ZUG, Switzerland, Apr 27, 2026 – Siemens Smart Infrastructure has introduced a managed detection and response (MDR) service to monitor and respond to cybersecurity threats across converging IT/OT environments in critical infrastructure. The service uses a 24/7 security operations center to process security data from energy systems, industrial operations, data centers and airports, where increasing alert volumes and limited staffing are creating gaps in threat detection and response.
The MDR service operates through continuous monitoring, incident analysis and response workflows. Security-related data from customer IT/OT systems is securely transmitted to the security operations center (SOC), where events are analyzed, classified and prioritized from false alarms to critical incidents. Based on this process, customers receive recommendations for mitigation and resolution.
Detection rules are maintained, expanded and adapted to threat conditions to support proactive threat detection. The service supports faster identification and handling of cyber threats while maintaining operational visibility across connected systems.
The MDR service is positioned as an alternative to building an in-house 24/7 security operations center. Siemens states that it can reduce initial investment costs by up to 80% and operating costs by up to 50% through a scalable service model. The service aligns with NIS 2 EU cybersecurity requirements.
“Today, energy security is inextricably linked to cybersecurity. This is precisely where we offer our customers crucial support,” said Stephan May, CEO of electrification and automation at Siemens Smart Infrastructure. “Our MDR service combines technology with the expertise of our OT specialists. This allows operators of critical infrastructure to focus on their core business while we protect their systems from cyberattacks. This is the only way we can securely advance the digital transformation and help accelerate the energy transition.”
Hertener Stadtwerke, a municipal utility in Germany, is using the MDR service to protect its operational systems. The service follows cybersecurity principles defined in the Charter of Trust, which sets standards for secure digital infrastructure.
“The requirements for cybersecurity, especially for critical infrastructures like ours, are constantly increasing,” said Stefan Burkert, head of communications technology at Hertener Stadtwerke. “The MDR service from Siemens is a crucial building block for us to meet these requirements and protect our critical infrastructure. It helps us comply with regulations and gives us peace of mind knowing that our systems are monitored by experts at all times. It allows us to focus on ensuring a reliable energy supply.”
The MDR service reflects increasing pressure on operators of critical infrastructure to maintain continuous cybersecurity coverage as IT/OT systems converge. As alert volumes grow and threat patterns evolve, centralized monitoring, incident handling and adaptive detection rules are becoming necessary to manage risk across energy, industrial and data center environments.
