Our competitions
2084 CTF at HackYeah 2025 and Reentry CTF at HackYeah 2026 — probably Poland's largest on-site CTF competitions. Challenges, platform, infrastructure and live operation were all on us: from the first flag to the final scoreboard.
CTF as training
A private competition for your team is the fastest way for developers and admins to see vulnerabilities from the attacker's side — in a safe, gamified environment. We match the challenges to your stack and the participants' level, and hand over solutions and learning material afterwards.
How we run it
- Challenge design — jeopardy or attack/defence, from web and cryptography to forensics and reverse engineering.
- Platform and infrastructure — per-team instances, monitoring and technical support during the event.
- Operation — briefing, participant support, a live scoreboard and a summary.
- Experience from both sides — we play in top CTF teams ourselves and win awards in competitions such as DEFCON Crack Me If You Can.
