Grade Scale

QR Scores are mapped to action-oriented grades that communicate the resilience posture and recommended response.

Grade definitions

Score Range	Grade	Meaning	Risk signal
90–100	Sustain	Highly resilient; maintain current practices	Low risk; strong infrastructure posture
75–89	Optimize	Strong foundation; fine-tune for excellence	Below-average risk; minor improvements possible
60–74	Strengthen	Adequate resilience; build on existing capabilities	Moderate risk; specific areas need attention
40–59	Improve	Focus areas identified; targeted improvements needed	Elevated risk; material gaps exist
0–39	Prioritize	Action required; address foundational gaps	High risk; significant infrastructure concerns

Using grades in risk assessment

Grades provide a quick classification, but the pillar breakdown offers more actionable insight:

• A score of 62 (“Strengthen”) with a Device Health pillar at 35 tells a different story than one with all pillars at 60–65; use Get Pillars to see the breakdown
• The trend matters as much as the absolute score; a 55 trending up over 90 days is different from a 55 trending down; use Get Trend to see the trajectory

Grade in the API

The grade is returned as a string in the Get Score response:

  "scoreDate": "2026-03-18",
  "score": 84,
  "grade": "Optimize"
