Case Study: AmLaw 10 Firm achieves audit-ready, infrastructure-agnostic micro-segmentation with Illumio

AmLaw 10 Firm Aces Client Security Audits With Illumio

An AmLaw 10 law firm with a 2,000-server data center supporting 100+ mission‑critical applications faced recurring security audits and PEN testing that required strict isolation of sensitive client data. Traditional firewalls, SDN and hypervisor solutions proved too complex, incompatible, or costly—especially with a pending cloud migration—so the firm needed an infrastructure‑agnostic way to achieve consistent, audit‑ready segmentation across heterogeneous environments.

The firm deployed Illumio Core, standing up the Policy Compute Engine in 45 minutes to begin creating policies and using Illumio’s real‑time application visibility to work with app owners on enforcement. The result was uniform, zero‑trust micro‑segmentation (including cloud workloads), simplified policy management via human‑readable labels, streamlined audit reporting, and a roadmap for deeper “honeycombing” and nano‑segmentation.
