No install. Runs entirely client-side — nothing but a ~40 MB download.
You don't see the attacker's plan; you infer it. Every kill and every alert feeds an evidence-driven timeline that estimates where the intruder is in their campaign — and how confident you should be.
Each mission maps a real-world campaign — with MITRE ATT&CK technique references — onto the board: hospital ransomware crews, kill-switch sabotage, the SolarWinds supply-chain compromise, the MOVEit mass-exploitation breach, and a growing library beyond that.
Virtual patching, quarantine, honeypots, threat intel, SIEM coverage, and residual persistence — evicting the intruder isn't the same as being safe.
The scenario library keeps growing. Leave your email and we'll let you know when a new incident goes live — nothing else, unsubscribe anytime.
