Engage in Exciting Problems

The Oresec High School CTF Competition is a a competition for high school students to solve cybersecurity problems that they can then apply to secondary education or the work force!

Challenges are designed to be accessible to students with a wide range of experience, from beginners to experienced competitors. We encourage students to work in teams of up to 4, and we provide a supportive environment for students to learn and grow.
