Automatically block certain Sites during specific times of the day.

For example, you can block Facebook between the hours of 9 AM and 6 PM Monday through Friday.

This feature is very flexible. It allows you to create a list of sites that automatically become blocked at certain times.

It’s totally customizable and you can add multiple sites to this blocklist.

You can also choose to block all sites (A special pre-made category within Site Access Control) but sites covered in your ‘Allowlist’ list will of course still be accessible by users. 

To get started

  1. Navigate to Site Access Control in the GAT Shield console.

  6. Click the arrow next to the listed Block list which in our case will cover facebook.com. A new window will appear:
  7. Enter the following configuration:
    1. We select the scope-users we want to be covered by this Block list
    2. (Optional) Redirect users when they’ve been blocked to another website (Using the “Redirect” field)
    3. (Optional) Show a custom warning message which appears above the website being viewed. The pop-up message will completely cover the current website.
    4. Setup a Time restriction if there is no time restriction (these sites will be blocked while the rule is active).
      The rule will not be active outside the setup time-range. GAT Shield: Automatically Block URL Sites | Site Control 3
