SANTA CLARA, CALIF. — February 2, 2004 — Sanctum, Inc., the established leader in automated Web application security firewall and testing software, today announced that AppShield� 4.5 has earned OPSEC� (Open Platform for Security) certification from Check Point Software Technologies Ltd. (Nasdaq: CHKP), a worldwide leader in securing the Internet. Through this certification, AppShield 4.5 allows for seamless integration with Check Point's market-leading Next Generation� with Application Intelligence� software. AppShield 4.0 was originally certified with Check Point's VPN-1�/FireWall-1� Next Generation� software in March 2003. AppShield supports both of Check Point's OPSEC interfaces, which allow AppShield to block offending IP addresses and log critical security events to Check Point SMART in real time.

A growing number of enterprises rely on Check Point's sophisticated security technology for multi-layered defense systems. This OPSEC integration allows AppShield to relay information about connections it is already blocking back to Check Point's VPN-1/FireWall-1, and use this information to block the connections from attacking other resources behind the firewall. AppShield 4.5 allows fully-protected application segregation within the infrastructure providing granular security settings to each individual application. With version 4.5, OPSEC integration becomes even more vital, ensuring the right actions are applied to the proper applications. This added functionality is an important step in Sanctum's continued commitment to providing its customers with the most current and compatible Internet security technology available.

"As information security needs continue to evolve, Sanctum is committed to providing customers with easy-to-deploy application security and management within multi-layered security infrastructure environments," said Steve Orrin, CTO of Sanctum, Inc.

"Sanctum's continued support and integration enhancements to AppShield 4.5 demonstrate that customers continue to prefer best-of-breed security solutions," said Upesh Patel, director of Business Development for Check Point Software Technologies. "Through OPSEC certification, Sanctum's AppShield 4.5 seamlessly integrates with Check Point's market-leading VPN-1/FireWall-1 Next Generation with Application Intelligence software providing customers consistent security enforcement, and an overall solution that is easier to manage and deploy."
