Overview
Network Scanners are cybersecurity tools designed to discover and inventory devices, services, and configurations across networks by sending probing packets. They enable rapid mapping of an attack surface, support asset management, vulnerability assessments, and incident response, but can be exploited by attackers for reconnaissance. Common examples include Nmap, Masscan, and Nessus, which vary in speed, stealth, and depth of fingerprinting, and can be used across local networks, VPNs, or cloud environments.
