Fyodor asked users from the
nmap-hackers mailing list to share their favorite tools, and

3,243 people responded. This allowed him to expand the list to 100 tools, and even subdivide them into categories. Anyone in the security field would be well advised to go over the list and investigate tools they are unfamiliar with. You will discover several powerful new tools this way. Any newbie, not knowing where to start should go to
this site.
