Among the four devices we tested, only one -- the SonicWall NSA E7500 -- provided a significant level of protection against malware, blocking 96 percent of the attacks we threw at it.http://infoworld.com/d/security-central/malware-fighting-firewalls-miss-mark-751 However, I'm most interested in the comment at the bottom of the latter from mememe:
It's too bad you didn't try some of the better alternatives like pfsense. I have used/supported sonicwall and watchguard (from the 700 series up to 6 months ago latest version) and pfsense can easily outperform both. Oh yeah, I almost forgot to mention. pfsense is free/open source. http://www.pfsense.orgIf it were me, I'd give pfsense a try. Some years back FreeBSD was noted as a top pick for a secure OS and even recently it got glowing reviews from the military.
