Zenmap is the official Nmap Security Scanner GUI. It is a multi-platform, free open source application that provides users with an easy-to-use graphical user interface (GUI) for Nmap. Nmap, or Network Mapper, is the underlying software that is an extremely powerful tool for security auditing, network-attached device discovery, and security reconnaissance. Its primary focus is port scanning, but Nmap is so much more than a port scanner -- it’s a complex security tool that helps you identify operating systems, application/service versions, and vulnerabilities on your network. Nmap's complexity makes the Zenmap program extremely valuable for those who want to get started with security scanning without the long learning curve.
Unlike some GUI tools, Zenmap is not a less flexible tool or less professional tool that is “dumbed down” for those who shun the command line. Sure, it has some “canned” scans that you can select, but you can also enter Nmap commands with options into the Command field for full flexibility and enjoy every aspect of the command-line interface. Zenmap also makes it easy for you to compare scan results, search scan results, and filter hosts.
