  1. Home
  2. Exploit Predictions

EPSS is a system that predicts the likelihood of a vulnerability being exploited in the wild. It uses machine learning models to predict the likelihood of a vulnerability being exploited in the wild. The system uses data from the National Vulnerability Database (NVD) and the Common Vulnerability Scoring System (CVSS) to train the models.
