SGNL is a continuous identity and authorization platform that eliminates standing privilege and makes real-time, context-aware access decisions for both human users and AI agents. It sits at the center of an enterprise IAM architecture, dynamically adapting permissions as conditions change and revoking sessions in real time. SGNL is built on the OpenID Shared Signals Framework (SSF) and the Continuous Access Evaluation Profile (CAEP), ingesting context from identity providers, HR systems, and security tooling to enforce zero standing privilege across cloud and infrastructure. Its Public API v2 (Access Service) exposes REST/JSON access evaluation, asset and principal search, directory query, and provider-hook routing.
