Building OT Cybersecurity That Works in the Real World

Industrial environments are complex. Aging systems, distributed plants, and a crowded vendor landscape make “buy another tool” a tempting but often costly reflex.

In this episode, Dino Busalachi talks with Danielle “DJ” Jablanski, about moving from paper programs to measurable progress in OT security. They address why competence and capacity must come before capabilities, how to right-size your technology stack through tool rationalization, and why interdependence mapping is foundational for real resilience.

• 00:00:00 – Why OT maturity often stalls
• 00:06:00 – Where to focus first: assets, segmentation, and access
• 00:08:20 – Governance gaps: frameworks on paper vs. controls in practice
• 00:10:10 – Interdependence mapping beyond "crown jewels"
• 00:12:30 – Operators as first responders and safe-state realities
• 00:16:15 – Vendor and OEM ecosystems: who owns the response plan?
• 00:20:10 – Threat intel's limits: effects‑based security over means‑based noise
• 00:22:00 – Incident readiness in plants: plans, practice, and ownership
• 00:26:00 – Supply chain fragility and concentration risk in manufacturing
• 00:29:30 – Tool rationalization: measuring ROI, coverage, and usability
