About Nmap
Nmap scans a network and reports which hosts respond, which ports are open, which service and version is behind each one, and often which operating system the host is running. The Nmap Scripting Engine extends that with hundreds of Lua scripts for deeper probing, and a graphical front end called Zenmap ships alongside it.
It is not open source in the usual sense. Nmap is released under the Nmap Public Source License, a custom licence based on but not compatible with GPLv2, which permits free use by end users while requiring a commercial licence for companies that want to redistribute Nmap technology inside their own products.
Strengths
- Host discovery, port scanning, service and version detection and OS fingerprinting in one tool
- The Nmap Scripting Engine adds hundreds of Lua scripts for specific checks
- Installers for Windows, macOS and Linux, plus the Zenmap graphical front end
- Documentation that is genuinely a reference book, not a man page stub
Limitations
- The licence is custom, not OSI-approved, and is incompatible with GPLv2
- Companies redistributing Nmap in their own products need a commercial OEM licence
- Scanning networks you do not own or have permission to test can be unlawful
- Windows scanning depends on Npcap, which has its own licence terms
