Integration and Tenant Risk Score

The Integration Risk Score or Tenant Risk Score are calculated using a banded algorithm that aggregates the risk scores of individual assets. This algorithm is designed to compare tenants or integrations with an equal number of assets, as having more or fewer assets can influence the overall risk score. The algorithm is not an average of your asset risk scores.

The algorithm works as follows:

1. Determine the Band Range: The algorithm first identifies the appropriate band range for the risk scores by examining the highest leading integer among the asset risk scores. The possible band ranges are:
   1. Low Band: 0 - 4
   2. Medium Band: 4 - 6
   3. High Band: 6 - 8
   4. Critical Band: 8 - 10
2. Calculate the Sum of Risk Scores: The sum of all the asset risk scores is calculated.
3. Compute the Risk Score to Worst-Case Ratio: The algorithm computes the ratio of the sum of risk scores to the worst-case scenario (where all assets have a risk score of 10).
4. Adjust the Risk Score by Band: The final risk score is adjusted within the identified band range by applying the ratio of risk scores to the worst-case scenario.
5. Set Decimal Precision: The final risk score is rounded to three decimal places to maintain consistency.

Example: Consider a scenario where an integration has three assets with the following risk scores: 10, 9, and 8.

The algorithm will:

1. Identify the highest leading integer (10) and start the calculation in the Critical Band (8 - 10).
2. Calculate the sum of risk scores: 10 + 9 + 8 = 27.
3. Compute the risk score to worst-case ratio: 27 / 30 = 0.9.
4. Adjust the risk score within the Critical Band: 8 + 0.9 × 2 = 9.8.

In this example, the integration would have a final risk score of approximately 9.8, indicating a high level of risk.
