Case Study: Kingston Technology achieves rapid OT risk reduction and minute-scale segmentation with Zscaler Zero Trust Device Segmentation

Kingston Technology Reduces Risk Through Segmentation of Mission-Critical OT Devices

Kingston Technology, a global leader in memory products (3,000+ employees, 63+ SMT lines), faced a complex legacy segmentation environment on its factory floor that spanned 90 device types—thermal units, packaging and testing machines, and production-line equipment. Misprovisioned access and slow, disruptive policy changes (often requiring days of device downtime) increased OT risk and made policy management onerous.

Kingston deployed Zscaler Zero Trust Exchange (Zscaler Internet Access and Private Access) and Zero Trust Device Segmentation to extend zero trust to the factory floor with zero endpoint agents and no need for east–west firewalls or VLAN readdressing. The solution enforces granular, MAC-address-level policies on every endpoint, reduces complexity and risk, and applies segmentation in minutes—securing 90 device types with zero downtime.
