Here is a link to the Insecure.org site: Top 75 Security ToolsIn May of 2003, I conducted a survey of Nmap users from the nmap-hackers mailing list to determine their favorite security tools. Each respondent could list up to 8. This was a followup to the highly successful June 2000 Top 50 list. An astounding 1854 people responded in '03, and their recommendations were so impressive that I have expanded the list to 75 tools! Anyone in the security field would be well advised to go over the list and investigate tools they are unfamiliar with. I discovered several powerful new tools this way. I also plan to point newbies to this page whenever they write me saying "I do not know where to start".
I plan to go through and add any that I have missed to my Free Tools site.
