We engineer premium offensive-security challenges for CTF competitions worldwide.
From zero-days to AI exploitation — every challenge is a precision-crafted simulation.
Every challenge is architected from real-world vulnerability research. No generic CTF templates — only original, thoroughly tested simulation scenarios.
End-to-end CTF event packages including infrastructure, scoring systems, challenge distribution, and live support for your competition.
Challenges tuned to your target audience — from introductory jeopardy to elite university competitions and corporate security assessments.
Optional storyline and lore systems that transform isolated challenges into immersive multi-stage attack simulations with coherent narratives.
Ten offensive-security disciplines. Each engineered with domain-specific depth.
Live samples from our challenge library. Click any challenge to inspect and attempt the flag.

ARQADEX CTF Division is a specialized team of offensive security researchers, reverse engineers, and challenge architects.
We operate at the intersection of cybersecurity research and simulation engineering. Our challenges are built from real vulnerability classes, real exploit techniques, and real operational scenarios — not textbook theory.
Every team member has active CTF competition experience. We've competed at, placed in, and been invited to build challenges for events across Asia, Europe, and North America.
