NmapSI4 is a powerful network security and exploration tool used by system administrators and security professionals to find and identify open ports, services, and vulnerabilities on networks. It can be used to scan a single host, a range of IP addresses, or an entire network to discover which devices are available, what services they are running, and what potential security risks they may pose. It can also be used to detect open ports and services on a target system, as well as detect any potential weaknesses that can be exploited. NmapSI4 is free and open-source, and provides an intuitive user interface and user-friendly options to customize scans to meet the needs of its users.
