About Us

Kontra is not your typical application security training company. We don’t believe in basic code quizzes, outdated exercises, or trainings that simply check the box.

Our mission is to provide the most advanced and cutting-edge interactive, web-based developer security simulations and education.

Powered by ThriveDX, our scalable technology revivents and reimages enterprise application security education for the modern developer—all while supporting our pursuit to close the skills shortage in cybersecurity.
