What is a cloud access security broker (CASB)?

CASB acts as a security gatekeeper between you (the users) and the cloud services, enforcing policies, monitoring behavior and securing data in real time. It checks everything going in and out to make sure it’s safe. It helps organizations monitor and manage cloud application usage, ensuring data security, and compliance. It’s designed for SaaS, PaaS, and Iaas platforms, offering granular control over data and user activities.  

Four pillars of strong CASB are visibility, compliance, data security, and threat protection working together to create safer, controlled cloud environments. CASB also helps enterprises meet compliance requirements like GDPR, HIPAA, by generating audit logs and providing detailed reporting across cloud environments.
