The function of cloud access security brokers (CASB) is to serve as an intermediary that provides security and management of cloud services. CASBs help organizations gain visibility into cloud application usage and enforce security policies. They address concerns related to data security, compliance, and intrusions by monitoring activities and implementing protections. CASBs facilitate a safer adoption of cloud technologies by enabling identity management, encryption, and threat detection. By doing so, they bridge the gap between on-premises infrastructure and the cloud.
