Case Study: ACH Group achieves reduced cyber risk and nearly zero overhead with Illumio

How Illumio Lowers ACH Group’s Cyber Risk — With Nearly Zero Overhead

ACH Group is a South Australian not‑for‑profit aged‑care provider serving about 20,000 older people with 1,800 staff. Facing the risk of ransomware and service disruption, limited budget and a small operations team, ACH needed an efficient way to segment workloads and enforce firewall policies across a hyper‑converged environment and legacy applications.

By deploying Illumio Core for a pragmatic Zero Trust segmentation strategy, ACH can tag workloads to automatically apply microsegmentation policies, map application dependencies, and create deny lists to block nonessential traffic. The result is revolutionary visibility into communications, the ability to separate dev/test/production on the same chassis, and almost zero management overhead (about two hours a week), significantly lowering ACH’s cyber risk.
