Why are you making "authoritative" pronouncements about a product you are not familiar with, instead of asking for advice from people who are?
The questions asked were *not* about certifications. That was
*your* response, which does *not* provide a valid answer.That isn't what you've said... and that would be nice back pedaling except...
You just said you don't dispute that it is a firewall, and then again you say that it isn't. Mince weasel words if you like, but such obvious logical contradictions reflect on all of your conclusions.
So you have no actual knowledge about *any* of the devices that the OP asked about. Okay...
I see no reason to trust assertions you are making. You admit to no special knowledge about the specific equipment, and make illogical references to certification of alternate products by one company and not for the other, and then only for high end equipment costing 10 to 100 times as much.
Moreover, your "certification agency" requires a paid contract from the vendor before a product will be evaluated, and certification will be dropped if the contract is not kept current!
It still reduces to the fact that ICSA certification probably does suggest that a given product meets at least minimum standards while a lack of ICSA certification means *absolutely*
*nothing*. Your comments are logically invalid because they have all been based on lack of certification.There are points of interesting significance about the ICSA certifications though, which should not go unnoticed. I mentioned previously the lack of any reference at all to OpenBSD, and that *clearly* restricts the idea that ICSA certification is in any way a broad based definition of what is or is not a viable firewall.
That is a negative inference, but there is at least one positive point that can be inferred too. A simple count shows that ICSA has certified more than 20 devices using the Linux OS, offered by a diverse group of 9 different vendors. No other specific OS is listed with anything like that number of units or vendors.
The obvious conclusion that can be drawn is that non-proprietary Linux solutions provide top quality firewall functionality.
Both Watchguard and Linksys use Linux based firewalls on equipment that has not been certified by ICSA. Some of the high level Watchguard devices using Linux have been certified, while Cisco, owner of Linksys, uses a proprietary OS on high end devices.
