OpenDNS

My good friend, mentor even, Steve Marcinek introduced me to a free service today called OpenDNS (www.opendns.com). The scenario goes something like, you have users on corporate machines browsing to places they shouldn't go while using their broadband cellular cards, how do you restrict this? While several solutions come to mind, OpenDNS fits this scenario quite well. Similar to websense you have the ability to control browsing by selecting levels of filtering, which block categories such as pron, hate, violence, social networking, phishing and malware. Once this list is defined you must verify the source IP that you will be filtering from (or subnet) and then configure the users workstation/notebook to use the OpenDNS server for DNS. While an educated user can rearrange these settings, it could be restricted from within Windows. It' s not a perfect solution but once again, for the cost it's incredible.
