Just wanted to let you guys know. If you are looking for content filtering and don't have a budget for it opendns.com is the way to go. I have been playing around lately with it and yesterday I was able to implement it at a customers site without any issues. I really like it for ease of use and that is free!
I'll second it for a freebie that actually works. I switched our main company from Websense to the built in filtering in our Sonicwall appliance, but one of the affiliates didn't have the budget for their own solution after we took them off our network. Did a little research on OpenDNS and implemented it about 6 months ago. Works very well.
