Simple Active-Directory content filter

Greetings,

I have been looking for a suitable content filter to offer to my customers for a while now.

I have looked into smoothwall, barracuda, dansguardian, and various routers "built-in" filters.


What I'm really looking for at the moment is something that I can install on every computer on the network, that will provide the following;

• Block Internet Access
• Don't block internet access
• Block internet access if site is on a "banned" list

And it will do all of those, by user, not by computer.



All of the ones out there seem to be far too fancy.

I don't mind doing it through group policy either, but I am dealing with large networks in some instances where adding in a proxy to IE won't work, because they have chrome/mozilla/something else installed.



Hmm!
