ISLANDIA, N.Y., October 13, 2004 - Computer Associates International, Inc. (NYSE: CA) today announced that it has joined the Network Admission Control (NAC) program and is integrating the Cisco Trust Agent with its industry-leading eTrust PestPatrol Anti-Spyware and eTrust Antivirus solutions. When the products become generally available in November, CA will be the first security software vendor to provide both NAC-compliant virus and spyware protection.

By integrating with the Cisco Trust Agent, CA's eTrust solutions further safeguard enterprise environments by helping ensure that only systems in compliance with corporate security policies can connect to the network - thereby preventing individual non-compliant systems from compromising other critical computing resources.

Network Admission Control is a Cisco-sponsored industry initiative that uses network infrastructure to enforce security policy compliance on all networked resources. Using NAC, organizations can identify noncompliant devices and deny them access, place them in a quarantined area, and/or give them restricted access to computing resources. NAC is part of the Cisco Self-Defending Network strategy to increase network intelligence in order to enable the network to automatically identify, prevent and adapt to security threats.

eTrust Antivirus provides comprehensive virus protection from the perimeter to the PDA, automating administrative tasks and signature updates to ensure continuous, up-to-the-minute protection from emerging malware threats. eTrust PestPatrol Anti-Spyware provides essential additional protection against spyware, adware, denial-of-service attacks and other "backdoor" threats. Together, these two CA solutions provide customers with uniquely comprehensive safeguards against the Internet-borne threats that can destroy data, undermine productivity and wreak havoc with IT departments.

"Protecting customer networks - and the business applications that run on those networks - from non-compliant hosts entering a network is a top priority for Cisco," said Bob Gleichauf, the CTO for Security Technology Group at Cisco. "Computer Associates' involvement in the NAC Program provides our customers with a powerful new way to combat the spread of spyware, viruses and worms across their business infrastructure."

CA will continue working with Cisco to further utilize the NAC framework and related technologies - integrating other eTrust threat management solutions with the framework to implement and automate multiple tiers of security across the enterprise.

"The intelligent, automated enforcement of security policy is essential for IT organizations that have to defend the enterprise against a threat landscape that is growing more rapidly than the resources being allocated to security," said Toby Weiss, senior vice president of eTrust security management at CA. "By working closely with Cisco and our other strategic partners, CA is enabling customers to implement enterprise-wide security measures that provide this essential automation and intelligence."
