Ransomware Exposure Cost at 36% share of systems in the modeled scenario: a worked example

Suppose share of systems in the modeled scenario falls to 36%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate ransomware exposure cost for OT operations using affected recovery units, cost per unit, expected scope, and fixed response costs.

The inputs for this scenario

  • Affected OT systems needing recovery: 18 systems (held at the documented default)
  • Recovery cost per affected OT system: 22,000 $ / system (held at the documented default)
  • Share of systems in the modeled scenario: 36 % (the input this scenario stresses; the baseline uses 50)
  • Fixed ransomware response cost: 85,000 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable ransomware exposure cost = affected OT recovery units × cost per affected recovery unit × scenario scope included.
  • Total ransomware exposure cost works out to 227,560 $ at these inputs, and this is the headline figure for the scenario.
  • Cost per affected recovery unit works out to 12,642 $ / system at these inputs.
  • Variable ransomware exposure cost works out to 142,560 $ at these inputs.
  • Fixed ransomware response cost works out to 85,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where share of systems in the modeled scenario sits at 50% and the headline result is 283,000 $, this scenario comes in 19.59% below the baseline at 227,560 $.
  • It computes total ransomware recovery exposure by scaling per-system recovery cost across the scoped number of affected OT systems and adding fixed response cost. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Total ransomware exposure cost: 227,560 $ (headline result)
  • Cost per affected recovery unit: 12,642 $ / system
  • Variable ransomware exposure cost: 142,560 $
  • Fixed ransomware response cost: 85,000 $
