	NOTE 1:-	GENERAL
		a.	Radware Ltd. ("the Company"), an Israeli corporation commenced operations in April 1997. The Company and its subsidiaries ("the Group") are engaged in the development, manufacture and sale of Application Delivery and Application Security solutions that provide end-to-end availability, performance and security of business-critical network applications. The Company's products are marketed worldwide.
		b.	The Company has established wholly-owned subsidiaries in the United States, France, Germany, Singapore, the United Kingdom, Japan, Korea, Canada, India, Australia Italy and China. The Company holds 91.0% of its Israeli subsidiary. In addition, the Company has established representative offices in China and Taiwan. The Company's subsidiaries are engaged primarily in sales, marketing and support activities, except for the Israeli subsidiary which is engaged primarily in real-time consumer applications across the web. The Israeli subsidiary's operations were immaterial for the years ended December 31, 2011, 2012 and 2013.
		c.	The Company depends on four major suppliers to supply certain components for the production of its products. If one of these suppliers fails to deliver or delays the delivery of the necessary components, the Company will be required to seek alternative sources of supply. A change in suppliers could result in manufacturing delays, which could cause a possible loss of sales and, consequently, could adversely affect the Company's results of operations and financial position.
		d.	On April 12, 2013, the Company effected a stock split of its Ordinary shares of two for one (2:1) and accordingly the par value of the Ordinary shares has changed from NIS 0.1 to NIS 0.05 per share. The earnings per share figures or results, stock options activity and share data presented for all periods were adjusted to reflect the stock split.

SIGNIFICANT ACCOUNTING POLICIES [Abstract]	'
SIGNIFICANT ACCOUNTING POLICIES	'
	NOTE 2:-	SIGNIFICANT ACCOUNTING POLICIES
	The consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States ("U.S. GAAP").
		a.	Use of estimates:
	The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates, judgments and assumptions. The Company's management believes that the estimates, judgments and assumptions used are reasonable based upon information available at the time they are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
	On an ongoing basis, the Company's management evaluates estimates, including those related to fair values and useful lives of intangible assets, tax assets and liabilities, fair values of stock-based awards, as well as in estimates used in applying the revenue recognition policy related to separation of multiple elements. Such estimates are based on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities.
		b.	Financial statements in United States dollars:
	A majority of the revenues of the Company and its subsidiaries are denominated in U.S. dollars ("dollar" or "dollars"). In addition, a substantial portion of the Company's and certain of its subsidiaries' costs are denominated in dollars. The Company's management believes that the dollar is the primary currency of the economic environment in which the Company and its subsidiaries operate. Thus, the functional and reporting currency of the Company and its subsidiaries is the dollar. Accordingly, monetary accounts maintained in currencies other than the dollar are re-measured into U.S. dollars in accordance with Accounting Standards Codification ("ASC") No. 830 "Foreign Currency Matters". Changes in currency exchange rates between the Company's functional currency and the currency in which a transaction is denominated are included in the Company's results of operations as financial income (expense) in the period in which the currency exchange rates change.
		c.	Principles of consolidation:
	The consolidated financial statements include the accounts of the Company and its subsidiaries. Intercompany balances and transactions including profits from intercompany sales not yet realized outside the Group, have been eliminated upon consolidation.
		d.	Cash equivalents:
	Cash equivalents are short-term highly liquid investments that are readily convertible to cash with original maturities of three months or less, at acquisition.
		e.	Bank deposits:
	Bank deposits with maturities of more than three months but less than one year are included in short-term deposits. Such short-term deposits are stated at cost which approximates market values.
	Bank deposits with maturities of more than one year are included in long-term deposits. Deposits as of December 31, 2013 do not have contractual maturities that exceed two years. Such long-term deposits are stated at cost which approximates market values.
		f.	Investment in marketable securities:
	The Company accounts for investments in marketable debt securities in accordance with ACS No. 320, "Investments- Debt and equity Securities". Management determines the appropriate classification of its investments in debt securities at the time of purchase and reevaluates such determinations at each balance sheet date.
	The Company classified all of its debt securities as available-for-sale securities. Available-for-sale securities are carried at fair value, with the unrealized gains and losses reported in "accumulated other comprehensive income (loss)" in shareholders' equity. Realized gains and losses on sales of investments are included in financial income, net and are derived using the specific identification method for determining the cost of securities.
	The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization together with interest and dividends on securities are included in financial income, net.
	The Company recognizes an impairment charge when a decline in the fair value of its investments below the cost basis is judged to be other-than-temporary. The factors considered in making such a determination include the duration and severity of the impairment, the reason for the decline in value, the potential recovery period and the Company's intent to sell, including whether it is more likely than not that the Company will be required to sell the investment before recovery of cost basis. For securities that are deemed other-than-temporarily impaired, the amount of impairment recognized in the statement of income (operations) is limited to the amount related to credit losses, while impairment related to other factors is recognized in other comprehensive income. During the years 2011, 2012 and 2013, the Company did not record any other-than-temporary impairment loss with respect to its marketable securities.
		g.	Inventories:
	Inventories are stated at the lower of cost or market value. Inventory write-off is provided to cover risks arising from slow-moving items, technological obsolescence, excess inventories and discontinued products. Inventory write-off totaled $ 1,205, $ 1,147 and $ 464 in 2011, 2012 and 2013, respectively, and has been included in cost of revenues.
	Cost is determined as follows:
	Raw materials and components - using the "first-in, first-out" method.
	Work-in-progress and finished products - raw materials as above with the addition of subcontracting costs - calculated on the basis of direct subcontractors costs and with direct overhead costs.
		h.	Property and equipment:
	Property and equipment are stated at cost, net of accumulated depreciation. Depreciation is calculated by the straight-line method over the estimated useful lives of the assets at the following annual rates:
		%
	Computer, peripheral equipment and software	15 - 33 (mainly 33 )
	Office furniture and equipment	6 - 20 (mainly 15)
	Leasehold improvements	Over the shorter of the term of
		the lease or the useful life of the asset
		i.	Impairment of long lived assets and intangible assets subject to amortization:
	Property and equipment and intangible assets subject to amortization are reviewed for impairment in accordance with ASC No. 360, "Accounting for the Impairment or Disposal of Long-Lived Assets," whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the future undiscounted cash flows expected to be generated by the assets. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets.
	Intangible assets acquired in a business combination are recorded at fair value at the date of acquisition. Following initial recognition, intangible assets are carried at cost less any accumulated amortization and any accumulated impairment losses. The useful lives of intangible assets are assessed to be either finite or indefinite. Intangible assets that are not considered to have an indefinite useful life are amortized over their estimated useful lives, which range from 1 to 10 years. Some of the acquired customer arrangements are amortized over their estimated useful lives in proportion to the economic benefits realized. This accounting policy results in accelerated amortization of such customer arrangements as compared to the straight-line method. All other intangible assets are amortized over their estimated useful lives on a straight-line basis.
	During 2011, 2012 and 2013, no impairment losses were recorded.
		j.	Goodwill:
	Goodwill represents the excess of the purchase price in a business combination over the fair value of the net tangible and intangible assets acquired. Under ASC 350, goodwill is not amortized, but rather is subject to an annual impairment test.
	ASC 350 requires goodwill to be tested for impairment at least annually or between annual tests in certain circumstances, and written down when impaired. Goodwill is tested for impairment by comparing the fair value of the reporting unit with its carrying value.
