Santa Clara, CALIF. — March 11, 2003 - Sanctum, Inc., the established leader in Web application security solutions, today announced that AppShield� 4.0 has won the Network Computing Editor's Choice Award in the Web application firewall category. Network Computing compared the leading Web application firewall vendors in the areas of configuration, overall protection, features and price. As a result of rigorous testing of products from five vendors—Sanctum, KaVaDo, Teros, webScurity and MultiNet—AppShield received the highest ranking on overall Web application layer protection. Network Computing further noted that "AppShield has been around the longest of the products tested, and its maturity is obvious. It has a full complement of features and a flexibility that makes it adaptable to nearly every standard Web environment." (Network Computing, March 5, 2003)

AppShield, available as both standalone software and an appliance, provides a failsafe defense against all application-level breaches. AppShield allows for easy application deployment in a secure environment by intelligently identifying the legitimate requests made of an e-business site and permitting only those actions to take place, enforcing the Web and business logic of the site. Through a secure proxy architecture and centralized Java-based management console, AppShield creates policy across an entire site and maintains application behavior 24/7 without the need for signatures or rules.

"Web application firewalls, like AppShield, allow an administrator to protect against what are otherwise undefendable Web attacks," said Jeff Forristal, lead security developer at Neohapsis and contributing author for Network Computing. "AppShield offered a thorough menu of tools and features which we found to be versatile for most needs. The test results proved that AppShield has the capacity to adequately defend against the common attack types seen on the Internet today."

"Network Computing's product review process is known in the industry as being the most objective and thorough, therefore we are particularly honored to have won this award," said Steve Orrin, CTO of Sanctum. "Earning the honor of the Editor's Choice Award further validates AppShield's battle-tested technology."
