upon delivery of the service or
ratably over the period of service. Consulting and training fees are recognized
as such services are performed. Annual maintenance, which may be purchased in
conjunction with the licensing of a product, is offered for an annual fee
generally equal to 15% of the then current license fee and is recorded as
service revenue ratably over the contract term.

    The Company markets and licenses its products and services primarily through
third parties, such as VARs, systems integrators, resellers, distributors and
OEMs, and to a lesser extent, through the Company's limited in-house sales
force. Licenses through distributors typically have a lower gross margin than
in-house generated licenses since distributors usually receive discounts.
Revenues from third-party distributors accounted for approximately 23% and 50%
of the Company's license 



                                       26




revenues for the years ended December 31, 1996 and 1997, respectively. The
Company expects that the percentage of license revenues generated from
third-party distributors to increase in future periods. Pricing is based upon
the number of concurrent connections, the nature of the user's operating system
and whether hardware is needed. Selling and marketing expenses are expected to
increase as a result of proposed expansion of distribution channels and
marketing programs and hiring of additional personnel.

    The Company has committed significant product and development resources to
its FireWall/Plus family of products. The Company's anticipated levels of
expenditures for product development are based on its plans for product
enhancements and new product development. The Company capitalizes software
development costs, net of amortization, in accordance with Statement of
Financial Accounting Standards No. 86. These costs consist of salaries,
consulting fees and applicable overhead. The Company intends to use a portion of
the proceeds of this offering to significantly increase its product development
expenditures. See "Business - Product Development."

Results of Operations

Three Months Ended March 31, 1998 Compared to Three Months Ended March 31, 1997

    Revenues decreased by $140,000 or 29%, from $479,000 for the three months
ended March 31, 1997 to $339,000 for the three months ended March 31, 1998, as a
result of decreased license revenues. License revenues decreased by $151,000 or
44%, from $346,000 for the three months ended March 31, 1997 to $195,000 for the
three months ended March 31, 1998, primarily due to a lack of financial
resources for marketing of its software products during the three months ended
March 31, 1998 and certain initial product licensing payments received from
international resellers during the three months ended March 31, 1997. Service
revenues increased by $11,000 or 8%, from $133,000 for the three months ended
March 31, 1997 to $144,000 for the three months ended March 31, 1998. The
increase in service revenues is attributable to a large consulting project
serviced during the three months ended March 31, 1998.

    Cost of licenses consists of the costs of media, documentation, product
packaging, production, product royalties, amortization of software development
costs and the cost of hardware associated with "turn-key" solutions. Cost of
licenses increased by $72,000 or 69%, from $105,000 for the three months ended
March 31, 1997 to $177,000 for the three months ended March 31, 1998,
representing 30% and 91% of license revenues, respectively. The increase in cost
of licenses in dollar amount and as a percentage of license revenues resulted
primarily from increased amortization of software costs and hardware costs
associated with sales of FireWall/Plus Premier Version, which is a turn-key
solution and includes computer hardware and, therefore, has a lower gross
margin. Cost of licenses as a percentage of license revenues may fluctuate from
period to period due to changes in product mix, changes in the number or size of
transactions recorded in a given period or an increase or decrease in licenses
of products which would require the Company to pay royalties to third parties.



                                       27




    Cost of services consist of the costs of salary, fringe benefits and
overhead associated with consulting services. Cost of services decreased by
$1,000 or 1%, from $76,000 for the three months ended March 31, 1997 to $75,000
for the three months ended March 31, 1998, representing 57% and 52% of service
revenues, respectively.

    Gross profit decreased from $298,000 for the three months ended March 31,
1997 to $87,000 for the three months ended March 31, 1998, representing 62% and
26% of revenues, respectively. The decrease in gross profit was due to decreased
license revenues and the increase in cost of sales as a result of increased
amortization of software costs and hardware costs associated with sales of
FireWall/Plus Premier Version.

    Product development costs consist of salaries, benefits, travel and related
costs of the Company's product development personnel, including consulting fees,
the costs of computer equipment used in product and technology development and
third-party development contracts. Product development costs increased $111,000
or 114%, from $97,000 for the three months ended March 31, 1997 to $208,000 for
the three months ended March 31, 1998, representing 20% and 61% of revenues,
respectively. The increase in product development costs in dollar amount and as
a percentage of revenues was due primarily to the capitalization of $283,333 and
$0 of product development costs associated with the development and enhancement
of its FireWall/Plus family of products during the three months ended March 31,
1997 and the three months ended March 31, 1998, respectively. During the three
months ended March 31, 1998, all product development costs were expensed since
they were incurred after the release of FireWall/Plus Version 4.0. The Company
currently anticipates that product development costs will increase as the
Company hires additional software engineers and developers to support the
Company's growth. See "Business - Product Development."

    Sales and marketing expenses consist primarily of salary costs, including
commissions, benefits, bonuses and travel, advertising, public relations,
consultants and trade shows. Selling and marketing expenses decreased by
$186,000 or 57%, from $326,000 for the three months ended March 31, 1997 to
$140,000 for the three months ended March 31, 1998, representing 68% and 41% of
revenues, respectively. The decrease in selling and marketing expenses was due
primarily to a decrease in marketing efforts during such period resulting from
the Company's lack of available funds.

    General and administrative expenses include employee costs, including
salary, benefits, bonuses, travel and other related expenses associated with
management, finance and accounting operations, and legal and other professional
services provided to the Company. General and administrative expenses decreased
by $222,000 or 51%, from $434,000 for the three months ended March 31, 1997 to
$212,000 for the three months ended March 31, 1998, representing 91% and 63% of
revenue, respectively. The decrease in general and administrative expenses was
due primarily to reduced professional fees, recruitment fees and travel and
entertainment expenses. The Company currently anticipates that general and
administrative expenses will increase significantly as the Company hires
additional personnel to support its growth in future periods.


                                       28



    Interest expense increased by $193,000 or 623%, from $31,000 for the three
months ended March 31, 1997 to $224,000 for the three months ended March 31,
1998, representing 6% and 66% of revenues, respectively. The increase in
interest expense was due primarily to an increase in the amortization of debt
discount for the three months ended March 31, 1998 related to private financings
consisting of notes and warrants. Interest expense is expected to be
significantly reduced following consummation of the offering since the Company
intends to use approximately $3,442,000 of the proceeds of this offering to
repay outstanding debt.

    No provision for or benefit from federal, state or foreign income taxes was
recorded for the three months ended March 31, 1997 or the three months ended
March 31, 1998 because the Company incurred net operating losses during each
period and fully reserved its deferred tax assets as their future realization
could not be determined.

    As a result of the foregoing, the net loss increased by $107,000 or 18%,
from $590,000 for the three months ended March 31, 1997 to $697,000 for the
three months ended March 31, 1998.

Year Ended December 31, 1997 Compared to Year Ended December 31, 1996

    Revenues increased by $1,342,000 or 131%, from $1,027,000 for the year ended
December 31, 1996 ("1996") to $2,369,000 for the year ended December 31, 1997
("1997"). License revenues increased by $1,008,000 or 162%, from $624,000 for
1996 to $1,632,000 for 1997, partially due to the receipt of a non-refundable
prepaid royalty of $500,000 from Trusted Information Systems, Inc. relating to
licensing certain of the Company's technology and an increase in software
licenses sold during 1997 as a result of introduction of FireWall/Plus for
Windows NT. Service revenues increased by $334,000 or 83%, from $403,000 for
1996 to $737,000 for 1997 primarily as a result of servicing a large consulting
project and an increase in the customer base which purchased maintenance
contracts during 1997. The Company's two largest customers, Trusted Information
Systems, Inc. and Electronic Data Systems Corporation ("EDS") accounted for 21%
and 14% of the Company's revenues, respectively, in 1997. The Company's revenues
from customers in the United States represented 93% of its revenues in 1996 and
84% of its revenues in 1997.

    Cost of licenses increased $58,000 or 13%, from $439,000 for 1996 to
$497,000 for 1997, representing 70% and 30% of license revenues, respectively.
The increase in the cost of licenses resulted primarily from the increased
amortization of capitalized software costs related to the Company's
FireWall/Plus for Windows NT product, hardware costs associated with sales of
FireWall/Plus Premier Version and royalties paid to third parties from product
sales. The decrease in cost of revenues as a percentage of license revenues was
due primarily to the Company's receipt in June 1997 of a $500,000 prepaid
royalty related to the license of its technology and decreased hardware costs
for resale.

    Cost of services decreased by $5,000 or 2%, from $298,000 for 1996 to
$293,000 for 1997, representing 74% and 40% of service revenues, respectively.
The decrease in cost of services as a percentage of service revenues was due
primarily to the increase in service revenues which did not require increased
personnel.



                                       29



    Gross profit increased from $290,000 for 1996 to $1,579,000 for 1997
representing 28% and 67% of revenues, respectively. The increase in gross profit
was due to increased license revenue of $1,008,000, including receipt of a
$500,000 prepaid royalty in June 1997 and a $334,000 increase in revenue from
software licenses.

    Product development costs decreased by $67,000 or 7%, from $984,000 for 1996
to $917,000 for 1997, representing 96% and 39% of revenues, respectively. The
decrease in product development costs was due primarily to an increased portion
of time spent by developers on the development of the second release of the
FireWall/Plus Windows NT product and the capitalization of such costs. During
1996 and 1997, the Company capitalized $750,000 and $850,000, respectively, of
product development expenditures associated with the development and enhancement
of its FireWall/Plus family of products.

    Sales and marketing expenses decreased by $688,000 or 43%, from $1,614,000
for 1996 to $926,000 for 1997, representing 157% and 39% of revenues,
respectively. The decrease in sales and marketing expenses in dollar amount and
as a percentage of revenues was due primarily to a $526,000 decrease in
advertising expenses and the reduction of trade shows and related travel due to
the Company's lack of funds for sales and marketing, as well as the Company's
receipt of $500,000 of prepaid royalties in June 1997 and a $508,000 increase in
revenues from software licenses.

    General and administrative expenses decreased by $358,000 or 19%, from
$1,931,000 for 1996 to $1,573,000 for 1997, representing 188% and 66% of revenue
for 1996 and 1997, respectively. The decrease in general and administrative
expenses in dollar amount and as a percentage of revenue in 1997 was due
primarily to a charge of $683,000 related to the issuance of warrants and shares
of Common Stock to advisory board members and others for services rendered in
March 1996 and reduced professional fees, recruiting fees, office supplies and
stationary, repairs and maintenance contracts, travel and bad debt expenses.

    Interest expense increased by $293,000 or 113%, from $260,000 for 1996 to
$553,000 for 1997, representing 25% and 23% of revenue for 1996 and 1997,
respectively. The increase in interest expense was due primarily to increased
amortization of debt discount as a result of the issuance of $1,500,000
principal amount promissory notes and warrants to purchase 210,628 shares of
Common Stock during 1997. Debt discount is amortized over the life of the debt
instrument.

    No provision for or benefit from federal, state or foreign income taxes was
recorded for 1996 or 1997 because the Company incurred net operating losses for
each year and fully reserved its deferred tax assets as their future realization
could not be determined.

    As a result of the foregoing, the net loss decreased by $2,109,000 or 47%,
from $4,499,000 for 1996 to $2,390,000 for 1997.

Liquidity and Capital Resources

    The Company's capital requirements have been and will continue to be
significant, and its cash requirements have been exceeding its cash flow from
operations. At March 31, 1998, the Company had $67,000 of cash and cash
equivalents and a working capital deficit of $2,283,000 due to, among other
things, costs associated with financing its product development efforts. The



                                       30




Company has financed its operations primarily through private sales of equity
and debt securities. Net cash used in operating activities was $708,000 and
$383,000 during 1997 and the three months ended March 31, 1998, respectively.
Net cash used in operating activities for 1997 was primarily attributable to a
net loss of $2,390,000 and an increase in accounts receivable of 309,000 which
was partially offset by increases in accounts payable, accrued expenses and
accrued fees of $744,000, and amortization of debt discount of $500,000 and
depreciation and amortization of $481,000. The Company's operating activities
during 1996, 1997 and the three months ended March 31, 1998 were financed
primarily with $3,948,000 of net proceeds from the sale of Common Stock with
respect to a private placement completed in March 1996, $1,500,000 of net
proceeds from the issuance of $1,500,000 principal amount of notes and warrants
to purchase 210,628 shares of Common Stock in 1997 and $400,000 of net proceeds
from the issuance of $400,000 principal amount of notes and warrants to purchase
74,495 shares of Common Stock for the three months ended March 31, 1998. Since
March 31, 1998, the Company has financed its activities with $1,350,000 of net
proceeds from the issuance of $1,350,000 principal amount of notes and warrants
to purchase 251,423 shares of Common Stock. The Company intends to use a portion
of the net proceeds of this offering to repay the entire principal amount of
$3,250,000 and interest accrued on such outstanding notes. The Company does not
currently have a line of credit from a commercial bank or other institution.

