CASBs were built to help organizations manage and control SaaS usage.
They sit between users and applications, enforcing policies around access, data movement, and compliance.
That works for governing applications. It doesn’t show how those applications are actually being used.
CASBs rely on API integrations and traffic logs to understand activity across SaaS apps. That provides a record of what happened. It doesn’t capture how it happened.Modern attacks unfold inside the browser session, where credentials are entered, sessions are reused, and access is granted through normal flows. That context never shows up in logs.
Push operates at that layer. It gives security teams real-time visibility and response inside browser sessions, where identity and access are actually used.
