Nmap (Network Mapper) is a powerful open-source tool used for network discovery and security auditing. It allows users to scan networks to identify live hosts, open ports, and available services, providing valuable insights into network infrastructure. Nmap also facilitates security auditing by detecting vulnerabilities and misconfigurations, helping assess the security posture of devices.
Additionally, it can determine the operating system and version running on remote hosts, enabling comprehensive network analysis. With its ability to create a detailed inventory of networked devices, Nmap aids in network management and troubleshooting.
Supporting Platforms: Windows, Linux and MAC
