Enterprise immune systems use machine learning and AI to provide self-learning, self-defending networks for organizations. Darktrace's Enterprise Immune System uses unsupervised machine learning across 350+ data features to establish a "pattern of life" for every user, device, and their relationships to autonomously detect threats without predefined rules. It has detected over 63,500 in-progress threats across many organizations, completing the immune system model with real-time responses. Customers praise Darktrace for its unique ability to detect even unknown threats and insider behaviors.
