Case Study: Top Healthcare Education Institution achieves cloud-scale PII protection with Illumio ASP

Top Healthcare Education Institution Secures PII From Breach With Illumio

A top healthcare career school supporting 15,000 students and faculty faced a cloud-scale security challenge: protecting regulated PII with a constantly changing user population. Traditional perimeter and internal firewalls created operational bottlenecks, outage risk, and insufficient granularity for dynamic user-to-database segmentation, so the IT team needed a scalable, low-impact way to enforce compliance-grade controls.

They deployed Illumio’s Adaptive Segmentation Platform (ASP), using host-based enforcement via the Windows Filtering Platform and a real-time application dependency map to visualize traffic and test policies without outages. The result: same-day visibility, granular, dynamic segmentation across data centers and Azure, no network re-architecture or downtime, and stronger protection of PII and environment separation.
