Zenmap

Zenmap is an open source network exploration, security auditing, and visualization tool. It is the official GUI of the Nmap Security Scanner, one of the most popular port scanning tools available. Zenmap allows for easy discovery of hosts and services on a computer network, as well as security auditing with the help of Nmap scripts. It is designed to be useful for both novice and experienced network administrators.

Features:

• Discovery: Zenmap provides quick and easy discovery of active hosts and services on a network. It shows open ports, service versions and the detected operating system of each host, and the Hosts and Services views let you browse the results either way.

Zenmap provides an easy-to-use graphical interface to the Nmap port scanning tool.

• Security Auditing: Zenmap can be used for security auditing and testing. It can be used to detect open ports and running services, and the Nmap Scripting Engine scripts it can run check hosts for known vulnerabilities and weak configurations.

• Visualization: Zenmap provides an intuitive user interface with graphical representations of a network. The Topology tab draws an interactive map of the discovered hosts and the network paths between them.

• Profiles: Frequently used scans can be saved as profiles, such as the built-in Intense scan, and run again with one click. The profile editor builds Nmap command lines interactively, so beginners do not need to memorise command line options.

• Saving and Comparing: Scan results can be saved to files and opened later. Two saved scans can be compared to see how they differ, and the results of recent scans are stored in a searchable database.

• Flexibility: Zenmap is designed to be customizable and extensible. It runs on Linux, Windows, macOS and BSD, and it accepts any Nmap command line options and scripts to customize and extend its functionality.

• Support: Zenmap is developed together with Nmap by a large and active community of users and developers. It is regularly updated with new features and bug fixes.

• Compatibility: On Windows, Zenmap is included in the Nmap self-installer together with the Npcap driver, Ncat and Ndiff. On other systems it is also available as a separate Python 3 package.

• Documentation: Zenmap has a user guide in the official Nmap documentation, and its Help menu opens the help pages and a form for reporting bugs.