    The Company is dependent on the proceeds of this offering to implement its
business plan and finance its working capital requirement. The Company
anticipates, based on currently proposed plans and assumptions relating to the
implementation of its business plan (including the timetable of, costs and
expenses associated with, and success of, its marketing efforts), that the net
proceeds of this offering, together with projected revenues from operations,
will be sufficient to satisfy the Company's operations and capital requirements
for approximately twelve months following the consummation of this offering.
There can be no assurance, however, that such funds will not be expended prior
thereto due to unanticipated changes in economic conditions or other unforeseen
circumstances. In the event the Company's plans change or its assumptions change
or prove to be inaccurate (due to unanticipated expenses, difficulties, delays
or otherwise) or the net proceeds of this offering and projected revenues
otherwise prove to be insufficient to fund the implementation of the Company's
business plan or working capital requirements, the Company could be required to
seek additional financing sooner than currently anticipated. The Company has no
current arrangements with respect to any additional financing. Consequently,
there can be no assurance that any additional financing will be available to the
Company when needed, on commercially reasonable terms or at all. Any inability
to obtain additional financing when needed would have a material adverse effect
on the Company, requiring it to curtail and possibly cease its operations. In
addition, any additional equity financing may involve substantial dilution to
the interests of the Company's then existing stockholders.

Fluctuations in Operating Results

    The Company anticipates significant quarterly fluctuations in its operating
results in the future. The Company generally ships orders for commercial
products as they are received and, as a result, does not have any material
backlog. As a result, quarterly revenues and operating results depend on the
volume and timing of orders received during the quarter, which are difficult to
forecast. Operating results may fluctuate on a quarterly basis due to factors
such as the demand for the Company's products, purchasing patterns and budgeting
cycles of customers, the introduction of new products and product enhancements
by the Company or its competitors, market acceptance of 


                                       31



new products introduced by the Company or its competitors and the size, timing,
cancellation or delay of customer orders, including cancellation or delay in
anticipation of new product introduction or enhancement. In addition, the
Company's consulting revenues tend to fluctuate as projects, which may continue
over several quarters, are undertaken or completed. Therefore, comparisons of
quarterly operating results may not be meaningful and should not be relied upon,
nor will they necessarily reflect the Company's future performance. Because of
the foregoing factors, it is likely that in some future quarters the Company's
operating results will be below the expectations of public market analysts and
investors. In such event, the price of the Common Stock would likely be
materially adversely affected.

    Licensing of the Company's products generally involves a significant
commitment of capital by customers, with the attendant delays frequently
associated with large capital expenditures. Accordingly, the sales cycle for the
Company's products can be lengthy and generally commences at the time a
prospective customer demonstrates an interest in licensing a FireWall/Plus
solution, typically includes a 30-day free evaluation period and ends upon
execution of a purchase order by the customer. The length of the sales cycle
varies depending on the type and sophistication of the customer and the
complexity of the operating system and may extend for periods of six to nine
months. As a result of the Company's lengthy sales cycle, license of the
Company's products generally require the Company to make expenditures and use
significant resources prior to receipt, if any, of corresponding revenues.

Year 2000 Issue

    The Company has assessed the potential software issues associated with the
Year 2000 and believes its software products are Year 2000 compliant and,
therefore, does not expect to incur material costs related thereto. With regard
to internal computing resources utilized in its operations, the Company does not
expect to incur material costs to make such resources year 2000 compliant.

                                    BUSINESS

Overview

    The Company develops, markets, licenses and supports a family of network
security software products designed to provide comprehensive security to
computer networks, including Internet based systems and internal networks and
computing resources. The Company's FireWall/Plus family of security software
products enables an organization to protect its computer networks from internal
and external attacks and to secure organizational communications over such
internal networks and the Internet. The Company also offers its customers a full
range of consulting services in network security and network design and support
in order to build, maintain and enhance customer relationships and increase the
demand for its software products.

    The FireWall/Plus family of security solutions is designed to protect
against Internet and intranet (internal networks utilizing Internet technology
and applications based upon TCP/IP - the Internet network transport protocol)
based security threats and to address security needs that arise from within
internal networks that often utilize other network transport protocols besides
TCP/IP including, among others, Novell's IPX, Digital Equipment's DECnet and
IBM's SNA. The Company's FireWall/Plus family of firewall products operates on
the Microsoft Windows NT operating system platform. FireWall/Plus's proprietary
Interceptor Shim and filter engine software technology, with its unique ability
to handle and filter all commonly used network transport protocols, provides
organizations with a highly secure and flexible security solution. Additionally,
unlike most other firewall solutions which focus on an enterprise's connection
to the Internet, the FireWall/Plus solution can be deployed throughout the
enterprise; at the perimeter to control access to and from the Internet, between
internal networks and on application servers and desktop PCs to protect data
residing on such servers and PCs. The Company's FireWall/Plus for Windows NT
received the 1997 Internet and Electronic Commerce Conference award for "Best
Intranet Solution" and the 1997 ENT Readers Choice Award for "Best NT Firewall."

Industry Background

    A critical resource of every organization is its information and its ability
to distribute and access information throughout the enterprise. Computing has
moved from large centralized mainframes to distributed client/server
architecture consisting of interconnected personal computers dispersed
throughout an organization. Organizations utilize local area networks ("LANs")
to share information and applications internally. Many organizations have
connected LANs, including geographically dispersed networks, into wide area
networks ("WANs"). In addition, the explosive growth in telecommuting has
resulted in LANs and WANs frequently being accessed from remote locations via
traditional modem dial-up, Integrated Services Digital Network ("ISDN") and
recently introduced cable modems and Asymmetric Digital Subscriber Line ("ADSL")
modems. There is a growing use of establishing these remote connections to an
organization's central resources, via Internet links, rather than through
dedicated point-to point connections.

    This evolution from mainframe computers supporting a number of terminals,
towards networks of interconnected personal computers has resulted in a wide
range of technologies from a multitude of vendors being used within internal
networks in order to satisfy different enterprise computing requirements. As a
result, heterogeneous networks utilizing a variety of network transport



                                       33



protocols are commonplace within LANs and WANs. Although TCP/IP has become a
widely accepted network transport protocol due to the growth of the Internet and
the popularity of TCP/IP applications for use within internal networks, network
transport protocols such as IPX, DECnet, AppleTalk, and SNA among others, are
still utilized throughout networked environments, and the Company believes such
network transport protocols will continue to be utilized due to the large
investments in installed systems and applications using these protocols.
Further, computing environments often run one or more incompatible versions of
the same protocol suite for extended periods of time while converting to new
versions or to support older applications or systems which cannot use the newer
versions of a given protocol suite. In addition, Windows NT is shipped from
Microsoft with four complete network transport protocols (IP, IPX, AppleTalk and
NetBEUI) for use with NT when connected to a corporate network.

    The Windows NT server market continues to grow and outpace sales of other
popular non-NT-based servers. According to recent studies by International Data
Corporation and Dataquest, in 1997, Windows NT server shipments exceeded
shipments of any other server.

    Network Security

    Although open computing environments have many business advantages, their
accessibility makes an organization's critical software applications and
electronically stored data vulnerable to security threats. Open computing
environments are inherently complex, typically involving a variety of hardware,
operating systems, network transport protocols and applications supplied by a
multitude of vendors, making these networks difficult to manage, monitor and
protect from unauthorized access or attack. The security risk associated with
network computing is complicated by the increasing popularity of the Internet,
intranets and extranets (intranets which allow access for one or more users
outside of the internal network). By connecting an internal private network to
the Internet, unauthorized third parties are given a new means by which to
access an organization's private network. The combination of TCP/IP with other
commonly used network transport protocols within internal networks, increases
the network security challenge because of the various avenues of attack
available to both internal and external attackers.

    As a result of the explosive growth in network computing and Internet use
(as well as use of intranets and extranets), protection of an organization's
network and data has become a significant economic concern for businesses.
According to the 1997 Annual Information Week/Ernst & Young LLP Information
Security Survey of information technology managers and professionals, 42% of the
respondents reported malicious acts from external sources, as compared to 16% in
the prior year, and 43% of the respondents reported malicious acts by employees
as compared to 29% in the prior year. According to FBI estimates, U.S. companies
suffer estimated losses of $5 to $10 billion per year as a result of
unauthorized access to information and data. According to the 1998 CSI/FBI
Computer Crime and Security Survey, 44% of the respondents reported unauthorized
access by employees. The Company believes that securely segmenting internal
network areas and computing resources from unauthorized access will become
paramount to insuring the integrity of both the internal network and an
organization's intranet and extranet resources.


                                       34



    Firewalls

    A firewall is a security solution that enables an organization to protect
its computer resources from unauthorized access by internal and external users.
Firewalls enforce security access control policies between a trusted network and
an untrusted network. Only authorized traffic as defined by security policies is
allowed access through the firewall. Firewalls are predominantly utilized today
to provide security for a network's perimeter by preventing external breaches of
the internal network (trusted network) from untrusted external sources (the
public network).

    Due to the significant growth in Internet connections, a number of companies
have introduced firewall products ("IP Firewalls") designed primarily to protect
an internal network using TCP/IP as the network transport protocol from Internet
based security threats or threats from within Intranets. IP Firewalls can also
filter other network transport protocols used specifically with the IP routing
protocol (such as UDP and ICMP). In addition, a limited number of IP Firewalls
have limited filtering capabilities for a small number of non-IP based network
transport protocols.

    Firewalls can also serve to provide access control between individual
subnetworks on an internal network or to control access between an internal
network and a selected outside party authorized to have access to the internal
network for limited purposes. IP Firewalls can accomplish this task to the
extent that TCP/IP is the network transport protocol being used within an
internal network as is the case with intranets and extranets. To the extent
other network transport protocols are utilized within such an internal network,
IP Firewalls will disallow all data utilizing any such transport protocol from
passing through the firewall, thereby denying access entirely to a party which
is intended to have such access. This reduces the effectiveness of IP Firewalls
in a multi-protocol networked environment.

    The Company's FireWall/Plus family of security solutions is designed, like
other IP Firewalls, to protect against IP based Internet and intranet security
threats but also addresses security needs that arise from within internal
networks utilizing network transport protocols other than IP, including,
Novell's IPX, Digital Equipment Corporation's DECnet and IBM's SNA. The
Company's FireWall/Plus suite of products consists of a firewall designed to
control access to an organization's internal network from the public networks
(the "Enterprise Version"), a firewall controlling access between the network
and a trusted application server (the "Server Version") and a firewall
controlling access between the network and a trusted client workstation (the
"Desktop Version").

    The IP Firewall market is expected to continue to experience dramatic
growth. International Data Corporation estimates that 1996 unit shipments of
firewalls grew by more than 250%, compared with 1995, with 1996 revenues of
approximately $220 million. Unit sales of firewalls are expected to increase
from 36,610 units or approximately $220 million in 1996 to 1.1 million units or
$730 million in 2001. It is anticipated that unit prices of firewalls will
experience a decline in the future because of increased competition. The Company
believes that these projections do not take into account the need for firewalls
to protect computing environments that do not rely exclusively on TCP/IP as the
network transport protocol. While an organization generally requires a small
number of firewalls to restrict vulnerability to TCP/IP-based threats from the
Internet, it may require numerous firewalls to protect internal networks from
attacks from within the organization.



                                       35



    The Company believes that securely segmenting internal network areas and
computing resources from unauthorized access will become paramount to insuring
the integrity of both the internal network and an organization's intranet and
extranet resources. The Company further believes that multiple network transport
protocols will remain prevalent in computing environments because of the large
installed base of non-IP based computer systems and applications. The
FireWall/Plus security solution is positioned to address the security issues
faced by enterprises with multi-protocol networking environments seeking to
prevent unauthorized access and attacks from the Internet, intranets and
extranets and internal networks using network transport protocols other than
TCP/IP.

Network-1 Strategy

    The Company intends to pursue an aggressive growth strategy and to focus its
efforts on marketing its FireWall/Plus family of network security products. Key
elements of the Company's strategy are:

    -    Provide Comprehensive Network Security Solutions. The Company's
         strategy is to develop, market and support a family of network security
         products to address a broad range of security issues confronting
         computer networks and computing, including concerns arising from
         allowing access to the Internet as well as concerns relating to the
         security of internal networks. The Company's comprehensive approach to
         network security is based on its FireWall/Plus technology, which offers
         robust security for data communications utilizing TCP/IP as well as
         other network transport protocols. The FireWall/Plus family of firewall
         products currently includes the FireWall/Plus Enterprise Version,
         FireWall/Plus Server Version and the FireWall/Plus Desktop Solution.

    -    Emphasis on Internal Network Security. While FireWall/Plus has the
         ability to protect an organization's computer network from Internet,
         intranet and extranet based security threats, the Company believes that
         its ability to filter multiple network transport protocols offers
         significant advantages as a security product for internal networks
         where multiple protocols are common. Accordingly, the Company will seek
         to exploit this advantage by focusing significant marketing resources
         on the internal network security market. The Company intends to devote
         a significant portion of the proceeds of this offering for sales and
         marketing toward educating potential end users and third-party
         distributors as to the need to protect networks and computing resources
         from unauthorized access and attacks from within an internal network
         and the capabilities and benefits of the Company's products.

    -    Establish and Maintain Successful Third Party Distribution
         Relationships. The Company's marketing plan includes a multi-channel
         distribution strategy which emphasizes establishing and maintaining
         third-party distributor relationships with systems integrators, VARs,
         OEMs and resellers in the United States and internationally. The
         Company intends to increase its internal sales and support organization
         following the consummation of this offering primarily to provide
         additional support to its third-party distributors.



                                       36




    -    Leverage Consulting Clients. The Company has designed, planned,
         audited and implemented numerous networks worldwide for a broad
         spectrum of clients, including Fortune 500 companies, small companies
         with modest requirements, federal, state and foreign governments and
         utilities, as well as education and research institutions. The Company
         believes that its consulting clients provide a base of potential
         customers for its products. In addition, the Company's consulting
         relationships may facilitate its development and enhancement of
         software products as the Company's consultants receive feedback and
         guidance directly from network administrators and other technical
         personnel regarding products and features needed in the marketplace.
         See "Business - Consulting."

