What Open Systems CASB is

Open Systems CASB gives organizations visibility into cloud application use and tools to govern cloud environments, including shadow IT. It discovers cloud applications and scores risk profiles for more than 9,000 applications. Administrators can block non-compliant applications, restrict risky operations, set safe-domain and URL exclusions, and customize block messages. The service reports newly emerged unsanctioned applications and keeps activity records for forensic investigations. Application categories combine AI with human review. Risk analysis, policy controls, monitoring, and reporting are managed centrally through the Mission Control portal. CASB is delivered inline and works alongside Open Systems ZTNA, Secure Web Gateway, Firewall, and Email Security in its managed SSE layer. The page says activation can avoid complex reconfiguration, especially for existing Secure Web Gateway customers. Level-3 engineers handle integration and operations 24/7, with monitoring and managed support. Open Systems was founded in Switzerland in 1990 and has been part of Swiss Post since 2024.
