                       ION NETWORKS ANNOUNCES PRELIMINARY
                  FISCAL 2001 FIRST QUARTER REVENUE ESTIMATES

JUNE 28, 2000 - PISCATAWAY,  NEW JERSEY - ION Networks, Inc. (NASDAQ:IONN),  THE
PROACTIVE NETWORK  MANAGEMENT COMPANY SM , today announced  preliminary  revenue
estimates for the three months ending June 30, 2000.

       Estimated  revenues  for the  first  quarter  of  fiscal  2001  should be
approximately  $2.0 million,  compared with revenues of $4.9 million recorded in
the first quarter of last year.

       "While we are still in the process of  finalizing  our  revenues  for the
first  quarter,   our  preliminary  review  shows  that  our  revenues  will  be
significantly  lower than  anticipated,"  stated Stephen B. Gray,  President and
Chief  Executive  Officer  of  ION  Networks.   "Contributing  to  the  sluggish
performance in the first quarter were decisions by many of our larger  customers
to delay  purchases,  a shift in the release date for our new PRIISMS Manager TM
from June to an expected second quarter release, and a longer than expected ramp
up period for our new sales personnel that have recently joined the Company."

       In response to market  conditions and internal  growth  initiatives,  the
Company  also  announced   today  it  is   restructuring   its  worldwide  sales
organization,  which will be led by Mr. Gray on an interim basis. "We believe we
have developed a strong product platform that meets the needs of our customers,"
added Mr. Gray.  "Our sales  organization  is being  restructured as part of our
continuing  efforts to provide  the  highest  level of  customer  service and to
enhance the predictability of our quarterly financial performance.

       "While the past few months have presented us with significant challenges,
we remain highly  enthusiastic  regarding the Company's ability to capitalize on
the  attractive  opportunities  created by the rapid  broadband  convergence  of
voice,  data  and  video;  increased   environmental



systems  monitoring;  the  significant  market roll out of optical  transmission
infrastructure  equipment;  and the  mission-critical  role that secure  network
management  and  monitoring  plays  in  the  future  of  network  infrastructure
spending," concluded Mr. Gray.

       ION  Networks is a leading  developer  and  manufacturer  of software and
hardware-based   solutions  for  Internet  security,   application   performance
management as well as network  management and  monitoring  for voice,  video and
