Asset Visibility Maps Relationships and Communication Pathways in OT Environments

This blog post argues that OT/ICS asset visibility is foundational to industrial cybersecurity: accurate inventories and visualized relationships between devices expose hidden communication paths, validate network segmentation, and reveal vendor or third‑party access risks that can enable lateral movement. The post highlights widespread weaknesses in segmentation and low adoption of asset discovery, and frames asset visibility (supported by automated collection) as a key enabler for improved monitoring, change-control enforcement, and more effective OT threat detection; it is part of a series with a forthcoming piece on threat detection efficacy.
