GUARDIAN HEALTH BY HEARTH & ALLOY
The AI Control Plane for Healthcare
Patent-pending Three-Gate architecture ensures AI systems only receive data your organization has classified, policy-checked, and authorized. Start with a free readiness assessment for your team.
Executive Summary
Healthcare organizations want AI. Consumer AI can't see PHI safely.
Guardian Health is a production-ready AI Control Plane.
Three sequential, irreversible controls (Data Reality; Purpose & Authority; Risk-Based Routing) ensure that AI models, tools, and external providers receive only data your organization has classified, authorized, and (when required) transformed. Every decision is captured in an immutable audit trail with 7-year retention.
Architecture
The Three-Gate Pipeline
Sequential. Irreversible. Auditable. Every AI request passes through all three gates before any model sees any data.
What is this data, really?
Multi-signal detection identifies sensitive content before it leaves your environment: HIPAA identifiers, healthcare-specific codes, and domain-extensible markers for other regulated industries.
- • File screening across common document and image formats
- • Tuned for healthcare vocabulary to reduce false positives
- • Layered detection with graceful fallback
Is this user allowed to do this?
Policy evaluates user role, task context, and data classification together. Sensitive values are transformed while meaning is preserved, and an independent verification layer confirms the request is safe before anything is routed.
- • Downstream tools can be invoked without exposing raw values
- • Test policies safely before production rollout
- • Each decision is captured for audit replay
Where is it safe to send?
A composite risk score determines which approved model or provider a request is eligible for, or blocks the request entirely. Organization-scoped allowlists, health-aware routing, and concurrency controls run underneath.
- • Works with major commercial and on-prem model providers
- • Per-tenant controls on throughput and capability
- • Full lineage from request to response

- • Policy simulation and anomaly detection
- • Context-aware help (knows your current page)
- • Weekly digest with compliance insights
Admin Experience Modes
Managed, Standard, Advanced, Assessment tiers. Admins see only the surface area they need, from one-page scorecard to full policy engine.
- • Industry selection during onboarding
- • Navigation filtering per mode
- • Backend access control middleware
How It Works
Assessment first. Platform second.
Measure the team
Admin signs up, invites the team, and employees complete the free readiness assessment (three modules, about 30 minutes per employee). Individual scores stay private; an anonymized organizational scorecard unlocks at five completions.
Close the gaps
Training modules are available covering each readiness category. Employees complete the content relevant to their gaps; baseline scores stay locked and improvement is tracked separately so the numbers your CISO sees remain honest.
Turn on the platform
When you're ready, turn on enforcement where your team actually works: the AI Chat & Task Library, the browser extension, or your existing applications via the API gateway. Same three gates, same audit trail, now enforcing on real requests instead of assessment scenarios.
