You love brainteasers, enjoy digital challenges and sometimes wonder how far your skills could really take you?
The CTF Challenge at CLOUDYRION is your chance to find out; with exciting tasks, like-minded people, and authentic hacker vibes.

At CLOUDYRION, we’re living proof that hackers don’t just exist in dark basement rooms. And yes, they do talk to people. Voluntarily. Here you’ll meet real cybersecurity experts who value not only leakproof systems, but also teamwork, laughter, and great conversations. We’re a team redefining security while still appreciating the importance of community, fun, and, of course, good snacks.

We invite cybersecurity enthusiasts to step up to the challenge. This round comes with something special: an exclusive CLOUDYRION-Challenge tailored for participants with prior CTF experience. It’s the perfect opportunity to push your skills further, exchange ideas with professional ethical hackers, and get a real taste of community-driven cybersecurity.

All you need is a Wi-Fi enabled laptop with any operating system or virtual machine (Linux preferred).
