Answer : Hardware web filters similar to the barracuda 410 webfilter?

I use 8e6 Technologies - that's pretty much the only web content filter I've ever used.  8e6 basically has 2 interfaces - 1 for passive scanning and the other for blocking.
Basically you need to configure a spanned port or put a network tap on your gateway (inside interface of your firewall or router).  Filters are customizable......  It does checks against active directory users (make sure that their web viewing is allowed for their group), you can do filters by IP, MAC, Users.

I've also heard websense is good too.
