GitHub Stats
About Nmap
Nmap (Network Mapper) is a free and open-source utility for network discovery and security auditing. It uses raw IP packets to determine available hosts, services, operating systems, packet filters/firewalls, and dozens of other characteristics. It was designed to rapidly scan large networks but works fine against single hosts. Nmap's scripting engine (NSE) allows users to write and share scripts to automate networking tasks, from vulnerability detection to backdoor discovery. It's used by security professionals, system administrators, and researchers worldwide.
About ZMap
ZMap is a high-speed network scanner designed to perform internet-wide scans using single packets. Capable of scanning the entire IPv4 address space in under five minutes, it is ideal for large-scale network research. Written in C, ZMap is used by researchers and security professionals to uncover open ports and services across vast network segments. Its efficiency and scale make it a vital tool for comprehensive network analysis.
