Practical Offensive Industrial Security Essentials

Break into OT Security with Realistic Offensive Simulations

Master Engineering‑Driven Industrial Cybersecurity. Gain real-world offensive OT cybersecurity experience—without expensive hardware or hype.

Hi, I'm Marcel

Most industrial security courses are built by people who learned about OT. This one is built by someone who lived it. I’m not a computer scientist who pivoted into OT security—I’m a trained automation engineer with over two decades in the field. I’ve commissioned production lines, troubleshot PLCs on the factory floor, integrated HMIs, and designed systems from the inside out. This course is built on everything I’ve learned—and everything I wish I’d had when I started.

What is Engineering‑Driven Industrial Cybersecurity?

Learn not from an IT‑centric crash course, but from someone who’s designed, deployed, and protected industrial systems in the field. You’ll get a true perspective—spotting real device risks and building your own protection strategies, free of marketing noise.

If you're serious about learning how industrial systems really work—and how to protect them with clarity, not guesswork—this is the course you’ve been looking for.

✅ Learn from a Pro: Course built by a veteran automation engineer — academic theory and real‑world OT know‑how.

✅ Cut Through the Hype: Hands‑on labs expose genuine vulnerabilities so you can distinguish real threats from OT‑security marketing bullshit.

✅ Holistic ICS Security: Deep dive into tools, device internals, and network architecture.

✅ Hands‑On Practice: Multiple simulated industrial environments.

✅ Portfolio Builder: 8 real‑world labs you can showcase on LinkedIn or in your CV.

✅ Community & Support: Join our course community channel

Built for Curious Learners. No Gatekeeping. No BS.

This course was created for people who are ready to dive in and think for themselves—no matter their background. Whether you’re an IT pro, OT engineer, student, or career-switcher, if you’re motivated to learn, this is your starting point. “I don’t care where you’re from—your curiosity matters, your background doesn’t.”

👨‍💻 For IT Professionals:

Step into the world of OT security with confidence. This course bridges your IT know-how with hands-on exposure to real industrial systems.

Learn how attacks work on PLCs, field devices, and protocols like Modbus and S7—so you can better protect, assess, or even red-team industrial environments.

No guesswork—just structured, practical learning built for IT pros entering OT.

🤖 For Automation Professionals and Engineers:

Your machines are safe. But are they secure?

This course shows how attackers view industrial environments—from scanning networks to exploiting PLCs and HMIs.

With real simulations of Siemens, Rockwell, and more, you'll gain powerful insight into threats and how to prevent them.

No fluff—just actionable knowledge to help protect the systems you know best.

🌱 For Complete Newcomers:

 Curious about how hackers break into industrial systems? This course is your perfect starting point.  
No prior experience required—just curiosity! You'll explore real-world ICS environments, learn to use hacking tools step by step, and understand how industrial networks and devices are attacked (and protected).  

It’s hands-on, beginner-friendly, and built to help you grow fast—whether you're aiming for cybersecurity, OT, or a new tech career.

Does This Sound Like You?

This course is for you if…

✅ You want real OT cybersecurity experience, not just buzzwords

✅ You want to understand how OT systems are exposed, how attackers think, and how to mitigate real-world risk
 
✅ You’re tired of $2,000+ courses with locked ecosystems
 
✅ You learn best by doing, not watching slides.
 
✅ You’re ready to take ownership of your education


This course is not for you if…

❌ You expect hand-holding every step of the way

❌ You expect traditional IT-style hacking focused on full system takeover, RCEs, or buffer overflow chains

❌ You’re not comfortable doing a bit of setup and troubleshooting

❌ You want to “watch and forget”—this course requires doing

❌ You don't want to think independently and research like an engineer

Get your hacker hoodie and black hat ready - we are going to look at industrial control systems and networks
from an adversary perspective!

By the end of this course, you’ll:

✅ Understand the real OT attack surface—protocols, devices, vulnerabilities.
 
✅ Learn how attackers think, work, and gain access in industrial systems.
 
✅ Gain hands-on experience with 8 unique labs of industrial environments.
 
✅ See how OT systems are often insecure by design—and what you can realistically do to improve security.

✅ Build your own lab from open-source tools you can keep using—even after the course ends.
 
✅ Get a certificate of completion and join an active OT security community.

Built on Proven Foundations—Now Stronger Than Ever

Battle-Tested. Rebuilt. Supercharged.

Practical Offensive Industrial Security Essentials is built on the success of my previous course, Practical Industrial Control Systems Penetration Testing (PICSPT), which launched in 2023 and received overwhelmingly positive feedback from students around the world.  

But I didn’t stop there. I took everything I learned from thousands of learners—the praise, the criticism, and the real-world use cases—and rebuilt this course from the ground up.

By joining this course, you're not just stepping into a brand-new learning experience— you're entering a proven training ground, now rebuilt to be even more powerful, practical, and aligned with your needs.


Welcome to the upgrade:

🔧 Reengineered from community feedback

📈 Expanded with more hands-on labs, more tooling, and more OT realism

🧠 Designed to meet the real questions, struggles, and needs of learners in the field


 “The course equipped me to learn about testing real life [although simulated] ICS devices. The final Red team assignment was icing on the cake, reminded me of Matrix 2 movie scene of shutting down Power Plant”  

Khanjen P. ⭐⭐⭐⭐⭐
PICSPT Alumni

"Course is well laid out, detailed with practical examples and exercises, bridging the gap between theory and practical. I would highly recommend this course." 

Rohan V. ⭐⭐⭐⭐
PICSPT Alumni

"Training was put together well and identified all of the necessary tools. Hits close to home as one of the devices shown was only a few miles away from where I live. Hopefully they have fixed that since the data was collected eight years ago." 

Michael E. ⭐⭐⭐⭐
PICSPT Alumni
