Cyber attacks are increasingly targeting the critical environments we rely on, from power plants to water treatment facilities. This course will teach you how to defend them!


Industrial Control Systems (ICS) and Operational Technology (OT) run the world around us. Power plants, offshore oil rigs, transportation systems, and manufacturing facilities are just a few examples of the infrastructure society depends on—each with unique operations and specialized security requirements.


As cyber attacks become more frequent and accessible, the threat landscape is expanding. Nation-state adversaries are no longer the only concern. Today’s attackers include ransomware groups, hacktivists, cyber mercenaries, and more.

ICS/OT cybersecurity can feel complex and even overwhelming at first... but it doesn’t have to be!


This course is designed to help you understand how these environments operate and how to secure them effectively. You’ll build a strong foundation in OT/ICS systems while gaining practical insight into protecting these critical networks.

OSINT (Open Source Intelligence) for OT/ICS

May 23, 2026

8:30 AM - 4:30 PM ET

Live (Virtual)

$25

Register >

This course helps you find your vulnerabilities before an attacker does!


Most ICS/OT cybersecurity (and non-cybersecurity) professionals aren’t familiar with how OSINT can be used to help secure OT environments from attack.
Or how just a few hours of OSINT can uncover significant vulnerabilities an attacker could exploit.


The course also introduces the first phase of both ICS/OT and IT penetration testing—reconnaissance—where OSINT is used to gather relevant information about a target organization.


And the more relevant data you have, the more successful you’ll be!


Course agenda:

  • Part 1: Course Introduction

  • Part 2: Getting Started with OSINT

  • Part 3: Social Media

  • Part 4: Email Addresses, Usernames, and Passwords

  • Part 5: Domain Names, IP Addresses, and ASNs

  • Part 6: Traditional Search Engines

  • Part 7: Specialized Search Engines for ICS/OT

  • Part 8: Writing a Successful OSINT Report

  • Part 9: Review Questions


What’s included:

  • Slides

  • Lab manual

  • Session recordings

  • Certificate of Completion (8 CPEs) (provided after completing a 10-question quiz)


Can’t attend live?
All course content, including recordings, will be available for download for 30 days after the course.

Intro to OT/ICS Penetration Testing

June 4 & 5, 2026

8:30 AM - 4:30 PM ET

Live (Virtual)

Very few resources exist for understanding how to perform penetration testing in OT/ICS environments.... but this course changes that!


There is a TON of knowledge and practical, hands-on labs packed into this one-day course.


You’ll explore key questions like:

  • How is OT/ICS penetration testing different from IT?

  • How do we conduct testing safely in critical environments?

  • How do we evaluate the cybersecurity of OT networks and assets like PLCs and HMIs?

This course is designed to help you identify real security gaps in your OT/ICS cybersecurity program.


Even more so, it helps you understand how to think like an attacker in OT/ICS environments such as power plants, chemical refineries, and water treatment facilities.


Hands-on labs are included to complete at your own pace, giving you a deeper, more practical understanding of breaking into OT/ICS networks.


Course agenda:

  • Part 1: Course Introduction

  • Part 2: Getting Started with OT/ICS Penetration Testing

  • Part 3: IT Penetration Testing Overview

  • Part 4: The OT/ICS Penetration Testing Framework

  • Part 5: Reconnaissance and OSINT

  • Part 6: Discovery and Enumerating OT Assets

  • Part 7: Attacking and Compromising OT Assets

  • Part 8: Impacting Operators and Industrial Processes

  • Part 9: Writing a Successful OT/ICS Penetration Testing Report

  • Part 10: Review Questions


What’s included:

  • Slides

  • Lab manual

  • Session recordings

  • Certificate of Completion (8 CPEs) (provided after passing a 20-question quiz)
