What can be established through the use of PAC files on ZIA?

The use of PAC (Proxy Auto-Config) files on Zscaler Internet Access (ZIA) allows for the establishment of traffic routing rules. PAC files provide a way to determine the appropriate proxy server for web requests based on the URL being accessed. They contain JavaScript functions that can direct traffic based on various criteria such as the destination domain or IP address.

When a device or browser is configured to use a PAC file, it can dynamically select which traffic to route through ZIA, allowing for more efficient management of web traffic based on predefined rules. This capability helps ensure that requests are sent to the appropriate Zscaler service, facilitating optimized performance and security.

While user authentication levels, security policy enforcement, and data loss prevention strategies are critical components of ZIA, they are generally addressed through other configuration settings within Zscaler rather than being directly established through PAC files. The primary role of PAC files lies in routing traffic effectively to the right resources based on their defined logic.
