Zenmap is an Nmap frontend. It is meant to be useful for advanced users and to make Nmap easy to use by beginners.
The purpose of Zenmap is not to replace Nmap, but to make Nmap more useful. Nmap has literally hundreds of options, which can be daunting for beginners. Zenmap’s interface is designed to always show the command that will be run, whether it comes from a profile or was built up by choosing options from a menu.
Zenmap was originally derived from Umit, an Nmap GUI created as part of the Google Summer of Code.
