Case Study: Hi-Temp Insulation, Inc achieves 30-minute micro-segmentation and real-time traffic visibility with Illumio

Hi-Temp Insulation Launches Illumio’s Micro-Segmentation Security in Just 30 Minutes

Hi-Temp Insulation, a California-based aerospace and defense manufacturer, needed stronger, least-privilege security to meet new DoD-related requirements. The company lacked visibility into east‑west traffic, relied on labor‑intensive Windows Group Policy Objects (GPOs), and found tracing issues in text logs and pushing changes took hours—so “good enough” was no longer acceptable.

Hi-Temp deployed Illumio Core and in under 30 minutes gained a real‑time application dependency map and historical traffic visibility. The platform let them reduce hundreds of GPO rules to 19 policies, shift enforcement to the server level, and cut troubleshooting and policy deployment from hours to minutes—resulting in tighter, more granular protection, faster incident response, and greater confidence in their security posture.
