Manage Umbrella's PAC File

When configuring Umbrella's secure web gateway (SWG), you have several choices as to how you can send web traffic to Umbrella. One of those choices is to integrate a proxy auto-config (PAC) file URL for the browser you will be using to reach destinations. Once integrated into your system, all traffic through that browser is redirected to Umbrella's secure web proxy.

Note: PAC file downloads and usage are limited to fixed networks registered in Umbrella. PAC files are not supported for roaming computers or other connection mechanisms.

What's a PAC file?

A proxy auto-config (PAC) file is used to tell a browser which proxy server it must use to fetch a URL.

For the most part, integrating Umbrella's PAC file into your system so that all browser-based traffic is proxied is a simple cut and paste procedure. Copy the PAC file URL from Umbrella and paste it into your browser. There may, however, be occasions when you are required to customize the PAC file before integrating it into your system. For more information about deploying and customizing a PAC file, see:

Note: Microsoft has deprecated PAC file support for the file:// and ftp:// protocols in Windows 10 on Edge and Internet Explorer. Hosting the PAC file on the local machine will not work on these browsers. For more information, see Windows 10 does not read a PAC file referenced by a file protocol.
