Nmap provides a number of features for probing computer networks, including host discovery and service and operating system detection. These features are extensible by scripts that provide more advanced service detection,[7] vulnerability detection,[7] and other features. Nmap can adapt to network conditions including latency and congestion during a scan.
Nmap started as a Linux utility[8] and was ported to other systems including Windows, macOS, and BSD.[9] It is most popular on Linux, followed by Windows.[10]
