Nmap is the industry-standard open-source network scanner for host discovery, port scanning, service/version detection, and OS fingerprinting, extensible via the NSE Lua scripting engine. It includes companion tools like Zenmap (GUI), Ncat, and Ndiff.
Use cases
- scan a network for open ports
- discover live hosts on my subnet
- identify services and versions running on a server
- fingerprint the operating system of a remote host
- run vulnerability detection scripts against targets
- audit firewall rules and network exposure
When to choose
- you need reliable, battle-tested network/port scanning
- you want scriptable scanning via the NSE Lua engine
- you need cross-platform support with a GUI option (Zenmap)
When to avoid
- you need a pure library to embed scanning in your own app
- you want a lightweight single-purpose port checker
- scanning networks you don't own or have permission to test
