Case Study: Top Health Insurance Provider achieves enhanced cyber resilience and ransomware containment with Illumio

Top Health Insurance Provider Boosts Cyber Resilence With Illumio

A market-leading European health insurer serving over one million members needed to better protect high-value PHI and PII after routine security audits showed inadequate server-to-server controls and exposure to ransomware lateral movement. The IT security team prioritized a practical, operationally efficient way to minimize breach impact, speed recovery, and meet regulatory requirements without disruptive re‑architecture.

They chose Illumio Core for Zero Trust microsegmentation after a successful proof of concept, quickly segmenting tier‑one claims, financial and policy systems with no downtime. The solution delivered reusable policies, intuitive real‑time traffic visualizations, and immediate containment capabilities—significantly reducing the blast radius of potential attacks, improving audit readiness, and strengthening overall cyber resilience cost‑effectively.