	In September 2011, the Financial Accounting Standards Board, or FASB issued ASU 2011-08, Testing Goodwill for Impairment, codified in ASC 350 "Intangibles - Goodwill and Other". The revised accounting standard update intended to simplify how an entity tests goodwill for impairment. The amendment allows an entity to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. An entity is no longer required to calculate the fair value of a reporting unit unless the entity determines, based on a qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. The Company chose not to adopt the new guidance in 2013.
	In accordance with ASC No. 350 the Company performs an annual impairment test at December 31 each year. The first step, identifying a potential impairment, compares the fair value of the reporting unit with its carrying amount. If the carrying amount exceeds its fair value, the second step would need to be performed; otherwise, no further step is required. The second step, measuring the impairment loss, compares the implied fair value of the goodwill with the carrying amount of the goodwill. Any excess of the goodwill carrying amount over the applied fair value is recognized as an impairment loss, and the carrying value of goodwill is written down to fair value.  During the years ended December 31, 2011, 2012 and 2013, no impairment losses were recorded.
		k.	Revenue recognition:
	The Company and its subsidiaries generate revenues mainly from selling their products and from post-contract customer support, which are sold primarily through distributors and resellers, all of which are considered end-users.
	Revenues from product sales are recognized in accordance with ASC No. 605, "Revenue Recognition" when delivery has occurred, persuasive evidence of an agreement exists, the vendor's fee is fixed or determinable, and collectability is reasonably assured.
	Revenue derived from post-contract customer support, which represents mainly software updates, help desk support, unit replacement or repair, and security update service is recognized ratably over the contract period, which is typically between one year and five years.
	Revenues in arrangements with multiple deliverables are allocated using the relative selling price method. The Company determines the best estimated selling price ("BESP") in multiple-element arrangements as follows:
	VSOE for post-contract customer support is determined based on the price charged when such element is sold separately (renewals). The price may vary in the territories and vertical markets in which the Company conducts business. Price is determined by using a consistent percentage of the Company's product price lists, in the same territories and markets.
	For the product, the Company determines the BESP based on management estimated selling price by considering several external and internal factors including, but not limited to, pricing practices including discounting, margin objectives, and competition. The determination of estimated selling price ("ESP") is made through consultation with and approval of management, taking into consideration the pricing model and go-to-market strategy.
	The Company records a provision for estimated sale returns and stock rotation granted to customers on products in the same period the related revenues are recorded in accordance with ASC No. 605. These estimates are based on historical sales returns, stock rotations and other known factors. Such provisions amounted to $ 1,071 and $ 914 as of December 31, 2012 and 2013, respectively.
	Deferred revenues include unearned amounts received under post-contract customer support, and classified in short and long term based on their contractual term.
		l.	Shipping and Handling:
	Shipping and handling fees charged to the Company's customers are recognized as product revenue in the period shipped and the related costs for providing these services are recorded as a cost of sale.
		m.	Cost of revenues:
	Cost of products is comprised of cost of software and hardware production, manuals, packaging, license fees paid to third parties and amortization of acquired technology.
	Cost of services is comprised of cost of post sale customer support.
		n.	Warranty costs:
	The Company generally provides a one year warranty for all of its products. A provision is recorded for estimated warranty costs at the time revenues are recognized based on the Company's experience. Warranty expenses for the years ended December 31, 2011, 2012 and 2013 were immaterial.
		o.	Research and development expenses:
	Research and development expenses are charged to the statement of income, as incurred.
		p.	Grants:
	Starting 2012 the Company received non-royalty-bearing grants from the Government of Israel for approved research and development projects. These grants are recognized at the time the Company is entitled to such grants on the basis of the costs incurred as provided by the relevant agreement and included as a deduction from research and development expenses.
	Research and development grants deducted from research and development expenses amounted to $ 264 and $ 369 in 2012 and 2013, respectively.
		q.	Accounting for stock-based compensation:
	The Company accounts for stock-based compensation in accordance with ASC No. 718, "Compensation-Stock Compensation". ASC No. 718 requires companies to estimate the fair value of equity-based payment awards on the date of grant using an option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as an expense over the requisite service periods in the Company's consolidated statement of income.
The Company recognizes compensation expenses for the value of its awards based on the accelerated attribution method over the requisite service period of each of the awards, net of estimated forfeitures. ASC No. 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Estimated forfeitures are based on actual historical pre-vesting forfeitures.
ASC No. 718 requires the cash flows resulting from the tax deductions in excess of the compensation costs recognized for those stock options to be classified as financing cash flows.
The Company selected the Black-Scholes-Merton option pricing model to account for the fair value of its stock-options awards with only service conditions and whereas the fair value of the restricted stocks awards is based on the market value of the underlying shares at the date of grant. The option-pricing model requires a number of assumptions, of which the most significant are the expected stock price volatility and the expected option term. Expected volatility was calculated based upon actual historical stock price movements over an historical period equivalent to the option's expected term. The expected option term represents the period of time that options granted are expected to be outstanding. Expected term of options granted is based upon historical experience. The risk-free interest rate is based on the yield from U.S. treasury bonds with an equivalent term. The Company has historically not paid dividends and has no foreseeable plans to pay dividends.
The fair value of the Company's stock options granted to employees, consultants and directors for the years ended December 31, 2011, 2012 and 2013 was estimated using the following weighted average assumptions:
Employees stock option plan:
		Year ended
		December 31,
		2011			2012			2013
Risk free interest rate			0.99	%		0.46	%		0.81	%
Dividend yields			0	%		0	%		0	%
Expected volatility			47	%		47	%		44	%
Weighted average expected term from grant date (in years)			3.79			3.67			3.93
	r.	Income taxes:
The Company accounts for income taxes in accordance with ASC No. 740, "Income Taxes". This statement prescribes the use of the liability method whereby deferred tax assets and liability account balances are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company and its subsidiaries provide a valuation allowance, if necessary, to reduce deferred tax assets to their estimated realizable value if it is more likely than not that a portion or all of the deferred tax assets will not be realized.
Deferred tax liabilities and assets are classified as current or noncurrent based on the classification of the related asset or liability for financial reporting, or according to the expected reversal dates of the specific temporary differences if not related to an asset or liability for financial reporting.
ASC 740 contains a two-step approach to recognizing and measuring a liability for uncertain tax positions. The first step is to evaluate the tax position taken or expected to be taken in a tax return by determining if the weight of available evidence indicates that it is more likely than not that, on an evaluation of the technical merits, the tax position will be sustained on audit, including resolution of any related appeals or litigation processes. The second step is to measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. The Company accrues interest and penalty, if any related to unrecognized tax benefits in its taxes on income.
	s.	Concentrations of credit risks:
Financial instruments that potentially subject the Company and its subsidiaries to concentrations of credit risk consist principally of cash and cash equivalents, bank deposits, available-for-sale marketable securities and trade receivables.
The majority of the Company's and its subsidiaries' cash and cash equivalents and bank deposits are invested in major banks in Israel and the U.S. Deposits in the U.S. may be in excess of insured limits and are not insured in other jurisdictions.  Generally, these cash equivalents may be redeemed upon demand and, therefore management believes that it bears a lower risk. The short term and long term bank deposits are held in financial institutions which management believes are institutions with high credit standing, and accordingly, minimal credit risk from geographic or credit concentration exists with respect to these bank deposits. As of December 31, 2013, 60% of the Company's short-term and long-term bank deposits were deposited in major Israeli banks in Israel which are rated AA+, as determined by the Israeli affiliate of S&P, and 40% were deposited in the U.S. branch of another major Israeli bank which is also rated AA+, as determined by the Israeli affiliate of S&P.
