Overview

Models

Foundation Models API

Foundation is our global model, as well as the underlying data that is used in the generation of that model. The outcome is a real time probability of exploitation, and the model uses the world’s largest repository of exploitation activity on vulnerabilities as the outcome measure. We have data about over 16,000 actively exploited CVEs.

EPSS Models API

EPSS is enterprise support for our public (and free) model, EPSS. More information as well as the free API can be found on www.first.org/epss. Here, we provide hourly updates and support for legacy EPSS models.

Radiant Models API

Lastly, we build Radiant models that are specific to enterprises. Reach out if you’d like to learn more: https://www.empiricalsecurity.com/contact.

Model Names and Keys

Every model has a permanent key that identifies it in API requests and responses. Keys never change, even when a model’s display name does. The Foundation V1 model’s key is global — the UI shows “Foundation V1”, but you request and read its scores as global. Likewise, EPSS model keys are epss_v3, epss_v4, and epss_v5.
