Case Study: Fortune 100 Bank achieves audit compliance and environmental separation with Illumio

Fortune 100 Bank Averts Audit Crisis Through Environmental Separation with Illumio

A Fortune 100 global trading bank with nearly 17,000 non-production workloads failed an audit for inadequate separation of development and production environments, risking fines and the ability to trade on the Nikkei. Network-based remediations would have required costly re-architecting, infrastructure upgrades, re-IPing and business downtime; VLANs and SDN proved ineffective and a homegrown approach couldn’t scale, leaving the bank under a tight compliance deadline.

The bank deployed Illumio’s Adaptive Security Platform to implement host-based segmentation that follows workloads without network changes, separating dev from prod and automating reporting and controls. The solution met the compliance deadline, avoided network rework, reduced operational overhead to less than one FTE overseas, improved visibility with Illumination and CMDB accuracy, and delivered a sustainable, auditable security model.
