Why Seald Healthcare
The Current Healthcare Security Model Leaves Data Vulnerable
Perimeter and infrastructure security protect your network, not the data itself. Encryption keys are often stored with the data or accessible to the same systems using it. Once PHI is decrypted or shared, the originating organization loses direct cryptographic control over how it is accessed.
Cloud Infrastructure
Stolen credentials can expose every record the system is authorized to decrypt. No individual record encryption.
Data in Transit
Third parties can immediately decrypt and store patient data in plaintext.
Third-Party Vendor
Plaintext Storage
Data originator has no direct cryptographic control after delivery. No tamper-evident audit log.
Seald Healthcare Encrypts Patient Data at the Record Level
Persistent, zero-knowledge, record-level security that stays attached to every patient record wherever it is reviewed, processed, or stored. Patient data decrypts only at authorized read time under policy, preserving cryptographic control even after it is shared.
Cloud Infrastructure
Record-level encryption. Credentials alone cannot decrypt every patient record.
Data in Transit
Each record remains encrypted while access policies continue to govern decryption.
Third-Party Vendor
End-to-End Encrypted
The data originator retains cryptographic control. Patient data remains encrypted until policy-authorized decryption is permitted.
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.

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
Third-Party Systems
Vendors 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 at authorized read time 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, since 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 hold ciphertext
Vendors can read data only where policy-authorized decryption is permitted.
From Contracts
to Cryptographic Enforcement
Healthcare Operates on Trust.
It Needs Cryptographic Enforcement.
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.
