Local Models
Local models are trained on your environmental and telemetry data to support your enterprise’s decision making.
Global Models
Global models combine real-time exploitation telemetry with EPSS predictions to accurately depict exploitation.
EPSS Model
Empirical builds and maintains the world’s only public machine learning model in cybersecurity, EPSS.
How It Works
The platform supports Empirical's global and local models. Our global model, trained on ~2 million exploitation events, captures attacker behavior across the internet. Local models, trained on your environment's telemetry, capture more targeted attacks. The two models work together to surface the vulnerabilities most likely to be exploited in your infrastructure.
Effort, Coverage, and Efficiency
CloseAll Published Vulns (CVEs we could prioritize)
Effort
Measures the relative workload as the proportion of vulnerabilities prioritized out of all the possible CVEs:
True Positives + False Positives / Everything
Coverage
Measures how well our strategy covers the vulnerabilities we prioritized from all vulnerabilities that show exploitation activity (False Positives are prioritized without any exploitation activity observed):
True Positives / True Positives + False Positives
Efficiency
Measures how accurately our strategy focuses on vulnerabilities that have exploitation activity (False Negatives are not prioritized and exploitation activity is later observed):
True Positives / True Positives + False Negatives
