Hi, my name is Engue Gillier and I’m an Information Security Engineer at Facebook, previously Tenable.

As a Bug Hunter I reported hundreds of vulnerabilities to Google (3 years in 0x0A List), Facebook, WordPress, Uber, Paypal and many more. You can find me on Twitter, LinkedIn, HackerOne, BugCrowd and … in London. I’m specialized in Web Api security and Vulnerability automation and management.

I’m also passionate about cryptography and wrote a free course in french about Applied Cryptography. In this blog I publish technical write-ups for some of my findings, hoping to help the developer and infosec community make the web a safer place!
