Censis is a search engine that collects data about the configuration of web pages and the host of the IPv4 address space and combines it in a database. It was developed by a team of researchers at the University of Michigan and Illinois Urbana-Champaign. It starts 2016 as Censis. The original goal was to measure whether Internet security is actually improving. Today, Censis is a tool for security researchers, governments and businesses that enables them to evaluate Censis data for potential risks.

|Censys - About: »The foundational technology behind Censys was designed by researchers at the University of Michigan. This team also created the ZMap Scanner, which helped popularize Internet-wide scanning.
Their original goal was to provide researchers with a way to measure if Internet security was actually improving. To accomplish this, they needed to track security vulnerabilities on every reachable server and device on the Internet, and collect as much data as possible about those hosts. The result was a searchable map of the Internet, which became a powerful tool for security researchers.
This map also proved valuable to the broader information security community. Corporate security teams and consultants were also using it to identify business infrastructure and to prevent unnecessary exposure on the Internet.
In 2017, the founding research team partnered with two seasoned product leaders to build a company with the mission of helping organizations secure themselves through visibility and real-time data.« Source|
|About (2018): »Censys started as an academic research project at the University of Michigan and Illinois Urbana-Champaign in 2015 by a team of computer scientists including: David Adrian, Michael Bailey, Zakir Durumeric, J. Alex Halderman, and Ariana Mirian.
In 2017, Censys spun-out from the University of Michigan into an independent organization founded by several of the original Censys members (Zakir, David, and Alex) along with Brian Kelly and David Corcoran. Censys is currently maintained by: David Adrian, Justin Bastress, David Corcoran, Zakir Durumeric, Chris Dzombak, Alex Halderman, and Brian Kelly.«
Features & Functionality
|»Censys is a search engine that enables researchers to ask questions about the hosts and networks that compose the Internet. Censys collects data on hosts and websites through daily ZMap and ZGrab scans of the IPv4 address space, in turn maintaining a database of how hosts and websites are configured. Researchers can interact with this data through a search interface, report builder, and SQL engine. « Source|
