The main difference between IT and OT is their focus. IT is focused on information processing and communication, while OT is focused on physical process control and monitoring. IT is typically concerned with data at rest, while OT is concerned with data in motion. This means that IT is primarily concerned with the accuracy, confidentiality, and availability of data, while OT is primarily concerned with the reliability, safety, and performance of physical systems.

Another key difference between IT and OT is their underlying technology. IT is typically based on general-purpose hardware and software, such as servers, PCs, and enterprise software applications. OT, on the other hand, is typically based on specialized hardware and software, such as sensors, controllers, and custom software applications. This makes OT more complex and specialized than IT, requiring specialized skills and knowledge. Read more.
