Filtering keywords or tightening categories?

Hello all,

    I have the UTM working and it's filtering content, but it doesn't seem as strict as it could be for what I'm trying to do.  It seems like it would be fine if I wanted to filter for ****ography, but I'm actually trying to filter for "hacking" sites.  I made a new category group for this, adding in everything that I thought would apply for blacklisting, but it still seems like only 20% of sites that I think should be blocked, are.

     Is there any way to add to this so that more sites are blocked?  I know with Dansguardian and things that are similar, you can add phrases that should be blocked, but I don't see anything that resembles this.  It doesn't seem to be an https thing, it just seems like the sites, when looking at the logs, are listed as "content servers" or similar things that I can't outright block, otherwise other things would be blocked.  Any thoughts would be great! Thanks!

Hi, cap, and welcome to the User BB!

only 20% of sites that I think should be blocked, are.

Try TrustedSource - Check Single URL to see how the other sites are categorized. You might list your new category for us so we can check to see if something's missing.

Check the 'Bypass Users' tab in 'Filtering Options'. This allows you to block all content servers yet access ones you want. In Reporting, you can see who has bypassed what blocks and adjust the categorization on the 'Websites' tab.

Another thought is to try blocking PUAs in the Anti-Virus section of the Filter Action.

Cheers - Bob
