OT and IT have developed differently over time. While IT focuses on data, applications, and business processes, OT controls machines, systems, and physical processes. In OT, the focus is on human and system safety and maximum stability, while in IT, the focus is more on agility, scalability, and efficiency. It is crucial for CIOs to understand and respect these differences instead of trying to “equalize” them technically.

OT systems are often based on proprietary technologies, long life cycles, and isolated networks. IT systems, on the other hand, are highly standardized, networked, and subject to rapid innovation cycles. When both worlds are brought together, it is not only different technologies that collide, but also different operating models and responsibilities. Clear responsibilities and clean interfaces are therefore essential.

With increasing connectivity, the attack surface is growing. Cybersecurity is one of the most sensitive issues at the interface between OT and IT. A security incident in production can have far-reaching consequences, from downtime to physical damage. At the same time, availability must be guaranteed at all times. CIOs must establish security concepts that take both worlds into account without jeopardizing operations.

The convergence of OT and IT is not purely a technology project, but rather a long-term transformation process. Successful companies promote exchange between teams, establish common standards, and pursue a clear target architecture. For CIOs, this means being bridge builders: enabling innovation, creating transparency, and at the same time ensuring production stability.

OT vs. IT is not a conflict, but an opportunity. Those who take a holistic view of the four core areas lay the foundation for efficient, secure, and future-proof industrial IT landscapes.
