Operational technology (OT) environments are increasingly implementing visibility-driven network segmentation as a key cybersecurity strategy, according to industry experts and recent studies. At the S4x26 conference held in February 2026 in Miami, security professionals demonstrated that integrating asset discovery and segmentation policy enforcement directly into network infrastructure-rather than applying them as overlays-significantly reduced the effort and risk involved in securing OT environments, according to Cisco. This method revealed previously undetected device communications and enabled real-time, protocol-aware zone definition and enforcement.
