The EPSS SIG has been working diligently updating the powerful machine learning model behind the vulnerability prediction scores. Supported by the growing SIG of 180 people from around the world, and across different industries, EPSS is expanding and improving month over month.

The outcomes of all this is that the new model was released on March 7th, 2023. Leveraging increased support from additional data providers, and improved machine learning capabilities, the EPSS model enjoys significant performance improvement over the previous model. In addition, a complete research paper has been written describing these new techniques and insights, which can be found at https://arxiv.org/abs/2302.14172. The EPSS chairs, Sasha Romanosky and Jay Jacobs, look forward to sharing these, and other exciting results, at the FIRST Conference in Montréal in June 2023.
