Hi there..

A client of mine recently received a proposal from XYZ company for a Perimeter Security Analysis Report.
After reading through the proposal myself, it's basically just a WAY
glorified firewall penetration test and report which they are asking a

bargain basement price of close to $15k for!

My question is, are their any "good" recommended hacker type of tools
there, IE. Gateway sniffers, port scanners, and reporting capability programs out there I could purchase/download to perform a thorough
external test of their firewall myself?
