The short answer would be "No". What you described, sounds "reasonable
proof", but why should we believe you? ;) Even if you go through the whole
process of hiring some expensive auditors from the likes of Delloite and
Touche all you can get, at best, is something saying that yes, you are as
secure as possible for your type of organization (from their perspective).
All these reports say that if you make any kind of change to the setup, the
report is no longer valid (for example, applying a hotfix is a change). You
may control the network infrastructure, but how about the code behind the
applications? SQL injection attacks may compromise an application regardless
of the how locked the web server is or if the SQL machine is in the DMZ.
Also, how about DoS attacks?
That being said, as a low cost tool, maby you can still install Linux on a
laptop and perform network scans with scanners like Nessus. You can move
your laptop to all the network segments that are part of the infrastructure
that you described and scan them for known vulnerabilities.
