Nmap vs scanless
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 scanless
scanless is a Python command-line utility that performs port scans anonymously by routing scan requests through third-party online port scanning services rather than sending packets directly from the operator's IP address. It aggregates results from multiple web-based scanners to provide port status information while keeping the operator's true network address hidden from the target. Penetration testers and red team operators use scanless during the initial reconnaissance phase when they need to identify open ports without triggering the target's intrusion detection systems or revealing their infrastructure. The tool is particularly useful for stealthy external reconnaissance and for validating firewall rules from an outside perspective without directly touching the target network.
