Interfaces
Around Nmap comes several GUIs for Windows, Unix-like environments, and both. Here are shots of the most usable. Note that only Zenmap is the official GUI for Nmap and therefore it is the only one under active developpement at Insecure.org. Others are somehow left aside or under a low developpement process wich makes them less accurate, specially when it comes to the latests options of Nmap : in most cases they are simply not implemented.
