My company is considering making a purchase of the Barracuda Spyware
Firewall 310 appliance which it is hoped will assist us in dealing with the
growing threat of drive-by spyware installs. The cost with all the updates
would be nearly $5000. The question I have is this: is there a similar
solution that runs on linux that we can impliment on our own? I'm thinking
along the lines of (perhaps) SpamAssassin, but for spyware.

If anyone has any ideas, please let me know!

Thanks for reading this far