FireWall/Plus Technology

    The Company's network security solutions are based upon its proprietary
FireWall/Plus technology which provides organizations with enterprise wide
security to protect against unauthorized access from the Internet as well as
security for internal sources of intrusion and breach. The following are key
aspects of the Company's FireWall/Plus solution:

    Enterprise-Wide Deployment. Unlike most other firewall solutions which focus
on an enterprise's connection to the Internet, the FireWall/Plus solution, as a
result of its unique architecture, may be used throughout the enterprise; at the
perimeter to control access to and from the Internet, between internal networks
and on application servers, including web servers, and desktop PCs to protect
data residing on such servers and PCs. While competing firewall solutions must
be installed on dedicated computers, FireWall/Plus can operate on a Windows NT
desktop computer or application server without interfering with the normal
operation of such desktop computer or server. As a result, the FireWall/Plus
security solution can be installed on existing strategic computing resources
within the enterprise without incurring the expense of additional computing
hardware.

    Multi-layer Security. The architecture of Windows NT includes two operating
modes, the "user" and "kernel" modes. The FireWall/Plus solution is implemented
in kernel mode to maximize performance and to provide maximum security from
network intrusion to the operating system environment. Using proprietary
kernel-level software code developed by the Company, FireWall/Plus's Interceptor
Shim and security filter engine technology introduce a security layer between
the network hardware drivers and the Windows NT operating system. FireWall/Plus
filters all network traffic before it reaches Windows NT. Incoming data packets
enter the network through the network interface card and its associated hardware
driver and are immediately passed to the Interceptor Shim, which directs them to
the FireWall/Plus filter engine. The filter engine, using a proprietary
high-speed, real-time security policy enforcement language, checks the packet
and associated packet history against the security rule policy database to
determine whether the packet should be allowed to enter the system. The Company
believes that FireWall/Plus' multi-layer approach to security strengthens
Windows NT by providing a layer of security that filters packets before entering
the Windows NT operating system.

    Advanced Filtering System. The Company's FireWall/Plus family of products
includes an advanced filtering system which currently utilizes stateful
inspection and application level filtering technology to provide security for
IP-related transport protocols and applications. Stateful filtering 



                                       37



involves the knowledge of states of protocols at specific transaction intervals
during the network connection between two communicating applications between
specific systems. Transaction states occur at routing, transport, session
control and application layers when two programs interoperate with each other
over a computer network connection. When these states are defined to
FireWall/Plus, FireWall/Plus can take actions on conditions that violate the
required or expected stateful actions of one or a simultaneous series of
protocols. Most firewalls have been based upon architectures incorporating
either packet filtering or proxy application gateway filtering. FireWall/Plus
adopts a hybrid approach which incorporates frame, circuit, packet, proxy
application and stateful inspection capabilities in the security management of
network connections. The Company believes that this hybrid approach allows the
Company to offer a firewall product that maximizes security without sacrificing
performance.

    Multi-Protocol Capability. A unique aspect of FireWall/Plus is its ability
to provide multi-protocol filtering not available from network security products
offered by other firewall vendors. FireWall/Plus has the advantage of filtering
not only TCP/IP, but also a multitude of other network transport protocols. The
Company believes that the ability of FireWall/Plus to filter multiple network
transport protocols offers significant advantages as a security product for
internal networks where multiple network transport protocols are common.
FireWall/Plus is capable of utilizing stateful inspection technology for
numerous network transport protocols once the various "states" of such protocols
are defined to FireWall/Plus. The states of TCP/IP and several other of the more
commonly used protocols are capable of being defined. For those protocols not
capable of being defined, FireWall/Plus performs frame, packet and application
filtering. In a Windows NT based environment, it is typical for all commonly
used multiple network transport protocols to co-exist, as Windows NT comes
pre-equipped with TCP/IP, IPX (Novell), NetBEUI (LAN Manager) and AppleTalk. In
addition, certain applications require the use of non-IP protocols to operate
between subnetworks on a network. FireWall/Plus' multi-protocol filtering
capability is also critical in the support of web servers on the Internet,
intranets and extranets and other information provision systems that access
information stored on mainframe computers via non-IP protocols. While some
commercially available routers allow basic packet filtering for multiple
protocols, the Company believes its multi-protocol advanced filtering
capabilities offer superior features to routing solutions such as a graphical
user interface, extensive logging, reporting and alarming and security policy
time management.

    Transparency. FireWall/Plus may be operated in a transparent mode. In this
mode, FireWall/Plus has no network address (i.e. it is not visible on the
network) and therefore can not be identified for attack. The Company believes
that this feature provides additional security to the operating system because
when a firewall has a network address, it can be located and is more susceptible
to attack. FireWall/Plus provides firewall protection while operating in
transparent mode, except that certain features such as remote management, proxy
support and virtual private networking are not functional.

    Centralized Management. FireWall/Plus allows for centralized management and
monitoring that allows a network manager to manage and monitor a system from a
local or remote location. Accordingly, large and geographically dispersed
firewalls may be managed from a single location.



                                       38




    Customized Security Policies. FireWall/Plus also allows customized security
policies for individual departments, applications and individual systems and
personnel within the network. Network managers may apply security rules to any
version of the FireWall/Plus products so that individual systems, protocols,
applications, frames and many other network entities are either explicitly
denied or authorized access to specific applications and other network entities.

    Multi-Protocol Encryption Tunnels. Once firewalls are in place at multiple
sites on a WAN or the Internet, the ability to establish encrypted
communications links over these connections becomes possible, thereby reducing
reliance on more costly dedicated telecommunications alternatives. FireWall/Plus
provides for integrated data encryption to protect communications over the
Internet and other public networks from unauthorized access. Encryption tunnels,
known as virtual private networks ("VPNs"), may be set up for any Windows NT
based protocol to protect communications between different locations of an
organization's internal network or between different locations and selected
customers, suppliers or strategic partners. FireWall/Plus extends this ability
such that VPNs may be formed between locations across the Internet irrespective
of the transport protocol being tunneled. The Company currently resells VPN
client solutions from Aventail Corporation in conjunction with FireWall/Plus.

    Proxy Support. Proxy based firewalls filter network traffic by running a
separate software program that acts as a proxy for each application to be
allowed through the firewall. These firewall solutions require the customer to
purchase the proxies supplied by the vendor for the applications supported by
the vendor's architectural model. As a result, the customer may not find all the
required application proxies from a specific firewall vendor for all the
application suites being used or may find that the proxies offered by the
firewall vendor are not sufficient to support all the required security needs.

    FireWall/Plus includes several popular proxies in addition to frame,
circuit, packet, application and stateful inspection capabilities. These proxies
implement popular features for specific application types such as HTTP and FTP.
The Company currently licenses HTTP and FTP proxies from Network Associates,
Inc. FireWall/Plus also allows the use of other third-party proxies in
conjunction with or in lieu of proxies offered by the Company. FireWall/Plus'
architecture allows the Company to partner and include external or third-party
proxies quickly and easily to suit a variety of security requirements.
Additionally, custom-written proxies for a client-server architecture at a
customer site may easily be added to the FireWall/Plus system by adjusting
security policy rule sets in the firewall database.

    Ease of Use. FireWall/Plus was designed to be easily installed, configured
and managed by a network manager with minimal or no security skills.
FireWall/Plus may be installed and configured by use of the intuitive graphical
user interface ("GUI") by simply pointing and clicking the mouse. To facilitate
implementation, FireWall/Plus comes pre-programmed with a wide variety of
frequently used default security policies which require the customer to simply
select one of the rule-bases and save the selection. FireWall/Plus does not
utilize significant server resources and may therefore co-exist on the same
server with other software applications on Windows NT. Unlike many other
competitive firewall products offered today, FireWall/Plus need not run on a
separate dedicated server.

Products

    The Company's family of FireWall/Plus products offers a broad range of
network security solutions. The FireWall/Plus family of products includes the
FireWall/Plus Enterprise Version, FireWall/Plus Server Version and FireWall/Plus
Desktop Version. The Company is currently shipping FireWall/Plus Version 4.03.
The Company first introduced the FireWall/Plus Enterprise Version for Windows NT
in January 1997. As of June 30, 1998, the Company had licensed one or more of
its FireWall/Plus family of software products to over 150 customers. License
revenue from FireWall/Plus products accounted for 43%, 60% and 58% of the
Company's revenues for the years ended December 31, 1996, 1997 and the three
months ended March 31, 1998, respectively, reflecting the Company's emphasis on
the development and marketing of software products rather than consulting
services.

    FireWall/Plus Enterprise Version. The FireWall/Plus Enterprise Version
secures an organization's internal network against unwarranted intrusions from
the Internet and is also used between major internal network components as well
as between general access internal networks and special purpose networks such as
process control, real-time and other sensitive access networks. The
FireWall/Plus Enterprise Version includes extensive centralized and remote
security management facilities, predefined security policy rules, multiprotocol
VPN capabilities, authentication and encryption facilities, real time connection
management and proxy services. The FireWall/Plus Enterprise Version supports
Intel processors and Digital Equipment Corporation Alpha processors that support
Windows NT. The FireWall/Plus Enterprise Version is available in scaleable
models to support varying numbers of simultaneous connections for small to
mid-size companies and in an unlimited session version, as well as a high-speed
version. Additionally, the FireWall/Plus Enterprise Version is also available in
a Premier Version which includes the software installed on a high speed Alpha
server running Windows NT. Based on the number of concurrent connections, the
nature of the user's operating system and whether hardware is needed, the
FireWall/Plus Enterprise Version is currently priced to end users between $3,750
and $20,000 for software only versions and from $27,500 to $30,000 for Premier
Versions, which include hardware and onsite technical support.

    FireWall/Plus Server Solution. The FireWall/Plus Server Version is designed
to improve internal security of a LAN or Intranet or to protect highly sensitive
systems such as key escrow facilities, web servers, digital certificate servers,
database servers, authentication servers, etc. As a server firewall, this
solution provides protection against unauthorized access to network resources by
internal users, where security breaches often originate. The FireWall/Plus
Server Version co-exists on the server being protected and resides between the
network users and the protected data. FireWall/Plus Server Version treats all
information on the server as secure and guarded, while treating network
connections to the server as unsecure. FireWall/Plus can then be configured
using the FireWall/Plus GUI to allow access to certain users, to specific
applications, during designated times and under a variety of conditions. The
FireWall/Plus Server Version incorporates all of the major features contained in
the FireWall/Plus Enterprise Version. Any other applications including web, file
and print services, may be run simultaneously on the server with the
FireWall/Plus Server Version installed and operating. The FireWall/Plus Server
Version is currently priced to end users at $1,995.



                                       40




    FireWall/Plus Desktop Solution. The FireWall/Plus Desktop Version is a full
featured firewall which has been specifically tailored to protect data residing
on Windows NT workstations without disrupting current system operations. These
workstations can run applications while the firewall maintains a high level of
security. When a network attack is detected, it is immediately defeated prior to
the attack being able to access the NT Workstation. The FireWall/Plus Desktop
Version is designed to protect sensitive individual desktop computers (such as a
network control station, a corporate executive's personal computer or the human
resources personnel system) or telecommuter systems where high speed remote
access lines are used (such as cable modems, ADSL and ISDN). The FireWall/Plus
Desktop Version is currently priced to end users at $995.

Customers

    The Company's customers represent a wide range of industries, both
commercial and government, which consider networked-data resources to be among
the most important assets within their organizations. As of June 30, 1998, the
Company had licensed one or more of its FireWall/Plus family of products to over
150 customers. Customers for the FireWall/Plus products include The Sabre Group
Inc., Electronic Data Systems Corporation ("EDS"), Trusted Information Systems,
Inc., TRW, Inc., United Technologies, Inc., National Semiconductor Corp.,
Fairchild Semiconductor, ARCO, GTE, Inc., and Continental Airlines. During the
year ended December 31, 1997, Trusted Information Systems, Inc. and EDS
accounted for approximately 21% and 14% of the Company's revenues, respectively.

    Examples of the varied uses of the Company's products by customers include:

    /  / An industry leading system integrator uses both the Enterprise and 
Server Versions of FireWall/Plus to secure access and communications to and 
from its facilities management personnel and their customers to manage the 
networks of one of the largest telecommunications companies. The 
FireWall/Plus Enterprise Versions are used as perimeter defenses on the 
company's internal backbone, which supports more than 900 outside clients, 
while the FireWall/Plus Server Versions are used to protect key internal 
components on the customer's internal network.

    /  / A leading travel service company utilizes FireWall/Plus' high speed 
Premier Versions to protect one of the busiest websites on the Internet. 
Multiple firewalls are also being used internally to securely filter DECnet, 
which is the prevalent network transport protocol used in addition to TCP/IP, 
between various segments of the internal network. Additionally, this customer 
has begun to install multiple FireWall/Plus versions at its customers' sites.

    /  / A worldwide petrochemical company currently uses FireWall/Plus 
Enterprise Version to secure data at multiple sites from internal and 
external breaches. Disparate protocols, including IP and Novell's IPX, are 
securely and routinely sent from multiple data centers (each using 
FireWall/Plus) throughout the country to a center of operations while 
FireWall/Plus insures the integrity of the data.

                                       41




    The Company believes that the FireWall/Plus security solution is a scaleable
product which satisfies customers' needs to secure the perimeter and internal
resources within their organizations. The Company further believes that
currently available IP Firewalls are not as flexible with respect to both
internal and external security as the FireWall/Plus solution.

