Network-1 Retains Alliance Advisors to Initiate a Proactive Investor Relations Program

NEW YORK, March 9 -- Network-1 Security Solutions, Inc. (OTC Bulletin Board: NSSI.OB), today announced that it has retained Alliance Advisors, LLC, an affiliate of Hayden Communications, to initiate a proactive and targeted investor relations campaign. Alan Sheinwald, President of Alliance Advisors, and his team will be advising the Company in all facets of a proactive investor communications plan including proper positioning of the corporate message, creation of press releases and presentation materials, and the development of long-term investor relationships by increasing the awareness of the Network-1 investment opportunity to the appropriate members of the professional investment community.

The Company is currently involved in maximizing the value of its intellectual property portfolio and is focusing its efforts on licensing its Remote Power Patent (U.S. Patent No. 6,218,930). The 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 power network connected devices including, among others, VoIP phones, wireless LAN access points and IP network cameras.

"After careful review, we selected Alliance Advisors to ensure that the investment community is kept informed of our progress in the development of our licensing and enforcement activities related to the Remote Power Patent," commented Corey M. Horowitz, Chairman and CEO of Network-1. "The recent settlement of our litigation with PowerDsine, the PoE market leader, combined with the progress of our litigation in the Eastern District of Texas against D-Link Systems, Inc. and its corporate parent, D-Link Corporation of Taiwan, are important steps toward our goal of realizing the full potential underlying the Remote Power Patent licensing opportunities. "

Mr. Sheinwald commented, "Network-1 continues to execute their plan while achieving key milestones in connection with its goal of industry wide licensing of the Remote Power Patent. The importance and intrinsic value of intellectual property is becoming more evident on a daily basis and the timing is right to raise the level of awareness of Network-1's compelling business plan. The Power over Ethernet industry is growing very quickly and we will work diligently to properly articulate to the investment community the varied licensing opportunities available to Network-1."
