Exaforce Multi-Model AI is a security operations platform that uses a multi-model architecture combining Semantic, Behavioral, and Knowledge Models to provide deterministic and explainable AI-driven security operations. The platform addresses detection, triage, investigation, and response workflows for security operations centers. The Semantic Model builds and maintains relationships between identities, resources, and actions, creating a structured map of the environment for contextual reasoning. The Behavioral Model establishes baselines for normal activity across users, identities, resources, and devices, then quantifies deviations using multi-dimensional anomaly scoring that evaluates factors including location, time of day, entity attributes, and associated risk. The Knowledge Model combines LLM reasoning with curated external intelligence, historic decisions, and business rules to understand application, infrastructure, and policy operations. It breaks down high-level intents into precise checks across the Semantic and Behavior layers and provides clear summaries with supporting evidence. The platform provides governed reasoning with explicit data scope, curated context, and full logging for auditable results. It integrates with existing SIEM, EDR, and IDP stacks to reduce false positives and investigation times in cloud and SaaS environments.
