Industrial DMZ Definition: An Industrial DMZ or IDMZ is a buffer network segment isolating IT from OT systems to broker and inspect traffic per the Purdue Model.
An Industrial DMZ, also called an IDMZ or OT DMZ, is a segmented network buffer zone placed between an enterprise IT network and an operational technology or industrial control system network to broker and inspect all traffic crossing between the two. Aligned with the Purdue Reference Model, it prevents direct connectivity between business systems and plant-floor devices, hosting intermediary services like jump servers, patch repositories, and data historians. This separation limits the spread of threats from corporate networks into safety-critical OT environments.
