    We had it... and I was so glad to escape. It really didn't do the job as far as we were concerned. Too much got through.

    For primaries... Completely open source... Linux box (CentOS or Ubuntu) running squid and DansGuardian and set to download latest filter lists off the internet... I may even run Snort on a couple of boxes.

    I have a couple of these boxes in primaries... been running strong for 3+ years, nice simple easy web interface to block or unblock anything.

    One of them still in a Secondary School, Ubuntu server running Squid, DG and Webmin for management. It has 2 network cards one for internet and one for LAN to switch... been running about 3 years with no issues.

    Does much bad stuff get through that list?

    I've never had a problem at all... sometimes it blocks too much but you just add exclusions for domains or whitelists.

    It blocks 9/10 proxy sites too... logging is quite good. You can customize all the block pages etc to what ever you want too.

    Couple more q's if I may - do you authenticate against AD and filter accordingly? Also, what do you do about https? Ta.

    I've used pfsense with dansguardian a couple of times...it's not that hard to set up and works fine with ldap.

    You have to use legacy adapters in Hyper-V for pfsense, though...and you have to up/down the interfaces for them to work properly sometimes.

    Just any old machine with 2 nics you've got lying around would do.
