Sanctum's AppShield provides a highly effective defense against application vulnerabilities. The award-winning application firewall 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, maintaining application behavior 24/7 without the need for signatures or rules. Sanctum's AppScan security testing tool provides accelerated, automated testing of security vulnerabilities. With its patented intelligent validation engine, Sanctum's AppScan product suite covers the widest array of attack variants to test both new and existing infrastructures. By reducing security defects before Web applications are deployed in a live production environment, AppScan enables enterprise users to deploy applications quickly, reduce deployment costs, improve resource allocation, assure compliance and minimize risk.
