                                                                    ------------

FOR IMMEDIATE RELEASE

COREY M. HOROWITZ, CHAIRMAN AND CEO
NETWORK-1 SECURITY SOLUTIONS, INC.
212-829-5770

                     NETWORK-1 REPORTS THIRD QUARTER RESULTS

            NEW YORK, November 15, 2004--Network-1 Security Solutions, Inc.
(OTC: NSSI:OB) today announced financial results for the third quarter ended
September 30, 2004.

            Network-1 reported a net loss from operations for the third quarter
ended September 30, 2004 of $(280,000), or $(0.02) per share, compared with a
net loss from operations of $(215,000) $.03 per share for the quarter ended
September 30, 2003. Network-1 reported an operating loss for the first nine
months of 2004 of $(862,000), or $(0.06) per share, compared with an operating
loss of $(635,000), or $(0.03) per share, for the first nine months of 2003. The
Company incurred a net loss of $(861,000) for the nine months ended September
30, 2004, compared to a net loss of $(211,000) for the nine months ended
September 30, 2003, which included a gain of $415,000 on the sale of its
software product line and related intellectual property to an unaffiliated third
party.

            Network-1 did not have revenues for the third quarter or nine months
ended September 30, 2004. Revenues during the comparable periods in 2003 were
related to the recognition of deferred revenue and amortization of deferred
maintenance revenues relating to the Company's software product line which was
discontinued in December 2002.

            In November 2003, Network-1 commenced a new business consisting of
the acquisition, development, licensing and protection of its intellectual
property which currently consists of a portfolio of telecommunications and data
networking patents. In February 2004, the Company initiated its licensing
efforts relating to its patent (U.S. Patent No. 6,218,930) covering the remote
delivery of power over Ethernet cables (the "Remote Power Patent").

            The Company's Remote Power Patent relates to, among other things,
several key technologies underlying the IEEE 802.3af Power Over Ethernet (PoE)
standard that was approved on June 13, 2003 by the Institute of Electrical and
Electronic Engineers (IEEE) (the Standard). The Standard governs the delivery of
power over Ethernet cables in order to remotely power network connected devices.

            The Company has commenced a program offering licensing opportunities
to those companies Network-1 believes would benefit from access to the
technologies covered by the Remote Power Patent, including manufacturers of
wireless switches, wireless access points, RFID card readers, VOIP telephones,
enterprise LAN switches and network cameras, all of whom the Company believes
would benefit from obtaining a license to the Remote Power Patent.

            As previously announced, on March 31, 2004, PowerDsine, Inc.
commenced an action against the Company in the United District Court, Southern
District of New York (Civil Action No. 04 CV 2502) seeking a declaratory
judgment that the Company's patent (US. Patent No. 6,218,930) covering the
remote delivery of power over Ethernet cables (the Remote Power Patent) is
invalid and is not infringed by PowerDsine and/or its customers. PowerDsine is
the technology leader in the fast-growing PoE marketplace. The Company believes
its Remote Power Patent is valid and has meritorious defenses to the action. The
Company and PowerDsine are engaged in settlement discussions in an effort to
resolve the litigation. In the event the settlement discussions are not
successful, the Company intends to vigorously defend the lawsuit and take
whatever actions are necessary to protect its intellectual property. In the
event, however, that the Court granted the declaratory judgment and the patent
was determined to be invalid, such a determination would have a material adverse
effect on the Company.

            Cash and cash equivalents were $333,000 at September 30, 2004.
Management believes that based upon its current cash position, Network-1 will
have sufficient capital to fund its operations through January 2005, although
there is no assurance that such funds will not be expended prior thereto.
Network-1 is currently seeking financing necessary to continue its operations.
