Case Study: Global Financial Services Firm achieves safer, simpler brownfield migration to a new data center with Illumio

Global Financial Services Firm Secures Brownfield Migration to New Data Center with Illumio

A leading global bank launched a $1B data center revitalization to re-platform and migrate 5,000 applications and 33,000 workloads from a brownfield environment. Aging operating systems and limited staff knowledge of application dependencies created systemic operational and cybersecurity risk, making a safe, non-disruptive migration a top priority.

The bank used Illumio’s Adaptive Security Platform to gain real-time application dependency visibility and apply micro-segmentation, enabling policy creation without relying on VLANs or IP constructs. The approach delivered safer, simpler, and more cost‑effective security, faster vulnerability remediation, and a more accurate CMDB to support ongoing IT performance and resilience.
