Free OT Cybersecurity Training for Beginners – Best Free Courses
Industrial automation systems are becoming smarter, faster, and more connected than ever before. Modern industries now rely heavily on PLCs, DCS systems, SCADA platforms, Industrial IoT devices, and cloud-based monitoring systems for efficient plant operations.
However, this increasing connectivity has also created new cybersecurity risks.
Today, industrial facilities such as oil & gas plants, power plants, chemical industries, water treatment plants, manufacturing industries, and pharmaceutical factories are facing serious cyber threats targeting Operational Technology (OT) environments.
Unlike traditional IT systems, OT systems directly control physical industrial processes. A successful cyberattack on an Industrial Control System (ICS) can lead to:
- Plant shutdowns
- Production loss
- Equipment damage
- Environmental hazards
- Safety incidents
Because of this, OT cybersecurity has become one of the fastest-growing fields in industrial automation.
The good news is that there are several high-quality free OT cybersecurity training videos available online for beginners, instrumentation engineers, automation professionals, and industrial cybersecurity learners.
In this article, we are exploring some of the best free OT cybersecurity training videos that explain industrial cybersecurity concepts in a practical and beginner-friendly way.
