The technical blueprint: The three-plane model

To achieve this state of continuous audit readiness, we organize our architecture into three distinct planes. This separation clarifies the distinction between technical enforcement and regulatory accountability. 1. The data plane covers how clinical or device data moves through the system to deliver its medical purpose — whether that is physiological telemetry from a wearable or medical images for diagnostic analysis. In Google Cloud, this plane handles functional boundaries and ensures data integrity through encryption at rest and in transit.

We use Customer Managed Encryption Keys (CMEK) and Key Access Justifications to ensure the manufacturer retains ultimate control over decryption events, a critical requirement for HIPAA and GDPR compliance. 2. The control plane is the governance layer. It defines identity, network boundaries, and configuration constraints. In the 2026 architecture, the control plane uses Zero Trust principles.

Instead of relying on a network perimeter, access is granted through Identity Aware Proxy (IAP) after evaluating the user's identity, device security posture, and context. We also use the Organization Policy Service to programmatically prevent non-compliant configurations, such as the accidental creation of public data buckets. 3. The evidence plane is where technical operations meet regulatory proof. It captures immutable audit trails, build attestations, and monitoring history.

By using tools like Binary Authorization and Artifact Registry, we can mathematically prove that only code that has passed all security and validation gates is allowed into production. This plane generates the software bill of materials (SBOM) and provenance metadata required by the FDA.
