# Integration and tenant risk score

> Learn how Plerion calculates integration and tenant risk scores by aggregating asset risk scores into banded ranges.

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.

<Note>
  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

2. **Calculate the sum of risk scores**: Add together the risk scores of all assets.

3. **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).

4. *Adjust within the band*\*: Use the risk-to-worst-case ratio to place the score inside the selected band.

5. **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.
