EDR Agent Coverage at 65% target edr coverage threshold: a worked example

Suppose target edr coverage threshold falls to 65%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate endpoint detection and response coverage across eligible OT and manufacturing support endpoints.

The inputs for this scenario

  • Eligible OT endpoints with approved EDR agent installed: 210 endpoints (held at the documented default)
  • Total eligible OT endpoints in scope: 260 endpoints (held at the documented default)
  • Target EDR coverage threshold: 65 % (the input this scenario stresses; the baseline uses 90)

Working through the calculation

  • The calculation starts from the formula this tool documents: EDR agent coverage = eligible OT endpoints with approved EDR ÷ total eligible OT endpoints × 100.
  • EDR agent coverage works out to 80.77 % at these inputs, and this is the headline figure for the scenario.
  • EDR coverage gap to target works out to -15.77 points at these inputs.
  • Eligible OT endpoints with approved EDR works out to 210 count at these inputs.
  • Total eligible OT endpoints works out to 260 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target edr coverage threshold sits at 90% and the headline result is 80.77 %, this scenario lands almost exactly on the baseline at 80.77 %.
  • It computes the percentage of in-scope OT endpoints carrying an approved EDR agent and the number of percentage points you sit above or below your coverage target. 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

  • EDR agent coverage: 80.77 % (headline result)
  • EDR coverage gap to target: -15.77 points
  • Eligible OT endpoints with approved EDR: 210 count
  • Total eligible OT endpoints: 260 count
