SANTA CLARA, CALIF. — December 17, 2001 - Sanctum, Inc., the established leader in Web application security software, today announced a partnership with Articon-Integralis AG (Neuer Markt: AAGN), the European market leader in IT security solutions. Under the terms of the agreement, Allasso, the channel-focused company of Articon-Integralis, will distribute both Sanctum products, AppScan and AppShield, throughout Europe. Through their extensive reseller base, Allasso will provide enterprises with Sanctum's solutions to detect and defend against all types of Web application attacks, providing comprehensive protection of critical corporate digital assets and intellectual property.

"Sanctum is developing the world's leading Web application security solutions to help protect companies from browser-launched cybercrime," said Peggy Weigle, CEO of Sanctum, Inc. "With a combined offensive and defensive Web application security solution, corporations can be confident that personal and corporate data cannot be accessed or compromised by a malicious hacker. Through Sanctum's relationship with Articon-Integralis and their subsidiaries, we're building on our current U.S. and Asian presence, now making significant strides in the European market to ensure organizations around the world can benefit from Sanctum's proven technology."

Integralis, the security integration company of Articon-Integralis will distribute AppScan™ and AppShield™ software to its European customer base through its direct sales force. "It is absolutely critical for any company with an e-business presence to deploy a Web application security solution," said Ian Calcutt, Articon-Integralis CEO. "Unlike most security products, Sanctum uses a patented intelligence engine that is policy-based, rather than rules-based. This means AppShield and AppScan can recognize and prevent unauthorized activity for both known and unknown attacks, ensuring comprehensive protection from server-based worms, e-shoplifting, and any other cybercrime involving application manipulation."

AppScan, the most powerful vulnerability assessment tool for Web applications, offers the efficiency, accuracy and flexibility needed to extend Internet security audits through all phases of the application lifecycle. AppScan offers a 500% improvement in efficiency over manual auditing techniques. AppShield is the industry's leading automatic Web application firewall that provides comprehensive, automatic protection against all types of Web application attacks including server-based worms, by monitoring for correct use of the application, blocking the attacker's unauthorized actions, logging IP information and alerting administrators to all attack attempts.
