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.

It is 09:00 on Black Friday at an online homeware retailer that takes 18% of its annual revenue in the next four days. Requests to the checkout API jump to 40 times normal, response times pass ten seconds and the site starts returning errors. An email arrives at the press address: pay 5 bitcoin or the site stays down all weekend. Your CDN has basic DDoS protection, but the checkout API sits outside it on a separate hostname. Marketing has a promotional email going to 3 million customers at 10:00. What do you do in the next hour?
At 09:31 on the morning of a major interest-rate announcement, your online brokerage's order-entry service starts returning errors. Customers can log in and see positions but cannot place or cancel orders. Traffic is four times a normal day. A configuration change to the order-routing gateway went out at 08:50, and the network team is also seeing a surge from a few thousand IP addresses that could be a DDoS or could be your own customers' apps retrying. Customers with open positions are posting angrily on social media. Roll back, scale out or block traffic? You have one move to make first.
It is 20:05 on Black Friday. Your online retailer's checkout has been failing for 18 minutes; about one payment attempt in three times out. The promotional email to 2.4 million customers went out at 20:00. Revenue for this hour last year was $1.9 million. Engineering thinks the payment provider is rate-limiting you; the payment provider says its systems are healthy. Social media has noticed, and a competitor has just extended its own sale by an hour. The CEO has joined the bridge and wants to know whether to pause the promotion. What do you decide in the next ten minutes?
