Build a tabletop exercise before you need one for real.

Generates a HSEEP-aligned Master Scenario Events List (MSEL) for a data-incident exercise — pick a category, a target recovery window, an audience, and a duration, and get a full inject timeline you can run as-is or hand straight to Tabletop.

Configure the exercise

Every field below shapes the generated MSEL — there's no single "correct" combination, just the one that matches what you're actually trying to test.

Incident category

Target RTO/RPO window Frames the urgency in the briefing and the ticking-clock line — not a live countdown.

Target audience / maturity level

Inject frequency / exercise duration Sets how many injects are generated and how they're spaced across the session.

Configure the exercise above and generate an MSEL to see it here.
