Enhance cybersecurity in low-voltage power distribution

Low-voltage power distribution systems face significant cyber risks that can disrupt infrastructure and cause large losses. Siemens cybersecurity solutions protect systems through defense-in-depth strategies, secure design, and continuous vulnerability management.

Protecting low‑voltage power distribution from OT/IT cyber threats

Connecting OT to IT unlocks efficiency but it also creates critical vulnerabilities. While cybersecurity is largely established in IT environments, many OT systems still lack mature protection. Direct internet exposure introduces single points of failure: one breach can shut down operations and disrupt entire value chains. Unlike IT, many OT systems lack mature cybersecurity, making them easy targets. Without integrated protection, attacks can cascade across infrastructure – causing downtime, safety risks, and major financial loss.

Support compliance & standards

Aligned with IEC 62443 and industry best practices, cybersecurity solutions help operators meet regulatory requirements and ensure systematic risk mitigation across the lifecycle.

Protect your electrical OT – Take a holistic cybersecurity approach

A single measure isn’t enough to provide security, even in a low-voltage power distribution: You need a systematic, end-to-end approach to build up multiple barriers and firewalls. Building on the Defense-in-Depth strategy, we provide multilevel protection against cyberattacks, as recommended by the international standard IEC 62443 – from physical protection to plant security, network security, and system integrity for every single field device.

Embed cybersecurity as planner, system integrator, or operator

The IEC 62443 standard affects all stakeholders: operators, system integrators, or manufacturers. They all have their areas of responsibility. That’s the only way to ensure cybersecurity holistically, with an end-to-end system approach.

Everyone is encouraged to incorporate and practice cybersecurity in their processes and organizational structures. Electrical systems are like cars: When vehicles are developed, the key safety functions are included as part of the design. When the vehicle is built, the safety functions are calibrated, set, and tested. And when it’s running, it’s checked to ensure the safety functions are active and will work reliably in an emergency.

Planners: Plan for cybersecurity from the start

It’s important to factor in cybersecurity right at the planning stage.

We provide you with system tender specifications, cybersecurity functions in the product tender texts, and consultation by our experts.

Use Case

System integrators: Cybersecurity during commissioning

As a system integrator, you have to implement a secure system based on secure products and then pass it on to the operators. Cybersecurity must be comprehensively integrated when you implement and commission a switchboard. You combine secure individual components to form a secure system, test it, and then hand it over to the system operator.

We’re there to help with professional knowledge, software tools, and application examples.

Operators: Protect running systems against attacks

As an operator, you are required to create awareness and understanding within the entire organization and all its people: You must work with system integrators to define processes, such as which actions may be taken by whom, when, and on what authority. You have to fix any vulnerabilities which might occur during the operational phase.

You are also obliged to ensure secure operation. Throughout the entire lifecycle, you keep operations secure and up to date by applying updates to maintain state-of-the-art protection.

We help maintain your devices’ cybersecurity for the long term with vulnerability management and new firmware releases.
