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.
You run a municipal water utility serving 38,000 people. At 11:05 an operator watches the cursor move across the SCADA screen on its own and raise the sodium hydroxide dosing setpoint from 90 to 5,400 parts per million. He resets it within a minute, and downstream pH alarms would have caught it before treated water reached a tap. The workstation runs remote-access software installed years ago so the on-call operator could work from home. The mayor’s office has already heard about it from a council member. Do you tell the public, and what do you say?
You run IT for a mid-sized water utility in the EU, classed as an essential entity under NIS2. At 06:30 monitoring shows that the remote-access gateway used by contractors has been accepting logins from an unfamiliar country for two nights, and the telemetry server it reaches is behaving oddly. Nothing has failed, and operations say pumping is normal. The national CSIRT expects an early warning within 24 hours of becoming aware of a significant incident. Is this significant, when did the clock start, and who sends it?
