How GreyMatter Defends Healthcare Environments
The speed differential demands autonomous defense. When breakout time is measured in minutes, detection-to-containment must operate at machine speed.
Detection Coverage Independent of Device Manageability
In most healthcare environments, a large proportion of connected devices can't run an agent or ship a log—leaving entire network segments permanently dark to the SOC. Threat actors like Sinobi and Qilin know this and exploit clinical environments accordingly.
External Credential Surface Monitoring Across a Distributed Workforce
Nearly half of healthcare external monitoring alerts stem from credential exposure—the majority from third-party firms and contractors who have the same environmental access as internal clinicians. Initial access brokers advertise these credentials weeks before active exploitation campaigns begin.
Continuous Asset Discovery and Vulnerability Scoring
Healthcare M&A activity creates inherited network segments where no asset inventory exists—unpatched vendor appliances, building-management controllers, and legacy imaging systems operate without visibility.
Unified Investigation and Autonomous Response Across Clinical and Enterprise Systems
Device-code phishing campaigns steal M365 tokens that survive password resets—and investigating the blast radius requires pivoting across EHR logs, identity platforms, email gateways, and endpoint telemetry manually. Each pivot means a different query language, a different console, and manual context-stitching.
From telemetry event to validated detection via GreyMatter Transit.
