What is Cloud Access Security Broker in Cybersecurity?
Rhymes with 'has-bee'.
A cloud access security broker sits between users and cloud services to enforce security policies. CASBs provide visibility into SaaS usage, detect shadow IT, enforce data loss prevention rules, and manage access controls across cloud applications. They operate in inline (proxy) or API modes depending on the deployment model.
Why Cloud Access Security Broker Matters for Your Cybersecurity Career
Organizations use dozens to hundreds of SaaS applications, and CASBs are the primary tool for maintaining visibility and control over them.
