Deploy the Secure Access PAC File for macOS
The Cisco Secure Access secure web gateway (SWG) requires that you deploy a proxy auto-config (PAC) file URL on a user device's browser to successfully reach web resources. If you are behind a firewall, you may also need to deploy the Secure Access's PAC file on the browser so that it points to the correct proxy server. A PAC file is only used with the Secure Access Internet Security.
After an organization's administrator adds bypass domains in Secure Access, the Secure Access PAC file contains the list of configured bypass domains. Web traffic to these domains is not sent to the SWG. For more information, see Manage Internet Security Bypass.
