The challenge
Severity alone does not tell teams what to fix first. High-CVSS vulnerabilities can be low operational risk, while medium-severity issues can be actively exploited and urgent.
How ARIANNA prioritizes
ARIANNA’s pre-triage engine combines severity with exploitability intelligence and context.
- CVSS severity for initial classification
- KEV evidence for known active exploitation
- Exploit maturity (PoC, verified, weaponized)
- EPSS probability for near-term exploitation likelihood
- Attack vector relevance to the target device
Outcome
Vulnerabilities are automatically grouped into high and low priority queues so teams can focus triage effort where risk is highest.
What remains manual
ARIANNA provides decision support, not auto-remediation. Security teams still own risk acceptance, status decisions, and mitigation planning.
Operational value
This model reduces manual triage overhead, improves remediation sequencing, and supports policy-aligned vulnerability management at scale.
