Symptoms

You enabled URL filtering in a protection plan and added a website to Blocked list.

The blocked website opens completely or partially in Google Chrome on the protected machine, while being correctly blocked in other browsers.

Cause

Google Chrome caches a significant amount of diverse data from websites and uses the cache to load (parts of) websites into the browser faster, by that partially or completely bypassing the URL filtering.

Workaround

After adding the specific website to the Blocked list in URL filtering, it is required to clear all Google Chrome browsing data and restart Google Chrome.
