What Open Systems CASB is
Open Systems CASB is a paid, web-based cloud access security service for discovering cloud applications, scoring their risks, and enforcing policies around cloud use and shadow IT. It profiles more than 9,000 applications and lets administrators block non-compliant apps, restrict risky operations, define safe-domain and URL exclusions, and customize block messages. The service reports newly appearing unsanctioned applications and keeps detailed activity records for forensic investigations. Application categorization combines artificial intelligence with human review. Mission Control centralizes risk analysis, policies, monitoring, and reporting. CASB works with Open Systems ZTNA, Secure Web Gateway, Firewall, and Email Security in the managed SSE layer. Deployment is inline, and the maker describes rapid activation without complex reconfiguration, especially for existing Secure Web Gateway customers. Level-3 engineers provide integration and operations support around the clock.
