Nmap vs Tsunami
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 Tsunami
Tsunami is a network security scanner developed by Google designed for detecting high-severity vulnerabilities with high confidence at scale. It operates in two phases: first scanning for open ports and services using nmap/ncrack integration, then running vulnerability detection plugins against discovered services. Tsunami focuses on minimizing false positives and only reports vulnerabilities it can verify. Its plugin system allows community contributions for new vulnerability checks. Designed for enterprise-scale networks where manual verification of every finding is impractical.