    During the years ended December 31, 1996 and 1997 and the three months ended
March 31, 1998, license revenue from international customers (licenses to
foreign end users and international distributors) accounted for 6.7%, 15.6% and
2.7% of the Company's revenues, respectively. All of the Company's revenues from
international licenses were denominated in U.S. dollars. The Company anticipates
that revenues from international customers will account for an increasing
percentage of the Company's revenues in the future.

Sales and Marketing

    The Company is in the process of implementing a sales and marketing plan
which consists of a multi-channel distribution strategy and a promotion strategy
to create consumer awareness of the Company and its FireWall/Plus products and
to educate the market about the need to implement network security products and
of the capabilities and benefits of the Company's FireWall/Plus products.

    Multi-Channel Distribution

    In-House Sales Force. The Company's internal sales force consists of three
persons, consisting of a Vice President of Sales of North America and two sales
representatives. The Company's sales representatives are responsible for
soliciting potential customers and providing technical support to customers, as
well as supporting third-party distribution channels. To date, the Company's
internal sales force has not undertaken significant marketing efforts relating
to product commercialization.

    Following the consummation of this offering, the Company intends to retain a
Vice-President of International Sales to oversee the Company's international
sales and marketing efforts and a limited number of additional sales
representatives in connection with the expansion of the Company's marketing
efforts. Although the Company's in-house sales force will continue to solicit
potential customers, its primary responsibility is expected to be supporting
third-party distribution channels.

    Third-Party Distribution Channels. A key element of the Company's
distribution strategy is to establish and maintain relationships with
third-party distributors within the United States and internationally. By
engaging such third-party distributors, the Company is able to utilize the
end-user sales and support infrastructure of these channels.

    The Company currently has relationships with 22 national, regional and local
systems integrators, VARs and resellers in the United States, including EDS,
Wang Laboratories, Inc. and BDM International, Inc. In November 1997, the
Company entered into a Master Software License Agreement with EDS pursuant to
which EDS has the non-exclusive right on a worldwide basis to use, market and
distribute the Company's Fire Wall/Plus family of products including the right
to promote and resell such products in conjunction with providing systems
integration, outsourcing or facilities 



                                       42




management services to its customers. The Company also currently has
relationships with international system integrators, VARs, resellers and
distributors in 25 countries, including Japan, Germany, Canada, United Kingdom,
Republic of China, Hong Kong, Russia, Taiwan, Korea, Singapore, Malaysia,
Indonesia, Thailand and Turkey.

    The Company's agreements with distributors generally grant the distributor
the right to market the Company's products in specified territories on a
non-exclusive basis, are terminable on short notice and do not prohibit the
distributor from selling products that are competitive with the Company's
products.

    The Company intends to continue to seek to establish relationships with
additional third-party distributors, principally larger system integrators and
VARs with the necessary resources to successfully distribute the Company's Fire
Wall/Plus products. For the year ended December 31, 1997, Trusted Information
Systems, Inc. ("TIS") and EDS accounted for 21% and 14%, respectively, of the
Company's revenues and for the three months ended March 31, 1998, The Sabre
Group, Inc. and Omnicon Systems, Inc. accounted for 24% and 13%, respectively,
of the Company's revenues. The Company's five largest distributors accounted for
an aggregate of approximately 28% and 40% of the Company's revenues for the year
ended December 31, 1997 and the three months ended March 31, 1998, respectively.

    The Company also seeks to enter OEM or licensing arrangements whereby the
Company grants to an OEM or other third party the right to incorporate and/or
bundle a specific technology of the Company with the OEM's or other
third-party's products. In June 1997, the Company entered into a license
agreement with TIS, which was subsequently acquired by Network Associates, Inc.,
pursuant to which the Company licensed to TIS which was on a non-exclusive basis
the right to incorporate and/or bundle the Company's Interceptor Shim software
with TIS' family of Gauntlet(TM) firewall products. The Company receives a
royalty based upon TIS sales, of which $500,000 was paid to the Company as a
non-refundable pre-paid royalty. As a result of such pre-paid royalty, license
revenue from TIS accounted for 21% of the Company's revenues for the year ended
December 31, l997.

    The Company expects that its arrangements with third-party distributors and
OEMs will account for an increased percentage of its product sales in the
future.

    Advertising and Promotion

    Following the consummation of the offering, the Company intends to implement
an advertising and promotion strategy to create consumer awareness of the
Company and its FireWall/Plus products and to educate the market about network
security threats and FireWall/Plus's ability to address customers' needs. To
date, the Company has engaged in limited advertising and promotion of its
products through its website, trade publication and published product reviews.
The Company intends to use a portion of the proceeds of this offering to
advertise and promote its products through print advertising, Internet website
advertising, direct marketing efforts and participation in trade shows and
seminars which target organization security and management information system
administrators and network system integrators.



                                       43


     The Company's website, www.network-1.com, which includes a description of
the Company's FireWall/Plus family of products and enables visitors to the site
to download a 50-session FireWall/Plus Enterprise Version for a 30-day trial.
The Company intends to use a portion of the proceeds of this offering to add
content to the website, such as product information, including a user guide,
network security industry information and additional content specific to
distributors and end users; improve download capabilities for the trial version;
and enable purchases via the website.

Consulting

     The Company has designed, planned, audited and implemented numerous
networks worldwide for a broad spectrum of clients, including Fortune 500
companies, small companies with modest requirements, federal, state and foreign
governments and utilities, as well as education and research institutions. Mr.
William Hancock, the Company's Chief Technology Officer and a director, is an
industry expert who has authored networking and security books and has been a
featured columnist as well as a network and security editor for a number of
industry journals. The Company intends to expand its consulting activities
following the consummation of this offering by utilizing the expertise of Mr.
Hancock to create opportunities for consulting through speaking engagements at
industry conferences, seminars and trade shows.

     Historically, the Company has offered a wide range of consulting services
designed to provide solutions to networking and security problems. Such
consulting services have included network surveys, network designs and traffic
modeling, security penetration studies, security breach investigation, network
and computer forensics services, hacker prosecutions (in connection with federal
and local law enforcement agencies) and network security technical audits among
other services. The Company generally provides its consulting clients with a
comprehensive report containing detailed findings and recommendations. The
Company offers its consulting services on a per hour or per project basis.

     The Company's consulting clients have included, among others, EDS, MCI
Communications Corp., Kraft General Foods, Inc., Alcoa Aluminum Company of
America, TIA-CREF, Southwestern Bell Telephone Co., Chemical Bank Corp., Hewlett
Packard Co., American Airlines, Inc., Bechtel Corporation, ARINC, ARCO Chemical
Company, United Technologies Sikorsky Aircraft, Bowne, Inc., and the U.S.
Government, including The Environmental Protection Agency.

     Consulting services generated 24%, 21% and 27% of the Company's revenues
for the years ended 1996 and 1997 and the three months ended March 31, 1998,
respectively. The Company expects that consulting services will account for a
decreasing percentage of revenue as the Company continues to focus its efforts
on developing and marketing its network security software products.

Customer Service and Support

     The Company believes that customer service and support is critical to
retaining customers and attracting prospective customers. The Company provides
customer service and support through its internal technical support staff of 5
persons located at its Grand Prairie, Texas office. Customers receive a 90-day
warranty, which includes technical assistance and product updates. To date, the
Company has not incurred any material warranty expense. Following the expiration
of the 90-day warranty, customers can elect to purchase the Company's annual
maintenance program at an average 

                                       44


annual cost of 15% of the then current purchase price. The maintenance program
includes technical assistance and support, product updates and general
information relating to product introductions and changes. Technical support is
available 24 hours a day, 7 days a week, by telephone and electronic mail. In
addition, the Company provides customers with fee-based on-site installation,
support and training. The Company provides its resellers with sales and
technical support.

Product Development

     The Company believes that development of new products and enhancements to
existing products are essential for the Company to effectively compete in the
network security market. The Company's product development efforts are directed
toward enhancing its FireWall/Plus family of security products, developing new
products and responding to emerging industry standards and other technological
changes. The Company intends to expand its existing product offerings and to
introduce new application products for the network security market. The
Company's new product development efforts are focused on enhancements to the
Company's current suite of products and new network security products, including
products that support Windows 95/98 operating systems. While the Company expects
that certain of its new products will be developed internally, the Company may,
based on timing and cost considerations, expand its product offerings through
acquisitions. In addition, the Company has relied and will continue to rely on
external development resources for the development of certain of its products
and components.

     The Company currently has 10 employees devoted to research and product
development. However, historically, a substantial portion of the Company's
research and development activities have been undertaken by engaging third-party
consultants and independent contractors. During the years ended December 31,
1996 and 1997 and three months ended March 31, 1998, the Company's product
development expenses were $984,000, $917,000 and $208,000, respectively.

     The Company intends to hire and retain approximately 17 additional software
engineers and developers on a full-time basis within twelve months following the
consummation of this offering and has allocated approximately $2,100,000 of the
net proceeds of this offering to software development.

     The network security industry is characterized by rapid technological
change, changes in customer requirements, frequent new product introductions and
enhancements, new and continuously evolving network security threats and attack
methodologies and evolving industry standards in computer hardware and software
technology. As a result, the Company must continually change and improve its
products in response to such advances and changes in operating systems,
application software, computer and communications hardware, networking software,
programming tools and computer language technology. The introduction of products
embodying new technologies and the emergence of new industry standards may
render existing products obsolete or unmarketable.

         The Company's future operating results will depend upon the Company's
ability to enhance its current products and to develop and introduce new
products on a timely basis that address the increasingly sophisticated needs of
the marketplace and that keep pace with technological developments, new
competitive product offerings and emerging industry standards. There can be no
assurance that the Company will be successful in developing and marketing new
products or product enhancements that respond to technological change and
evolving industry standards and customer requirements, that the Company will not
experience difficulties that could delay or prevent the 

                                       45


successful development, introduction and marketing of these products, or that
any new products and product enhancements will adequately meet the requirements
of the marketplace and achieve market acceptance. In the event that the Company
does not respond adequately to the need to develop and introduce new products or
enhancements of existing products in a timely manner in response to changing
market conditions or customer requirements, the Company's business, operating
results and financial condition will be materially adversely affected.

Competition

     The network security market in general, and the firewall product market in
particular, is characterized by intense competition and rapidly changing
business conditions, customer requirements and technologies. The Company
believes that the principal competitive factors affecting the market for network
security products include security effectiveness, name recognition, scope of
product offerings, product features, distribution channels, price, ease of use
and customer service and support. Currently, the Company's principal competitors
include AXENT Technologies Inc., Bay Networks, Inc., CheckPoint Software
Technologies, Ltd., Cisco Systems, Inc., Compaq Computer Corporation, Cyberguard
Corp., International Business Machines Corporation, ISS Group, Inc., Microsoft
Corporation, Network Associates, Inc. and Secure Computing Corporation. Due to
the rapid expansion of the network security market, the Company may face
competition from new entrants.

     Most of the Company's current and potential competitors have longer
operating histories, greater name recognition, larger installed customer bases
and possess substantially greater financial, technical and marketing and other
competitive resources than the Company. As a result, the Company's competitors
may be able to adapt more quickly to new or emerging technologies and changes in
customer requirements or devote greater resources to the promotion and sale of
their products than the Company. While the Company believes that its firewall
products do not compete against manufacturers of other types of security
products (such as encryption and authentication products), there can be no
assurance that potential customers will not perceive the products of such other
companies as substitutes for the Company's products. In addition, certain of the
Company's competitors may determine for strategic reasons to consolidate, to
substantially lower the price of their network security products or to bundle
their products with other products, such as hardware or other enterprise
software products. Accordingly, it is possible that new competitors and
alliances among competitors may emerge and rapidly acquire significant market
share. There can be no assurance that the Company's current and potential
competitors will not develop products that may be more effective than the
Company's current or future products or that the Company's products would not be
rendered obsolete or less marketable by evolving technologies or changing
consumer demands or that the Company will otherwise be able to compete
successfully. Increased competition for firewall products may result in price
reductions, reduced gross margins and adversely effect the Company's ability to
gain market share, any of which would adversely affect the Company's business,
operating results and financial condition.


                                       46


Proprietary Rights

     The Company's success is substantially dependent on its proprietary
technologies. The Company does not hold any patents and relies on copyright and
trade secret laws, non-disclosure agreements with employees, distributors and
customers, including "shrink wrap" license agreements that are not signed by the
customer, and technical measures to protect the ideas, concepts and
documentation of its proprietary technologies and know-how to protect its
intellectual property rights. Such methods may not afford complete protection,
and there can be no assurance that third parties will not independently develop
substantially equivalent or superior technologies or obtain access to the
Company's technologies, ideas, concepts and documentation. In addition, there
can be no assurance that any confidentiality agreements between the Company and
its employees, distributors or customers will provide meaningful protection for
the Company's proprietary information in the event of any unauthorized use or
disclosure. Any inability to protect its proprietary technologies could have a
material adverse effect on the Company. Furthermore, the Company may be subject
to additional risk as it enters into transactions in countries where
intellectual property laws are not well developed or are poorly enforced. Legal
protection of the Company's rights may be ineffective in such countries.

     The Company also licenses from a third party certain proxy technology which
is incorporated into its FireWall/Plus products. The Company is dependent in
part on its ability to continue to license such technology. Any inability of the
Company to be able to continue to utilize such technology either as a result of
the Company's breach or the termination of a license agreement or otherwise, in
the absence of similar available technologies, could have a material adverse
effect on the Company.

     The Company received a U.S. trademark registration for the FireWall/Plus
name in December 1996. Although the Company is not aware of any challenges to
the Company's rights to use this trademark, there can be no assurance that the
use of this mark would be upheld if challenged.

