The digital legend awaits. Explore it, understand it, conquer it.

What CyberLANTIS Means
CyberLANTIS is the theme of CyberSea Festival 2026: a digital world that must be explored, understood, and built responsibly — a sunken city of systems waiting beneath the surface.
The CTF challenges are designed, built, and operated by Chronos Security around realistic scenarios: the technologies, protocols, and mistakes you meet in real environments.
