A cloud access security broker gives you visibility into and control over the SaaS applications employees use, including unsanctioned shadow IT and data sharing inside approved apps.
My pickNetskopeNetskope is an SSE platform with a strong heritage in CASB and data protection.
CASB now usually comes as part of a broader security service edge platform that also includes SWG and ZTNA. Compare the app catalog, the quality of data loss prevention, and whether it works inline, by API, or both.
Why it works
Sensitive data increasingly lives in SaaS apps. A CASB shows where that data goes and stops risky sharing.
What to look for
It should discover shadow IT.
It should provide data loss prevention for SaaS apps.
It should support both API and inline modes.
