Practical, hands-on training built from 18 years of field experience securing industrial control systems. From Purdue and SCADA fundamentals to IEC 62443 and zero trust — without the academic jargon.
A progressive path that takes you from “what is a PLC?” to running a credible IEC 62443 risk assessment on a real plant.
DCS, SCADA, PLCs, RTUs, the Purdue model, IT vs OT, safety instrumented systems — the vocabulary you need before anything else.
Modbus, IEC 61850 (MMS / GOOSE / SMV), BACnet, MQTT, IIoT — what they look like on the wire and how attackers abuse them.
Security levels, foundational requirements, zones & conduits, defense in depth, risk calculation — the real frameworks regulators expect.
OT-aware NIDS, NGFW/IPS placement, endpoint protection, IAM & NAC, secure remote access, zero trust for plant networks.
Substations and IEC 61850, oil & gas pipelines and Modbus, building management with BACnet — protocols in their native habitat.
Risk assessment workflow, asset visibility, capability maturity, pentest tradeoffs — the conversations you have with plant owners.
Chapter 1, Lesson 1: Mission Industrial Revolution. A 3-minute look at why operational technology cybersecurity is a discipline of its own — and why most IT-trained engineers get it wrong on day one.
If the teaching style works for you, the rest of the course will too.

The book the course is built on. Real-world application instead of dense academic theory — actionable, bite-sized, and proven in classrooms from Riyadh to Dubai to Amman.
Not a re-skilled IT professional discovering OT in their late thirties.
Eighteen years securing operational technology — IT, IoT, IoMT, and OT. Senior engineer and subject-matter expert, working with the major OT security vendors and delivering field engagements for industrial customers around the world.
Author of How to be OT Cybersecurity Professional (Austin Macauley, 2023). Created the OT Cybersecurity Fundamentals course on Udemy in 2021 — 5,000+ students and growing. Certified instructor in vendor-specific OT security programs.
The training and writing here distills that field experience into something you can apply without needing me on speed-dial.
Most digital twins draw from ICS/SCADA and ignore the goldmine sitting in security monitoring tools. NeuroTwin is an ongoing project that feeds IDS-grade protocol analysis into ML models, producing twins that are predictive and adaptive — not just reflective.
