What is OT (Operational Technology)?

Operational Technology (OT) is used to monitor and control physical processes and systems. Examples include production lines, industrial machinery, energy systems, and critical infrastructure such as water and transportation systems.

While IT focuses on data and information, OT directly impacts the physical world.

What Is Included in OT?

Typical OT environments include:

• Industrial Control Systems (ICS)
• SCADA systems
• Programmable Logic Controllers (PLCs)
• Sensors and actuators
• Industrial networks

These systems are commonly found in manufacturing, energy, oil and gas, transportation, and utilities.

OT vs IT: What’s the Difference?

Although OT and IT environments are increasingly interconnected, their priorities differ:

• IT focuses on confidentiality and data processing
• OT focuses on availability, safety, and continuity

In OT environments, disruptions can have immediate physical consequences.

Why Is OT Security Important?

OT systems were not originally designed with cybersecurity in mind. As digitalization and IT connectivity increase, they have become more exposed to cyber threats.

A successful attack on OT can result in:

• Production downtime
• Physical damage
• Safety incidents
• Societal disruption

OT and Cybersecurity

Effective OT security requires a different approach than traditional IT security, combining cybersecurity expertise with deep knowledge of industrial processes and systems.
