# How is Severity Score Calculated
Aikido provides a contextual, risk-based severity score from 0 to 100, offering 10× more granularity than traditional CVSS scoring (which is on a 0–10 scale). This allows for better prioritization and filtering.
Severity
Score
Critical
90 - 100
High
70 - 89
Medium
40 - 69
Low
1 - 39
### 1. Multiple Vulnerability Data Sources
We continuously monitor a variety of vulnerability feeds and databases, that provide baseline severity information and help establish initial severity scores. Databases include:
* Public vulnerability databases (e.g., NVD, GHSA,... | [See full list](https://help.aikido.dev/code-scanning/scanning-practices/external-vulnerability-databases-used-in-our-sca-engine))
* Operating system and vendor-specific advisories
* Our own Aikido Intel:
### 2. Contextual Severity Adjustments
To reflect actual risk more accurately, Aikido layers in additional context such as exploitability, environment, threat intelligence, and custom rules.
**Exploitability & Threat Intelligence:**
Severity can increase when there’s evidence of real-world risk:
* The vulnerability is actively exploited or appears on the CISA KEV list
* A public PoC exploit is available (e.g., on GitHub)
#### Business Context
Severity is adjusted based on the importance of the affected asset. Some example are:
* Production vs test environments
* Backend vs frontend code
* Whether the vulnerable code is reachable or executed
#### Customer Rules
You can further refine issue scoring by adding contextual information to your project
* Learn how you can improve the risk score for repositories and containers [here](https://help.aikido.dev/code-scanning/miscellaneous/improve-risk-scoring-for-repositories-and-containers)
#### Exploit Prediction (EPSS)
Aikido also supports EPSS-based prioritization to automatically downgrade or ignore vulnerabilities that are unlikely to be exploited in the next 30 days. This is optional and turned off by default, more info here: [use-epss-values-to-further-reduce-noise](https://help.aikido.dev/code-scanning/miscellaneous/use-epss-values-to-further-reduce-noise "mention")
