Enforce policy at the protocol layer: no receipt, no run. Every high-risk call is gated by cryptographic receipts and epoch-based revocation.
Block at the HTTP layer, not just log.
Every decision is backed by a signed, audit-ready receipt.
Designed for Epic/Cerner ecosystems and regulated environments.
We build "governance rails" that sit in front of sensitive systems (FHIR servers, IDV services, core APIs). These rails enforce policy with cryptographic receipts (CDTs), epochs, and Merkle-based audit trails.
The result: high-risk operations only execute when there is a valid, provable receipt; otherwise the call is blocked before it reaches the backend.
We build enforcement rails that sit in front of your EHR, IDV, or core APIs. Every high-risk call is evaluated against policy, wrapped in a Cryptographic Data Totem (CDT), and either allowed or blocked before it reaches your system of record.
Epoch-based revocation lets you flip policy in milliseconds: bump an epoch and every stale receipt is instantly invalid. No code redeploys, no manual clean-up.
A rail that sits in front of your FHIR server. High-risk FHIR calls are gated on cryptographic receipts and epoch-based revocation. NO RECEIPT = NO RUN.
Identity verification rails that combine voice / document / device signals under a single policy and receipt.
Core receipt engine for non-healthcare systems requiring cryptographic governance.
A kill-switch rail that lets governance veto certain actions in real time, backed by receipts.
Every demo here is backed by a real enforcement rail. These are not slide-ware simulations; they are live endpoints hitting real rails and test backends.
Watch a FHIR call go from 200 → 403 when governance policy changes. This demo mirrors the v2.0 Hospital Rail POC we ship to hospital teams.
Demo runs against synthetic / sandbox FHIR data. No real patient data is used.
Generate and inspect Cryptographic Data Totems for sample policies and actions.

Request DemoYour app sends requests (e.g., FHIR calls, IDV operations, payments) to the governance rail instead of directly to your EHR or core system.
The rail evaluates policy, builds a Cryptographic Data Totem (CDT) that encodes purpose, retention, jurisdiction, and other signals, and binds it to the request.
The rail verifies the CDT against the current epoch and receipt store. If the receipt is valid and in-policy, the call is allowed and proxied downstream. If not, the rail returns a 4xx/5xx and the backend never sees the request.
Every decision is recorded as a receipt and rolled into a Merkle tree for integrity. Governance can bump epochs, revoke classes of receipts, and export audit data for compliance.
FHIR, AI in healthcare, and digital identity are all under heavier scrutiny.
Most 'governance' today is just logging; it doesn't actually stop a bad or out-of-policy call.
EHR and IDV platforms were not designed with native cryptographic policy enforcement; the rail layer closes that gap.
Procurement and compliance want provable controls, not just promises. Cryptographic receipts give them something concrete to audit.
We design for auditability from day one. Governance, not just dashboards.
Work with your CTO/CISO and key staff to map systems and identify where rails plug in.
Outcome: Architecture doc, risk map, and recommended rail placements.

No. The rail sits in the request path and can return 4xx/5xx before the request ever reaches your backend. In the Hospital Rail POC, you can see a FHIR GET call that returns 200, then after an epoch bump the same call returns 403 with a FHIR OperationOutcome. That is real enforcement, not a dashboard.
Yes. The Hospital FHIR Governance Rail is designed as a proxy in front of any FHIR-compliant backend. In a POC, we typically point it at a sandbox FHIR server first, then work with your team to connect to non-production Epic/Cerner environments.
Yes. The rail is a Python-based service that can run in your Kubernetes cluster, as a sidecar, or as a dedicated service in your VPC. We provide Docker images and deployment manifests as part of a paid engagement.
The rail is designed so that receipts store hashes and metadata rather than full PHI payloads. You control where the rail runs and where the audit store lives (e.g., your own Postgres). We work with your compliance team to align with your BAA and internal policies.
In most cases, your team can run the FHIR POC demo in under an hour, and we can stand up a tailored POC in 4–8 weeks depending on scope and environments.
We design fail-open vs fail-closed behavior with you, per use case. For some workflows you may want strict fail-closed behavior; for others, you may prefer a controlled fallback. The core patterns are documented, and we model them explicitly in policy.
Real technical resources. No marketing fluff.
Should you use a governance rail?
Where does the rail sit?
What's the overhead?
| Latency added: | ~8-15ms (receipt validation) |
| DB writes: | 1 per request (async batched) |
| Memory footprint: | ~40MB base + 2KB per receipt |
| Throughput: | 10K+ req/sec on 2 vCPU |
| Epoch bump: | Instant (in-memory flag flip) |
