The Secure Data Layer
for Healthcare

Everything you need to encrypt PHI at the source and enforce access policies in real time. Seald Healthcare secures patient data at the record level, letting organizations decide who can access patient data, how, and under what conditions — even after it leaves your systems. If a vendor is breached or a contract ends, your data stays secure and unreadable.

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.

SDK-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.

Compliance vs. Security in Healthcare

Since 2009, over 846 million patient records exposed, with the average breach costing $9.77 million. This white paper examines why HIPAA compliance alone cannot prevent breaches and how a data-layer security approach closes the gap.

Write Access Policies in Plain English
with our AI Policy Studio

Define and enforce access policies in plain English. Seald Healthcare's AI Policy Studio translates natural language into cryptographically enforced rules that travel with the data, so administrators can write policies like “Only allow clinical staff to decrypt patient records during office hours” without configuring complex rule engines.

2

Encrypt and Set Policy

Data is encrypted at the source before it leaves your system. Access policies travel with the data, not the network.

3

Control After Sharing

Revoke access, update permissions, and audit usage in real time. Policies are enforced at decryption, not at the perimeter.
