The platform

Everything you need to train like an attacker

One range, every discipline. From your first flag to full network compromise.

Wargames & Challenges

A curated arsenal of CTF-style challenges across web, pwn, reverse engineering, crypto and forensics — each with community difficulty ratings, solve stats and author writeups.

On-Demand Labs

Spin up isolated, dedicated attack environments in seconds. Full VMs and containers provisioned on real infrastructure — no local setup, no VPN gymnastics.

Network Challenges

Multi-host topologies with public-IP targets, routers and pivot chains. Map the network live, compromise hosts and capture root flags on a shared canvas.

Showdown — 1v1 Duels

Challenge anyone to a head-to-head race. First to submit wins. ELO ratings, sudden-death rounds and a ranked ladder decide who's really faster.

Courses & Pathways

Structured curricula that chain lectures, quizzes and hands-on challenges into guided pathways. Gated progression and certificates on completion.

Competitions & Events

Run or join live CTFs and timed competitions with real-time scoring, dynamic points and a public leaderboard that updates as flags land.

Teams & Leaderboards

Compete solo or rally a squad. Track ranks, streaks and category mastery on global and private leaderboards.

For Organizations

Isolated network labs, private leaderboards, org-restricted content, single sign-on and a full trainer portal to manage your people and curriculum.

How it works

From signup to root in four steps

01

Create your account

Sign up in seconds and land in the Arena. No installs, no configuration.

02

Launch an environment

Pick a challenge or lab and deploy a live, isolated instance on demand.

03

Hack & capture the flag

Exploit the target, submit the flag and climb the leaderboard.

04

Track your mastery

Follow progress across categories, earn certificates and level up.

Showdown

Head-to-head. Winner takes the rating.

Queue up or challenge a rival directly. You both get the same target — first to submit the flag wins the round. Sudden-death breaks the ties, and a K-factor ELO ladder keeps everyone honest. Climb from challenger to the top of the board.
