David Adrian

I am somewhere between a security person, startup person, and academic. Most recently, I was a product manager at Google, working on adding value to Chrome Security. Previously, I cofounded Censys, an attack-surface management security startup. I left Censys after their Series A. They’ve since raised a Series B Series C Series D! I was employee #2 at Nametag. I’m also a core contributor to the ZMap open-source project. I have a PhD from the University of Michigan. I defended in 2018. My advisor was J. Alex Halderman. My research focus was using Internet-wide scanning to measure how cryptography is used on the Internet. It led to the discovery of the Logjam and DROWN attacks on TLS, and the creation of Censys.
