Secure and Control
Patient Data, Even After
It Leaves Your System
Seald Healthcare gives you full control over your patient data by encrypting PHI at the source and eliminating plaintext exposure. Set, enforce, and revoke access in real time, even after data is shared, without disrupting workflows.
The Problem
Healthcare’s Data Breach Problem
PHI is encrypted in transit but stored and processed in plaintext across EHRs, vendors, payers, and analytics platforms. Once data leaves your environment, you lose visibility and control. If any of these systems is compromised, patient data is fully exposed.

Why Now
Now is the Time for Data Layer Security
Breaches Are Accelerating
502 breaches in 2025, up 112% year-over-year. Over 80% originate from third-party vendors. The problem is accelerating, and current solutions are not working.
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.
How It Works
Persistent Security Across
Every System
Patient data moves across EHRs, 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.

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 EHRs, 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 900 million patient records have been exposed in reported healthcare data breaches. This white paper examines why HIPAA compliance does not equal security and how data-layer encryption addresses a critical gap in how healthcare data is protected.
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 environment, 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.
Tokenization is Not 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.
