Case Study: Fast-Growing SaaS Company achieves $10M+ savings and secures two new data centers with Illumio

Fast-Growing SaaS Company Protects Two New Data Centers with Illumio

A large, fast‑growing SaaS provider needed to stand up two new data centers in two countries to support customer and geographic growth while protecting sensitive customer data and meeting regional compliance — securing about 9,000 workloads on a tight, sub‑six‑month schedule. The team wanted to avoid costly, complex network segmentation based on fine‑grained VLANs and high‑capacity firewalls in every rack, and to preserve an agile application development culture despite rising east/west data center traffic.

They deployed the Illumio Adaptive Security Platform to provide adaptive segmentation across bare‑metal, virtual, on‑premises and cloud workloads, enabling fine‑grained application and environment separation. The rollout reduced segmentation complexity from roughly 15,000 firewall rules to 40 Illumio policies, eliminated the need for per‑rack high‑capacity firewalls, flattened the network, saved over $10M in hardware costs, and improved visibility, compliance alignment, and deployment speed.
