CASB

A Cloud Access Security Broker (CASB) is a security tool that acts as a gatekeeper between an organization’s users and the cloud services they access. It helps companies monitor, control, and protect data as it moves to and from cloud applications like email, file storage, and collaboration tools. CASBs provide visibility into cloud activity, enforce security policies, and prevent threats such as data leaks or unauthorized access. Essentially, they ensure that cloud usage aligns with security requirements, maintaining data safety without hindering productivity.
