# Risk Scores and Ratings
> Compare Webacy 0-100 numerical risk scores and A+ to F letter-grade ratings, and learn when to use each for automated policies or human-facing interpretation.
Every Webacy analysis produces one or more **risk scores** that quantify the relative risk of an entity. Depending on the entity type, these scores may also be translated into a standardized **letter-grade rating**, making complex blockchain risk easier to interpret at a glance.
While the methodology used to calculate each score varies by entity type, every score follows the same fundamental principles and is designed to provide consistent, explainable, and actionable risk intelligence across the platform.
## Risk Scores
Risk scores are numerical values that represent the relative risk of an entity on a scale from **0 to 100**. Every score is generated by combining hundreds of individual risk factors through entity-specific weighting and scoring methodologies. Depending on the entity, these methodologies may incorporate real-time monitoring, structural analysis, historical behavior, financial metrics, governance characteristics, and compliance signals before producing a final composite score.
Unlike binary pass/fail systems, a numerical score provides greater precision for monitoring changes over time, comparing entities, and building automated policies.
Across Webacy, **higher scores always indicate higher risk**.

Risk scores are intended to be machine-readable and are commonly used by policy engines, APIs, automated workflows, alert thresholds, AI agents, historical monitoring, and more.
## Letter Grade Ratings
For supported entity types, Webacy converts numerical risk scores into standardized letter-grade ratings.
Ratings provide a concise summary of overall risk without requiring users to interpret individual numerical values.
| Rating | General interpretation |
| -------- | ---------------------- |
| A+ to A- | Low observed risk |
| B | Moderate risk |
| C | Elevated risk |
| D | High risk |
| F | Severe or unacceptable |
The exact mapping between scores and ratings depends on the entity type and the methodologies used to evaluate that asset.
## Explainable by Design
Every Webacy score is designed to be explainable.
Rather than acting as a "black box," scores are backed by the underlying risk factors, detection engines, and supporting intelligence that contributed to the final result. This enables developers, analysts, institutions, and AI systems to understand not only **what** the score is, but **why** it was assigned.
## Scores Evolve
Blockchain risk is dynamic.
As new information becomes available, risk scores may change to reflect new blockchain activity, protocol upgrades, governance changes, market conditions, emerging threats, or newly discovered relationships between entities.
For this reason, Webacy scores should be viewed as **continuous assessments rather than permanent labels**.
