Operational Technology (OT)
What is Operational Technology (OT)?
Operational Technology, or OT, is the hardware and software used to monitor, control, and automate physical devices, industrial processes, and critical operations in the real world.
Examples
- A water treatment plant uses OT systems to control pumps, valves, and chemical dosing processes.
- A manufacturing facility uses OT to run conveyor belts, robotic arms, and production line sensors.

Most people interact with information technology every day through laptops, phones, email, websites, and cloud apps. Operational technology is different. It is concerned with physical outcomes. It helps start motors, open valves, stop turbines, move machinery, regulate temperature, and control industrial processes that affect the real world.
That difference makes OT especially important in cybersecurity. If a business application fails, people may lose data access or productivity. If an OT system fails, the consequences may include damaged equipment, interrupted utilities, safety incidents, production downtime, or harm to the public. This is why OT security is not just another version of office IT security. The environment, priorities, and risks are often very different.
Summary 📝
Operational Technology is the set of systems used to monitor and control real-world physical processes. It differs from traditional IT because it is closely tied to safety, reliability, and operational continuity rather than only data handling and business applications. OT security matters deeply because cyber compromise in these environments can affect machinery, infrastructure, utilities, and human safety in the physical world.
