Installing the Extensions
GoGuardian can filter and monitor any user accounts that have the extensions installed. For this reason, it's important to be deliberate about which OUs are selected during the installation process.
As Chrome policies are automatically inherited from parent OUs, installing the extensions at the domain level will push the extensions out to all users in your domain. You may want to consider installing the extension in OUs that only contain student accounts and omit teacher or staff OUs during the installation process to avoid any unintentional filtering or monitoring.
Additionally, when installing the extensions, ensure that OUs containing user accounts are selected, rather than OUs containing devices. Installing the extensions in OUs that only contain devices will have no effect.
Apps & Extensions
After installing your two custom GoGuardian extensions, GoGuardian recommends the following settings to be configured:
Policy: Allow users to install other apps & extensions
Value: Block all other apps & extensions
Description: Some third-party apps and extensions can be used to bypass GoGuardian. This will prevent your users from installing unapproved apps and extensions from the Chrome Web Store. Ensure that your GoGuardian extensions and any approved apps are added to the "Allowed Apps and Extensions" section. GoGuardian can only filter apps and extensions installed from the Chrome Web Store
Policy: Allowed Types of Apps and Extensions (Click the Gear icon on the right)
Value: Extension - Must be Checked
Description: Disabling extensions will prevent your GoGuardian extensions from being pushed out to your users. Other types of apps and extensions are optional.

Description: Both GoGuardian extensions require the following permissions, so please ensure the following are not blocked/checked:
- detect idle
- memory metadata
- web requests

- native messaging
This section can be skipped if not configured.
