VThe arsenal
Everything you need to run a CTF.
What ships with the platform today — no roadmap promises.
Write your own challenges
Multi-step challenges with flags, hints and scoring per question — no Docker files, no code.
Real lab machines
Challenges get live lab machines that start when players do and disappear when they finish: shared on Team, one per team on Pro, one per player on Enterprise.
Live tournaments
Multi-round events with a real-time scoreboard and a big-screen view for the room.
Your brand, your space
Your logo and colors — players see your brand, and your data stays separate.
SAML SSO and roles
Single sign-on with Okta, Azure AD, OneLogin and others on Pro and Enterprise — and roles for every action.
Public scoreboard links
Share a protected scoreboard link with stakeholders, sponsors or the audience — no login needed.
Progress you can see
Who is playing right now, who solved what, and where people get stuck.
