How it works

  1. Scope — what you're analysing and your loss tolerance.
  2. Current exposure — the loss scenarios you're exposed to today, each as a frequency and magnitude range.
  3. Interventions — the security actions you're weighing, with cost ranges.
  4. Effects — how each intervention shifts each scenario's frequency or magnitude.
  5. Results — loss exceedance curves, a return-on-investment distribution, and a tornado diagram ranking interventions by impact.

No account needed — your analysis is saved to a private link as you go. Nothing is shared until you say so.