As of December 31, 2013, the maximal contractual duration of any of the Company's bank deposits was 2 years, the weighted average duration of the Company's deposits was 1.8 years, and the weighted average time to maturity was slightly less than a year.
The Company's marketable securities include investments in foreign banks and government debentures and in corporate debentures.  The financial institutions that hold the Company's marketable securities are major U.S. financial institutions, located in the United States. Management believes that, the Company's marketable securities portfolio is a diverse portfolio of highly-rated securities and the Company's investment policy limits the amount the Company may invest in each issuer, and accordingly, minimal credit risk exists from geographic or credit concentration with respect to these securities. As of December 31, 2013, 54% of the Company's marketable securities portfolio was invested in debt securities of financial institutions, 6% in debt securities of governmental institutions and 40% in debt securities of Corporations. No more than 2% of the Company's total investments portfolio was invested in debt securities of one issuer. From geographic prospective, 54% of the Company's marketable securities portfolio was invested in debt securities of U.S. issuers, 26% was invested in debt securities of European issuers and 20% was invested in debt securities of other geographic-located issuers. As of December 31, 2013, 95% of our marketable securities portfolio was rated A- or higher, as determined by S&P, and 5% was rated BBB or BBB+.
The trade receivables of the Company and its subsidiaries are mainly derived from sales to customers located primarily in the United States, Europe, the Middle East, Africa and Asia Pacific. The Company performs ongoing credit evaluations of its customers. An allowance for doubtful accounts is determined with respect to those amounts that the Company has determined to be doubtful of collection. In certain circumstances, the Company may require from its customers letters of credit, other collateral or additional guarantees. Bad debt expenses for the years ended December 31, 2011, 2012 and 2013 were $ 0, $ 0 and $ 200, respectively. Total write offs during 2011, 2012 and 2013 amounted to $ 200, $ 7 and $ 534, respectively.
	t.	Severance pay:
The Company's liability for severance pay for periods prior to April 1, 2007 is calculated pursuant to Israeli severance pay law based on the most recent salary of the employees multiplied by the number of years of employment as of the balance sheet date. The Company recorded as expenses the increase in the severance liability, net of earnings (losses) from the related investment fund. Employees were entitled to one month's salary for each year of employment, or a portion thereof. Until April 1, 2007, the Company's liability was partially funded by monthly payments deposited with insurers; any unfunded amounts would be paid from operating funds and are covered by a provision established by the Company.
The carrying value of the deposited funds for the Company's employees' severance pay for employment periods prior to April 1, 2007 include profits and losses accumulated up to the balance sheet date. The deposited funds may be withdrawn only upon the fulfillment of the obligation pursuant to Israeli severance pay law or labor agreements.
Effective April 1, 2007, the Company's agreements with employees in Israel are in accordance with section 14 of the Severance Pay Law - 1963 which provide that the Company's contributions to severance pay fund shall cover its entire severance obligation with respect to period of employment subsequent to April 1, 2007. Upon termination, the release of the contributed amounts from the fund to the employee shall relieve the Company from any further severance obligation and no additional payments shall be made by the Company to the employee. As a result, the related obligation and amounts deposited on behalf of such obligation are not stated on the balance sheet, as the Company is legally released from severance obligation to employees once the amounts have been deposited, and the Company has no further legal ownership on the amounts deposited. Consequently, effective from April 1, 2007, the Company increased its contribution to the deposited funds to cover the full amount of the employees' salaries.
Severance pay expenses for the years ended December 31, 2011, 2012 and 2013 amounted to approximately $ 2,244, $ 1,945 and $ 2,293, respectively. Accrued severance pay is included in other long term liabilities in the Balance sheet.
	u.	Fair value of financial instruments:
The Company measures its cash equivalents and marketable securities at fair value. Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability. A three-tier fair value hierarchy is established as a basis for considering such assumptions and for inputs used in the valuation methodologies in measuring fair value:
	Level 1	-	Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.
	Level 2	-	Include other inputs that are directly or indirectly observable in the marketplace.
	Level 3	-	Unobservable inputs which are supported by little or no market activity.
	v.	Comprehensive income:
The Company accounts for comprehensive income in accordance with ASC No. 220, "Comprehensive Income."  This statement establishes standards for the reporting and display of comprehensive income and its components in a full set of general purpose financial statements.  Comprehensive income generally represents all changes in stockholders' equity during the period except those resulting from investments by, or distributions to, stockholders.  The Company determined that its only item of other comprehensive income  relate to available for sale marketable securities adjustment.
	w.	Treasury stock:
The Company repurchases its Ordinary shares from time to time on the open market and holds such shares as treasury stock. The Company presents the cost to repurchase treasury stock as a reduction of shareholders' equity. The voting rights attached to treasury stock are revoked.
	x.	Basic and diluted net income per share:
Basic net income per share is computed based on the weighted average number of Ordinary shares outstanding during each period. Diluted net income per share is computed based on the weighted average number of Ordinary shares outstanding during each period, plus dilutive potential Ordinary shares considered outstanding during the period, in accordance with ASC No. 260, "Earnings Per Share".
The total number of shares related to outstanding options excluded from the calculation of diluted income per share as they would have been anti dilutive was 2,263,600, 1,902,200 and 2,735,095 for the years ended December 31, 2011, 2012 and 2013, respectively.
	y.	Business combinations:
The Company accounted for business combination in accordance with ASC No. 805, "Business Combinations". ASC No. 805 requires recognition of assets acquired, liabilities assumed, and any non-controlling interest at the acquisition date, measured at their fair values as of that date. Any excess of the fair value of net assets acquired over purchase price and any subsequent changes in estimated contingencies are to be recorded in earnings. In addition, changes in valuation allowance related to acquired deferred tax assets and in acquired income tax position are to be recognized in earnings.
	z.	Recalssifications:
Certain amounts in prior years' financial statements have been reclassified to conform to the current year's presentation. An amount of $ 5,388 related to uncertain tax positions was reclassified from other payables and accrued expenses to other long-term liabilities. The reclassification had no effect on previously reported net income or shareholders' equity

		b.	Litigation:
		1	In August 2013 the Company reached a settlement with the Israeli Tax Authorities regarding the Company's corporate tax returns from the years 2004, 2005, 2006 and 2008. The settlement amounted to a total payment of NIS 8.3 million ($2.3M). The Company had provisions for the related years in the amount of NIS 6.4 million ($1.8M). The amount in excess (approximately $500) was recorded as an additional tax expense during 2013. During 2013 the ITA began assessment of 2009-2011 tax years.
		2	In November 2011, SNMP Research International, Inc. and SNMP Research, Inc. commenced a lawsuit in the United States Bankruptcy Court for the District of Delaware against Nortel Networks, Inc. (and certain of its affiliates entities), Genband US LLC, GENBAND, Inc., Performance Technologies, Inc., Perftech (PTI) Canada, Avaya, Inc. and Radware, Ltd.  The Company alleges that the Company has infringed certain of SNMP's copyrights, misappropriated certain of SNMP's trade secrets, were unjustly enriched, and converted certain of SNMP's intellectual property. SNMP has asserted that as part of the Company's acquisition of the Layer 4-7 Application Delivery business from Nortel Networks in March 2009, the Company received certain intellectual property of SNMP Research that was embedded in the Layer 4-7 business.The complaint does not specify the amount of damages and requests that such amount be determined at trial.  The Company served with the complaint in Israel in March 2013 and advised SNMP Research that it diligently investigated whether software received from Nortel included SNMP Software, and based on such investigation no SNMP Software was found.
