Explanation A cloud access security broker (CASB) is a technology that can restrict access to internet services to authorized users only and control the actions each user can perform on each service. A CASB is a type of software or service that acts as an intermediary between users and cloud service providers. A CASB can enforce security policies, monitor user activity, detect and prevent data leaks, encrypt data, and provide visibility and auditability of cloud usage.
