Block All Websites in Google Chrome with GAT Shield allows an admin to block a user from any web access and allows them to use only specific sites to be accessed.
First, we can use a special category called “ALL” that allows us to block all site URLs for the users.
We then can create a custom list of sites that will be allowed.
The allow list takes precedence over the blocklist.
Below are instructions for how to enable this special category and block all and how to create a simple allow category to allow specific sites.
Blocklist #
Navigate to Shield – Configuration – Site access control
A new window will be opened.
From the menu on the left select Predefined Categories
In the predefined categories search for the “all” category. This is a special category that will block all URLs for the users.
Click on the + Create rule for this category button (3).
In the Create rule fill in the required information.
- Rule name – enter the name of the rule
- Category – will be “all” as preselected
- Action – select “rule action – Block”
- Optional – to redirect – enter the redirect URL
- Scope – enter the users to be blocked
- Create – click to create the rule
Result: #
Blocking all websites in Chrome will prevent users from accessing any URL.

Now to Allowlist and set up the Only pages the user is allowed to open.
Navigate to Rules and select Allow/Block Sites
When selected a new pop-up window will be displayed.
Select Allow – and enter the scope of users to be affected by the rule.
Enter the website URLs that will be allowed to be opened.
Select “Allow” when the URLs are added
