About Credible Websites Only: Top Level Domain Whitelist
Intended for use with managed browser environments where this functionality would be desired, like a school.
Allows only access to .com .net .org .gov and .edu websites.
Doesn't restrict access to web resources accessed via IP address.
For forced installations in managed environments using Google Workspace, an exceptions list can be implemented by using the blocked hosts list on the app and extensions page.
Born out of a desire to have a top level domain whitelist, but finding out this was not possible with G-Suite tooling as of authorship.
