On a network of say 12 computers what's the best way to stop access to websites such as facebook or adult sites.?
We paid for a firewall a few years ago and that does a decent job. However, it's pretty easy to bypass that if someone wanted to by a simple google search.
Is there a cost effective way to block these sites to safeguard our IT infrastructure?
I looked at a product called smoothwall a few years ago but that looked to be quite expensive for what we wanted.
Any advice would be appreciated.
