We Sponsor Hard CTFs

CTFs end. Great challenges should live on. We sponsor hard CTF events so their challenges can remain open and available to everyone.

Sponsorship Requirements

To be considered, your event must:

1. Be Difficult: Build a hard, technically challenging CTF.
2. Be Open Source: Release the CTF’s challenges under an OSI-compatible license.
3. Have a Proven Track Record: Show a history of successfully running the CTF, ideally across multiple years. We generally do not sponsor first-time events.

We review applications and select CTFs for sponsorship on an ongoing basis.
