Understanding your security score

How the A–F grade is calculated and what each severity level means.

Understanding your security score

We convert 30+ individual checks into a single score and grade so you can see your overall posture at a glance.

The grade scale

| Score | Grade | Meaning | |-------|-------|---------| | 90–100 | A | Strong posture. Rare edge cases only. | | 80–89 | B | Good posture. A few fixable gaps. | | 70–79 | C | Meaningful gaps. Prioritise fixing this quarter. | | 60–69 | D | Attacker-attractive. Fix within 30 days. | | 0–59 | F | Active risk of breach. Fix immediately. |

Severity levels

  • Critical — active exposure or data leak. 24-hour SLA.
  • High — serious misconfiguration or missing control. 7-day SLA.
  • Medium — hardening that should exist. 30-day SLA.
  • Low — best-practice finding. Fix when you can.
  • Info — informational only. No action required.

Hero finding

At the top of the overview page we highlight the single most impactful finding — the one where fixing it will most improve your score and block the most likely attack vector. When you fix the hero finding, the next-most-important one takes its place.

Scoring algorithm

Starting at 100, we subtract points for each open finding:

  • Critical — 25 points
  • High — 15 points
  • Medium — 5 points
  • Low — 1 point

Suppressed/accepted risks do not count against the score but are listed separately.

Score trend

On the overview page, the score-over-time chart shows the last 12 months. Green deltas are improvements, red deltas indicate new findings. We snapshot once per day per asset.
