How does Zscaler ensure access to applications is context-aware?

Zscaler ensures access to applications is context-aware primarily through the limitation based on user identity. This approach takes into consideration various aspects of the user's identity, such as their role within the organization, the device they are using, and even the geographical context from which they are accessing the application. By leveraging user identity attributes, Zscaler can enforce granular access controls that guarantee users have appropriate permissions for accessing specific applications or data within the network.

This context-aware access helps organizations to enhance security measures significantly, as it prevents unauthorized access based on dynamic factors. For instance, if a user connects from an unusual location or device, Zscaler can implement additional security checks or restrict access altogether, thus minimizing potential security risks.

The other options do not accurately capture the context-aware approach Zscaler employs. While enforcing network-wide VPN connections can provide secure access, it does not adapt based on the user's context. Providing access regardless of user location lacks the necessary security constraints to ensure that only authorized personnel can access sensitive resources. Lastly, relying on pre-defined password policies does not consider real-time context related to user identity, making it less effective for context-aware access control.
