SANTA CLARA, CALIF. — October 1, 2001 - Sanctum, Inc., the established leader in automated Web application control and security software, today announced that Vigilinx has selected Sanctum's AppScan 2.5™ software, the most comprehensive risk assessment tool available in the market today, to assess its clients' application-level vulnerabilities. Vigilinx, the largest pure-play security company whose client roster includes several Fortune 500 companies, offers a broad selection of security services including security consulting, integration, IntelliSHIELD™ security intelligence service, managed security services, emergency response and forensics. Vigilinx will employ AppScan 2.5 to automate the complex manual task of auditing Web applications to ensure that sites are safe from code flaws waiting to be exploited by cybercriminals.

"As more companies realize the expensive damage malicious hacker activity can inflict on their business, they are turning to the security experts," said Bruce Murphy, CEO of Vigilinx. "Because our clients want the assurance that their most sensitive information and data will not be compromised or become the target of the next exploit, Vigilinx has added AppScan 2.5 to our arsenal of security services. We are taking no chances and that's why we chose Sanctum's AppScan™ 2.5 solution. It gives us the flexibility to customize audits for our clients, and produces very accurate results with regard to what vulnerabilities exist - known and unknown - and how to fix them. It is clearly the most effective Web application risk assessment tool on the market today."

Empowering the user with improved efficiency, accuracy and flexibility, Sanctum's AppScan automates the manual task of auditing Web applications for both known and unknown application vulnerabilities and provides expert recommendations for fixing these vulnerabilities with the most up-to-date patches or techniques available. AppScan 2.5 delivers a 500% improvement in audit efficiency over manual audits and takes the human guessing and inconsistency out of Web site risk assessment. AppScan is setting the security standard for application audits across the enterprise.

"According to research by Giga Group, 90 percent of security breaches could be prevented if organizations committed to securing their systems upon initial deployment and regularly audited for vulnerabilities," said Peggy Weigle, CEO of Sanctum, Inc. "With AppScan, Vigilinx will be fully prepared to identify and recommend fixes for clients' application-level vulnerabilities before they're exploited. AppScan's accurate evaluation capabilities and enhanced reporting functions enable Vigilinx security professionals to perform the most efficient audits to secure the last mile of their network—the Web applications themselves—against costly cybercriminal attacks."

In addition to AppScan 2.5, Vigilinx provides integration services to clients implementing Sanctum's flagship product, AppShield 3.1. Sanctum's AppShield� software is the first solution to provide eBusinesses and service providers with continuous, autonomous protection against Web application attacks. Securing Web sites by blocking, logging and alerting administrators to any type of application manipulation through the browser, AppShield enables enterprises to focus developer resources on new products and services rather than debugging and patching existing applications.
