Case Study: St. Luke’s University Health Network achieves healthcare microsegmentation, robotic surgery enablement, and ransomware containment with Elisity

St. Luke’s University Health Network cuts hospital onboarding from 6–9 months to weeks with Elisity

St. Luke’s University Health Network, a major health system with 15 hospitals, faced a significant security and operational challenge. For a decade, their security team was unable to safely enable clinical innovations like surgical robots or quickly onboard acquired hospitals due to the limitations of traditional network segmentation tools like VLANs. This led to a reputation as the "Army of No." They partnered with vendor Elisity to implement its identity-based microsegmentation solution to overcome these hurdles without a network overhaul.

Elisity's agentless solution enabled St. Luke’s to discover, classify, and enforce policy based on device identity rather than IP address, using their existing network infrastructure. The results were transformative: surgical robots were securely enabled after a two-year wait, hospital acquisition onboarding was reduced from months to weeks, and the potential ransomware blast radius was contained to a handful of devices instead of an entire hospital. By implementing Elisity, the security team became a business enabler, reframing microsegmentation as a patient-care project.
