Case Study: Leading eCommerce Retailing Company achieves PCI compliance in record time with Illumio ASP

Leading eCommerce Retailer Achieves PCI Compliance in Record Time with Illumio

A leading eCommerce retailer needed to ringfence its payment infrastructure to meet PCI DSS after penetration testing revealed vulnerabilities in a flat network that could allow lateral movement into its cardholder data environment (CDE). They faced urgent pressure to segment CDE systems and Tier 2 services that interface with payment processing or risk critical findings during their PCI audit.

The retailer deployed Illumio’s Adaptive Security Platform, using Illumination to map real-time application dependencies, Policy Generator and prepackaged segmentation templates to automate micro-segmentation and enforce user and environmental isolation. The rollout was completed within a month, delivering rapid PCI compliance for mission‑critical systems, simplified policy creation and full auditability, with plans to extend protection to another 1,000 workloads.
