nmap

Why we included this project

Nmap has been the network mapper that security engineers reach for when they need to know what is actually exposed on a host or a subnet. A single command scans ports, identifies services and operating systems, and runs scripted probes for known vulnerabilities, so you get a working inventory of the network in minutes. Its NSE scripting engine is what pushes it past plain port scanning; teams write their own checks against the service versions their environment actually runs. Being a mature C utility with a stable command-line interface, it drops into existing workflows and CI audit jobs without asking you to adopt a new platform.
