Scouting report

Released Nmap in Phrack in 1997 and has maintained it ever since, adding OS fingerprinting, service detection and the NSE scripting engine. Runs seclists.org, hosting the Bugtraq and Full Disclosure archives that are the field’s institutional memory, and fought MPAA and studio takedown attempts over the tool. Nmap is the first command most defenders learn.

Curator’s note

Twenty-eight years of one maintainer. The reliability is the achievement.
