Shodan Search

Shodan Search is the world's premier search engine for internet-connected devices, offering cybersecurity analysts, penetration testers, and threat intelligence researchers unparalleled visibility into the global landscape of internet-facing digital assets. Unlike conventional web search engines that index website text and metadata, Shodan actively scans the entire public IPv4 and IPv6 address space to collect, parse, and index the raw service banners returned by network devices and internet protocols. Through Shodan Search, users can discover and inspect millions of connected endpoints, including enterprise routers, industrial control systems (ICS/SCADA), webcams, database servers, IoT appliances, and cloud infrastructure components. The platform features an expressive search filter syntax, enabling practitioners to isolate targets by port, operating system, SSL certificate attributes, HTTP headers, geographic location, autonomous system number (ASN), and specific vulnerability CVE identifiers. Security teams utilize Shodan Search for proactive attack surface discovery, competitive benchmarking, threat intelligence gathering, and tracking the global proliferation of emerging software exploits. By illuminating exposed network infrastructure worldwide, Shodan Search remains an essential tool for defensive asset reconnaissance and proactive cybersecurity research.
