Lockdown Networks to Cease Operations on March 18, 2008

SEATTLE — March 18, 2008 — Lockdown Networks today announced that it is ceasing operations effective March 18, 2008. Due to overall

economic trends and slower than predicted adoption of Network Access Control (NAC) technology, the company was unable to raise

additional sufficient venture capital to continue. Lockdown is contacting customers and partners directly to provide more information.

Certain employees have been retained to oversee the shutdown of the company and entertain offers to Lockdown's intellectual property.

Anyone with questions and inquiries can call 206.285.8080 x110.
