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.

The Solution

The Encrypted Data Layer for Healthcare

Seald Healthcare encrypts PHI at the source and ensures encryption and access policies travel with the data across EHRs, vendors, payers, analytics platforms, and AI systems. You control who can decrypt your data, under what conditions, for how long, and from which devices, with the ability to revoke access at any time, even after sharing. No intermediary, including Seald Healthcare, can access your plaintext data.

End-to-End Encryption

PHI is encrypted on the sender's device and only decrypted by authorized recipients. No intermediary, including Seald Healthcare, can access plaintext data.

Persistent Access Policies

Control who can access data, from which devices, and during which time windows. Revoke or update permissions at any time, even after data has been shared.

Tamper-Evident Audit Logs

Every access, denial, and policy change is logged with cryptographic integrity. Logs cannot be altered without detection.

Developer-First Integration

Seamlessly add encryption to your existing applications or workflows. No changes to how you currently operate are required.

Automatic Key Management

Encryption keys are issued, rotated, rewrapped, and revoked automatically. No cryptography expertise is needed from your team.

Group and Role-Based Access

Assign permissions to care teams, departments, or roles. Access updates automatically as group membership changes.

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.

Step 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.

New Resource

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.
