OT Risk Mitigation Payback with ot mitigation investment of 437,500 $: a worked example

Push ot mitigation investment up to 437,500 $ and the picture changes. This example computes every intermediate figure at that operating point. Use it to compare mitigation options such as monitoring, segmentation, backup recovery, asset inventory, or access control improvements.

The inputs for this scenario

  • OT mitigation investment: 437,500 $ (raised for this scenario; the documented default is 175,000)
  • Annual OT risk reduction savings: 72,000 $ / yr (unchanged)
  • Annual mitigation support cost: 18,500 $ / yr (unchanged)

Working through the calculation

  • Applying the documented formula (Net annual OT mitigation savings = annual OT risk reduction savings - annual mitigation support cost) to the inputs above produces each figure below.
  • At this operating point the engine returns 8.18 yr for ot risk mitigation payback period, the number this scenario is built around.
  • At this operating point the engine returns 53,500 $ / yr for net annual ot mitigation savings.
  • At this operating point the engine returns 437,500 $ for ot mitigation investment.
  • At this operating point the engine returns -170,000 $ for five-year net ot mitigation value.

How this compares with the baseline

  • Against the tool's baseline example, where ot mitigation investment sits at 175,000 $ and the headline result is 3.27 yr, this scenario comes in 150% above the baseline at 8.18 yr.
  • It divides the OT mitigation investment by net annual savings — annualized risk-reduction benefit minus ongoing mitigation support cost — to return payback in years. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
