A cloud access security broker (CASB) is designed to discover cloud services being used—including unsanctioned applications classified as Shadow IT—and then provide usage analytics, risk scoring, compliance information, and policy control. Cisco specifically lists cloud-application discovery, usage analytics, and risk scoring as CASB visibility capabilities. Cisco Secure Access documentation also describes reporting application details such as reputation, financial viability, and relevant compliance certifications, which directly matches the requirement. EDR concentrates on endpoint activity and response, Secure Firewall controls network traffic, and a cloud workload protection platform protects workloads such as virtual machines and containers. Those technologies are valuable controls, but they do not supply the requested organization-wide SaaS discovery and service-risk catalog. Therefore, CASB is the correct cross-environment visibility solution. Cisco CASB overview
