Zencat
by Shinnok for Nmap Security Scanner
Zencat is a GUI to Ncat, the Nmap equivalent of the popular swiss army knife of network tools, netcat. The purpose of Zencat is to facilitate raw human interaction(either manual or semi-automatic) with network sockets by building an extended usability layer above the Ncat backend. Zencat will enable for usability cases to be built on top of Ncat that aren’t possible or comfortable for the command line version of this tool.