     Although the Company believes that its technologies and products have been
developed independently and do not infringe upon the proprietary rights of
others, there can be no assurance that the Company's technologies and products
do not and will not so infringe or that third parties will not assert
infringement claims against the Company in the future. The Company is not aware
of any patent infringement charge or any violation of other proprietary rights
claimed by any third party relating to the Company or the Company's products. In
response to certain public statements made by CheckPoint Software Technologies,
Ltd. related to a patented technology referred to as "stateful inspection" (the
"Checkpoint Patent"), the Company retained patent counsel in April 1997 to
review the Checkpoint Patent as compared to the Company's intellectual property
and associated products. Based upon the opinion of the Company's intellectual
property counsel, the Company does not believe that the CheckPoint Patent will
have a material adverse effect on the Company. If, however, the Company's
technologies or products were deemed to infringe upon the Checkpoint Patent, or
if the Company's technologies or products were deemed to infringe upon the
proprietary rights of other third parties, the Company could become liable for
damages or be required to modify its products or to obtain a license.

                                       47



     As the number of security products being offered continue to increase the
functionality of such products may further overlap, which could result in
increased infringement claims by software developers, including infringement
claims against the Company with respect to future products. There can be no
assurance that the Company would be able to modify its products or obtain a
license in a timely manner, upon acceptable terms and conditions, or at all, or
that the Company will have the financial or other resources necessary to defend
a patent infringement or other proprietary rights infringement action. Failure
to do any of the foregoing could have a material adverse effect on the Company,
including possibly requiring the Company to cease marketing its products.

CommHome Systems Corp. Acquisition

     Prior to the consummation of this offering, the Company will enter into a
merger agreement with CommHome Systems Corp. ("CommHome"), effective upon
consummation of this offering, pursuant to which the CommHome stockholders have
agreed to exchange all of the outstanding common stock of CommHome for 35,000
shares of Common Stock of the Company. Pursuant to the merger agreement, the
Company has agreed to assume up to $200,000 of liabilities of CommHome, which
include $55,000 and $50,000 owed to Avi A. Fogel and Robert P. Olsen,
respectively. Messrs. Fogel and Olsen have agreed to accept 6,875 and 6,250
shares of Common Stock, respectively, in full satisfaction of such indebtedness.
Mr. Fogel, President, Chief Executive Officer and a director of the Company, is
also President, Chief Executive Officer and owns 51% of the outstanding shares
of CommHome. Mr. Olsen, Vice President of Product Management of the Company, is
the former Vice President of Marketing of CommHome. See "Certain Transactions."

     CommHome, incorporated in June 1997, is a development stage company engaged
in the design and development of residential networking solutions for high speed
Internet access to the home. CommHome's designs are intended to provide easy
access to the Internet throughout the home. These solutions include secure
connections to high speed networking technologies, such as ADSL and cable modem
technology, and easy distribution at all phone connections. It is currently
expected that CommHome's designs will be incorporated into the Company's future
security products.

Employees

     As of June 30, 1998, the Company had 22 full time employees, including 5 in
sales and marketing, 10 in product research and development and technological
support and 7 in administration and finance. None of the Company's employees is
represented by a labor union or is subject to a collective bargaining agreement.
The Company has not experienced any work stoppages and considers its
relationship with its employees to be good.

     Competition with respect to the recruiting of highly qualified personnel in
the software industry is intense and many of the Company's competitors have
significantly greater resources than the Company. The Company's ability to
attract and assimilate new personnel will be critical to the Company's
performance and there can be no assurance that the Company will be successful in
attracting or retaining the personnel it requires to enhance its products,
develop new products and conduct its operations successfully.

                                       48

establish an Audit Committee and a Compensation Committee. The Audit Committee
will review the qualifications of the Company's independent auditors, make
recommendations to the Board of Directors regarding the selection of independent
auditors, review the scope, fees and results of any audit, and review non-audit

Stock Option Plan

     On March 7, 1996, the Board of Directors and stockholders of the Company
approved the adoption of the Stock Option Plan. The Stock Option Plan, as
amended, is intended to assist the Company in securing and retaining key
employees, directors and consultants by allowing them to participate in the
ownership and growth of the Company through the grant of incentive and
non-qualified options (collectively, the "Options"). Under the Stock Option
Plan, key employees (including officers and employee directors) are eligible to
receive grants of incentive stock options. Employees (including officers),
directors of the Company or any affiliates and consultants are eligible to
receive grants of non-qualified options. Incentive stock options granted under
the Stock Option Plan are intended to be "Incentive Stock Options" as defined by
Section 422 of the Internal Revenue Code of 1986, as amended.

     The Stock Option Plan has been administered by the Board of Directors and
following the consummation of this offering will be administered by the
Compensation Committee of the Board of Directors of the Company. The
Compensation Committee of the Board of Directors will consist of members who
have been determined by the Board of Directors to be "disinterested persons"
within the meaning of Rule 16b-3(c)(2)(i) promulgated under the Exchange Act or
any future corresponding rule.

     The Compensation Committee will determine who shall receive Options, the
number of shares of Common Stock that may be purchased under the Options, the
time and manner of exercise of Options and exercise prices. The term of Options
granted under the Stock Option Plan may not exceed 10 years (five years in the
case of an incentive stock option granted to an optionee owning more than 10% of
the voting stock of the Company) (a "10% Holder"). The exercise price for
incentive stock options shall not be less than 100% of the "fair market value"
of the shares of Common Stock at the time the Option is granted; provided,
however, that with respect to an incentive stock option, in the case of a 10%
Holder, the purchase price per share shall be at least 110% of such fair market
value. The exercise price for non-qualified options is set by the Compensation
Committee in its discretion. The aggregate fair market value of the shares of
Common Stock as to which an optionee may exercise incentive stock options may
not exceed $100,000 in any calendar year. Payment for shares purchased upon
exercise of Options is to be made in cash, check or other instrument, and at the
discretion of the Committee, may be made by delivery of other shares of Common
Stock of the Company. If any Option granted under the Plan expires or terminates
for any reason without having been exercised in full, then the unpurchased
shares subject to the Option will once again be available for additional Option
grants.

     Under certain circumstances involving a change in the number of
outstanding shares of Common Stock including a stock split, consolidation,
merger or payment of stock dividend, the class and aggregate number of shares of
Common Stock in respect of which Options may be granted under the Stock Option
Plan, the class and number of shares subject to each outstanding Option and the
exercise price per share will be proportionately adjusted.

                                       57


     An aggregate of 750,000 shares of Common Stock has been reserved for
issuance upon exercise of the Options to be granted under the Stock Option Plan.
As of the date of this Prospectus, the Company has granted Options to purchase
423,908 shares of Common Stock under the Plan, of which Options to purchase
58,976, 58,500, 62,080, 62,500 and 20,000 shares of Common Stock have been
granted to Messrs. Olsen, Fish, Mearsheimer, Donohue, and Ranum, respectively.
The Options granted to Messrs. Olsen and Fish are exercisable at a price of
$5.60 per share, the Options granted to Mr. Mearsheimer are exercisable at
prices ranging from $4.83 to $6.44 per share, and the Options granted to Messrs.
Donohue and Ranum are exercisable at a price of $7.20 per share.

401(k) Plan

     The Company maintains the Network-1 Savings and Investment Plan, a defined
contribution pension plan with a cash or deferred arrangement as described in
Section 401(k) of the Internal Revenue Code of 1986, as amended (the "401(k)
Plan"). The 401(k) Plan is intended to qualify under Section 401(a) of the Code,
so that contributions, and income earned thereon, are not taxable to employees
until withdrawn. All regular full-time Company employees over the age of 21 are
eligible to participate in the 401(k) Plan. The 401(k) Plan provides that each
participant may make elective pre-tax salary deferrals up to 15% of his or her
annual compensation, subject to statutory limits. The Company also may make
discretionary annual matching contributions in amounts determined by the
Compensation Committee of the Board of Directors, subject to statutory limits.
The Company's policy is to base its contributions on Company profitability. The
Trustee of the 401(k) Plan invests each employee's account at the direction of
the employee, who may choose among several investment alternatives, which do not
include shares of the Company's Common Stock. The Company did not make any
contributions to the 401(k) Plan during 1997.

Limitation on Liability and Indemnification Matters

     The Company's Certificate of Incorporation limits the liability of
directors to the maximum extent permitted by Delaware law. Delaware law provides
that directors of a corporation will not be personally liable for monetary
damages for breach of their fiduciary duties as directors, except for liability
(i) for any breach of their duty of loyalty to the corporation or its
stockholders, (ii) for acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law, (iii) for unlawful
payments of dividends or unlawful stock repurchases or redemptions as provided
in Section 174 of the Delaware General Corporation Law or (iv) for any
transaction from which the director derived an improper personal benefit.

     The Company's Bylaws provide that the Company'shall indemnify its
directors, officers, employees and agents to the fullest extent permitted by
law. The Company's Bylaws also permit the Company to secure insurance on behalf
of any officer, director, employee or other agent for any liability arising out
of his or her actions in such capacity, regardless of whether the Bylaws would
permit indemnification. The Company currently maintains liability insurance for
its officers and directors.

     At present, there is no pending material litigation or proceeding involving
any director, officer, employee or agent of the Company where indemnification
will be required or permitted. The Company is not aware of any threatened
litigation or proceeding that might result in a material claim for such
indemnification.

                              CERTAIN TRANSACTIONS

     In February and April 1997, the Company issued an aggregate principal
amount of $1,000,000 of notes bearing interest at the rate of 6% per annum, and
warrants to purchase an aggregate of 139,679 shares of the Company's Common
Stock at an exercise price of $6.44 per share in private financings (the
"February and April 1997 Private Financings"). The principal amount of the notes
issued in connection with the February and April 1997 Private Financings, plus
accrued interest thereon, will be repaid from the proceeds of this offering. In
connection with the February and April 1997 Private Financings, the Company
issued a note in the principal amount of $250,000 and warrants to purchase
34,920 shares of Common Stock to Applewood Associates, L.P. ("Applewood"), a
principal stockholder of the Company, and a note in the principal amount of
$50,000 and warrants to purchase 6,984 shares of Common Stock to Herb Karlitz.
Barry Rubenstein, a principal stockholder of the Company, is a general partner
of Applewood. Herb Karlitz is the brother-in-law of Corey M. Horowitz, Chairman
of the Board of Directors and a principal stockholder of the Company. In
connection with the February and April 1997 Private Financings, Robert Russo,
Vice President of Business Development and Secretary of the Company, delivered
to the Company for cancellation 39,110 shares of Common Stock in consideration
of $630, and William H. Hancock, Chief Technology Officer and a director of the
Company, delivered to the Company for cancellation 54,009 shares of Common Stock
in consideration of $870.

     On August 30, 1996 the Company entered into an agreement (the "CMH Advisory
Agreement"), as amended, with CMH Capital Management Corp. ("CMH"), a
corporation wholly-owned by Corey M. Horowitz, Chairman of the Board of
Directors and a principal stockholder of the Company, pursuant to which CMH
agreed to render advisory services to the Company in consideration of fees of
$12,500 per month for a period of two years and the issuance of warrants to
purchase 31,040 shares of the Company's Common Stock at an exercise price of
$8.05 per share and 31,040 shares of the Company's Common Stock at an exercise
price of $6.44 per share (collectively, the "CMH Advisory Warrants"). In
addition, the Company agreed that in the event it completes a merger or sale of
substantially all of its assets prior to January 15, 1999, CMH would be entitled
to a cash fee equal to 2% of the value of the total consideration received in
connection with such transaction. CMH agreed that the monthly fee of $12,500
would accrue until the Company completed a financing of a minimum of $5,000,000.
On May 14, 1998, CMH agreed with the Company to convert accrued fees of $200,000
into 31,250 shares of Common Stock of the Company in full satisfaction of
Company's fee obligation to CMH under the CMH Advisory Agreement.

     On August 8, 1997, CMH loaned the Company $100,000 at an interest rate of
8% per annum. As further consideration for such loan, the Company agreed to
reduce the exercise price of all of the CMH Advisory Warrants to $3.22 per
share. In addition, the Company agreed to reduce the exercise price of warrants
to purchase 124,159 shares of Common Stock at an exercise price of $3.22 per
share previously issued to Corey M. Horowitz on November 29, 1995 to $1.61 per
share.

     On September 26, 1997, the Company issued to Applewood and CMH, principal
stockholders of the Company, notes in the principal amounts of $350,000 and
$50,000, respectively, bearing interest at the rate of 8% per annum, which,
together with accrued and unpaid interest thereon, will be repaid from the
proceeds of this offering and warrants to purchase 62,080 and 8,869 shares of
Common Stock, respectively (the "September 1997 Private Financing"). In
connection with the September 1997 Private Financing, Robert Russo, Vice
President of Business Development and Secretary of the Company, William Hancock,
Chief Technology Officer and a director of the 

                                       62


Company, and Kenneth Conquest, then Vice President of Engineering of the
Company, delivered to the Company for cancellation 112,373, 86,112 and 10,103
shares of Common Stock, respectively, for an aggregate consideration of $3,360.

     On November 21, 1997, CMH loaned the Company $50,000 at an interest rate of
8% per annum pending the Company's receipt of a certain accounts receivable. As
additional consideration for the loan, the Company agreed to further reduce the
exercise price of the CMH Advisory Warrants to $1.61 per share from $3.22 per
share. The aforementioned loan was repaid in full by the Company on December 12,
1997.

