I am looking into content filter solutions for the small business network I run. Currently there is a Cisco PIX 501 firewall in place. I am aware this handles content filtering, but I am wondering if there is anything else out there that handles it better, is easier to use, and/or is better suited for the job. I have looked a little into appliances from Barracuda Networks, and have recently heard about iBoss web filters. Any recommedations/comments about devices from these vendors, or ideas about others?
