What is Shodan?
Shodan is a search engine for Internet-connected devices. Web search engines, such as Google and Bing, are great for finding websites. But what if you’re interested in measuring which countries are becoming more connected? Or if you want to know which version of Microsoft IIS is the most popular? Or you want to find the control servers for malware? Maybe a new vulnerability came out and you want to see how many hosts it could affect? Traditional web search engines don’t let you answer those questions.
How is it different than Google?
The most fundamental difference is that Shodan crawls the Internet whereas Google crawls the World Wide Web. However, the devices powering the World Wide Web only make up a tiny fraction of what’s actually connected to the Internet. Shodan’s goal is to provide a complete picture of the Internet.
Another difference with Google is that Shodan requires you to understand the search query syntax. For example, you can’t simply enter power plant into Shodan and expect to get proper results. We designed Shodan for engineers/ developers and to get the most out of the data you need to understand the search query syntax.
