Secure Agentic AI Workflows

Let AI Agents Access Only What They Are Authorized to See

AI agents increasingly ingest and act on PHI, creating new exposure risks that traditional security models are not designed for. Seald Healthcare provides a cryptographic layer that allows AI systems to process only the data they are explicitly authorized to access, keeping PHI protected inside every agentic and LLM-powered workflow.

The Problem

AI agents create PHI exposure risks that did not exist in traditional software

When an AI agent is given access to a data system, it often receives access to far more PHI than any individual task requires. LLM-powered tools ingest context windows full of patient data. Agentic pipelines pass PHI between models, tools, and APIs in ways that are difficult to audit or control after the fact.

AI models and agents that ingest PHI can inadvertently memorize, surface, or leak patient information in unrelated outputs.

Agentic pipelines often pass PHI between multiple AI systems and third-party APIs, each of which represents a new exposure point.

Traditional access control operates at the system level. AI agents that are granted database access can read any record, not just the records relevant to the task.

Regulators are beginning to scrutinize AI use in healthcare, and organizations that cannot demonstrate granular PHI control in AI workflows face growing compliance risk.

How Seald Healthcare Solves It

Cryptographic guardrails for PHI inside AI pipelines

Seald Healthcare enforces access at the record level so AI agents can only read the data they are explicitly authorized to process.

Record-Level Access for AI Agents

Rather than granting an AI agent access to a database or file system, Seald Healthcare grants access to specific encrypted records. The agent can decrypt only what it is authorized to process for a given task.

PHI Isolation Across Multi-Agent Pipelines

In workflows where multiple AI agents pass data between each other, Seald Healthcare ensures each agent receives only the PHI relevant to its function. Downstream agents cannot access upstream context they are not authorized to see.

Full Audit Trail for AI Data Access

Every record decrypted by an AI agent is logged with the agent identity, task context, timestamp, and cryptographic signature. Demonstrate exactly what data your AI systems touched and when.

Dynamic Policy Updates for Evolving AI Workflows

As your AI pipeline grows and changes, update access policies in real time without redeploying the AI system. Revoke a data access grant instantly if a model or workflow is deprecated or compromised.
