Security & trust
Safe to adopt in a clinical setting.
Two distinct things, both engineered in: guardrails that keep the AI safe on every turn, and security that protects your patients’ data.
AI guardrails
Guardrails, built for the AI
The layers that keep the AI itself safe on every turn — engineered in, not bolted on. (Data security is separate — see below.)
The full picture — how each guardrail works — in a 30-minute conversation.
Security & data
Your data, handled to your standard
Separate from the AI’s guardrails — this is how your patients’ data is protected, isolated and auditable.
De-identified by design
The patient surface never needs identifiers to work; pseudonymisation is built into the pipeline.
Tenant-isolated
Row-level isolation between institutions and encounters — enforced at the data layer, not just the app.
Full audit trail
Every reveal, edit and sign-off is logged as an auditable event — the paper trail your governance board asks for.
Deployment & residency options
Hosting region, data-handling and integration scope agreed in the security review, to your requirements.
