A group of entities motivated by a common goal: to create and provide the best cyber security Capture-the-Flag events

The CTF Collective is comprised of companies and individuals that work together motivated by a common goal: to create and provide the best cyber security Capture-the-Flag events.

How we came to be

Most of us have been competitive in computer security CTFs for years (nay, decades), winning at the highest levels.

Additionally, many of us have also organized CTFs for years, including DEF CON CTF.

For these reasons, and others, The CTF Collective members joined forces to design, build and execute DARPA’s Cyber Grand Challenge in 2016.

You can see some of our work at Cyber Grand Challenge github and repo.

Affiliates not in ‘stealth mode’

Many other members are currently stealth mode. However, you can spot many of us in various Cyber Grand Challenge videos: Visualization, (more visualization), the framework team, or the entire program.