     From March 2, 1998 through May 14, 1998, the Company issued an aggregate
principal amount of $1,750,000 of notes, bearing interest at the rate of 8% per
annum, and warrants to purchase up to 325,919 shares of Common Stock at an
exercise price of $4.83 per share (the "1998 Private Financing"). In connection
with the 1998 Private Financing, Applewood purchased a $1,300,000 principal
amount note and warrants to purchase 242,111 shares of Common Stock, CMH
purchased a $50,000 note and warrants to purchase 9,312 shares of Common Stock,
Mr. Horowitz purchased a $50,000 principal amount note and warrants to purchase
9,312 shares of Common Stock and Herb Karlitz purchased a $25,000 principal
amount note and warrants to purchase 4,656 shares of Common Stock, at purchase
prices of $1,900,000, $50,000, $50,000, and $25,000, respectively. In
connection with the 1998 Private Financing, Messrs. Russo and Hancock delivered
to the Company for cancellation 38,800 and 23,280 shares of Common Stock,
respectively, for an aggregate consideration of $1,000.

     As part of the 1998 Private Financing, in consideration of Applewood's
investment of $1,000,000 in May 1998, the Company, CMH and Applewood entered
into an advisory agreement, which amended the CMH Advisory Agreement, pursuant
to which the Company agreed to increase the cash fee payable to CMH, if the
Company completes a merger or sale of all or substantially all its assets at any
time up to January 15, 2001, from 2% to 3% of the value of the total
consideration received by the Company, and CMH agreed to share such
consideration with Applewood. As further consideration for Applewood's
$1,000,000 investment in May 1998, each of CMH, Mr. Horowitz, Security Partners,
L.P., Messrs. Russo, Hancock and Conquest agreed that for a period of 24 months
from the consummation of this offering, they would not sell in the public market
any securities of the Company owned by them without the consent of Applewood,
unless 60% of the securities owned by Applewood and affiliated parties have been
sold.

     On July 8, 1998, the Company entered into an exchange agreement with
certain holders of outstanding warrants and options to which the Company issued
an aggregate of 596,741 shares of its Common Stock in exchange for cancellation
of outstanding warrants and options to purchase 789,521 shares of the Company's
Common Stock. Pursuant to such agreement, Applewood exchanged warrants to
purchase 339,111 shares of Common Stock, at exercise prices of $4.83 and $6.44
per share, for 261,565 shares of Common Stock, Mr. Horowitz and CMH, exchanged
warrants to purchase an aggregate of 151,652 shares of Common Stock, at exercise
prices ranging from $1.61 to $4.83, for 131,267 shares of Common Stock and Herb
Karlitz exchanged warrants to purchase 11,640 shares of Common Stock, at
exercise prices of $4.83 and $6.44 per share, for 8,572 shares of Common Stock.

                                       63



     Prior to the consummation of this offering, the Company will enter into a
merger agreement with CommHome Systems Corp. ("CommHome"), effective upon
consummation of this offering, pursuant to which the CommHome stockholders have
agreed to exchange all of the outstanding common stock of CommHome for 35,000
shares of Common Stock of the Company. The Company will assume liabilities of
CommHome on the effective date of the merger not in excess of $200,000, which
include $55,000 and $50,000 owed to Avi A. Fogel and Robert P. Olsen,
respectively. Messrs. Fogel and Olsen have agreed to accept 6,875 and 6,200
shares, respectively, of the Company's Common Stock in full satisfaction of such
indebtedness. Avi A. Fogel, President, Chief Executive Officer and a director of
the Company, is also President and Chief Executive Officer of CommHome and owns
51% of the outstanding shares of CommHome.


                            DESCRIPTION OF SECURITIES

     The authorized capital stock of the Company consists of 25,000,000 shares
of Common Stock, par value $0.01 per share, and 5,000,000 shares of Preferred
Stock, par value $.01 per share. As of the date of this Prospectus (after giving
effect to the Pro Forma Adjustments and the Additional Adjustments), Company has
outstanding 2,633,369 shares of Common Stock, held of record by 79 stockholders.
Upon consummation of this offering, there will be 4,508,369 shares of Common
Stock and no shares of Preferred Stock outstanding.

Common Stock

     Holders of Common Stock are entitled to one vote per share on all matters
submitted to a vote of stockholders. There are no cumulative voting rights for
the election of directors, which means that the holders of more than 50% of such
outstanding shares voting for the election of directors can elect all of the
directors of the Company'standing for election. Subject to the rights of any
outstanding class or series of Preferred Stock created by the authority of the
Board of Directors, holders of Common Stock are entitled to received dividends
as and when declared by the Board of Directors out of funds legally available
therefor. Subject to the rights of any outstanding class or series of Preferred
Stock created by the authority of the Board of Directors, in the event of the
liquidation, dissolution or winding up of the Company, the holder of each share
of Common Stock is entitled to share equally in the balance of any of the
Company's assets available for distribution to stockholders. Outstanding shares
of Common Stock do not have subscription or conversion rights and there are no
redemption or sinking fund provisions applicable thereto. Holders of Common
Stock have no preemptive rights to purchase pro-rata portions of new issues of
Common Stock or Preferred Stock of the Company. The outstanding shares of Common
Stock are, and the shares of Common Stock offered by the Company hereby will be,
when issued and sold hereunder, fully paid and non-assessable.

Preferred Stock

     Upon the consummation of this Offering, all 500,000 shares of Series B
Preferred Stock outstanding will be converted into 310,399 shares of Common
Stock (See Note F(1) to Notes to Financial Statements for a description of the
Series B Convertible Preferred Stock). The Board is authorized, subject to any
limitations prescribed by Delaware law, to provide for the issuance of
additional shares of Preferred Stock in one or more series, to establish from
time to time the number 

                                       64


of shares to be included in each such series, to fix the rights, preferences and
privileges of the shares of each wholly unissued series and any qualifications,
limitations or restrictions thereon, and to increase or decrease the number of
shares of any such series (but not below the number of shares of such series
then outstanding), without any further vote or action by the stockholders. The
Board may authorize the issuance of Preferred Stock with voting or conversion
rights that could adversely affect the voting power or other rights of the
holders of Common Stock. Thus, the issuance of Preferred Stock may have the
effect of delaying, deferring or preventing a change in control of the Company.
The Company has no current plan to issue any shares of Preferred Stock.

Warrants and Options

         As of the date of this Prospectus, the Company has outstanding warrants
to purchase 336,007 shares of Common Stock (excluding the Underwriter's Warrants
to purchase 187,500 shares of Common Stock) and options to purchase 294,879
shares of Common Stock (excluding options to purchase 423,908 shares of Common
Stock issued pursuant to the Company's Stock Option Plan). All outstanding
warrants are currently exercisable and outstanding options are currently
exercisable to purchase 100,259 shares of Common Stock. The outstanding warrants
are exercisable at prices ranging from $1.61 to $9.66 and expire between
February 2002, and May 2008. The outstanding options are exercisable at $2.42
per share and expire May 2003.

         The warrants also entitle the holder to certain registration rights
with respect to the shares of Common Stock issuable upon exercise of such
warrants. No warrantholder has any stockholder rights with respect to the shares
issuable upon exercise of warrants held by such holder until such warrants are
exercised and the purchase price is paid for the shares. Each of the warrants
and options also provides, among other things, for the adjustment of the price
per share and number of shares issuable upon exercise of such warrants and
options upon a merger or consolidation of the Company, reclassification of the
Company's securities, a stock split, subdivision or combination of the Company's
securities, the payment of a dividend in Common Stock of the Company or of
certain other dividends or distributions with respect to the Common Stock of the
Company.

Registration Rights of Certain Holders

         The holders of 1,040,612 shares of Common Stock (including warrants
exercisable to purchase 62,856 shares of Common Stock) have been granted certain
demand registration rights, including the right to request on up to two
occasions that the Company file a registration statement with respect to such
shares under the Securities Act and use its best efforts to effect any such
registration. In addition, the holders of 1,453,442 shares of Common Stock
(including warrants exercisable to purchase 336,007 shares) are entitled to
piggyback registration rights with respect to such shares. If the Company
proposes to register any of its securities, either for its own account or for
the account of other stockholders, the Company is required to notify these
holders and, subject to certain conditions and limitations, to include in such
registration all of the shares of Common Stock requested to be included by such
holders. All holders of registration rights have agreed to waive such rights in
connection with this offering and not to exercise any such rights for one year
from the date of this Prospectus, without the Underwriter's prior written
consent.

                                       65


     In connection with this offering, the Company has agreed to grant the
Underwriter certain demand and piggyback registration rights with respect to the
shares of Common Stock issuable upon exercise of the Underwriter's Warrants. See
"Underwriting."

Delaware Anti-Takeover Law

     The Company is subject to the provisions of Section 203 of the Delaware
General Corporation Law (the "Anti-Takeover Law") regulating corporate
takeovers. The Anti-Takeover Law prevents certain Delaware corporations,
including those whose securities are listed on the Nasdaq SmallCap Market from
engaging, under certain circumstances, in a "business combination" (which
includes a merger or sale of more than 10% of the corporation's assets) with any
"interested stockholder" (a stockholder who owns 15% or more of the
corporation's outstanding voting stock) for three years following the date that
such stockholder became an "interested stockholder" unless the business
combination is approved in a prescribed manner. A Delaware corporation may "opt
out" of the Anti-Takeover Law with an express provision in its original or
amended certificate of incorporation or an express provision in its Bylaws
resulting from a stockholders' amendment approved by at least a majority of the
outstanding voting shares. The Company has not "opted out" of the provisions of
the Anti-Takeover Law.

     The Transfer Agent for the Company's Common Stock is American Stock
Transfer and Trust Company, 40 Wall Street, New York, New York 10005.

under the Securities Act, except for any shares purchased by an "affiliate of
the Company" (in general, a person who has a controlling position with regard to
the Company), which will be subject to the resale limitations of Rule 144
promulgated under the Securities Act.

     All of the remaining 2,633,369 shares of Common Stock currently outstanding
are "restricted securities" or owned by "affiliates" (as those terms are defined
in Rule 144) and thus may not be sold publicly unless they are registered under
the Securities Act or are sold pursuant to Rule 144 or another exemption from
registration. Of the 2,633,369 restricted shares, an aggregate of 1,977,124
shares will be eligible for sale, without registration, under Rule 144 (subject
to certain volume limitations prescribed by such rule and to the contractual
restrictions described below), commencing 90 days following the date of this
Prospectus and the balance of such shares will become eligible for sale at
various times commencing February 1999. Holders of all of the 2,633,369
outstanding shares of Common Stock have agreed not to (i) sell or otherwise
dispose of any shares of Common Stock or (ii) exercise any rights held by such
holders to cause the Company to register any shares of Common Stock for sale
pursuant to the Securities Act, in each case, for a period of 12 months
following the date of this Prospectus, without the Underwriter's prior written
consent.

                                       66


     In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this Prospectus, a person (or persons whose shares are aggregated)
who has beneficially owned restricted securities for at least one year
(including the holding period of any prior owner except an affiliate of the
Company) would be entitled to sell within any three-month period a number of
shares that does not exceed the greater of: (i) 1% of the number of shares of
Common Stock then outstanding (which will equal approximately 45,083 shares
immediately following the consummation of this offering); or (ii) the average
weekly trading volume of the Common Stock during the four calendar weeks
preceding the filing of a Form 144 with respect to such sale. Sales under Rule
144 are also subject to certain manner of sale provisions, notice requirements
and the availability of current public information about the Company. Under Rule
144(k), a person who is not deemed to have been an affiliate of the Company at
any time during the 90 days preceding a sale, and who has beneficially owned the
shares proposed to be sold for at least two years (including the holding period
of any prior owner except an affiliate of the Company), is entitled to sell such
shares without complying with the manner of sale, public information, volume
limitation or notice provisions of Rule 144. Unless otherwise restricted,
"144(k) shares" may therefore be sold immediately upon the consummation of this
offering.

     Rule 701 permits resales of shares in reliance upon Rule 144 but without
compliance with certain restrictions, including the holding period requirement,
of Rule 144. Any employee, officer or director of or consultant to the Company
who purchased his or her shares pursuant to a written compensatory plan or
contract may be entitled to rely on the resale provisions of Rule 701. Rule 701
permits affiliates to sell their Rule 701 shares under Rule 144 without
complying with the holding period requirements of Rule 144. Rule 701 further
provides that non-affiliates may sell such shares in reliance on Rule 144
without having to comply with the holding period, public information, volume
limitation or notice provisions of Rule 144. In both cases, a holder of Rule 701
shares is required to wait until 90 days after the date of this Prospectus
before selling such shares.

     Prior to this offering, there has been no market for the Common Stock and
no prediction can be made as to the effect, if any, that market sales of shares
of Common Stock or the availability of such shares for sale will have on the
market prices of the Common Stock prevailing from time to time. Nevertheless,
the possibility that substantial amounts of Common Stock may be sold in the
public market may adversely affect prevailing market prices for the Common Stock
and could impair the Company's ability to raise capital through the sale of its
equity securities.


                                  UNDERWRITING

     Whale Securities Co., L.P. (the "Underwriter") has agreed, subject to the
terms and conditions contained in the Underwriting Agreement, to purchase the
1,875,000 shares of Common Stock offered hereby from the Company. The
Underwriter is committed to purchase and pay for all of the shares of Common
Stock offered hereby if any of such securities are purchased. The shares of
Common Stock are being offered by the Underwriter, subject to prior sale, when,
as and if delivered to and accepted by the Underwriter and subject to certain
legal matters by counsel and to certain other conditions.

