Nmap, short for Network Mapper, is a free, open source tool used to check for vulnerabilities, scan ports, and, of course, network mapping. Although established in 1997, Nmap remains the gold standard against which all other similar instruments are valued, whether commercial or open source.

Nmap has maintained its superiority due to the large community of developers and coders who help maintain and update it. The Nmap community reports that the tool that everyone you can get it for freeis downloaded several thousand times each week.

Due to its flexible open source database, it can be modified to work in most customized or highly specialized environments. There are distributions of Nmap specific to Windows, Mac and Linux environments, but Nmap also supports less popular or older operating systems such as Solaris, AIX or AmigaOS. The source code is available in C, C ++, Perl and Python.

The last major update was Nmap 7.90 in October 2020, which included more than 70 bug fixes and improvements, as well as various system build upgrades and code quality improvements.

What is Zenmap?

To deploy Nmap, users initially had to have some advanced programming skills, or at least know how to bypass console commands or non-graphical interfaces. This has changed recently with the introduction of Zenmap tool for Nmap, which adds a graphical interface that makes starting the program and analyzing the returned result it generates much more accessible.

Zenmap was created to allow beginners to use the tool. Like Nmap, Zenmap is free and the source code is open and accessible to anyone who wants to use or modify it.
