Operations technology
Operations technology (OT), also known as operational technology, is the backbone of modern industry, orchestrating, supervising, and optimising physical processes and machinery. This essential technology facilitates seamless data collection and interconnectivity among machines and systems, revolutionising efficiency, productivity, and safety across the entire production spectrum.

What is Operations Technology?
OT encompasses both hardware and software tailored for monitoring, managing, controlling, and fine-tuning physical processes, tools, and devices on factory floors. Its primary objective is to provide deep insights into daily operations, empowering informed decision-making through real-time data collection and analysis.
One of the cornerstone components of OT lies in Industrial Control Systems (ICS). These systems constitute a vital cog in ensuring smooth operations and peak performance within industrial settings.
Supervisory Control and Data Acquisition Systems (SCADA) stand as the linchpin for real-time monitoring and control of systems, particularly prevalent in sectors like energy, water supply, and manufacturing. By gathering data from sensors and devices, SCADA enables operators to swiftly respond to changes and make informed decisions.
Programmable Logic Controllers (PLC), on the other hand, are specialised computing devices engineered to automate and govern various tasks, processes, and machinery with precision. From regulating temperatures to orchestrating automated machine motions, PLCs ensure consistent and reliable production.
Human Machine Interface (HMI) technology facilitates seamless interaction between users and machines through intuitive interfaces like touchscreens. This empowers operators to monitor, control, and interact with systems efficiently, thereby augmenting productivity and safety.
Beyond mere process monitoring, the integration of technologies such as PLCs, SCADA, and HMI within OT enables companies to bolster productivity, efficiency, and precision while fortifying security and competitiveness.
Advantages of Operations Technology
Cost Effectiveness
Improved data collection and process control lead to optimised resource utilisation, extending the lifespan of machinery and reducing maintenance costs.
Efficiency and Reliability
OT enables real-time process monitoring, automates tasks, reduces manual intervention, and minimises errors. Data-driven insights pave the way for informed decision-making, optimising manufacturing processes and fostering competitive advantage.
What is the difference between OT, IT, IoT, and IIoT?
To leverage the benefits of digitisation and keep up with increasingly rapid innovation, it is important to understand the functions and differences between OT, IT, IoT, and IIoT.
Operations technology (OT), as previously mentioned, is the technology that manages monitoring, operation, and communication between physical processes and machinery.
Information technology (IT) refers to the computer technology, software, and networks that process digital information. IT constitutes a fundamental building block in most businesses when it comes to organising, storing, and analysing data.
Internet of Things (IoT) is the term used for the technology that connects physical objects to the internet. It can range from home alarms and smart bulbs to advanced medical devices and systems for smart cities. By enabling communication between devices, IoT provides real-time data and insights for informed decision-making, equipment monitoring, and optimisation of operations.
Industrial Internet of Things (IIoT) refers to smart, connected devices used in industry for process automation and machine self-regulation. The technology enables efficient troubleshooting, optimisation, and provides better foundations for decision-making in production, energy, and other industrial areas. IIoT is closely related to the concept of Industry 4.0, where digitisation and automation play a central role in transforming the industry.
In summary, IT handles digital information, while OT controls physical processes. IoT connects physical objects to the internet to create a smarter world, with IIoT being an application of the same technology in industrial environments to enhance efficiency, security, and competitiveness within the industry.
What is the difference between OT security and IT security?
Traditionally, OT security is about maintaining high operational reliability and functionality for physical machines within an OT network on the factory floor. This includes preventing physical damage, disruptions in production, and operational downtime. IT security is a broad term that includes cybersecurity, privacy protection, and information security to protect digital information and data.
At the same time, we see that OT devices are increasingly being connected to IT networks, clouds, and servers. This integration has led to increased availability and more efficient automated systems. But it also means new attack surfaces and greater exposure to hackers and cyber threats.
The concepts simply blend into each other. This means that cybersecurity must be integrated throughout the infrastructure – from IT to OT. Common to both OT and IT security is the need for a thorough risk analysis. By understanding the risks as a whole, you can combine security measures based on both digital technology, information security, mechanical protection, and secure work practices.
