The increasing connectivity of industrial systems is fundamentally changing security requirements. Production facilities, control systems, and industrial networks are now more interconnected with IT systems than ever before – and therefore more exposed to attacks. At the same time, OT environments differ significantly from traditional IT systems: availability, production safety, and physical processes are the primary focus. Standard IT security approaches are often insufficient in this context.
SYNSPACE Switzerland supports companies in protecting their OT and ICS environments in a structured manner – from risk analysis and security architectures to the implementation of security concepts based on the IEC 62443 standard.

In Short: What is IEC 62443?
The IEC 62443 is the leading global series of standards for the security of Industrial Automation and Control Systems (IACS). It was specifically developed for industrial control and production environments and defines requirements as well as best practices for protecting OT and ICS systems. In contrast to traditional IT security standards, IEC 62443 takes into account the specific requirements of industrial environments – in particular high availability, long lifecycles, and safety-critical processes.
-
Core elements of IEC 62443:
-
The standard provides companies with a structured framework to systematically assess OT security risks and build resilient industrial security architectures.
