Cybersecurity out of the box

Industrial DMZ Infrastructure

Industrial DMZ Infrastructure is a ready-to-run concept for IT/OT network segmentation with integrated security features - implemented on a hyper-convergent IT platform. Thanks to the combined know-how of Siemens experts in the fields of automation, digitalization and cybersecurity, the solution is optimized for use in production and meets the highest requirements in terms of availability and security. Our holistic approach includes consulting, configuration, and appropriate support services over the entire life cycle. 

Cybersecurity is essential! But where to start?

Powerful networks are a core element of digitalization. But they also increase the risk of cyberattacks. Security standards and regulations, vulnerabilities and malware – a lot of things have to be considered, which can be overwhelming. Our Industrial Security experts make sure that you can focus on your core business – with Industrial DMZ Infrastructure, contributing to the Defense in Depth concept.

Preventing unauthorized access according to IEC 62443

Due to a DMZ (demilitarized zone) with front and back firewalls, the OT systems are shielded from the corporate IT. This network segmentation allows access to systems that require data from the Internet and at the same time protects the system network from unauthorized access from outside. This corresponds to the recommendation of IEC 62443, the leading international standard for security in automation environments.

The redundant state-of-the-art next generation firewalls not only function as port filters, but also analyze the data on the application level. The services forthcoming in the DMZ, e.g., remote access, file exchange, and active directory, are made available as virtual machines on a separate high-performance virtualization host. Furthermore, the DMZ itself is based on the zero-trust concept, therefore the communication between the virtual machines within the DMZ is effectively prevented and only takes place via the firewalls.

Defense in Depth on a hyper-convergent IT platform

To protect against cyber-attacks, Siemens relies on the holistic Defense in Depth concept, based on the recommendations of IEC 62443. At the heart of the concept is a deeply tiered defense with three levels: Plant security, network security and system integrity. This multiple layer model makes it difficult for attackers to intrude into your system and cause damage.


Features and services for network security and system integrity are already integrated in our Industrial DMZ Infrastructure, serving two of the three layers of the Defense in Depth concept. Thus, you receive cybersecurity out of the box.
