    Abstract

    Organizations are operating in mixed environments where cloud workloads, plant-floor assets, and edge devices share connectivity—but not the same security assumptions. This paper outlines a layered approach that starts with identity, enforces device integrity, applies microsegmentation, and continuously evaluates trust signals with AI-powered detection. The goal is to reduce blast radius, eliminate credential dependency, and support compliance-ready auditability.
