ISE posture check for Browser proxy

Greetings Experts,

ISE 2.1

I have a customer who is inquiring regarding posture check for browser proxy settings. So far looking at the built-in posture conditions I have not come across a condition to check proxy settings of FireFox, Chrome or IE.

While doing further research on Windows Registry conditions, I found the followings (see below) in the Windows registry which is added in Registry table when IE has proxy settings with a ProxyServer enable. I have attached the registry settings which indicates ProxyServer Value. However, I do not see any option / registry settings for FF or Chrome.

Could you please let me know if there is a way to posture check of proxy settings on FF, IE and chrome browser?

Thank you very much for your time and attention.

For Firefox, you may have to do file remediation with this settings:

File: "%APPDATA%\..\Local\Mozilla\Firefox\Profiles\*.default\prefs.js

"network.proxy.http", “173.36.224.108”

"network.proxy.http_port", 80

By default Chrome uses IE settings I believe. So the registry check should cover both IE and Chrome.
