Chrome Login Control Events in GAT Shield #
GAT Shield is an extension deployed on users’ Chrome browsers. It allows the Google Workspace Admins to control the login activity of the end-users and manage the users’ browsing activity while logged in the Chrome browser.
How to configure the Login Control module. #
To set up Login Control, navigate to GAT Shield > Configuration > Login Control
Set up the fields as per your requirements and then click Save.
Note that it may take a while for settings to propagate to extensions.

FAQ #
Q1: Will enabling Login Control restrictions completely prevent users from browsing the internet or logging into their devices?
A1: No. The Login Control module only blocks access to Google-related pages (with the exception of YouTube), redirecting the end-user to a dedicated GAT+ block page. It does not prevent users from logging into their physical devices or conducting other non-Google browsing activities.
Q2: How should network addresses be formatted when restricting access to specific Public IPs?
A2: When configuring Public IPs, you must use IPv4 addresses only. You can enter direct addresses (e.g., 72.14.0.154) or network addresses (e.g., 64.233.187.99/8). Note that all network addresses must end with a CIDR notation. Leaving this list empty will allow users to log in from any network.
