Programmable Encryption
for Patient Data
Seald Healthcare eliminates plaintext PHI across healthcare workflows by encrypting patient data at the record level through our API and SDK. PHI remains encrypted wherever it moves or is stored, including across vendors, cloud environments, and AI systems. It decrypts only at authorized read time on an authorized device. Access remains policy-governed and revocable in real time, even after sharing.
The Problem
Once Your Patient Data Leaves Your Network, You Lose Control
Healthcare organizations share PHI across a growing network of vendors, cloud environments, and AI systems. Data is encrypted in transit, but when it reaches third-party systems it is decrypted, indexed, and processed in plaintext. Your vendor’s breach is not just your vendor’s problem. Once patient data leaves your network, a breach at a third party can expose your patients, your organization, and your reputation.

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. HHS guidance is explicit: encrypted PHI does not trigger 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.

with Marlow
Marlow enforces encryption and policy-governed access controls at the record level by analyzing your contracts, translating them into policies, and staging actions for your approval, including policy updates, key rotations, access changes, and session revocations. It verifies shared data through cryptographic signing, monitors decryption activity in real time, and provides visibility across vendors, cloud environments, and AI systems.

How It Works
Persistent Security
Across
Every System
and Workflow
Patient data moves across vendors, labs, billing platforms, and AI workflows every day. Seald Healthcare encrypts PHI at the source and ensures encryption and access policies follow the data wherever it goes, creating a unified, tamper-evident audit trail across every system and workflow.

One ciphertext, one policy, one audit trail, across every system
Tamper-evident audit log
sha-256 chain · liveStep 1 · Define Access Policies
Create policies that determine who can access patient data, under what conditions, and for how long. Configure permissions by role, team, device, or workflow.
Step 2 · Encrypt at the Source
PHI is encrypted the moment it is created. Encryption and access policies follow the data across vendors, billing platforms, labs, and AI workflows, ensuring patient data is never stored or shared in plaintext.
Step 3 · Maintain Persistent Control
Retain control over patient data even after it has been shared. Update or revoke access in real time and monitor activity through a unified, tamper-evident audit trail across every system and workflow.
Compliance vs. Security
in Healthcare
Healthcare does not have a compliance problem, it has a data security problem. Between 2009 and early 2026, more than 1 billion patient records have been exposed in reported healthcare data breaches. This white paper examines why HIPAA compliance does not equal security and how record-level encryption addresses a critical gap in how healthcare data is protected.
Tokenization vs. Encryption
Many healthcare solutions today rely on tokenization, replacing sensitive data with surrogate values while storing the original data elsewhere. This approach still depends on access to underlying plaintext data and introduces additional points of risk. Seald Healthcare uses true end-to-end encryption, ensuring PHI is never exposed in plaintext outside authorized environments and remains protected across systems, vendors, and workflows at all times.
Cloud Security Alone
Isn't Enough
Cloud providers like Amazon Web Services, Google Cloud, and Microsoft Azure operate under a shared responsibility model. They secure infrastructure, but you are responsible for protecting your data. Once PHI leaves your network, those protections no longer apply. Seald Healthcare adds a data security layer that encrypts PHI end-to-end, enforces access policies across organizations, and maintains control wherever data travels.
Why Now
Now is the Time for
Record-Level Security
Regulation is Catching Up
A recently proposed update to the HIPAA Security Rule, published in the Federal Register, would make encryption of ePHI mandatory by removing the longstanding addressable exception.
AI Breaks Perimeter Security
AI agents are autonomously accessing, processing, and transmitting PHI across organizational boundaries at machine speed. The data itself must be encrypted, with access control that persists wherever it travels.
Encryption Is About to Change Forever
Harvest now, decrypt later attacks are already underway. NIST has finalized post-quantum cryptography standards. Patient records do not expire. Seald Healthcare is post-quantum ready.
