Johan Sydseter firmly believes that application security should be played, not preached. Rather than relying on slide decks and talking heads, he champions games as a way to create agency, empathy, community, and long-term learning, helping teams remember why security matters long after the session ends.

We were delighted to work with Johan as a judge for the CyberSec Game Challenge 2025, where his reviews were thorough, insightful, and rich with constructive feedback. We’re very much looking forward to working with him again on the next version of OWASP Cornucopia.
