What function does Policy Segmentation with ZPA serve in the Zero Trust Exchange?

Policy segmentation with Zscaler Private Access (ZPA) plays a crucial role in the Zero Trust Exchange by enabling secure access to private applications. In a Zero Trust framework, the traditional perimeter-based security model is replaced with a more refined approach that requires verification at every access point, regardless of the user's location.

By using policy segmentation, ZPA can enforce granular security controls that dictate who can access which applications based on user identity, device posture, and other contextual factors. This means that users can access only the applications and data they are authorized to see, significantly reducing the attack surface and minimizing the risk of unauthorized access.

The other options do not align with the primary function of policy segmentation in ZPA. While aggregating data and enhancing broadband speeds are important aspects of network management, they are not central to the purpose of secure application access that policy segmentation provides. Similarly, creating public access points contradicts the Zero Trust principle, which emphasizes restricted access and continuous verification.
