NAT-Gateway / Microsegmentation in OT networks

Industrial Network Security by MB connect line provides advanced protection for production and machine networks, specifically designed for the requirements of industrial OT environments. The solution enables operators and machine builders to secure, control, and monitor access to machines and production networks, while preserving established OT workflows and minimizing operational complexity.

The system acts as a compact, industrial-grade security gateway and firewall, protecting machines, cells, and production lines against unauthorized access. It allows secure integration of new machines into existing networks without address conflicts and enables secure access to machine components both locally and remotely. Legacy devices and older installations can be protected without requiring changes to the existing network infrastructure.

Network functions such as NAT, port control, and selective visibility of machine components help reduce attack surfaces and ensure that only explicitly required connections are exposed.

To further strengthen security, the solution supports network micro-segmentation, allowing machine components and sensitive or obsolete devices to be isolated into separate, protected zones. This prevents lateral movement within the OT network and increases resilience against industrial cyber threats.

MB connect line follows a strict Security-by-Design approach. IT security principles are embedded into all stages of product development and operation, including regular security audits, penetration tests, continuous vulnerability monitoring, and structured update processes. The company actively contributes to industrial security working groups and aligns its product evaluations with IEC 62443‑4‑2 requirements, reinforcing its commitment to industrial cybersecurity best practices.

Overall, Industrial Network Security by MB connect line offers a robust, OT‑focused security solution that combines strong network protection, flexible access control, and seamless IT/OT integration—enabling secure production environments without compromising operational efficiency.
