How Security Scores and Grades Work
Who this is for: Anyone interpreting vendor ratings — procurement, GRC, or executives.
What you'll learn:
- Numeric index vs letter grade
- Grade bands on the 0–950 scale
- When to use grade vs score
Two displays, one picture
| Display | Range | Best for |
|---|---|---|
| Security index | 0–950 | Fine comparisons between similar vendors |
| Letter grade | A–F | Fast triage and executive summaries |
Higher = stronger observed posture in our indexed data (fewer severe exposures).
Letter grade bands
| Grade | Score | Quick read |
|---|---|---|
| A | 850–950 | Strong; limited critical exposure |
| B | 700–849 | Good; monitor key findings |
| C | 550–699 | Mixed; review highs |
| D | 400–549 | Elevated risk; escalate |
| F | 0–399 | Severe aggregate risk in index |
Use grades to sort vendors. Use the numeric score when two vendors share a grade.

Quick answer
How is the OrgIntel360 security score calculated?
The security index runs from 0-950 and reflects observed posture in indexed data — a higher score means fewer severe exposures. It combines attack surface exposure, domain health, reputation signals, and severity-weighted findings.
The security index runs from 0-950 and reflects observed posture in indexed data — a higher score means fewer severe exposures. It combines attack surface exposure, domain health, reputation signals, and severity-weighted findings.
Letter grades map to score bands: A (850-950) is strong with limited critical exposure, B (700-849) is good, C (550-699) is mixed, D (400-549) is elevated risk, and F (0-399) is severe aggregate risk.
Use letter grades to quickly sort and triage vendors, and use the numeric score when two vendors share the same grade and you need a finer comparison.