	The Company moved to dismiss the action in May 2013 based on failure of the complaint to plead facts sufficient to state plausible causes of action for which relief can be granted.  Oral argument on the motion was conducted on October 29, 2013.  On December 10, 2013, Chief Judge granted the Company's motion and dismissed the complaint as to the Company. SNMP filed an amended complaint with the same claims on December 27, 2013, but the Company has not yet been served with the amended complaint.  The Company is discussing settlement with SNMP. Draft settlement agreements have been exchanged which impose no liability on the Company. If settlement is not reached and SNMP Research does not voluntarily dismiss the amended complaint against the Company, the Company intends to vigorously defend the litigation, and cannot estimate what impact, if any, the litigation may have on the results of operations, financial condition or cash flows.
		3	On December 23, 2013, Parallel Networks, LLC filed suit in the United States District Court for the District of Delaware, alleging infringement of U.S. Patent relating to the Company's products that offer certain caching and URL re-writing features. The Company denies that it has infringed any valid claims of the asserted patents and has filed counterclaims for a declaration that the Company's products do not infringe and that the patents are invalid.  The Company intends to continue to vigorously oppose Plaintiff's claims as the litigation is still in a preliminary stage,  and cannot estimate what impact, if any, the litigation may have on the results of operations, financial condition or cash flows.
		4	On October 22, 2012, Branch Banking and Trust Co. ("BB&T) filed a third-party complaint in the Eastern District of Texas against Radware Inc., ("Radware") seeking indemnification for patent infringement claims brought by TQP Development LLC ("TQP") against BB&T in the same court.  The complaint alleges that BB&T purchased certain products from Nortel Networks Inc. ("Nortel") and Covelight Systems Inc. and that TQP has alleged that BB&T's use of these products infringes certain TQP patents.  BB&T further alleges that Radware is the successor in interest to Nortel and Covelight and that Radware, has refused to defend and hold BB&T harmless against TQP's allegations in breach of BB&T's agreements and warranties with Nortel and Covelight.  On January 14, 2013, Radware filed an answer and counterclaim denying that Radware has any indemnity obligations to BB&T and seeking declaratory judgment as to each of BB&T's asserted causes of action.  On April 8, 2013, the Court granted BB&T's motion to dismiss its action against Radware without prejudice. On September 6, 2013 TQP moved to dismiss all claims against BB&T.  On January 14, 2014 Magistrate Judge issued an order recommending granting TQP's motion to dismiss.
		5	OnAugust 29, 2013, F5 Networks Inc. ("F5") filed an amended answer and counterclaim in an action brought by the Company against F5 on May 1, 2013 for infringement of three of the Company's patents regarding link load balancing technology.  In its counterclaim, F5 alleged infringement of four F5 patents related to cookie persistence technology.  In particular, while F5 acknowledged that the Company is licensed to each of the F5 patents-in-suit, F5 contends that the Company's AppDirector and Alteon product lines perform unlicensed modes of the patents-in-suit.  F5's counterclaim further alleged trade libel and unfair competition resulting from statements made by the Company asserting that F5 is responsible for certain internet service problems at major banks, including the Bank of America.  On December 6, 2013, the Company filed an answer denying the allegations in F5's counterclaims.  No date has been set for trial in this matter.

SHAREHOLDERS' EQUITY	'
	NOTE 10:-    SHAREHOLDERS' EQUITY
	The Company's shares are listed for trade on the NASDAQ National Market under the symbol "RDWR".
		a.	Rights of shares:
	Ordinary shares:
	The Ordinary shares confer upon the holders the right to receive notice to participate and vote in shareholders meetings of the Company and to receive dividend, if declared.
		b.	Treasury stock:
	In April 2013 the Company's Board of Directors authorized the repurchase of up to an aggregate of $ 40,000 of the Company's Ordinary shares in the open market, subject to normal trading restrictions. During 2013 the Company purchased a total of 536,557 of its Ordinary shares for total consideration of $ 7,902. Total consideration for the purchase of these Ordinary shares was recorded as Treasury shares, at cost, as part of shareholders' equity.
		c.	Dividends:
	Dividends, if any, will be paid in NIS. Dividends paid to shareholders outside Israel may be converted to U.S. dollars on the basis of the exchange rate prevailing at the date of the conversion. The Company does not intend to pay cash dividends in the foreseeable future.
		d.	Stock Option Plans:
	The Company has two stock option plans, the Company's Key Employee Share Incentive Plan (1997) as amended and restated and the Directors and Consultants Option Plan ("the Stock Option Plans"). Under the Stock Option Plans, options may be granted to officers, directors, employees and consultants of the Company or its subsidiaries. The exercise price per share under the Stock Option Plans was generally not less than the market price of an Ordinary share at the date of grant. The options expire between 5.2 years to 6 years from the grant date. The options vest primarily over four years. Each option is exercisable for one Ordinary share. Any options, which are forfeited or not exercised before expiration, become available for future grants.
	Pursuant to the Stock Option Plans, the Company reserved for issuance 24,259,912 Ordinary shares. As of December 31, 2013, an aggregate of 944,274 Ordinary shares of the Company were still available for future grants.
	On February 1, 2010, the Company's Board of Directors adopted an additional addendum to the share option plan allowing the allocation of short term options to grantees who are not residents of Israel or the United States, with a grant price of 90% of the closing market price of the shares on the NASDAQ on the date of grant of a respective option award. As of December 31, 2013, 1,000,000 Ordinary shares have been reserved for option grants under this addendum. As of December 31, 2013, an aggregate of 763,306 Ordinary shares of the Company, under this addendum, were still available for future grants.
	Restricted Shares Units ("RSUs"):
	In addition to granting stock options, since 2013, the Company started to routinely grant Restricted Stock Units ("RSUs") under the 1997 Plans. RSUs vest primarily over a four years period of employment. RSUs that are cancelled or forfeited become available for future grants.
	Employee Stock Purchase Plan ("ESPP"):
	On February 1, 2010 the Company's Board of Directors adopted the 2010 Employee Share Purchase Plan ("ESPP"), which provides for the issuance of a maximum of 2,000,000 Ordinary shares. Pursuant to the ESPP, eligible employees (including only Israeli and United States residents) could have up to 10% of their net income withheld, up to certain maximums, to be used to purchase the Company's Ordinary shares. The ESPP is implemented with overlapping one year Offering Periods, each one consisting of two purchases, once in every six-month period. The price of each Ordinary share purchased under the ESPP is equal to 90% of the closing price for the shares on the respective Offering Date.
	During 2011, employees purchased 136,658 of Ordinary shares at average prices of $ 7.38. During 2013 and 2012, there was no offering under the ESPP.
	The fair value for the year ended December 31, 2011 was estimated using the following weighted average assumptions:
			Year ended
			December 31,
			2011
	Risk free interest rate			0.29	%
	Dividend yields			0	%
	Expected volatility			36	%
	Weighted average expected term from grant date (in years)			0.75
	As of December 31, 2013, 1,744,440 Ordinary shares are available for issuance under future ESPP.
