Censys is a startup that monitors all enterprise devices connected to the internet and creates security products to help corporations identify vulnerabilities. Prior investors include Google Ventures and Greylock Partners. Founded in 2015, Cenys started as a research project at the University of Michigan called ZMap. It was spun out in 2017 in order to convert ZMap’s open source traction into a commercial product. The company’s attack-surface scanning application creates the broadest, deepest, and relevant data set and yields greater visibility into vulnerabilities for their enterprise customers.
