What is Capture The Flag (CTF)?

A Capture The Flag (CTF) competition is a hands on cybersecurity challenge where participants solve security puzzles, identify vulnerabilities, and uncover hidden “flags” to score points. Each flag is proof that a problem has been successfully solved, turning learning into a fast paced battle of logic, skill, and creativity.

Designed for both beginners and experienced professionals, our CTF features challenges across three high impact domains:
