The Problem
AI Agents Create PHI Exposure Risks Traditional Software Never Had
When an AI agent is granted access to a database, file system, or application, it often receives access to far more PHI than any individual task requires. Agentic workflows pass patient data between models, tools, APIs, and external systems in ways that are difficult to audit or control after the fact.
System-Level Access Is Too Broad
Traditional access controls operate at the application or database level. AI agents granted access to a system can often access every record inside it, not just the records relevant to the task they are performing.
AI Workflows Multiply Exposure Points
Agentic pipelines frequently move PHI across multiple models, vendors, tools, APIs, and processing environments. Each handoff creates another opportunity for unauthorized access or exposure.
Visibility Breaks Down Quickly
As AI systems call other systems, use tools, retrieve context, and exchange information, it becomes increasingly difficult to determine which records were accessed, by whom, and for what purpose.
Policies in Action
Examples of What You Can Enforce
AI workflows can expose far more patient data than an individual task requires. Seald Healthcare moves control to the record level, defining exactly which records and fields each agent can decrypt for a given task. Apply those controls to internal AI workflows, then extend them across external models, tools, APIs, and multi-agent systems.

The prior-authorization agent can decrypt only the coverage and eligibility fields for the request it is handling. Clinical notes do not decrypt for the agent.
An agent's decryption authority expires with its task. Retired workflows retain no standing decryption rights.
AI agents can decrypt only within the approved processing environment. A request from any other system or environment does not decrypt.
Orion Model Services can decrypt only the records and fields authorized for its inference workflow, from its registered environment with MFA verified. Its decryption authority can be revoked mid-workflow.
VectorPipe can decrypt only the fields authorized for its stage of the workflow. Remaining record fields do not decrypt for that system.
Halcyon Labeling Service can decrypt only the fields it is authorized to label, and is limited to two decryption sessions per hour.
When a Nimbus Orchestration workflow is retired, its decryption authority is revoked across every record it was authorized to access.
HIPAA Safe Harbor
A Breach of Properly Encrypted PHI Is Not a Reportable Breach Per HHS
If protected health information is lost, stolen, or accessed by an unauthorized party, properly encrypted data remains unreadable and unusable. Under HHS guidance, properly encrypted PHI is not considered unsecured PHI when the decryption key or process has not also been compromised, and therefore does not trigger HIPAA breach-notification requirements. That means a security incident does not automatically become a reportable breach. The result can be reduced breach liability, lower cyber insurance costs, and a dramatically different outcome for your organization.
“Protected health information (PHI) is rendered unusable, unreadable, or indecipherable to unauthorized individuals if one or more of the following applies: electronic PHI has been encrypted as specified in the HIPAA Security Rule… such encryption renders the breach notification provisions of the HITECH Act inapplicable.”
No Public Disclosure
No 60-day notification clock, no HHS portal listing, no press release.
Reduced OCR Exposure
Demonstrated safeguards reduce regulatory and enforcement exposure.
Lower Insurance Premiums
Record-level encryption may qualify for carrier premium credits.
FAQ
Frequently Asked Questions
What does Seald Healthcare do?
Seald Healthcare protects patient data itself, not just the systems around it. PHI remains encrypted at the record level wherever it is reviewed, processed, shared, or stored, and decrypts only at authorized read time under policy for an approved person, device, application, service, or AI agent.
Does Seald Healthcare have access to our patient data?
No. Seald Healthcare is zero-knowledge by design. We manage the cryptographic infrastructure and policy enforcement required to protect the data, but we cannot independently decrypt customer PHI.
What happens if a vendor or cloud environment is breached?
Seald Healthcare is designed so that compromising the environment storing the data does not, by itself, provide the authority required to decrypt the protected records. Patient data remains encrypted, and decryption still requires an authorized request that satisfies the active policy.
What does zero-knowledge mean?
Seald Healthcare manages key infrastructure separately from the patient data, but cannot independently decrypt customer PHI. Each data key is protected under key material controlled by your organization, keeping decryption authority separate from the systems storing or transmitting the data.
