About Shodan
Shodan is a search engine for devices connected to the internet, such as servers, cameras and industrial equipment. It crawls the internet regularly and lets you search the results.
What it does
Shodan records which services respond on which IP addresses, so you can see what is exposed on a network. Its Monitor feature lets you watch your own ranges and receive alerts when something new appears. The developer API gives tools and scripts access to the same data for lookups and streaming.
Key features
- Search for internet-connected devices and banners
- Monitor your own exposed services with alerts
- Developer API for lookups and data streaming
- Chrome and Firefox extensions for quick site checks
- Exposed services view across IP ranges
Who it's for
Shodan suits security researchers, network administrators and developers who need to map exposed services. The same data can be misused, so use it only on systems you are allowed to examine.
Pricing and good to know
A free account is available with limited features. Paid memberships, API subscriptions and enterprise plans are listed on the site. The browser extensions cover Chrome and Firefox, and the help center has guides for common tasks.
