About Insider Threat Risk Score Calculator

Insider risk is driven by the product of access and data sensitivity — the potential impact — uplifted by behavioural indicators such as unusual access patterns, resignation notice or policy violations. Monitoring does not remove the access, so it can only mitigate part of the inherent risk; the residual score is what should drive access reviews and just-in-time privilege decisions.

Formula

Insider risk score

inherent = access level x sensitivity level x 4 + 5 x behavioural flags; residual = inherent x (1 - 0.6 x monitoring coverage)

Worked example

With the default values below, Insider Threat Risk Score Calculator returns Residual insider risk score (0-100) of 57.6. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Why can monitoring not reduce risk to zero?

Detection happens after the action. It shortens the window and supports investigation but does not prevent a privileged user from exfiltrating data they are authorised to read.

What reduces inherent insider risk?

Removing standing privilege. Just-in-time access, approval workflows and separation of duties lower the access term rather than merely observing it.
