Data Loss Exposure at 29% share of events not protected today: a worked example

This worked example runs the data loss exposure numbers for a tougher week than the baseline: 29% share of events not protected today instead of the typical 40%. Estimate annual data loss exposure on the OT data path from outage events per year, dollar impact per event (lost analytics, regulator fine, missing batch record), the share of events not protected by store-and-forward or DR, and a fixed protection cost (replication, backup, redundant gateway).

The inputs for this scenario

  • OT data outage events per year: 6 events / yr (held at the documented default)
  • Dollar impact per outage event: 18,000 $ / event (held at the documented default)
  • Share of events not protected today: 29 % (the input this scenario stresses; the baseline uses 40)
  • Annual fixed protection cost: 22,000 $ / yr (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable data loss exposure = outage events per year × impact per event × share unprotected.
  • Total data loss exposure works out to 53,320 $ at these inputs, and this is the headline figure for the scenario.
  • Exposure per outage event works out to 8,887 $ / piece at these inputs.
  • Variable data loss exposure works out to 31,320 $ at these inputs.
  • Fixed protection cost works out to 22,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where share of events not protected today sits at 40% and the headline result is 65,200 $, this scenario comes in 18.22% below the baseline at 53,320 $.
  • Use it when building the business case for OT data protection (store-and-forward, redundant historians, edge buffering) or comparing the as-is exposure to a protected scenario. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Total data loss exposure: 53,320 $ (headline result)
  • Exposure per outage event: 8,887 $ / piece
  • Variable data loss exposure: 31,320 $
  • Fixed protection cost: 22,000 $