	A summary of employees, consultants and directors option activity under the Company's Stock Option Plans as of December 31, 2013 is as follows:

TAXES ON INCOME	'
	NOTE 12:-	TAXES ON INCOME
		a.	General:
	A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:
			2012				2013
	Beginning balance		$	1,669			$	5,659
	Additions for prior year tax positions			1,216				541
	Decrease related to settlement with tax authorities			-				(1,831	)
	Additions for current year tax positions			2,774				991
	Ending balance		$	5,659			$	5,360
	The Company's Israeli tax returns have been examined for all years including and prior to fiscal 2008, and the Company is no longer subject to audit for these periods (See also Note 9b(1)).
	As of December 31, 2013, the entire amount of the unrecognized tax benefits could affect the Company's income tax provision and the effective tax rate.
	During the years ended December 31, 2013, 2012 and 2011 an amount of $ 541, $ 512 and $ (7), respectively, was added to the unrecognized tax benefits derived from interest and exchange rate differences expenses related to prior years' uncertain tax positions. As of December 31, 2013 and 2012, the Company had accrued interest liability related to uncertain tax positions in the amounts of $ 299 and $ 959 respectively, which is included within income tax accrual on the balance sheets.
	Exchange rate differences are recorded within financial income, net, while interest is recorded within income tax expense.
	The Company's U.S subsidiary files income tax return in the U.S federal jurisdiction. Tax returns have been examined for all years prior to fiscal 2010, and the Company's U.S subsidiary is no longer subject to audit for these periods.
	In 2013 the Company reached a settlement with the Israeli tax authorities ("ITA") with respect to 2004-2008 tax years (refer to note 9b for further details). As a result the Company released the related reserves.
	The Company believes that it has adequately provided for any reasonably foreseeable outcome related to tax audits and settlement. The final tax outcome of its tax audits could be different from that which is reflected in the Company's income tax provisions and accruals. Such differences could have a material effect on the Company's income tax provision and net income in the period in which such determination is made.
		b.	Israeli Taxation:
		1	Foreign Exchange Regulations:
	Commencing in taxable year 2003, the Company has elected to measure its taxable income and file its tax return under the Israeli Income Tax Regulations. Under the Foreign Exchange Regulations the Israeli company is calculating its tax liability in U.S. Dollars according to certain orders. The tax liability, as calculated in U.S. Dollars is translated into NIS according to the exchange rate as of December 31st of each year.
		2	Tax rates:
	Taxable income of the Israeli companies is subject to the Israeli corporate tax at the rate as follows: 2011 - 24%, 2012 - 25%, 2013 - 25%.
	On July 30, 2013 the Israeli Parliament (the Knesset) passed a law which was designated to increase the tax levy in the years 2013 and 2014. Among other, the law increases the Israeli corporate tax rate from 25% to 26.5%, cancels the reduction of corporate tax rate for Preferred Enterprise and commencing January 1, 2014, increases the tax rate to 20% on dividends from sources under the law for the encouragement of capital investment, 1959.
		3	Tax benefits under the Law for the Encouragement of Capital Investments, 1959 ("the Law"):
	Under the amended Law, as amended in April 2005 a company may claim the tax benefits offered by the Investment Law directly in its tax returns, provided that its facilities meet the criteria for tax benefits set out by the Amendment. A company is also granted a right to approach the Israeli Tax Authorities for a pre-ruling regarding their eligibility for benefits under the Amendment.
	The Company's income derived from the Beneficiary Enterprise will be entitled to a tax exemption for a period of two years and to an additional period of five to eight years with reduced tax rates of 10%-25% (based on percentage of foreign ownership).
	Tax benefits are available under the Amendment to production facilities (or other eligible facilities), which are generally required to derive more than 25% of the Company's business income from export. In order to be eligible for the tax benefits, the Amendment states that a company must make an investment in the Beneficiary Enterprise exceeding a minimum amount specified in the law. Such investment may be made over a period of no more than three years ending at the end of the year in which the company requested to have the tax benefits apply to the Beneficiary Enterprise ("the Year of Election"). Where a company requests to have the tax benefits apply to an expansion of existing facilities, then only the expansion will be considered a Beneficiary Enterprise and the company's effective tax rate will be the result of a weighted combination of the applicable rates. In this case, the minimum investment required in order to qualify as a Beneficiary Enterprise is required to exceed a certain percentage of the company's production assets before the expansion. The duration of tax benefits is subject to a limitation of the earlier of 7 to 10 years from the commencement year, or 12 years from the first day of the year of election.
	The Company elected 2009 and 2012 as year of election according to the Law prior to the reform mentioned below.
	In the event of distribution of dividends from tax-exempt income generated under Beneficiary or Approved Enterprise, the amount distributed will be subject to the same reduced corporate tax rate that would have been applied to the Approved Enterprise's and Benefiting  Enterprise's income.
	In addition, as a result of the amendment, tax-exempt income attributed to Benefiting Enterprise, will subject the Company to taxes upon distribution in any manner including complete liquidation.
	Out of the Company's retained earnings as of December 31, 2013, $ 134,956 are tax-exempt attributable to its Benefited Enterprise programs. If such tax-exempt income is distributed in a manner other than upon complete liquidation of the Company, it would be taxed at the corporate tax rate applicable to such profits, and an income tax liability of up to $ 26,991 would be incurred as of December 31, 2013.
	The Company's board of directors has determined that it will not distribute any amounts of its undistributed tax-exempt income as dividend. The Company intends to reinvest its tax-exempt income and not to distribute such income as a dividend. Accordingly, no deferred income taxes have been provided on income attributable to the Company's Approved Enterprise and Benefiting Enterprise programs as the undistributed tax exempt income is essentially permanent by reinvestment.
	In 2012, new legislation amending to the Investment Law was adopted. Under this new legislation, a uniform corporate tax rate will apply to all qualifying income of certain Industrial Companies, as opposed to the current law's incentives, which are limited to income from Approved Enterprises during their benefits period. Under the new law as amended in July 2013, and starting January 1, 2014 the uniform tax rate will be 9% in areas in Israel designated as Development Zone A and 16% elsewhere in Israel.
	Under the transition provisions of the new legislation, the Company may decide to irrevocably implement the new law while waiving benefits provided under the current law or to remain subject to the current law. Changing from the current law to the new law is permitted at any time and must be communicated to the ITA by the end of May (in the relevant year). As of December 31, 2013, the company remained subject to the current law.
	Income from sources other than the "Approved Enterprise" will be subject to the tax at the regular rate.
		c.	Taxes on income are comprised as follows:

	Taxes on income		$	1,290			$	3,958		$	4,008
		d.	Deferred income taxes:
	Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company's and its subsidiaries' deferred tax liabilities and assets are as follows:
			December 31,
			2012				2013
	Carryforward tax losses		$	2,573			$	2,074
	Temporary differences			1,893				4,391
	Intangible assets			344				752
Deferred tax assets before valuation allowance			4,810				7,217
Valuation allowance			(1,225	)			(902	)
Net deferred tax asset			3,585				6,315
Intangible assets, including goodwill			(577	)			(2,172	)
Unrealized gains on marketable securities			(693	)			(433	)
Deferred tax liability			(1,270	)			(2,605	)
Net deferred tax assets		$	2,315			$	3,710
The net  change in the valuation allowance was mainly due to utilization of operating tax losses and other temporary items for which a valuation allowance was provided.
