If you are responsible for teaching a large number of students, I want to help. Whether it is a classroom, a CTF team, your business, whatever, I am looking for groups of 10+ to learn how to help other educators teach their classes.

Email me at to discuss how Roppers can train your students.

I work for the US Navy as a Cyber Warfare Engineer. Back in school I was on our competitive Cyber Security Team and focused on building training for new members. I made this website to continue the work I had done and to share it with the widest audience possible.
