Richard,
One thing to take a look at would be Security Onion. I use this in concert
with my other security gear as a means by which to analyze all traffic coming
in\out of my network. That analysis drives several follow-on activities such
as Snort tuning, forensics, etc.
Re: wifi, check out Mikrotik. I did an eval about 6 months ago that included
MT, Ubiquity, Dlink, Linksys, etc. - about 5 vends in all. I do agree the
Ubiquity line is solid but it is a bit costly when compared to some other
options such as MT. The latter is far and away the best value especially when
considering their wireless performance. I need to also state there is a bit of
a learning curve there but once you dig in and get the hang of it, it’s not an
issue at all. MT devices also have have a very comprehensive feature set.
Let me know if you have any other questions re: this stuff...
