Web Content Filter

MDM lets you control the contents that can be viewed by users on the Chrome on managed Chromebooks, using Web Content Filter. Web Content Filter lets you Blocklist or Allowlist URLs as explained below:

  • Allowlisting: Only URLs added in this filter can be viewed by the user on Chrome, while all other URLs are blocklisted(restricted from viewing on the device browser).
  • Blocklisting: URLs added in this filter cannot be viewed by the user on Chrome, while all other URLs are allowlisted(can be viewed on the device browser)

Other than restricting URLs, Web Content Filter also provides the option of creating bookmarks, for allowlisted URLs.

Blocklisted URLs can be still be accessed if the corresponding app is present on the device. For example, even if all Facebook URLs have been restricted, users can still access Facebook, if the app is installed on the device. To prevent this, the apps must be blocklisted as explained here.
