MagenTrust provides continuous identity assurance for human-operated clinical workstations and trusted machine-to-machine connections across medical IoT, APIs, and agents. MagenTrust runs inside the customer's perimeter and supports fully air-gapped deployment, including isolated hospital and defense networks. No data leaves the environment. Behavioral signals verify the clinician behind a UI session, while policy APIs and MagenMCP govern device, service, and agent actions before execution. PASS, CHALLENGE, or INTERRUPT decisions run alongside existing IAM, EHR access controls, and badge systems inside segmented or air-gapped networks with no stored biometrics and no data egress.
