gdOfficeGuardian
Office Guardian is an add-on module for the gdOfficeProxy server.
Office Proxy Guardian 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 gdOfficeGuardian puts you in control of what you want to block.
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 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 gdOfficeGuardian as it makes the web a cleaner, safer, place for you and your staff/children. As a side effect, gdOfficeGuardian 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.