		December 31,
		2012				2013
Domestic:
Non-current deferred tax liability, net		$	(124	)		$	(661	)
Current deferred tax asset, net			466				1,409
			342				748
Foreign:
Non-current deferred tax asset, net			1,070				1,072
Current deferred tax asset, net			903				1,890
			1,973				2,962
		$	2,315			$	3,710
Non-current deferred tax liability, net is included within other long-term liabilities in the balance sheets. Current deferred tax asset, net is included within other current assets and prepaid expenses in the balance sheets. Non-current deferred tax asset, net is included within other assets in the balance sheets.
Deferred taxes are carried directly to equity if the tax relates to equity items.
	e.	Foreign:
The Company's subsidiaries in the U.S. have provided valuation allowance in respect of deferred tax assets resulting from carry forward of net operating loss relating to excess tax deduction from stock options prior to the adoption of ASC 718 on January 1, 2007. ASC No. 718 prohibits recognition of a deferred tax asset for excess tax benefits due to stock option exercises that have not yet been realized through a reduction in income tax payable. Such unrecognized deferred tax benefits will be accounted for as a credit to additional paid-in-capital, if and when realized. The net change in the valuation allowance primarily relates to stock option benefits and was accounted for as a credit to additional paid-in-capital.
Through December 31, 2013, the U.S. subsidiary had a U.S. federal loss carry forward of $ 12,680, which can be carried forward and offset against taxable income up to 20 years, expiring between fiscal 2021 and fiscal 2031. An amount of $ 6,351 of the net operating loss carry-forwards relates to excess tax deductions from stock options.
Utilization of U.S. net operating losses may be subject to substantial annual limitation due to the "change in ownership" provisions of the Internal Revenue Code of 1986 and similar state provisions. The annual limitation may result in the expiration of net operating losses before utilization.
	f.	A reconciliation between the theoretical tax expense, assuming all income is taxed at the statutory tax rate applicable to income of the Company and the actual tax expense as reported in the statement of operations is as follows:
		Year ended
		December 31,
		2011				2012			2013

SIGNIFICANT ACCOUNTING POLICIES [Abstract]	'
Use Of Estimates	'
		a.	Use of estimates:
	The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates, judgments and assumptions. The Company's management believes that the estimates, judgments and assumptions used are reasonable based upon information available at the time they are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
	On an ongoing basis, the Company's management evaluates estimates, including those related to fair values and useful lives of intangible assets, tax assets and liabilities, fair values of stock-based awards, as well as in estimates used in applying the revenue recognition policy related to separation of multiple elements. Such estimates are based on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities.
Financial Statements In United States Dollars	'
		b.	Financial statements in United States dollars:
	A majority of the revenues of the Company and its subsidiaries are denominated in U.S. dollars ("dollar" or "dollars"). In addition, a substantial portion of the Company's and certain of its subsidiaries' costs are denominated in dollars. The Company's management believes that the dollar is the primary currency of the economic environment in which the Company and its subsidiaries operate. Thus, the functional and reporting currency of the Company and its subsidiaries is the dollar. Accordingly, monetary accounts maintained in currencies other than the dollar are re-measured into U.S. dollars in accordance with Accounting Standards Codification ("ASC") No. 830 "Foreign Currency Matters". Changes in currency exchange rates between the Company's functional currency and the currency in which a transaction is denominated are included in the Company's results of operations as financial income (expense) in the period in which the currency exchange rates change.
Principles Of Consolidation	'
		c.	Principles of consolidation:
	The consolidated financial statements include the accounts of the Company and its subsidiaries. Intercompany balances and transactions including profits from intercompany sales not yet realized outside the Group, have been eliminated upon consolidation.
Cash Equivalents	'
		d.	Cash equivalents:
	Cash equivalents are short-term highly liquid investments that are readily convertible to cash with original maturities of three months or less, at acquisition.
Bank Deposits	'
		e.	Bank deposits:
	Bank deposits with maturities of more than three months but less than one year are included in short-term deposits. Such short-term deposits are stated at cost which approximates market values.
	Bank deposits with maturities of more than one year are included in long-term deposits. Deposits as of December 31, 2013 do not have contractual maturities that exceed two years. Such long-term deposits are stated at cost which approximates market values.
Investment In Marketable Securities	'
		f.	Investment in marketable securities:
	The Company accounts for investments in marketable debt securities in accordance with ACS No. 320, "Investments- Debt and equity Securities". Management determines the appropriate classification of its investments in debt securities at the time of purchase and reevaluates such determinations at each balance sheet date.
	The Company classified all of its debt securities as available-for-sale securities. Available-for-sale securities are carried at fair value, with the unrealized gains and losses reported in "accumulated other comprehensive income (loss)" in shareholders' equity. Realized gains and losses on sales of investments are included in financial income, net and are derived using the specific identification method for determining the cost of securities.
	The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization together with interest and dividends on securities are included in financial income, net.
	The Company recognizes an impairment charge when a decline in the fair value of its investments below the cost basis is judged to be other-than-temporary. The factors considered in making such a determination include the duration and severity of the impairment, the reason for the decline in value, the potential recovery period and the Company's intent to sell, including whether it is more likely than not that the Company will be required to sell the investment before recovery of cost basis. For securities that are deemed other-than-temporarily impaired, the amount of impairment recognized in the statement of income (operations) is limited to the amount related to credit losses, while impairment related to other factors is recognized in other comprehensive income. During the years 2011, 2012 and 2013, the Company did not record any other-than-temporary impairment loss with respect to its marketable securities.
Inventories	'
		g.	Inventories:
	Inventories are stated at the lower of cost or market value. Inventory write-off is provided to cover risks arising from slow-moving items, technological obsolescence, excess inventories and discontinued products. Inventory write-off totaled $ 1,205, $ 1,147 and $ 464 in 2011, 2012 and 2013, respectively, and has been included in cost of revenues.
	Cost is determined as follows:
	Raw materials and components - using the "first-in, first-out" method.
	Work-in-progress and finished products - raw materials as above with the addition of subcontracting costs - calculated on the basis of direct subcontractors costs and with direct overhead costs.
Property And Equipment	'
		h.	Property and equipment:
	Property and equipment are stated at cost, net of accumulated depreciation. Depreciation is calculated by the straight-line method over the estimated useful lives of the assets at the following annual rates:
		%
	Computer, peripheral equipment and software	15 - 33 (mainly 33 )
	Office furniture and equipment	6 - 20 (mainly 15)
	Leasehold improvements	Over the shorter of the term of
		the lease or the useful life of the asset
Impairment Of Long Lived Assets And Intangible Assets Subject To Amortization	'
		i.	Impairment of long lived assets and intangible assets subject to amortization:
	Property and equipment and intangible assets subject to amortization are reviewed for impairment in accordance with ASC No. 360, "Accounting for the Impairment or Disposal of Long-Lived Assets," whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the future undiscounted cash flows expected to be generated by the assets. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets.
	Intangible assets acquired in a business combination are recorded at fair value at the date of acquisition. Following initial recognition, intangible assets are carried at cost less any accumulated amortization and any accumulated impairment losses. The useful lives of intangible assets are assessed to be either finite or indefinite. Intangible assets that are not considered to have an indefinite useful life are amortized over their estimated useful lives, which range from 1 to 10 years. Some of the acquired customer arrangements are amortized over their estimated useful lives in proportion to the economic benefits realized. This accounting policy results in accelerated amortization of such customer arrangements as compared to the straight-line method. All other intangible assets are amortized over their estimated useful lives on a straight-line basis.
