The main difference between Squidguard and Dansguardian is that
Squidguard uses whitelists/blacklists and Dansguardian has the ability
to read each page a user requests and scan it for certain words,
phrases, etc., assigns the page a score based on those findings, and
allows/disallows based on that score.
