OpenDNS customers: We're the alternative! If your "concerned" by the March 15, 2012 cutoff date forcing you into an "Enterprise" service plan, we'd like to save you thousands and help make an easy to transition to our software. Please contact us, all you need is a Windows 2003/2008 server (existing domain controller is fine, it doesn’t have to be a separate server) and we'll remotely setup a fully functional demo. We have all the features of OpenDNS, plus many more, but without the re-occurring service fees! Please give us a chance to earn your business; hundreds have already made the switch.
