Shodan
Search Engine for the Internet of Everything
Shodan is a search engine designed to discover and index devices connected to the internet, such as servers, webcams, industrial control systems, and home routers. It solves the problem of gaining visibility into the vast number of internet-connected devices beyond traditional websites, helping organizations monitor their network exposure and understand the technology landscape across the internet.
The platform includes several products: Shodan Search for querying device data, Shodan Monitor for tracking exposed services and receiving real-time notifications, Shodan Maps for geographic exploration, and Shodan Images for browsing service screenshots. Developer tools include a public API for programmatic access, the InternetDB API for quick port lookups, the GeoNet API for running network tools from global servers, and the CVEDB API for vulnerability insights. Browser extensions for Chrome and Firefox provide quick security views of websites.
Shodan is used by security professionals, network administrators, and researchers. It offers a free tier with limited access, while more comprehensive features and higher usage limits are available through paid subscriptions. The enterprise edition provides full, unlimited access including bulk data.
