Autonomous Threat Containment for EHR Systems

Electronic Health Record systems are the backbone of modern healthcare delivery. They hold the most sensitive patient data - medical histories, prescriptions, insurance records, Social Security numbers - and they're online 24/7. That makes them a prime target.

Traditional security tools treat EHR systems like any other enterprise application. They aren't. EHR platforms like Epic, Cerner, and MEDITECH have unique architectures, proprietary protocols, and strict uptime requirements that make conventional intrusion detection unreliable and incident response dangerously slow.

Why EHR Systems Need Autonomous Security

When a threat actor gains access to an EHR environment, the window between initial compromise and data exfiltration is shrinking. Industry data shows the average dwell time in healthcare breaches dropped to 4.2 days in 2025 - down from 18 days just two years prior. Human-only response teams simply can't keep up.

SecUnit's containment agent operates at machine speed. When our detection layer identifies anomalous behavior - lateral movement between clinical workstations, unusual database query patterns, credential stuffing against patient portals - the containment agent can isolate affected segments in under 200 milliseconds without disrupting clinical workflows.

How It Works

The containment agent doesn't rely on static rules or signature matching. It builds a behavioral model of normal EHR access patterns: which users access which records, from which devices, at which times. Deviations trigger graduated responses:

• Low confidence - Alert the security team with full context and recommended actions
• Medium confidence - Restrict the session to read-only access while investigation proceeds
• High confidence - Isolate the session, preserve forensic evidence, and notify the SOC

Each action is logged with full provenance for HIPAA audit requirements. Every containment decision can be reviewed, reversed, and used to train future responses.

Results

In our first six months of production deployments, the containment agent has:

• Contained 847 confirmed threats across 12 health systems
• Achieved a mean time to containment of 180ms
• Maintained 99.97% clinical workflow availability during active containment
• Generated zero false-positive containment actions that disrupted patient care

The days of choosing between security and availability are over.