	During 2011, 2012 and 2013, no impairment losses were recorded.
Goodwill	'
		j.	Goodwill:
	Goodwill represents the excess of the purchase price in a business combination over the fair value of the net tangible and intangible assets acquired. Under ASC 350, goodwill is not amortized, but rather is subject to an annual impairment test.
	ASC 350 requires goodwill to be tested for impairment at least annually or between annual tests in certain circumstances, and written down when impaired. Goodwill is tested for impairment by comparing the fair value of the reporting unit with its carrying value.
	In September 2011, the Financial Accounting Standards Board, or FASB issued ASU 2011-08, Testing Goodwill for Impairment, codified in ASC 350 "Intangibles - Goodwill and Other". The revised accounting standard update intended to simplify how an entity tests goodwill for impairment. The amendment allows an entity to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. An entity is no longer required to calculate the fair value of a reporting unit unless the entity determines, based on a qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. The Company chose not to adopt the new guidance in 2013.
	In accordance with ASC No. 350 the Company performs an annual impairment test at December 31 each year. The first step, identifying a potential impairment, compares the fair value of the reporting unit with its carrying amount. If the carrying amount exceeds its fair value, the second step would need to be performed; otherwise, no further step is required. The second step, measuring the impairment loss, compares the implied fair value of the goodwill with the carrying amount of the goodwill. Any excess of the goodwill carrying amount over the applied fair value is recognized as an impairment loss, and the carrying value of goodwill is written down to fair value.  During the years ended December 31, 2011, 2012 and 2013, no impairment losses were recorded.
Revenue Recognition	'
		k.	Revenue recognition:
	The Company and its subsidiaries generate revenues mainly from selling their products and from post-contract customer support, which are sold primarily through distributors and resellers, all of which are considered end-users.
	Revenues from product sales are recognized in accordance with ASC No. 605, "Revenue Recognition" when delivery has occurred, persuasive evidence of an agreement exists, the vendor's fee is fixed or determinable, and collectability is reasonably assured.
	Revenue derived from post-contract customer support, which represents mainly software updates, help desk support, unit replacement or repair, and security update service is recognized ratably over the contract period, which is typically between one year and five years.
	Revenues in arrangements with multiple deliverables are allocated using the relative selling price method. The Company determines the best estimated selling price ("BESP") in multiple-element arrangements as follows:
	VSOE for post-contract customer support is determined based on the price charged when such element is sold separately (renewals). The price may vary in the territories and vertical markets in which the Company conducts business. Price is determined by using a consistent percentage of the Company's product price lists, in the same territories and markets.
	For the product, the Company determines the BESP based on management estimated selling price by considering several external and internal factors including, but not limited to, pricing practices including discounting, margin objectives, and competition. The determination of estimated selling price ("ESP") is made through consultation with and approval of management, taking into consideration the pricing model and go-to-market strategy.
	The Company records a provision for estimated sale returns and stock rotation granted to customers on products in the same period the related revenues are recorded in accordance with ASC No. 605. These estimates are based on historical sales returns, stock rotations and other known factors. Such provisions amounted to $ 1,071 and $ 914 as of December 31, 2012 and 2013, respectively.
	Deferred revenues include unearned amounts received under post-contract customer support, and classified in short and long term based on their contractual term.
Shipping And Handling	'
		l.	Shipping and Handling:
	Shipping and handling fees charged to the Company's customers are recognized as product revenue in the period shipped and the related costs for providing these services are recorded as a cost of sale.
Cost Of Revenues	'
		m.	Cost of revenues:
	Cost of products is comprised of cost of software and hardware production, manuals, packaging, license fees paid to third parties and amortization of acquired technology.
	Cost of services is comprised of cost of post sale customer support.
Warranty Costs	'
		n.	Warranty costs:
	The Company generally provides a one year warranty for all of its products. A provision is recorded for estimated warranty costs at the time revenues are recognized based on the Company's experience. Warranty expenses for the years ended December 31, 2011, 2012 and 2013 were immaterial.
Research And Development Expenses	'
		o.	Research and development expenses:
	Research and development expenses are charged to the statement of income, as incurred.
Grants	'
		p.	Grants:
	Starting 2012 the Company received non-royalty-bearing grants from the Government of Israel for approved research and development projects. These grants are recognized at the time the Company is entitled to such grants on the basis of the costs incurred as provided by the relevant agreement and included as a deduction from research and development expenses.
	Research and development grants deducted from research and development expenses amounted to $ 264 and $ 369 in 2012 and 2013, respectively.
Accounting For Stock-Based Compensation	'
		q.	Accounting for stock-based compensation:
	The Company accounts for stock-based compensation in accordance with ASC No. 718, "Compensation-Stock Compensation". ASC No. 718 requires companies to estimate the fair value of equity-based payment awards on the date of grant using an option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as an expense over the requisite service periods in the Company's consolidated statement of income.
	The Company recognizes compensation expenses for the value of its awards based on the accelerated attribution method over the requisite service period of each of the awards, net of estimated forfeitures. ASC No. 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Estimated forfeitures are based on actual historical pre-vesting forfeitures.
	ASC No. 718 requires the cash flows resulting from the tax deductions in excess of the compensation costs recognized for those stock options to be classified as financing cash flows.
	The Company selected the Black-Scholes-Merton option pricing model to account for the fair value of its stock-options awards with only service conditions and whereas the fair value of the restricted stocks awards is based on the market value of the underlying shares at the date of grant. The option-pricing model requires a number of assumptions, of which the most significant are the expected stock price volatility and the expected option term. Expected volatility was calculated based upon actual historical stock price movements over an historical period equivalent to the option's expected term. The expected option term represents the period of time that options granted are expected to be outstanding. Expected term of options granted is based upon historical experience. The risk-free interest rate is based on the yield from U.S. treasury bonds with an equivalent term. The Company has historically not paid dividends and has no foreseeable plans to pay dividends.
	The fair value of the Company's stock options granted to employees, consultants and directors for the years ended December 31, 2011, 2012 and 2013 was estimated using the following weighted average assumptions:
	Employees stock option plan:
			Year ended
			December 31,
			2011			2012			2013
	Risk free interest rate			0.99	%		0.46	%		0.81	%
	Dividend yields			0	%		0	%		0	%
	Expected volatility			47	%		47	%		44	%
	Weighted average expected term from grant date (in years)			3.79			3.67			3.93
Income Taxes	'
		r.	Income taxes:
	The Company accounts for income taxes in accordance with ASC No. 740, "Income Taxes". This statement prescribes the use of the liability method whereby deferred tax assets and liability account balances are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company and its subsidiaries provide a valuation allowance, if necessary, to reduce deferred tax assets to their estimated realizable value if it is more likely than not that a portion or all of the deferred tax assets will not be realized.
	Deferred tax liabilities and assets are classified as current or noncurrent based on the classification of the related asset or liability for financial reporting, or according to the expected reversal dates of the specific temporary differences if not related to an asset or liability for financial reporting.
	ASC 740 contains a two-step approach to recognizing and measuring a liability for uncertain tax positions. The first step is to evaluate the tax position taken or expected to be taken in a tax return by determining if the weight of available evidence indicates that it is more likely than not that, on an evaluation of the technical merits, the tax position will be sustained on audit, including resolution of any related appeals or litigation processes. The second step is to measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. The Company accrues interest and penalty, if any related to unrecognized tax benefits in its taxes on income.
