Looking for content filtering device / software

Similar to what Barracuda does with this:

I'm looking for a cheaper solution to implement for a friend's office. I'm wondering if any of the Linux firewall variants also do content filtering / spyware / malware / what-have you.

$1500 doesn't seem too bad to me, but he appears to have decided that everything should be free.

Any ideas? Thanks in advance!

Depends on the size of the office, number of computers and what he's trying to filter I suppose... $1500 for two computers would be a little steep, but if it's a big office...

For smaller companies I'd go with opendns (opendns.com) which would filter web content quite a bit. Or you could install K9 software on each computer which would give him control over what kind of sites that people can visit. Then I'd just install a good antivirus program with antispyware.

However, if it's a huge office, this product would definitely work if they got the money for it!

Yeah, I've asked to find out how many PC's he's actually concerned about. I assume none of his partners will want filtering, so a good firewall and then the K9 software or similar on the problematic computers might be enough.
