The integration risk score and tenant risk score are calculated using a banded algorithm that aggregates the risk scores of individual assets. This algorithm is designed for fair comparison between tenants or integrations with a similar number of assets, since the total number of assets can otherwise skew results.
This is not an average of asset risk scores.

Algorithm steps

  1. Determine the band range: Identify the appropriate band by examining the highest leading integer among the asset risk scores:
  • Low: 0–4
  • Medium: 4–6
  • High: 6–8
  • Critical: 8–10
  1. Calculate the sum of risk scores: Add together the risk scores of all assets.
  2. Compute the risk-score-to-worst-case ratio: Divide the total risk score by the worst-case score (where every asset has a risk score of 10).
  3. Adjust within the band*: Use the risk-to-worst-case ratio to place the score inside the selected band.
  4. Set decimal precision: Round the final risk score to three decimal places for consistency.
Example: Consider an integration with three assets that have risk scores of 10, 9, and 8.
  1. Band range: Highest score is 10, so the band is Critical (8–10)
  2. Sum of scores: 10 + 9 + 8 = 27
  3. Risk-to-worst-case ratio: 27 ÷ 30 = 0.9
  4. Band adjustment: 8 + (0.9 × 2) = 9.8
  5. Final score: 9.8
In this case, the integration has a final risk score of 9.8, indicating a high level of risk.