                                       67




     The Underwriter has advised the Company that it proposes to offer the
shares of Common Stock to the public at the public offering price set forth on
the cover page of this Prospectus. The Underwriter may allow certain dealers who
are member of the National Association of Securities Dealers, Inc. (the "NASD")
concessions, not in excess of $ per share, of which not in excess of $ per share
may be reallowed to other dealers who are members of the NASD.

     The Company has granted to Underwriter an option, exercisable for 45 days
following the date of this Prospectus, to purchase up to 281,250 shares at the
public offering price set forth on the cover page of this Prospectus, less
underwriting discounts and commissions. The Underwriter may exercise this option
in whole or, from time to time, in part, solely for the purpose of covering
over-allotments, if any, made in connection with the sale of the shares offered
hereby.

     The Company has agreed to pay to the Underwriter a non-accountable expense
allowance equal to 3% of the gross proceeds derived from the sale of the shares
offered hereby, including any securities sold prior to the Underwriter's
over-allotment option, $50,000 of which has been paid as of the date of this
Prospectus. The Company has also agreed to pay all expenses in connection with
qualifying the shares offered under the laws of such states as the Underwriter
may designate, including expenses of counsel retained for such purpose by the
Underwriter.

     The Company has agreed to sell to the Underwriter and its designees, for an
aggregate of $100 (the "Underwriter's Warrants") to purchase up to 187,500
shares of Common stock at an exercise price of $13.20 per share (165% of the
public offering price per share). The Underwriter's Warrants may not be assigned
or hypothecated for one year following the date of this Prospectus, except to
the officers and partners of the Underwriter and members of the selling group,
and are exercisable at any time, in whole or in part, during the four-year
period commencing one year from the date of this Prospectus (the "Warrant
Exercise Term"). During the Warrant Exercise Term, the holders of the
Underwriter's Warrants are given, at nominal cost, the opportunity to profit
from a rise in the market price of the Common Stock. To the extent that the
Warrants are exercised, dilution to the interests of the Company's stockholders
will occur. Further, the terms upon which the Company will be able to obtain
additional equity capital may be adversely affected, since the holders of the
Underwriter's Warrants can be expected to exercise them at a time when the
Company would, in all likelihood, be able to obtain any needed capital on terms
more favorable to the Company than in the Underwriter's Warrants. Any profit
realized by the Underwriter on the sale of the Underwriter's Warrants, the
underlying shares of Common Stock or the underlying warrants may be deemed
additional underwriting compensation. The Underwriter's Warrants contain a
cashless exercise provision. Subject to certain limitations and exclusions, the
Company has agreed that, upon the request of the holders of the majority of the
Underwriter's Warrants, the Company will (at its own expense), on one occasion
during the Warrant Exercise term, register the Underwriter's Warrants and the
securities underlying the Underwriter's Warrants under the Securities Act and
that it will include the Underwriter's Warrants and all such underlying
securities in any appropriate registration statement which is filed by the
Company under the Securities Act during the seven years following the date of
this Prospectus.

         The Company has agreed, for a period of five years from the date of
this Prospectus, if so requested by the Underwriter, to recommend and use its
best efforts to elect a designee of the Underwriter as a director of the
Company. The Company's officers, directors and principal 

                                       68


stockholders have agreed to vote their shares of Common Stock in favor of such
designee. The Underwriter has not yet exercised its right to designate such a
person.

     All of the Company's officers, directors and securityholders have agreed
not to sell or otherwise dispose any of their securities in the public markets
for a period of twelve months from the date of this Prospectus without the
Underwriter's prior written consent.

     The Underwriter has informed the Company that it does not expect sales of
the securities offered discretionary accounts to exceed 1% of the shares offered
hereby.

     The Company has agreed to indemnify the Underwriter against certain civil
liabilities, including liabilities under the Securities Act.

     Prior to this offering there has been no public market for the Common
Stock. Accordingly, the initial public offering price of the Common Stock will
be determined by negotiation between the Company and the Underwriter and may not
necessarily be related to the Company's asset value, net worth or other
established criteria of value. Factors to be considered in determining such
price include the Company's financial condition and prospects, an assessment of
the Company's management, market prices of similar securities of comparable
publicly-traded companies, certain financial and operating information of
companies engaged in activities similar to those of the Company and the general
condition of the securities market.

     In order to facilitate the offering, the Underwriter may engage in
transactions that stabilize, maintain, otherwise affect the price of the Common
Stock. Specifically, the Underwriter may over-allotment in connection with the
offering, creating a short position in the Common Stock for its own account. In
addition, to cover over-allotments or to stabilize the price of the Common
Stock, the Underwriter may bid for, and purchase, shares of Common Stock in the
open market. The Underwriter may also reclaim selling concessions allowed to a
dealer for distributing the Common Stock in the offering, if the Underwriter
repurchases previously distributed Common Stock in transactions to cover short
positions, in stabilization transactions or otherwise. Any of these activities
may stabilize or maintain the market price of the Common Stock above independent
market levels. The Underwriter is not required to engage in these activities,
and may end any of these activities at any time.


                                  LEGAL MATTERS

     The validity of the Common Stock offered hereby will be passed upon for the
Company by Bizar Martin & Taub, LLP. Certain legal matters in connection with
this offering will be passed upon for the Underwriter by Tenzer Greenblatt LLP.
Bizar Martin & Taub, LLP owns currently exercisable warrants to purchase 9,312
shares of the Company's Common Stock at an exercise price of $6.44 per share.

INDEPENDENT AUDITORS' REPORT

Board of Directors and Stockholders
Network-1 Security Solutions, Inc.
Wellesley, Massachusetts


We have audited the accompanying balance sheets of Network-1 Security Solutions,
Inc. (the "Company") as of December 31, 1996 and 1997 and the related statements
of operations, stockholders' equity and cash flows for each of the years then
ended. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements enumerated above present fairly, in all
material respects, the financial position of Network-1 Security Solutions, Inc.
as of December 31, 1996 and 1997 and the results of its operations and its cash
flows for each of the years then ended in conformity with generally accepted
accounting principles.

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note A to the
financial statements, the Company has incurred substantial losses from
operations, and as of December 31, 1997 has a working capital deficiency of
$661,000 and a stockholders' deficiency of $75,000. These factors raise
substantial doubt about the Company's ability to continue as a going concern.
Management's plans in regard to these matters are also described in Note A. The
financial statements do not include any adjustments that might result from the
outcome of this uncertainty.

Notes to Financial Statements
(unaudited with respect to data as of March 31, 1998 and for
the three-month periods ended March 31, 1997 and 1998)


NOTE A - THE COMPANY AND BASIS OF PRESENTATION

Network-1 Security Solutions, Inc. (the "Company"), formerly known as Network-1
Software & Technology, Inc., develops, markets, licenses and supports its
proprietary network security software products designed to provide comprehensive
security to computer networks. The Company also provides maintenance and network
consulting and training services.

The accompanying financial statements have been prepared on a going concern
basis. As reflected in the accompanying financial statements, the Company has
incurred substantial losses from operations and as of December 31, 1997 has a
working capital deficiency of $661,000 and a stockholders' deficiency of
$75,000. Subsequent to December 31, 1997 through May 14, 1998, the Company
received $1,750,000 in short-term debt financing, a significant portion of which
was from principal stockholders of the Company. However, the Company will
require additional financing to satisfy its obligations and fund its operations
through December 31, 1998. Also, in May 1998, the Company'signed a letter of
intent with an underwriter for the sale of its securities in an initial public
offering (the "Offering"). There is no assurance, however, that the Offering
will be consummated or that the Company will be able to obtain alternative
financing. The above factors give rise to substantial doubt as to the ability of
the Company to continue as a going concern. The financial statements do not
include any adjustments that might result from the outcome of this uncertainty.

On July 17, 1998, the stockholders approved a 1 for 1.610831 reverse split of
the outstanding shares of the Company's common stock. The accompanying financial
statements have been retroactively adjusted to reflect the split and all
references to numbers of common shares, options, warrants and per share amounts
have been restated to give effect to the split.


NOTE B - SIGNIFICANT ACCOUNTING POLICIES

[1]  Cash equivalents:

     The Company considers all highly liquid short-term investments purchased
     with a maturity of three months or less to be cash equivalents.

[2]  Revenue recognition:

     In October 1997, the AICPA issued Statement of Position ("SOP") No. 97-2,
     "Software Revenue Recognition," which the Company adopted, effective
     January 1, 1997. Such adoption had no effect on the Company's methods of
     recognizing revenue from its license and service activities. Prior to 1997,
     the Company's revenue recognition policy was in accordance with SOP No.
     91-1, "Software Revenue Recognition."

     License revenue is recognized upon delivery of software or delivery of a
     required software key. Service revenues consist of maintenance, consulting
     and training services. Annual renewable maintenance fees are a separate
     component of each contract, and are recognized ratably over the contract
     term. Consulting and training revenues are recognized as such services are
     performed.

[3]  Equipment and fixtures:

     Equipment and fixtures are stated at cost and are depreciated using the
     straight-line method over their estimated useful lives of five years.

the three-month periods ended March 31, 1997 and 1998)

NOTE B - SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

[4]  Software development costs:

     Costs to maintain developed programs and development costs incurred to
     establish the technological feasibility of computer software are expensed
     as incurred. The Company capitalizes costs incurred in producing computer
     software after technological feasibility of the software has been
     established. Such costs are amortized based on current and estimated future
     revenue of each product with an annual minimum equal to the straight-line
     amortization over the remaining estimated economic life of the product. The
     Company estimates the economic life of its software to be three years. At
     each balance sheet date, the unamortized capitalized software costs of each
     product are compared with the net realizable value of that product and any
     excess capitalized costs are written off.

[5]  Income taxes:

     The Company utilizes the liability method of accounting for income taxes.
     Under such method, deferred tax assets and liabilities are recognized for
     the future tax consequences attributable to differences between the
     financial statement carrying amounts of existing assets and liabilities and
     their respective tax bases. Deferred tax assets and liabilities are
     measured using enacted tax rates in effect at the balance sheet date. The
     resulting asset or liability is adjusted to reflect enacted changes in tax
     law.

[6]  Loss per share:

     During 1997, the Company adopted Statement of Financial Accounting
     Standards No. 128, "Earnings Per Share" ("SFAS No. 128"). SFAS No. 128
     requires the reporting of basic and diluted earnings/loss per share. Basic
     loss per share is calculated by dividing net loss by the weighted average
     number of outstanding common shares during the year. Diluted per share data
     includes the dilutive effects of options, warrants and convertible
     securities. As all potential common shares are anti-dilutive, they are not
     included in the calculation of diluted loss per share. Loss per share for
     1996 has been presented to conform to SFAS No. 128.

[7]  Use of estimates:

     The preparation of financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the reported amounts of assets and liabilities and
     disclosure of contingent assets and liabilities at the date of the
     financial statements and the reported amounts of revenues and expenses
     during the reporting period. Actual results could differ from those
     estimates.

[8]  Financial instruments:

     The carrying amounts of accounts receivable, accounts payable, accrued
     expenses, capitalized lease obligations and notes payable approximate their
     fair value as the interest rates on the Company's indebtedness approximate
     current market rates and due to the short period to maturity of these
     instruments.

NOTE B - SIGNIFICANT ACCOUNTING POLICIES  (CONTINUED)

[9]  Stock-based compensation:

     In October 1995, the Financial Accounting Standards Board issued Statement
     of Financial Accounting Standards No. 123 ("SFAS No. 123"), "Accounting for
     Stock-Based Compensation". SFAS No. 123 encourages, but does not require,
     companies to record compensation cost for stock-based employee compensation
     plans at fair value. The Company has elected to continue to account for its
     employee stock-based compensation plans using the intrinsic value method
     prescribed by Accounting Principles Board Opinion No. 25 ("APB No. 25"),
     Accounting for Stock Issued to Employees" and to disclose the pro forma
     effect on net loss per share had the fair value of options been expensed.
     Under the provisions of APB No. 25, compensation cost for stock options is
     measured as the excess, if any, of the estimated market value of the
     Company's common stock at the date of the grant over the amount an employee
     must pay to acquire the stock.

[10] Interim financial statements:

     changes in stockholders' equity for the three-month period then ended and
     the statements of operations and cash flows for the three-month periods

     all adjustments (consisting only of normal recurring accruals) considered
     necessary for a fair presentation have been included. The results of
     operations for the three-month period ended March 31, 1998 are not
     necessarily indicative of the results to be expected for the year ended

NOTE E - NOTES PAYABLE  (CONTINUED)

(1)  In connection with the issuance of the notes, including $250,000 issued to
     an entity which is a principal stockholder of the Company, the Company
     issued ten-year warrants valued at $290,000 to purchase 90,791 shares of
     the Company's common stock at an exercise price of $6.44 per share,
     increasing the effective interest rate on the notes to 91%.

(2)  In connection with the issuance of the notes, the Company issued ten-year
     warrants valued at $159,000 to purchase 48,888 shares of the Company's
     common stock at an exercise price of $6.44 per share, increasing the
     effective interest rate to 94%.

