Ah! That's not what we do (pfew). We do make use of those programs, but
they tend to have false postives and they also miss a lot of interesting
stuff. Also, there's no tools to check design, policies, custom
applications, firewall rules, ... That's all handwork.

Some programs are nessus and saint for general vulnerability scanning.
Ethereal is a good network sniffer. For web vulnerability scans you can
use whisker, nikto and arirang. For port scanning nmap is the tool of
choice. Nice OS scanning also by www.netcraft.com or xprobe.

Handy tools to have are also ngrep, netcat dsniff, mtr, amap,
icmpquery, etc.

You cannot do a good security audit on your own network..

If they run the tools above, they are not necessarily frauds. If the
report they write is basically a nessus output then yes, they're frauds.
If you want to prevent frauds coming in, why not ask the company for a
sample report and see what their modus operandi is?
