What is the role of a cloud access security broker (CASB)?

A cloud access security broker (CASB) serves a critical function in cloud security management by monitoring and enforcing security policies across cloud services. This intermediary sits between the cloud service consumer and the cloud service provider, providing a layer of security that helps organizations protect their sensitive data and comply with regulatory requirements.

One of the primary responsibilities of a CASB is to enforce security policies such as access control, data encryption, and threat detection. They ensure that the organization’s security protocols are upheld when accessing cloud applications, and they can provide visibility into cloud usage and user activity. By doing this, CASBs help organizations manage risks associated with cloud adoption, including data breaches and compliance violations.

In contrast to the other roles mentioned, a CASB does not focus on facilitating data recovery, managing vendor contracts, or handling billing and usage. While these functions might be relevant in a broader context of IT management, they are not the primary focus of a CASB, which is dedicated to overseeing and enforcing security policies in the cloud environment.