(3)  In connection with the issuance of the note to a corporation wholly owned
     by the Chairman of the Board and a principal stockholder of the Company,
     the Company agreed to reduce the exercise price of previously issued
     warrants to the noteholder from $6.44 per share (31,040 shares) and $8.05
     per share (31,040 shares) to $3.22 per share (see Note G[5]). In addition,
     the Company agreed to reduce the exercise price of warrants to purchase
     124,159 shares of common stock at an exercise price of $3.22 per share
     previously issued to the noteholder to $1.61 per share. The Company valued
     the modified warrants at $45,000 in excess of the value ascribed to the
     original warrants, increasing the effective interest rate to 96%. The
     warrants exercisable at $3.22 per share were further reduced to $1.61 per
     share in connection with the issuance in November 1997 of a note for
     $50,000 to the same corporation referred to above which was repaid in
     December 1997. This modification was valued at $22,000 in excess of the
     value ascribed to the warrants as previously modified.

(4)  In connection with the issuance of the notes to an entity which is a
     principal stockholder of the Company and to the corporation referred to in
     (3) above, the Company issued ten-year warrants valued at $168,000 to
     purchase 70,949 shares of the Company's common stock at an exercise price
     of $4.83 per share, increasing the effective interest rate to 86%.

(5)  In connection with the issuance of the notes, $350,000 of which are payable
     to the entities referred to in (4) above, the Company issued ten-year
     warrants valued at $175,000 to purchase 74,496 shares of the Company's
     common stock at an exercise price of $4.83 per share, increasing the
     effective interest rate to 92%.

The proceeds from the issuance of the notes were allocated to the debt and the
warrants based on their estimated fair values. The Company estimated the fair
value of these warrants using the Black-Scholes pricing model and has accounted
for this amount as a debt discount to be amortized over the life of the debt.

Interest expense for the years ended December 31, 1996, 1997 and for the three
months ended March 31, 1997 and 1998 includes $325,000, $268,000, $10,000 and
$117,000, respectively, of interest and amortization of debt discount on notes
to related parties.

In April and May 1998, the Company borrowed an additional $1,350,000. The notes
bear interest at 8% per annum and are payable on the earlier of a) one year b)
the date upon which the Company receives $6,000,000 net proceeds of equity or
debt financing from one or a series of transactions c) a sale of all of the
Company's assets or d) a merger or consolidation of the Company. In connection
therewith, the Company issued ten-year warrants valued at $591,000 to purchase
251,423 shares of the Company's common stock at an exercise price of $4.83 per
share increasing the effective interest rate to 92%.

NOTE F - STOCKHOLDERS' EQUITY

[1] Preferred stock:

     The Company has outstanding 500,000 shares of Series B convertible
     preferred stock. Such stock is convertible on a 1.610831-to-1 basis into
     common shares and automatically converts into common shares upon the
     completion of an initial public offering of the Company's securities which
     results in gross proceeds to the Company of a minimum of $4,000,000. The
     preferred stock has identical voting rights as the Company's common stock
     and has a liquidation preference of $1.00 per share.

[2]  Stock options and warrants:

     During 1996, the Board of Directors and stockholders approved the adoption
     of the 1996 Stock Option Plan (the "1996 Plan"). The 1996 Plan, as amended,
     provides for the granting of both incentive and non-qualified options to
     purchase up to 750,000 shares of common stock of the Company.

     The term of options granted under the 1996 Plan may not exceed ten years
     (five years in the case of an incentive stock option granted to an optionee
     owning more than 10% of the voting stock of the Company). The option price
     for incentive stock options can not be less than 100% of the fair market
     value of the shares of common stock at the time the option is granted (110%
     for a 10% stockholder). The exercise price for non-qualified options is set
     by the Compensation Committee in its discretion.

     The following table summarizes the activity under the 1996 Plan:



                                                         Year Ended December 31,                           Three Months Ended

[2]  Software distribution agreements:

     [a] In June 1997, the Company entered into a software distribution
         agreement pursuant to which the Company licensed, on a nonexclusive
         basis, the right to incorporate and/or bundle certain technology of the
         Company, with the customer's products. In connection therewith, the
         Company, which is entitled to royalties based on the customer's sales,
         received a $500,000, nonrefundable prepaid royalty, which is included
         in license revenue for the year ended December 31, 1997.

     [b] In September 1997, the Company entered into a software distribution
         agreement, pursuant to which the Company has the right to incorporate
         certain technology into its software. The Company is required to make
         certain royalty payments based on unit sales as defined. The Company is
         obligated to pay a minimum of $100,000 in royalties pursuant to the
         agreement for the period September 1997 to March 30, 1999. As of
         December 31, 1997 and March 31, 1998, accrued royalty payable was
         approximately $29,000 and $37,000, respectively.

     [c] In July 1996, the Company entered into an agreement pursuant to which
         certain technology was developed for the Company. The Company is
         required to make certain royalty payments based on unit sales as
         defined, up to a maximum royalty payment of $100,000. For the year

     President and Chief Executive Officer which provides for a base salary of
     $150,000, subject to annual increases of up to 20% by the Board of
     Directors at their discretion. The agreement also provides for an annual
     bonus of up to $50,000 as determined by the Board of Directors in its
     discretion. The agreement expires in May 2002. In connection therewith, the
     Company granted the President a five-year option to purchase 294,879 shares
     of the Company's common stock at an exercise price of $2.42 per share. The
     option vests 34% immediately and then 22% per year thereafter. As the
     estimated fair value of the Company's common stock at the date of grant of
     the option ($5.60 per share) was in excess of the exercise price the
     Company will incur aggregate compensation expense of approximately $900,000
     over the four-year service period.

The Company has recorded a valuation allowance for the full amount of its
deferred tax assets as the likelihood of its future realization cannot be
presently determined.

The difference between the tax benefit and the amount that would be computed by
applying the statutory federal income tax rate to loss before taxes is
attributable to the following:

At December 31, 1997, the Company has available net operating loss carryforwards
to reduce future federal taxable income of approximately $5,500,000 for tax
reporting purposes which expire from 2009 through 2012. Pursuant to the

is subject to certain limitations based on changes in the ownership of the
Company's stock that have occurred or may occur.

NOTE J - SUBSEQUENT EVENTS

[1]  On July 8, 1998, the Company entered into an agreement with certain of its
     option and warrant holders pursuant to which the Company issued 596,741
     shares of its common stock in exchange for cancellation of outstanding
     warrants to purchase 789,521 shares of the Company's common stock.

[2]  The Company has agreed in principle to acquire for 35,000 shares of its
     common stock and the assumption of liabilities of up to $200,000 all of the
     outstanding common stock of CommHome Systems Corp. ("CommHome") effective
     upon the consummation of the offering. The Company's President is also the
     President of CommHome and owns 51% of its outstanding common stock. Of the
     assumed liabilities, $105,000 is owed to two officers of the Company and
     will be satisfied by the issuance of 13,125 shares of common stock. The
     Company will incur a charge of approximately $465,000 for purchased
     research and development upon the acquisition. CommHome is a development
     stage company and has had no revenues. The principal activity has been the
     design of residential networking solutions. The Company intends to
     incorporate CommHome's designs into its future security products.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

Item 24. Indemnification of Directors and Officers

     As permitted by Section 102(b)(7) of the Delaware General Corporation Law
(the "GCL"), Article VI of the Company's Amended and Restated Certificate of
Incorporation, filed as Exhibit 3.1 hereto, includes a provision that eliminates
any director's personal liability to the Company or its stockholders for
monetary damages for breach of fiduciary duty as a director. Such elimination of
personal liability does not apply to the following: (i) breach of the duty of
loyalty to the Company or its stockholders; (ii) acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of the law;
(iii) payment of an illegal dividend or an illegal redemption or purchase of the
Company's stock, pursuant to Section 174 of the GCL; or (iv) any transaction
from which the director derived an improper benefit. If the GCL is amended to
authorize corporate action further eliminating or limiting the personal
liability of directors, then the liability of a director of the Company'shall be
eliminated or limited to the fullest extent permitted by the GCL, as so amended.
Any repeal or modification of this Article by the stockholders of the Company
shall not adversely affect any right or protection of a director of the Company
with respect to events occurring prior to the time of such repeal or
modification.

     As permitted by Section 145 of the GCL, pursuant to Article VII of the
Company's Amended and Restated Certificate of Incorporation, the Company, to the
fullest extent permitted by the provisions of the GCL, as now or hereafter in
effect, indemnifies any director, officer, employee or agent of the Company and
certain other persons serving at the request of the Company in related
capacities against amounts paid and expenses incurred in connection with an
action or proceeding to which that person is or is threatened to be made a party
by reasons of such position, if such person shall have acted in good faith and
in a manner he reasonably believed to be in or not opposed to the best interests
of the Company and, in any criminal proceeding, if such person had no reasonable
cause to believe his conduct was unlawful; provided that, in the case of actions
brought by or in the right of the Company, no indemnification shall be made with
respect to any matter as to which such person shall have been adjudged to be
liable to the Company unless and only to the extent that the adjudicating court
determines that such indemnification is proper under the circumstances. The
indemnification provided by Article VII of the Company's Amended and Restated
Certificate of Incorporation does not limit or exclude any rights, indemnities
or limitations of liability to which any person may be entitled, whether as a
matter of law, under the Bylaws of the Company, by agreement, vote of the
stockholders or vote of disinterested directors of the Company or otherwise.

     The Company believes that the indemnification provisions contained in
Article VI and Article VII of the Company's Amended and Restated Certificate of
Incorporation have assisted and will assist the Company in attracting and
retaining qualified individuals to serve as directors and officers.

     The Underwriting Agreement, filed as Exhibit 1.1 hereto, provides for
indemnification by the Underwriter of the Company, its directors and officers,
and by the Company of the Underwriter, for certain liabilities, including
liabilities under the Act, and affords certain rights of contribution with
respect thereto.

Item 26. Recent Sales of Unregistered Securities

     During the past three years, the Company has issued unregistered securities
to the persons described below. No underwriting discounts or commissions were
paid in connection with such issuance of securities, except in connection with
the Company's issuance of an aggregate 667,357 shares of Common Stock on March
14, 1996 and March 21, 1996 (the "March 1996 Private Offering," as further
described below under paragraph 5). In issuing the securities described below,
the Company relied upon the exemption from the registration requirements of the
Securities Act of 1933, as amended (the "Securities Act"), by reason of Section
4(2) thereof and Regulation D promulgated thereunder, based on the fact that
each investor was either an "accredited investor" as such term is defined in
Rule 501 of Regulation D promulgated under the Securities Act or such investor
had such knowledge and experience in financial and business matters that such
person was capable of evaluating the merits and risks of the investment. The
share amounts below reflect a stock split at the rate of 12,836.97-to-1 on March
2, 1994, and a reverse stock split at the rate of 1-for-1.61083 on July 20,
1998.

     purchase 124,160 shares of Common Stock at an exercise price of $3.22 per

                                      II-2


(2)  On November 29, 1995, the Company issued to the CAPCOR Employee Pension

(4)  On March 14, 1996, the Company issued to Bizar Martin & Taub, LLP warrants

     sales commission (or $193,500). The Company also issued to GKN Securities
     Corp., related parties and Barington Capital Group, L.P. options to
     purchase an aggregate 66,736 shares of Common Stock at an exercise price of

     principal amount of $700,000.

(7)  On March 21, 1996, the Company issued to J. Robert Scott, Inc. 6,467 shares

(12) On June 3, 1996, the Company issued to Navigator Global Fund 1,785 shares
     of Common Stock in consideration for payment of $6.44 per share or
     aggregate consideration of $11,500.

                                      II-3


(13) On October 3, 1996, the Company issued to each of Craig Bandes and Mona
     Geller 7,760 shares of Common Stock, upon the exercise of stock options by
     Bandes and Geller at an exercise price of $1.61 per share or aggregate
     consideration of $25,000. The stock options had been issued pursuant to
     Stock Option Agreements, dated April 4, 1994, in consideration for
     financial advisory services rendered to the Company.

(14) On October 11, 1996, the Company issued to CMH Capital Management Corp.
     ("CMH") warrants to purchase 31,040 shares of Common Stock at an exercise
     price of $8.05 per share, expiring October 11, 2003, in consideration for
     financial advisory services.

(15) On October 22, 1996, the Company issued to Communica, Inc. and related
     parties 9,312 shares of Common Stock in consideration for services
     rendered.

(16) The Company's Stock Option Plan provides for the grant of stock options to
     key employees, directors, and consultants of the Company (the "Stock Option
     Plan"). Under the Stock Option Plan, employees (including officers and
     employee directors) are eligible to receive grants of incentive stock
     options, which are intended to be "Incentive Stock Options" as defined by
     Section 422 of the Internal Revenue Code of 1986, as amended. Employees
     (including officers), directors of the Company or any affiliates or
     consultants are eligible to receive grants of non-qualified options. An
     aggregate of 465,598 shares of Common Stock has been reserved for issuance
     upon exercise of outstanding options issued under the Stock Option Plan.
     The Company believes that the Employee Stock Option grants described in
     this paragraph are exempt from the registration requirements of the
     Securities Act by reason of Rule 701 promulgated thereunder, because such

names as required by the Underwriter to permit prompt delivery to each
purchaser.

                                     II-10


     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 (the "Securities Act") may be permitted to directors, officers and
controlling persons of the registrant pursuant to the foregoing provisions, or
otherwise, the registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act and is, therefore, unenforceable. In the event
that a claim from indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question of whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

     For purpose of determining any liability under the Securities of 1933, each
post-effective amendment that contains a Form of Prospectus shall be deemed to
be a new registration statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.

     For purposes of determining any liability under the Securities Act, the
information omitted from the Form of Prospectus filed as part of this
Registration Statement in reliance upon Rule 430A and contained in the Form of
Prospectus filed by Company pursuant to Rule 424(b)(1) or (4) or 497(h) under
the Securities Act shall be deemed to be part of this Registration Statement as
of the time it was declared effective.
