Rogue browser extensions are growing as a source of information leakage and cookie stealing.
In a corporate environment it is best practice to take a whitelist approach to browser extensions. Luckily Intune has an inbuild Administrative Template setting to block all browser extensions except those that are explicitly allowed.
-
Use an existing Administrative template profile or create a new profile by going to Devices > Configuration Profiles > Create profile > Platform (Windows 10 and later) > Profile type Templates > Administrative Templates
-
Search for a setting called Control which extensions cannot be installed. Device or User targeted depends on your specific scenario. I prefer User targeted.
-
Set to Enabled with an Extension ID of * to block all extensions.
