Risk Engine by Veridium is an AI-driven component of their Identity Assurance Platform that provides continuous risk assessment and adaptive authentication capabilities to enhance security and user experience. It analyzes various factors including user behavior, device interactions, location, login velocity, browser data, WiFi network, and cell phone network to calculate real-time risk scores for authentication and continuous session monitoring. The Risk Engine collects a broad set of signals before and during authentication, using this data to determine access permissions, trigger reauthentication if risk levels increase during a session, and apply appropriate security measures based on the assessed risk. It supports different Identity Assurance Levels (IALs), allowing organizations to assign varying levels of security based on user roles, risk profiles, and regulatory requirements.
