I work at a school and the previous IT guy bought a very expensive filter that was not user friendly at all and had to be rebooted often because filtering would randomly stop working. I got tired of it and started researching and testing alternatives.
After looking at various paid filters I came across NxFilter and decided to give it a go. It is very easy to set up and get running. Within 30 minutes or so I had it running on two machines in clustered mode. After testing it for a week with no issues, I deployed it on our network. Ever since then it's been running great and handling hundreds of thousands of requests without a sweat.
