1000+

Definitions, up from 300+ in the previous scoring model

0–100

Score scale

Your initial score may increase or decrease.

The scoring method and definition coverage have changed. This reflects a new methodology, not a decline in platform health.

Overview

What's happening

|

Why your score matters

The previous scoring model weighted findings equally, so critical risks could be less visible. The new risk-weighted scoring model tells you how healthy your platform is overall. Drill into the findings to determine where to focus.

Our approach

Why we're doing this

|

Aligned with best practice

Risk-weighted scoring is industry standard across large cloud and SaaS platforms.

Credibility

A score tied to risk helps you connect your work to business outcomes such as faster deployments, lower platform risk, and better adoption.

Clarity

Remediation priorities become clearer. Start with the high-risk items and see your score reflect that progress. Lower-impact issues can wait.

Completeness

You see a fuller picture of your platform health, based on expanded definition coverage.

|

|

What to expect

Your score may change initially

|

What to expect

Your initial score under the new risk-weighted scoring model may increase or decrease because the scoring method and definition coverage have changed. This does not necessarily indicate a sudden change in your instance. It establishes a new baseline based on the expanded, risk-weighted model.

Score changes reflect a new scoring methodology rather than a decline in platform health.
|

|

•   Prioritize fixes by impact, because high-risk fixes tend to move your score the most

•   Report progress to leadership with a more risk-aware view of platform health
|

How it works

How the score is calculated

|

Weigh each definition

W = DW × S × (Impact ÷ 10) × A
|
|
2
|
Measure how widely it fired

M = 1.0 + log10(1+R) ÷ log10(1+Rmax)
|
|
3
|
Add up the risk that fired

B_fired = sum of (W × M) for fired definitions
|
|
4
|
Set the ceiling

B_max = sum of (W × 2.0) for all definitions
|
|
5
|
Score it

100 × (1 − B_fired ÷ B_max), rounded down
|

|

|

Example data

What each fix is worth

|

Example data

Platform Health Score after each remediation path (0–100)

| Baseline |

 

| 21 |
| Fix 190 UX findings |

 

| 23 |
| Fix 4 Security findings |

 

| 41 |
| Fix 6 Security findings |

 

| 62 |
| Fix Security + slow query |

 

| 73 |

Illustrative example: a 10-definition library that starts at a score of 21. Six Security fixes add 41 points. 190 UX fixes add 2. Your results will differ.

Frequently Asked Questions

|

Who gets the Platform Health Score?

Customers using the Platform Health experience in Impact Store App v12. Health Assessment reports continue to use the existing Health Assessment scoring model.

How does the Platform Health Score differ from a Health Assessment score?

The Platform Health Score in the Impact app provides an ongoing view that can be refreshed through subsequent scans as findings are addressed. A Health Assessment score represents the results captured for a specific assessment report and continues to use the Health Assessment scoring model. Because the experiences use different scoring models, their scores should not be compared directly.

Did my platform get less healthy?

The underlying health of your platform did not change because of the scoring update. The score under the new risk-weighted scoring model evaluates platform risk using broader definition coverage and risk weighting, which may produce a different result.

How much will my score change?

It depends on your configuration and findings, and your score may increase or decrease. Run a Full Scan to establish your baseline under the new risk-weighted scoring model.

When does the new scoring take effect, and will it change my past scores?

The new risk-weighted scoring model applies when you run a new Full or Delta Scan in your Impact Store App. It doesn’t recalculate scores from earlier scans, so your historical scores stay as they were. Run a Full Scan to establish your baseline under the new model.

How is the score under the new risk-weighted scoring model calculated?

Each definition has a weight based on severity, category, and impact. Your score reflects the ratio of weighted definitions fired to the weighted definitions that could have fired. A detailed guide with the full formula is attached at the bottom of this article.

What does the score tell me to do first?

Start with the highest-risk findings, beginning with Act-level Security findings, and work your way down. You'll see your score move noticeably when you fix high-impact items.

Does this affect my other metrics (compliance, uptime, etc.)?

This update applies to the Platform Health Score. Your other metrics and reports are not part of this change.

|

|

The bottom line

Your score now provides a more risk-aware view of platform health. It shows where risk sits and which fixes matter most, so you can turn findings into a clear action plan.
