Sanctum was a Santa Clara, California-based information technology company focused on application security. Sanctum was credited for inventing the application security space in the mid-'90s with its firewall, AppShield, and scanner, AppScan, when it foresaw the need for better application-layer security for Web environments.
The company released its first product AppShield in summer of 1999.
The company has done an extensive research in application security and applying formal methods to real life software in collaboration with Turing Award winner Professor Amir Penueli. Early research in 1996 and 1997 led to the invention, in parallel to other teams, of CAPTCHA technology, and the application for a US patent for CAPTCHA.
The AppShield product was the first product to inspect incoming Hypertext Transfer Protocol requests and block malicious attacks based on a dynamic policy which was composed by analyzing the outgoing HTML pages.
Later in June 2000 the company introduced AppScan the world's first Web Security Vulnerability Assessment solution. Among the first clients for AppScan were Yahoo!, Bank of America and AT&T.
