“We struggled with our own infrastructure for a few years before switching to CTFd.

We anticipated that the slick interface, easy configuration, and stability would be a big win for us, but what surprised us was what we weren’t expecting: our data got better.

We finally got accurate stats and were able to seamlessly collect the data we need for global recruitment. CTFd has made it easier for us to scout blue-chip prospects and elite veteran tech talent for our company.”

Nick Harbour, FireEye
