The Arsenal
A catalog of 94 real-world security tools across 11 categories — recon, web, exploitation, cracking, forensics, post-exploit, wireless, blue team. Each entry: what it does, who uses it, the commands you'll actually type.
Nmap
/en-map/
Nmap (Network Mapper) is the most widely-deployed network discovery and security auditing tool. Implements SYN, connect, UDP, ACK, and stealth scans plus OS fingerprinting, version detection, and the Nmap Scripting Engine (NSE) with 600+ NSE scripts. Created by Gordon 'Fyodor' Lyon in 1997 and continuously maintained.
