Shodan is the world’s first search engine for Internet-connected devices, continuously scanning the public web for routers, servers, webcams, IoT systems, and industrial control devices. 

It catalogs exposed ports, banners, and configurations to offer an unparalleled view of the global digital landscape. Security researchers, red teams, and infrastructure defenders rely on Shodan to identify misconfigurations, locate vulnerable systems, and assess organizational exposure. By addressing the core problem of hidden network risk, Shodan reveals what’s publicly accessible—often without organizations realizing it. With powerful filters, live feeds, and alerting, Shodan enables teams to detect exposure before attackers do.
