Santa Clara, CALIF. — March 26, 2003 - Sanctum, Inc., the established leader in automated Web application security firewall and testing software, today announced that AppShield � 4.0 has earned OPSEC � (Open Platform for Security) certification from Check Point Software Technologies Ltd. (Nasdaq: CHKP), the worldwide leader in securing the Internet. Through this certification, AppShield 4.0 allows for seamless integration with Check Point's market-leading VPN-1�/FireWall-1� Next Generation � software. In addition, AppShield 4.0 now supports additional OPSEC interfaces allowing Sanctum to block offending IP addresses and log critical security events to the Check Point Management Server in real time.

A growing number of enterprises rely on Check Point's sophisticated security technology for multi-layered defense systems. The OPSEC integration allows AppShield to relay information about connections it is already blocking back to Check Point VPN-1/FireWall-1, which uses this information to block these same connections from attacking other resources behind the firewall. 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.

"AppShield 4.0 now offers improved OPSEC integration supporting Check Point VPN-1/FireWall-1 technology. As information security needs become more complex and enterprises deploy multiple technologies, Sanctum is committed to providing customers with effortless application security deployment and management within multi-layered security infrastructure environments," said Steve Orrin, CTO of Sanctum.

"Sanctum's continued support and integration enhancements to AppShield 4.0 demonstrate that customers continue to prefer best-of-breed security solutions," said Upesh Patel, group manager, OPSEC Alliance for Check Point Software Technologies. "Through OPSEC certification, Sanctum's AppShield 4.0 seamlessly integrates with Check Point's market-leading VPN-1/FireWall-1 software providing customers consistent security enforcement, and an overall solution that is easier to manage and deploy."
