DansGuardian


What is DansGuardian?

DansGuardian is an open source content filtering system, developed by a team of programmers, SmoothWallLtd, with the main developer being Daniel Barron, for which the product was named. DansGuardian is a filtering program for Linux, FreeBSD, OpenBSD, NetBSD, Mac OS-X, HP-UX and Solaris that uses Squid. DansGuardian is not for Microsoft users, a fact they explicitly state on the site - rather, DansGuardian is geared towards computer-savvy programmers who wish to use a filtering system that they, themselves, can tweak to their own preferences. Also, DansGuardian is a server based filtering program; while it can be adjusted for a PC-oriented filtering system, it works best through the server. 1 DansGuardian has a very strict license that dictates who must pay to download; if a user is downloading from the DansGuardian website for non-commercial use, then the product is free. Third party members, however, charging for installation, or users downloading for commercial use are charged a fee. 2 The prices start at $89, depending on the size of the server. 3

Features

DansGuardian gives a long list of features to their product, specifying what exactly their system blocks. Some of these features include:

  • Can filter text and HTML for obscene content, meaning content that is racial, sexual, violent, etc.
  • Uses an advance phrase weighting system that can reduce under or over blocking.
  • Can work in a "whitelist" mode, where all sites except ones listed are blocked.
  • Can block or limit web uploading.
  • The filtering, in general, is much faster than other competitive products that appeal to the non-Microsoft community.
  • Can be installed easily because there is no third-party library requirements. 4

Reviews

There are few reviews available for DansGuardian, but it is important to remember that this product is not aimed at the typical Windows user. Rather, this product is targeted towards a computer programmer, or other similarly tech-savvy user who understands coding.
