How does Zscaler facilitate secure access to SaaS applications?

Zscaler facilitates secure access to SaaS applications primarily by providing contextual security and ensuring compliance with organizational policies. This approach allows Zscaler to analyze user behavior, device posture, and other contextual factors in real-time to make informed decisions about access control.

By evaluating context such as user identity, location, device security, and the sensitivity of the information being accessed, Zscaler can apply the right security measures and enforce compliance effectively. This not only enhances security for SaaS applications but also supports a seamless user experience by allowing legitimate users access without unnecessary friction.
