Compliance Isn’t Security: NERC CIP 15 and the Real Gaps in OT Network Monitoring

Passing an audit doesn’t mean you’re secure.

In this episode of Protect It All, host Aaron Crow dives into one of the biggest misconceptions in operational technology: the belief that compliance equals protection. Using NERC CIP 15 as a real-world case study, Aaron explores why meeting regulatory requirements is only the starting point - not the finish line.

A major focus of this conversation is OT network monitoring, especially the often-overlooked east-west traffic inside your environment. Many organizations monitor perimeter traffic while internal blind spots remain wide open.

You’ll learn:

Why compliance frameworks don’t automatically create security
The real challenges of implementing NERC CIP 15 at scale
Why internal network visibility (east-west monitoring) matters
How to establish meaningful baselines in legacy OT environments
The difference between audit success and operational resilience
Why architecture, tooling, and skilled personnel must work together

Whether you’re working in utilities, manufacturing, or critical infrastructure, this episode provides practical guidance on how to move beyond checklists and build security programs that truly reduce risk.

Tune in to learn how to transform compliance requirements into real operational protection - only on Protect It All.
