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.
At 02:15 the HMI at a regional dairy shows the pasteuriser hold-tube temperature setpoint has moved from 72.5°C to 68.0°C. Nobody on the night shift admits to changing it. The change log names the engineering workstation's shared login, and that workstation sits in a locked, empty office. The flow-diversion valve worked and no under-temperature milk left the line, but 9,000 litres are now held in a silo pending a decision. The morning tanker leaves at 06:00. Was this an attacker, a scheduled job or a mistake, and how do you find out without destroying the evidence?
You are on day two of investigating suspicious traffic inside the control network of a chemical blending plant. Responders have a laptop on the OT switch capturing packets. At 14:20 the safety instrumented system trips reactor R-3 on high pressure, venting to the flare and closing the feed valves. The control room saw the pressure transmitter spike, but two field gauges read normal throughout. Operators want to reset the safety system and restart the batch, which is worth $400,000. The responders want the safety controller left untouched until they know whether anyone has reached it. Who decides?
Your SOC flags outbound connections from 40 networked infusion pumps on the oncology and intensive care floors to an IP address in a hosting range nobody recognises. The traffic started after last week's vendor maintenance visit. As far as nursing staff can tell, the pumps are still delivering medication normally. The manufacturer's support line says a patch is 'in validation' and will not commit to a date. Clinical engineering owns the pumps, IT owns the network, and the vendor holds the admin passwords. Pulling the pumps means moving patients to manual pumps you do not have enough of. What do you do in the next hour?
