About
Nmap (Network Mapper) is a free, open-source tool for network discovery and security auditing. It uses raw IP packets to identify hosts, open ports, running services, operating systems, and firewall configurations across networks of any size. The suite includes a GUI frontend (Zenmap), a data transfer tool (Ncat), a scan comparison tool (Ndiff), and a packet generation tool (Nping).
Problem
Network administrators and security professionals need a reliable way to discover hosts, open ports, and vulnerabilities across their networks.
For
System administrators, network engineers, and security auditors
How it works
Nmap sends raw IP packets and analyzes responses to map network topology, detect services and OS versions, and identify firewall configurations via command-line or GUI.
