A secure, governed transport layer that moves clinical and AI data with speed, reliability, and full traceability.
Download Full Architecture DocumentFour planes working together — Integration, Communication, Intelligence, and Execution — to deliver governed connectivity between clinical systems, AI agents, and 26+ sibling applications.
Deploy new system connections in days, not months.
AI workloads are isolated from clinical data paths.
Every data movement is traced, audited, and compliant.
HelixCare exercises a single synthetic patient journey end-to-end across every Symphonix Health sibling, the BulletTrain HIE, the Nexus A2A agent fabric, and the GHARRA federation — verified at W11 with zero emulators, zero fixtures, zero mocks.
A representative HelixCare journey from 999 dispatch through to community follow-up. Every cross-system handoff is a real FHIR or Nexus A2A message, mediated by the BulletTrain HIE, audited at the boundary, and governed by GHARRA trust policy.
The Symphonix Bridge SDK is the one boundary across which clinical and operational data flows. Inside it: 26+ real sibling applications, no internal mocks. Outside it: real third-party systems via standards. Below: the retired symphonix-emulator-kit and the twelve real services that replaced it.
From ingestion to delivery, every step is governed, traced, and auditable.
Data enters via Fast Healthcare Interoperability Resources (FHIR), Health Level 7 version 2 (HL7v2), Clinical Document Architecture (CDA), X12, Digital Imaging and Communications in Medicine (DICOM), or Application Programming Interface (API).
Bevan Large Language Model classifies content as clinical, operational, or AI-bound — determining the correct routing path.
The SignalBox control plane directs data to the right destination with governance checks applied at every decision point.
Data arrives at clinical systems, AI models, or analytics platforms — fully traced with a complete audit record.
Every layer of the platform enforces security and governance by design, not as an afterthought.
Role-based access with 6 Identity and Access Management (IAM) groups and per-agent authentication. Every request is authenticated and authorised before execution.
Hash-chained transparency ledger — every action recorded and verifiable. Tamper-evident by design, with cryptographic proof of integrity.
Three-layer patient data detection blocks sensitive information at the boundary. Data is classified, filtered, and protected before it leaves the transport layer.
External AI models never see patient data. Bevan handles clinical reasoning locally, ensuring sensitive information stays within governed boundaries.
Choose the deployment model that matches your data sovereignty requirements and infrastructure strategy.
Hosted within your national data boundaries. Full platform, fully managed, with no data leaving the jurisdiction.
BulletTrain in your cloud, AI services federated. Keep clinical data on your infrastructure while accessing AI capabilities securely.
Full platform within your data centre — no external dependencies. Complete control over every component and data flow.
Healthcare systems demand absolute reliability. Every component is designed for resilience and recovery.
Automatic failover prevents cascading failures. When a downstream service degrades, the circuit breaker isolates the fault and routes around it.
Kafka-backed event bus with dead-letter recovery. Every event is persisted and replayable — no data is ever lost, even during outages.
Prometheus metrics and real-time observability across every microservice. Alerts fire before problems become incidents.
Emergency requests are never blocked — the absolute healthcare safety constraint. When lives are at stake, the system guarantees access.
Includes detailed system diagrams, security controls, deployment topologies, and compliance mappings.
