DansGuardian is highly flexible Internet content filtering utility and provides you lots of options for controlling the content. is designed to be completely flexible and allows you to tailor the filtering to your exact needs. It can be as draconian or as unobstructive as you want. The default settings are geared towards what a primary school might want but DansGuardian puts you in control of what you want to block.
It filters using multiple methods. These methods include URL and domain filtering, content phrase filtering, PICS filtering, MIME filtering, file extension filtering, POST limiting.
The content phrase filtering will check for pages that contain profanities and phrases often associated with pornography and other undesirable content. The POST filtering allows you to block or limit web upload. The URL and domain filtering is able to handle huge lists and is significantly faster than squidGuard.
The filtering has configurable domain, user and source ip exception lists. SSL Tunneling is supported.
The configurable logging produces a log in an easy to read forhttp://thepcsecurity.com/wp-admin/post-new.phpmat which has the option to only log the text-based pages, thus significantly reducing redundant information such as every image on a page.

DansGuardian is free for all non-commercial uses.
