Hands-on live labs
Browser-based terminals and remote desktops running against real cloud environments. Challenges provision isolated sessions on demand and tear them down cleanly when you're done.
A capture-the-flag platform for individual players and security teams. Run live events, solve hands-on challenges in live cloud environments, and compete on global or private leaderboards.
Challenges span multiple cloud and container platforms — we keep adding more.
Everything you need to play, host, and measure capture-the-flag competitions — on live infrastructure, with the admin tooling real programmes require.
Browser-based terminals and remote desktops running against real cloud environments. Challenges provision isolated sessions on demand and tear them down cleanly when you're done.
Schedule public or private events with registration windows, start/end times, category filters, and per-challenge scoring rules. Run a one-off competition or a recurring programme.
Individuals compete on global leaderboards and track personal progress. Teams form around a captain plus co-captains, pool their scores, and coordinate on shared challenges.
Static and regex flag types, first-blood tracking, duplicate-submission detection, IP and session logging, and rate limiting. Anti-cheat fundamentals built in from day one.
Granular moderator permissions across dozens of capabilities, full audit trail, in-app broadcast notifications, and an event-level admin console — the controls a real programme needs.
Public player profiles, per-category skill progression, solve history, XP, and achievements. Measurable for individual players and aggregate views for team captains.
Whether you're sharpening your own skills, running a team, or organising a competition, CloudBattles CTF adapts to the shape of your use case.
Free accounts with a public profile, solve history, XP, and achievements. Join public CTF events when they open, or work through the challenge library at your own pace.
Team-based scoring with a captain-plus-co-captain structure, shared leaderboards, and per-role dashboards. Designed for organising competitions, not just playing.
Schedule private or public events, manage registrations, broadcast updates mid-event, review the audit trail, and moderate submissions with role-based admin tools.
From account creation to live competition in three steps.
Sign up free as an individual, or invite your team. Personal profiles include solve history and progress across categories.
Join a public CTF event, practise against the challenge library, or — for organisations — host your own private competition with full admin controls.
Challenges run in isolated cloud environments. Submit flags, earn points, watch the leaderboard update, and see your skill progression grow over time.
Built by CloudBreach
CloudBattles CTF is built by CloudBreach Ltd, the cloud-security company behind courses used by red teams, blue teams, and security engineers worldwide since 2021.
The same lab orchestration that powers those courses drives CloudBattles CTF: real cloud environments, provisioned on-demand, isolated per session, torn down cleanly. No simulators, no shortcuts.
