Case Study: West Bend Mutual Insurance achieves secure, consistent cloud segmentation and improved stability with Illumio Core

West Bend Mutual Insurance Has Segmentation in the Cloud Covered with Illumio

West Bend Mutual Insurance, a 125‑year‑old Midwest insurer, needed stronger internal controls to limit breach and ransomware impact, so it pursued micro‑segmentation. Their initial hypervisor‑driven solution broke network interfaces and caused production outages during an Azure migration, and Azure’s native controls couldn’t enforce centralized policies across multiple subscriptions and VNets. Visibility was also costly and disconnected from policy workflows, blocking workload moves until security parity with on‑premises could be guaranteed.

WBMI selected Illumio Core—a SaaS, non‑intrusive segmentation platform with unified visibility and simple label‑based policies. After using Illumio’s map in visibility mode, the team completed a 10‑minute cutover with no downtime, centralized policy across cloud and data centers, and simplified audits. The deployment improved stability and reliability and reduced troubleshooting time by about 30%, enabling secure, faster cloud migrations.
