While I have to agree with the auditor when he says that blocking Spam
and viruses and etc at the perimeter is important, I can't say that you
couldn't do something similar with what you currently have. I'm kind of
iffy on using the all-in-one firewall solutions, but that's just me. I
know of quite a few companies that use them and haven't had any
problems. I can just see trouble coming down the road...
If I were in your shoes I'd investigate solutions (open source?) that
could be implemented to help step up your security. I'd shy away from
buying what everyone else is buying simply because that puts your
network at risk. If a hacker knows how to bypass the most popular
firewall (and I have to say that SonicWall has to be one of them) then
s/he is more likely to start attempting attacks on multiple networks
using that knowledge.
Just my 2-cents worth (which is about what it is worth).
