DansGuardian wins 'Highly Commended' award

Monitored by Pingdom
DansGuardian is an award winning Open Source web content filter which currently runs on Linux, FreeBSD, OpenBSD, NetBSD, Mac OS X, HP-UX, and Solaris. It filters the actual content of pages based on many methods including phrase matching, PICS filtering and URL filtering. It does not purely filter based on a banned list of sites like lesser totally commercial filters.

DansGuardian 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.

If you are running Microsoft Windows then this software is not for you; it is for running on servers. Of course you can run it on a server and filter Windows clients through it but it will not run on Windows itself.

DansGuardian is a true web content filter.

What is 'Content Filtering'?

Your normal web filter such as Cyber Patrol, squidGuard, Net Nanny, etc, has a very large list of bad sites. If you try to go to these sites you will get blocked. I.e. your web access is filtered by web address.

The web is a fast changing place and even large web search engines such as Google or Altavista or Yahoo don't even know of half of it. This makes filtering by web address (URL) difficult as sites change and new ones come up all the time. It is impossible to have comprehensive filtering using just URLs. What is needed is something to check every page you (or your children) ever access for 'bad' subjects such as drugs, profanities, hate, pornography, etc, and disallow it if it's not suitable. This is called 'Content Filtering'.

This is why you need DansGuardian as it makes the web a cleaner, safer, place for you and your children.

As a side effect, DansGuardian also helps maintain freedom of speech by moving the censoring to the choice of the individual rather than imposing a specific ideal on the whole world.
