I don't know how to write this without it sounding like a plug (lol), but it's not. So please don't close-vote it, even if you really want your editor badge. Here goes:
There's this site called av-comparatives that I use and trust to provide me independent antivirus reviews. You probably do, too, actually. While I keep myself somewhat knowledgeable about infosec, my specialties lay elsewhere and it's so useful for me to have something like that as a resource.
I don't know of anything like that for firewalls, and when I go out to find one, I'm accosted with millions, all claiming that one product or another is the best. Cross-referencing them often leads to one or two that I've never heard of. The (I think) fairly obvious conclusion there is that these are all just fake third party review sites set up for marketing purposes.
Unfortunately, I don't have the resilience to wade through such murky waters for so many more hours :P
IMPORTANT: This is NOT an open invitation to fake firewall review sites to post their crap. I will respond appropriately to spam.
I'm looking for legit review sites that you, as security professionals, trust (ie: on par with av-comparatives, which you probably trust too)
