Open Systems CASB review
A focused CASB for cloud discovery, risk scoring, inline controls, and activity logging.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Open Systems CASB is a cloud access security broker for organizations that need visibility and governance across the applications their users access. It identifies unsanctioned shadow IT, assigns risk scores across more than 9,000 cloud applications, and provides controls for blocking non-compliant applications and restricting risky cloud-app operations. The product is aimed at enterprise organizations, particularly teams prioritizing cloud visibility within the Open Systems SASE environment.
According to the vendor’s pricing details, the published starting price is CHF 4.95 for the Secure Access plan. That plan combines Secure Web Gateway, ZTNA, CASB, Firewall, and Transparent proxy capabilities. The starting price assumes self-service operation and 5,000–10,000 users; lower user counts and managed operating models cost more. There is no free plan. This makes the product most relevant to organizations that can fit those operating and scale assumptions, rather than smaller teams seeking a free entry point.
Its main strength is breadth across discovery, policy, monitoring, and investigation. Administrators can create and enforce cloud-application policies, view usage and data flows in real time, customize block messages, and use activity logs for forensic investigations. Open Systems CASB also integrates with Zero Trust Network Access, Secure Web Gateway, Firewall, and Email Security, with self-service or Open Systems Level-3 engineer operation available. The product does not include DLP controls, so teams that require data-loss prevention should choose a CASB with that capability. Open Systems CASB is a strong fit for cloud application governance and inline enforcement, but a narrower choice for buyers seeking DLP-centered protection or independently verified API controls.
