About Chronos Security
Romanian nonprofit for cybersecurity education
We organize competitions and educational programs that turn cybersecurity curiosity into practical skills. Free, open, community-driven.
From One Student to International
2023: One student. One idea. A county-level CTF competition in Sibiu, Romania — the Sibiu Military Cyber Challenge. Organized entirely by a single person with zero budget, partnering with military institutions and local universities.
2024: That same student scaled to national level with CSCTF 2024 — Romania's first fully online, open-format CTF. 250+ participants. National media coverage. Still largely a one-person operation.
2025: International reach. CSCTF 2025 brought 550+ participants from 30+ countries, EUR 8,000+ in prizes, 7 educational partners, and 5 sponsors. The association was officially registered.
Today: Chronos Security is a registered Romanian nonprofit. Everything earned goes back into competitions, education, and community. No shareholders. No profit extraction. Just building the next generation of cybersecurity talent.
