What does the PAC file do in the context of FortiSASE?

In the context of FortiSASE, a PAC (Proxy Auto-Configuration) file plays a crucial role in directing web traffic through the FortiSASE proxy. When an endpoint device needs to access the internet, it requires a method to determine which proxy server to use for each web request. The PAC file contains JavaScript code that instructs the browser on how to automatically select the appropriate proxy server based on the URL being accessed.

By configuring the endpoint with this PAC file, organizations can ensure that all web traffic is appropriately routed through the FortiSASE proxy, enabling consistent application of security policies, monitoring, and logging of internet traffic. This ensures that users benefit from enhanced security measures provided by the SASE architecture while maintaining seamless internet access.

In contrast, the other options discuss functionalities that are not directly related to the role of a PAC file. Antivirus definitions and login credentials pertain to different aspects of security and authentication, while establishing a VPN connection focuses on creating a secure communication channel rather than managing proxy settings.
