Protecting healthcare infrastructure at scale presents unique challenges that most security teams face but few solve effectively. Emplify Health manages over 100,000 devices across their network—many of them unmanaged, vendor-controlled, or completely invisible to traditional security tools. This fragmented device landscape created significant blind spots that put patient safety and data security at risk. The organization needed a solution that could provide complete device visibility across their entire connected ecosystem, including medical devices, IoT equipment, and legacy systems that conventional inventory tools couldn't detect or classify.
Device visibility became the foundation for Emplify Health's security transformation. By implementing comprehensive device discovery and classification, the team could see exactly what was connected to their network, understand the risk profile of each device, and identify which systems required immediate protection. This visibility extended beyond IT-managed assets to include clinical devices, vendor-managed equipment, and unmanaged IoT systems that are common in healthcare environments. With a complete inventory in place, security leaders could finally answer critical questions about their attack surface and make informed decisions about network architecture.
With complete device visibility established, Emplify Health designed and implemented a robust network segmentation strategy that isolates critical medical devices from general IT infrastructure. Network segmentation reduces the lateral movement capabilities of attackers and limits the blast radius of potential breaches by creating logical boundaries between different device types and risk levels. By mapping device dependencies and communication patterns, the team segmented their network into distinct zones for clinical devices, administrative systems, vendor equipment, and guest networks. This layered approach ensured that compromised devices in lower-security zones couldn't easily reach critical healthcare infrastructure.
The implementation of device visibility and network segmentation directly improved Emplify Health's incident response capabilities. When security events occur, responders can now quickly identify affected devices, understand what systems they can access, and determine the scope of potential compromise. The segmented network architecture also contains incidents more effectively, preventing attackers from moving freely throughout the infrastructure. Response times decreased significantly because teams had accurate data about device locations, configurations, and network relationships rather than relying on incomplete or outdated inventory information.
Emplify Health's experience demonstrates that device visibility is not a luxury in healthcare security—it's a prerequisite for effective risk management. Organizations managing large numbers of connected devices, particularly those including medical equipment and vendor-managed systems, cannot implement meaningful security controls without first understanding what exists on their network. Device visibility enables network segmentation, supports compliance with healthcare regulations like HIPAA, and provides the foundational data necessary for threat detection and incident response. Healthcare organizations facing similar challenges find that prioritizing comprehensive device discovery delivers immediate security improvements and long-term operational benefits.
