Addition of Trust Digital Enterprise Mobile Edge™ Security in NAC Program Helps Enable the Highest Level of Enterprise Network Protection

McLean, Virginia — April 27, 2005 — Trust Digital, a leading provider of enterprise mobile security software solutions, today announced that it has joined the Network Admission Control (NAC) program, a Cisco-led industry initiative designed to use the network infrastructure to both enforce endpoint security policy compliance on devices looking for access to networks, and prevent malicious attacks. NAC also supports the Self Defending Network, Cisco's strategy for integrated security systems that help identify, prevent, and adapt to threats.

Trust Digital will integrate its award winning Enterprise Mobile Edge™ Security software with the Cisco Trust Agent, helping to allow IT departments to deny network access to end users who are out of compliance with corporate security policy. Using the Cisco Trust Agent, Trust Digital will provide integrity verification capabilities on Palm, Pocket PC and other handheld devices. This functionality will be available to customers who have NAC-enabled Cisco networking hardware in their environment.

"Cisco is pleased to have Trust Digital participating in this collaborative industry program," said Russell Rice, Director of Product Marketing in the Security Technology Group at Cisco Systems, Inc. "Having Trust Digital mobile security products on board enhances the NAC program, and helps bring an integrated and collaborative approach to endpoint security. This collaboration within the NAC effort will provide IT organizations a strong toolset for helping to defend against a variety of threats including malicious attacks, adware, system intrusion and spyware."

"Our Mobile DNA fingerprinting will bring unprecedented mobile device visibility to a NAC-enabled infrastructure," said Norm Laudermilch, Chief Security Officer, Trust Digital. "Trust Digital and NAC will make admission control for PDA's and Smartphones a reality, allowing the secure use of these devices in the enterprise for the first time."
