Tabletop exercise library

100 ready-to-run cyber tabletop exercises across 15 incident domains. Search them, pick one at random, or tell us who will be in the room and we'll rank the scenarios that fit those people best. Every exercise shows who to involve, how long it runs and an outline — and the scenario prompt is free to copy and read out.

Running one for real? Pro adds the facilitator's run sheet for each exercise: a minute-by-minute timeline, timed injects, step-by-step facilitation guide and the questions to put to each person. Or build your own with the Tabletop Runbook Generator.

Who's in the room?

Pick the people you have — we'll suggest exercises that fit them.

Your signed software update is backdoored and customers have installed it

A customer's security team calls your CISO at 07:30. Their EDR flagged your desktop agent, version 9.4.1, released nine days ago and signed with your code-signing certificate, making outbound connections to a domain registered last month. Your engineers confirm the binary contains code that is not in your repository. Telemetry says 3,100 customer organisations have installed 9.4.1, including hospitals and two government agencies. The customer says they will post their findings publicly at noon. Your auto-update service is still offering 9.4.1 right now.
