Case Study: World’s Largest Multinational Bank achieves automated, scalable container segmentation and faster app launches with Illumio

Global 50 Bank Undergoing Digital Transformation Secures Containers with Illumio

A Global 50 multinational bank undertaking a digital transformation needed to speed delivery of new and re-platformed applications while eliminating legacy security debt. Networking and SDN solutions failed to provide automated, consistent segmentation across heterogeneous environments (containers and public cloud), blocking the bank’s automated self-service developer portal and undermining the security rationale for a new data center.

The bank implemented Illumio’s Adaptive Security Platform, decoupling micro‑segmentation from the network and integrating policy and enforcement into its automation and self‑service portal via APIs. In roughly 14–18 months the solution ringfenced applications at scale—growing from zero to ~16,000 servers and over 15,000 segmented workloads, with 1,000 hosts running tens of thousands of containers—enabling developers to spin up workloads in minutes and restoring security, speed, and business competitiveness.
