Healthcare
Sovereign, provable AI that keeps ePHI in your walls
Clinical and administrative teams have AI pilots that could cut documentation load and speed prior authorization, but they stall the moment ePHI meets a language model: the data cannot leave your environment, access has to stay minimum-necessary, and compliance has to prove exactly who touched which record and why. NuDay keeps protected health information encrypted and in your control, binds every access to a verified clinician, and produces the per-access evidence your teams need.
ePHI never sits in plaintext for a breach to take.
Every record access reaches review tied to a verified identity and a signed, tamper-evident trail.
Why it stalls
Why healthcare AI stalls in review
The pilots work. What blocks them is four things privacy and security cannot get comfortable with, and what changes each conversation:
ePHI leaks into the model context and the agent's memory. NuDay encrypts the agent's data layer, so a breach yields unreadable ciphertext.
Agents hold standing access to the EHR and clinical systems, well beyond minimum necessary. Zero-credential, on-behalf-of access, scoped and short-lived, bound to the clinician the agent acts for.
No way to prove to compliance or an OCR investigator who accessed which record, and why. A per-access, tamper-evident audit ties every read and write to a verified identity.
An agent could drift into unauthorized clinical advice or actions. Guardrails and tools are cryptographically signed, so an agent cannot rewrite its own limits and unauthorized actions do not run.
Data sovereignty
Keep PHI in your environment
The safest place for protected health information is inside your own walls. NuDay is built so ePHI never has to leave them.
PHI stays put
Run on-prem or in your own VPC so ePHI is never sent to a third-party cloud or an external LLM.
You hold the keys
Bring your own keys on hybrid; on-prem keeps key custody entirely in-house.
The model stays yours
Run the LLM on-prem so PHI and the reasoning over it never leave your environment.
The evidence
The evidence your frameworks ask for
NuDay does not grant compliance. It produces the concrete, provable evidence your teams and assessors map to each requirement.
HIPAA Security Rule
Encryption of ePHI at rest, least-privilege access control, and audit controls, produced as evidence for the technical safeguards rather than asserted.
Minimum necessary
Access is bound to the clinician and scoped to the task, so an agent sees only the records a workflow actually requires.
HITECH and breach notification
Because ePHI is ciphertext at rest, a compromised store yields unreadable data, which changes the breach calculus for your team.
42 CFR Part 2
Heightened protection for substance-use records through per-record encryption and access bound to explicit authorization.
HITRUST
Cryptographic chain-of-custody evidence that only authorized agents accessed specific patient records.
EU AI Act, high-risk systems
Tamper-evident logging and cryptographically bound guardrails for high-risk medical AI, so behavioral limits cannot be rewritten at runtime.
What review gets
What privacy, security, and compliance get
Not a promise that the AI is safe, but the evidence to decide for themselves.
Per-access provenance
Which record was accessed, by which agent, under which clinician's authority, on every action.
ePHI encrypted at rest
Memory, RAG, and shared context are ciphertext, per record, with independent keys.
Minimum necessary, enforced
Scoping is cryptographic, not a policy an agent can be talked out of.
