In many companies, traditional IT systems are merging with operational technology (OT). This IT/OT convergence brings great efficiency gains – but also new risks. Outdated control systems meet modern cloud solutions, separate responsibilities become blurred and the attack surface for cyber threats grows. If you want to shape this change securely, you need a well thought-out architecture strategy.
1. Why IT/OT convergence is not just a technology issue
IT and OT traditionally have different goals: While IT systems are designed for availability, scalability and data protection, the focus in OT is on stability, real-time capability and physical security. In practice, this means that successful integration requires more than just interfaces – it needs a common understanding, coordinated processes and a clean role and authorization concept.
2. Recognize risks – and assess them systematically
Many companies underestimate the risks of poor system integration: if, for example, an old PLC suddenly has access to the company network or machines can be reached via unprotected remote access, serious security gaps can quickly arise. A structured quick check helps to identify weak points and develop a robust target image.
3. Architectural work is transformation work
Developing secure system architectures is not a one-off exercise. It must be coordinated with the organizational structure, the IT strategy and the regulatory framework. Companies benefit from interdisciplinary teams that understand technical dependencies as well as regulatory requirements – and can translate both into practicable architecture concepts.
4. Use standards – but pragmatically
Standards such as IEC 62443, ISO 27001 or TS 50701 provide valuable points of reference for securing IT/OT environments. However, no standard knows the individual structure of a company. Architecture consulting therefore also means putting these standards into a practicable context – without losing sight of the essentials.
5. From target image to implementation
A good architecture concept does not end in PowerPoint – but in concrete integration measures, IT roadmaps and accompanying transformation projects. This requires technical depth, but also methodological clarity and change expertise. Companies that actively steer this path create long-term security, transparency and future viability.
Conclusion
IT/OT convergence is a profound change – and at the same time a great opportunity. A strategic architectural approach can break down technical silos, minimize security risks and create modern IT landscapes that are built on a stable foundation.
