Stopping ransomware before it reached clinical systems

A combined assessment found that a single compromised workstation could reach clinical systems across a flat network, and mapped the segmentation needed to stop it.

The challenge

After ransomware crippled a peer organization, the network needed to know whether the same attack could spread to systems that directly support patient care. Years of acquisitions had left the internal network largely flat and poorly understood.

Our approach

Performed an assumed-breach assessment starting from a single standard workstation
Mapped lateral movement paths from corporate IT toward clinical and device networks
Tested the resilience of backup and recovery systems to a ransomware-style attack
Delivered a prioritized segmentation plan tied to the specific paths we exploited

“We thought we understood our network. The assessment showed us we didn't, and gave us a plan we could actually execute.”

— Chief Information Security Officer, National Healthcare Network
