Another good way is to search job listings that deal with the company with
Online Job postings.. You can get a lot of information just from that
including such things as Firewall makes, models as well as their internal
architectures / systems.

Subject: Re: Fingerprinting Firewall
One of the best way I have found to find out the type of firewall(s)
used is through the company's HR site, which sometimes has a completing
listing on firewalls, IDS, protocols, applications, and MUCH more.
When this does not work I also check firewall mailing list for
@targetcompany.com to see if anyone has posted.
