Capture the flag.
Prove the skill.
Hands-on cybersecurity challenges across web, crypto, forensics and more, built to train the instincts a real engagement demands.
What CyberFlag is
CyberFlag is CyberNet.ae's Capture The Flag platform: a set of hands-on security challenges spanning web exploitation, cryptography, forensics, OSINT and more. Each challenge is a small, self-contained problem. Break something, find something hidden, or reverse something obscured, then submit the flag it produces.
It exists to build practical skill, not just theory. Every category mirrors the kind of problem you'd meet in a real engagement, scored and ranked so progress is measurable.
