Whitepaper: Secure OT/IT Integration for Critical Infrastructures

Intellectual property (IP) is invaluable to high-tech companies but is increasingly targeted by cybercriminals and state actors. A recent attack on a leading technology company showed how attackers exfiltrated sensitive designs and production methods through a vulnerable network connection. This resulted in significant economic damage and risks to the company’s strategic position.

The MagiCtwin product family prevents this risk through physical separation using data diodes and strictly regulated two-way communication. This blocks lateral attacker movement and prevents unwanted exfiltration of sensitive data. By integrating MagiCtwin solutions within a zero-trust strategy, critical infrastructures remain protected, and operational processes are safeguarded.

The MagiCtwin product family offers a robust solution for OT/IT integration through two NextGen firewalls and hardware separation via diode technology. This allows organizations to exchange data securely without the risk of IT threats infiltrating OT systems.

The MagiCtwin Diode ensures a one-way connection, sending data from OT to IT with no possible feedback. This prevents cyberattacks or malware from reaching the OT network via IT. For situations where two-way traffic is necessary, the MagiCtwin Firewall² provides controlled communication via strict protocol regulation.

Both variants are based on CompuWall technology and certified by the Dutch government for use in confidential environments. Through a central web-based management system, organizations can easily manage and secure their data flows.

The differences between OT and IT make secure integration complex. IT systems are frequently updated and have a short lifecycle, while OT installations often operate for decades without significant changes. Many OT systems are not designed with cybersecurity in mind, making them particularly vulnerable.

Additionally, regulations such as the NIS2 directive impose strict requirements on the security of critical infrastructures. Organizations must demonstrate that their networks and processes are protected against cyber threats. This requires not only technical measures but also clear policies and network segmentation.
