In this episode of Exploited: The Cyber Truth, host Paul Ducklin is joined by Shane Fry, CTO of RunSafe Security, and Andrew McPhee, Solutions Manager for Industrial Security at Cisco, to examine why visibility is one of the biggest challenges in OT cybersecurity.

As industrial environments become more connected, organizations are struggling to identify unknown assets, understand hidden dependencies, and secure systems that were never designed with cybersecurity in mind. McPhee explains how attackers exploit these blind spots, why traditional IT security approaches often fall short in OT environments, and how visibility and segmentation can help reduce risk.

Together, they explore:

Why asset visibility is the foundation of OT security
How unknown assets and communication pathways create risk
The differences between active and passive asset discovery
Why segmentation remains one of the most effective OT security controls
How IT/OT convergence is expanding the attack surface
The role of risk tolerance and risk acceptance in security decisions

From manufacturing facilities to critical infrastructure, this episode explores what security teams must understand before they can effectively protect the systems they depend on.
