// The Basics

What is OT (Operational Technology)?

Operational Technology (OT) refers to hardware and software that manages and monitors physical processes, such as machines, sensors, and systems in sectors like energy, water management, and oil & gas. With increasing digitalization, OT is becoming increasingly vulnerable to cyber threats. Technologies like the MagiCtwin protect OT through secure one-way data communication and network segmentation.

What is a data diode and why is it important?

A data diode is a hardware-based solution that physically allows data flows to flow in one direction. This prevents cyber threats from reaching critical OT systems. The MagiCtwin provides reliable one-way communication and complies with strict standards such as NIS2.

Why is physical separation crucial in OT/IT security?

Physical separation, such as an air-gapped network, prevents threats from OT processes from affecting IT networks. The MagiCtwin ensures controlled, one-way traffic, keeping critical operational systems isolated and protected from cyberattacks and sabotage. As a product evaluated by the AIVD BSPA, it offers a proven, secure solution for network isolation.

What are push and pull methods in data exchange?

The push method sends data directly from a sender to a receiver, while the pull method actively retrieves the data from the receiver. The MagiCtwin supports both methods, whether based on scheduled file sharing (e.g., periodically) or in real time for protocols like OPC-UA or via port mirroring. This enables flexible, secure, and controlled data exchange.

How does the MagiCtwin support secure OT/IT separation?

The MagiCtwin provides one-way physical communication, allowing data flows from OT to IT without the risk of external access or feedback. This prevents cyberattacks and protects operational continuity.
