Using the admin console / Getting started

Deploy: Group Policy (.reg)

One registry file that installs the extension in Chrome and Edge and connects it to your console, machine-wide.

Replace the enrolment key with yours, from the Browsers page.
Add the values to a Group Policy Object under Computer Configuration, Preferences, Windows Settings, Registry, or import the file on a reference computer and use the Registry Wizard.
Link the object to the computers to protect.