Concentrations Of Credit Risks	'
		s.	Concentrations of credit risks:
	Financial instruments that potentially subject the Company and its subsidiaries to concentrations of credit risk consist principally of cash and cash equivalents, bank deposits, available-for-sale marketable securities and trade receivables.
	The majority of the Company's and its subsidiaries' cash and cash equivalents and bank deposits are invested in major banks in Israel and the U.S. Deposits in the U.S. may be in excess of insured limits and are not insured in other jurisdictions.  Generally, these cash equivalents may be redeemed upon demand and, therefore management believes that it bears a lower risk. The short term and long term bank deposits are held in financial institutions which management believes are institutions with high credit standing, and accordingly, minimal credit risk from geographic or credit concentration exists with respect to these bank deposits. As of December 31, 2013, 60% of the Company's short-term and long-term bank deposits were deposited in major Israeli banks in Israel which are rated AA+, as determined by the Israeli affiliate of S&P, and 40% were deposited in the U.S. branch of another major Israeli bank which is also rated AA+, as determined by the Israeli affiliate of S&P.
	As of December 31, 2013, the maximal contractual duration of any of the Company's bank deposits was 2 years, the weighted average duration of the Company's deposits was 1.8 years, and the weighted average time to maturity was slightly less than a year.
	The Company's marketable securities include investments in foreign banks and government debentures and in corporate debentures.  The financial institutions that hold the Company's marketable securities are major U.S. financial institutions, located in the United States. Management believes that, the Company's marketable securities portfolio is a diverse portfolio of highly-rated securities and the Company's investment policy limits the amount the Company may invest in each issuer, and accordingly, minimal credit risk exists from geographic or credit concentration with respect to these securities. As of December 31, 2013, 54% of the Company's marketable securities portfolio was invested in debt securities of financial institutions, 6% in debt securities of governmental institutions and 40% in debt securities of Corporations. No more than 2% of the Company's total investments portfolio was invested in debt securities of one issuer. From geographic prospective, 54% of the Company's marketable securities portfolio was invested in debt securities of U.S. issuers, 26% was invested in debt securities of European issuers and 20% was invested in debt securities of other geographic-located issuers. As of December 31, 2013, 95% of our marketable securities portfolio was rated A- or higher, as determined by S&P, and 5% was rated BBB or BBB+.
	The trade receivables of the Company and its subsidiaries are mainly derived from sales to customers located primarily in the United States, Europe, the Middle East, Africa and Asia Pacific. The Company performs ongoing credit evaluations of its customers. An allowance for doubtful accounts is determined with respect to those amounts that the Company has determined to be doubtful of collection. In certain circumstances, the Company may require from its customers letters of credit, other collateral or additional guarantees. Bad debt expenses for the years ended December 31, 2011, 2012 and 2013 were $ 0, $ 0 and $ 200, respectively. Total write offs during 2011, 2012 and 2013 amounted to $ 200, $ 7 and $ 534, respectively.
Severance Pay	'
		t.	Severance pay:
	The Company's liability for severance pay for periods prior to April 1, 2007 is calculated pursuant to Israeli severance pay law based on the most recent salary of the employees multiplied by the number of years of employment as of the balance sheet date. The Company recorded as expenses the increase in the severance liability, net of earnings (losses) from the related investment fund. Employees were entitled to one month's salary for each year of employment, or a portion thereof. Until April 1, 2007, the Company's liability was partially funded by monthly payments deposited with insurers; any unfunded amounts would be paid from operating funds and are covered by a provision established by the Company.
	The carrying value of the deposited funds for the Company's employees' severance pay for employment periods prior to April 1, 2007 include profits and losses accumulated up to the balance sheet date. The deposited funds may be withdrawn only upon the fulfillment of the obligation pursuant to Israeli severance pay law or labor agreements.
	Effective April 1, 2007, the Company's agreements with employees in Israel are in accordance with section 14 of the Severance Pay Law - 1963 which provide that the Company's contributions to severance pay fund shall cover its entire severance obligation with respect to period of employment subsequent to April 1, 2007. Upon termination, the release of the contributed amounts from the fund to the employee shall relieve the Company from any further severance obligation and no additional payments shall be made by the Company to the employee. As a result, the related obligation and amounts deposited on behalf of such obligation are not stated on the balance sheet, as the Company is legally released from severance obligation to employees once the amounts have been deposited, and the Company has no further legal ownership on the amounts deposited. Consequently, effective from April 1, 2007, the Company increased its contribution to the deposited funds to cover the full amount of the employees' salaries.
	Severance pay expenses for the years ended December 31, 2011, 2012 and 2013 amounted to approximately $ 2,244, $ 1,945 and $ 2,293, respectively. Accrued severance pay is included in other long term liabilities in the Balance sheet.
Fair Value Of Financial Instruments	'
		u.	Fair value of financial instruments:
	The Company measures its cash equivalents and marketable securities at fair value. Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability. A three-tier fair value hierarchy is established as a basis for considering such assumptions and for inputs used in the valuation methodologies in measuring fair value:
		Level 1	-	Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.
		Level 2	-	Include other inputs that are directly or indirectly observable in the marketplace.
		Level 3	-	Unobservable inputs which are supported by little or no market activity.
Comprehensive Income	'
		v.	Comprehensive income:
	The Company accounts for comprehensive income in accordance with ASC No. 220, "Comprehensive Income."  This statement establishes standards for the reporting and display of comprehensive income and its components in a full set of general purpose financial statements.  Comprehensive income generally represents all changes in stockholders' equity during the period except those resulting from investments by, or distributions to, stockholders.  The Company determined that its only item of other comprehensive income  relate to available for sale marketable securities adjustment.
Treasury Stock	'
		w.	Treasury stock:
	The Company repurchases its Ordinary shares from time to time on the open market and holds such shares as treasury stock. The Company presents the cost to repurchase treasury stock as a reduction of shareholders' equity. The voting rights attached to treasury stock are revoked.
Basic And Diluted Net Income Per Share	'
		x.	Basic and diluted net income per share:
	Basic net income per share is computed based on the weighted average number of Ordinary shares outstanding during each period. Diluted net income per share is computed based on the weighted average number of Ordinary shares outstanding during each period, plus dilutive potential Ordinary shares considered outstanding during the period, in accordance with ASC No. 260, "Earnings Per Share".
	The total number of shares related to outstanding options excluded from the calculation of diluted income per share as they would have been anti dilutive was 2,263,600, 1,902,200 and 2,735,095 for the years ended December 31, 2011, 2012 and 2013, respectively.
Business combinations	'
		y.	Business combinations:
	The Company accounted for business combination in accordance with ASC No. 805, "Business Combinations". ASC No. 805 requires recognition of assets acquired, liabilities assumed, and any non-controlling interest at the acquisition date, measured at their fair values as of that date. Any excess of the fair value of net assets acquired over purchase price and any subsequent changes in estimated contingencies are to be recorded in earnings. In addition, changes in valuation allowance related to acquired deferred tax assets and in acquired income tax position are to be recognized in earnings.
Reclassifications	'
		z.	Recalssifications:
	Certain amounts in prior years' financial statements have been reclassified to conform to the current year's presentation. An amount of $ 5,388 related to uncertain tax positions was reclassified from other payables and accrued expenses to other long-term liabilities. The reclassification had no effect on previously reported net income or shareholders' equity
