Register for open events on the CTF7 events page with a free player account. Our practice event, Ouroboros CTF, is launching soon. New to this? Follow the beginner practice roadmap. Ready for a security role? Browse jobs from teams hiring on CTF7.
Most events start with jeopardy. Raw Ops swaps flags for vulnerability reports scored with CVSS 4.0, and hackathons and hiring rounds reuse the same registration and teams. Attack-defense, King of the Hill and SOC simulation need live game infrastructure, so our team scopes and runs them with you.
Web, crypto, pwn, reverse engineering, forensics and OSINT boards with static or dynamic scoring, hints, first-blood bonuses and challenges that unlock on a schedule.
No flags. Players attack a target web app, file vulnerability reports, and your triagers score each valid report with CVSS 4.0. Chaining small bugs into real impact earns a bonus.
Every team gets the same vulnerable services. Patch your own, exploit everyone else's and keep services up through every tick.

player~/double-wrapped❯Solves, Raw Ops reports and leaderboard movement show up as they happen. From the organizer console you pause a broken challenge, post an announcement to every team and check players in at the venue.
Challenges unlock at the times you set, and the scoreboard can freeze before the finish so the last hour stays tense.

CTF7 for conferencesA CTF platform runs Capture The Flag competitions: players solve security challenges, each solve reveals a secret string called a flag, such as CTF7{example_flag}, and submitting it scores points on a live scoreboard. CTF7 also handles the event around the board: registration, teams, fees and fair play.
