Why Seald Healthcare
AI Is Disrupting Today’s Security Model
Perimeter and infrastructure security protect the systems around patient data. As AI agents, applications, and vendors gain legitimate access to PHI, each one becomes another place plaintext can be exposed.
Cloud Infrastructure
Healthcare security depends on trusted systems with access to plaintext PHI. A compromised credential, application, vendor, or AI agent exposes everything.
Data in Transit
Encrypting data in transit and at rest is no longer sufficient. A compromised credential, application, or vendor turns trusted access into plaintext exposure.
Third-Party Vendor
Plaintext Storage or Usage
Once shared, patient data lives in systems you can no longer see or control. Their breach becomes your breach.
Seald Healthcare Encrypts Patient Data at the Record Level
Persistent, zero-knowledge, record-level security stays attached to every patient record wherever it is stored, accessed, or shared. Patient data decrypts only during authorized use under policy, so you keep cryptographic control after it leaves your environment.
Cloud Infrastructure
A zero-knowledge, centralized key management system tied to policy. Credentials alone cannot decrypt a patient record.
Data in Transit
Encryption and access controls travel with the record across every system, vendor, and workflow.
Third-Party Vendor
Encrypted at the Vendor
Patient data decrypts only during authorized use, under your policy.
AI and the Attack Surface
How AI Expands the Attack Surface
Each new AI system is another identity, another integration, and another path to plaintext PHI. Here is where the exposure grows, and what record-level security changes.
AI Agents With Credentials
The Risk
Every AI agent and automated workflow acts with its own credentials. Compromise one, and an attacker can read everything that agent can reach.
With Seald Healthcare
Each agent decrypts only the records its policy allows, and its access can be revoked in real time.
Prompt Injection
The Risk
Hidden instructions in a document, email, or record can manipulate an AI system into disclosing data. OWASP ranks it the top security risk for LLM applications.
With Seald Healthcare
A manipulated agent is still limited to the records it was authorized to decrypt, and every decryption is logged.
Third-Party AI Vendors
The Risk
PHI sent to outside AI tools and model providers usually arrives in plaintext, beyond your control.
With Seald Healthcare
Records stay encrypted at the vendor and decrypt only during authorized use under your policy.
Shadow AI
The Risk
Staff paste patient data into AI tools that were never approved, often without anyone knowing.
With Seald Healthcare
Decryption is limited to approved devices and conditions, and every access is logged, so PHI is harder to move and easy to trace.
Before AI Can Be Deployed
Chain of Custody Comes First
To deploy AI safely, you have to know who or what accessed every record, what changed, and under which policy. Seald Healthcare records every access, change, addition, and deletion in a tamper-evident audit trail, so you have a verifiable chain of custody before AI ever touches patient data.
How Seald Healthcare Works
One Security Model Wherever Patient Data Goes
Seald Healthcare applies the same record-level security model whether a person reviews a record, software or AI processes it, or it is shared with another organization. There are three ways to deploy it, depending on the workflow.
Human Review
Secure Portal Access
Give authorized users access to protected patient records through a secure browser-based portal without requiring a native integration.

Software & AI Agents
Native Integration
Use Seald Healthcare’s API and SDK to let applications, vendors, and AI agents process patient data while limiting plaintext to authorized use.
Best For
- Claims Processing
- Eligibility
- AI Workflows
- Analytics
- Clearinghouses
- EHR Integrations
Business Continuity
Protected Storage
Keep patient records encrypted across databases, cloud storage, archives, backups, and disaster recovery while preserving authorized access and restoration.
Best For
- OneDrive
- Google Drive
- S3
- Databases
- Cloud Storage
- Archives
- Immutable Backups
- Disaster Recovery
Rolling Out Native Integration
Secure Portal Access and Protected Storage need no vendor cooperation. Native Integration rolls out in two phases.
Phase 1 · Day One
Secure Your Own Environment
No vendor action needed.
- Encrypt files on write in OneDrive and Google Drive
- Per-person access controls by device, hours, location, and more
- Step-up verification for unusual access
- Cryptographic signing on every file you send
- Exportable, tamper-evident audit trail
Phase 2 · Native Integration
Extend Seald Healthcare to Your Vendors
Each vendor integrates once, guided by our forward-deployed engineers.
- End-to-end encryption to each vendor
- Vendors verify your signatures automatically
- No change to their workflow
- Rolls out vendor by vendor
Native Integration
Where Seald Healthcare Sits,
and What It Protects
Native Integration deploys at the egress point where patient data leaves your environment. Seald Healthcare encrypts PHI at the record level before it reaches third-party systems, while your EHR, integrations, and downstream workflows remain unchanged.
Inside Your Network
Your EHR / EMR
Epic, Oracle Health, Athenahealth, eClinicalWorks, and more.
Your EHR remains your system of record. Seald Healthcare does not replace it or require EHR vendor cooperation.
The Egress Point
Seald Healthcare deploys through your integration engine, FHIR API, HL7 feed, SFTP workflow, API, or outbound file process.
As PHI exits, Seald Healthcare encrypts it at the record level and applies policy-governed access controls that remain attached to the data.
Outside Your Network
Vendors and AI Agents
Vendors and AI agents receive data through the same workflow, format, schedule, and connection they use today. Protected fields or files remain ciphertext unless policy-authorized decryption is permitted.
Plaintext Exists Only During Authorized Use
The data remains encrypted, policy-governed, and revocable even after it is shared.
Native Integrations
HL7, FHIR, X12, APIs, and Integration Engines
Seald Healthcare integrates with HL7, FHIR, X12, APIs, and integration engines while preserving existing workflows. Sensitive values remain encrypted at the record level and decrypt only during authorized use under policy.
File Transfers
SFTP and Batch Files
Seald Healthcare encrypts files before they are written to SFTP or other file-transfer locations. Vendors retrieve files using the same credentials, schedule, and automation they use today. What sits on the server is ciphertext, not plaintext PHI.
Split Custody
No Single Party Can Produce Plaintext Alone
Seald Healthcare is zero-knowledge by design. We manage the key infrastructure but cannot decrypt your PHI. The keys we manage are themselves encrypted under a key you control.
You hold the data
Patient data remains encrypted in your systems, vendor workflows, and shared environments.
Seald Healthcare manages the key infrastructure
Keys are issued, rotated, rewrapped, and revoked automatically under your policies. Key release is governed at decrypt time.
Vendors and AI agents hold ciphertext
They can read data only where policy authorizes decryption.
Policy Studio · Powered by Marlow
Your Contracts, Enforced at the Record Level
Policy Studio, powered by Marlow, turns BAAs, vendor contracts, security requirements, and organizational policies into enforceable record-level access controls. Marlow drafts and validates each policy for review and approval. Once approved, Seald Healthcare enforces it cryptographically on every decryption request.

Applies To
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
