A hands-on cyber range. You break into simulated systems to understand exactly how attacks work — then every mission shows you how a defender shuts them down. Ten missions, four tiers, from your first command to reconstructing a full breach.
This is a sandbox. Every machine, account, log and network here is fictional and lives only inside this page. Nothing connects to the internet or touches a real computer. The skills are real; the targets are not — that's the only legal and safe way to learn this.
Mission Map
Clear a tier to unlock the next. Every mission teaches one real idea — and how to defend against it.
