Siemens Smart Infrastructure has introduced a Managed Detection and Response (MDR) service aimed at strengthening cyber resilience for energy providers and operators of critical infrastructure, including data centres and airports.
The launch comes as organisations face growing cybersecurity challenges driven by the convergence of IT and operational technology (OT). This shift is generating a surge in security alerts, placing pressure on internal teams that often lack the resources and round-the-clock expertise required to manage complex threat environments.
Siemens’ MDR offering is designed to address these gaps through a fully managed, 24/7 service model. By outsourcing security operations rather than building in-house capabilities, companies can significantly reduce both upfront and ongoing costs while maintaining compliance with regulatory frameworks such as the NIS 2 Directive.
The service provides continuous monitoring and analysis of IT and OT environments, enabling faster identification and response to potential threats. Security data from client systems is collected and transmitted to a central Security Operations Centre, where events are assessed, prioritised and categorised. From there, customers receive targeted recommendations to mitigate risks and resolve incidents efficiently.
By combining automated detection with specialist expertise, the system is able to distinguish between false alarms and critical incidents, helping organisations focus on genuine threats. Detection protocols are continuously updated to reflect evolving cyber risks, ensuring a proactive rather than reactive approach to security.
Siemens states that the MDR service can accelerate response times significantly, allowing threats to be addressed more quickly than traditional in-house models. It also enables operators to maintain secure operations without diverting resources from core business activities.
The solution is already being deployed by early adopters, including Hertener Stadtwerke, which is using the service to protect its operational systems. For utilities and other infrastructure providers, rising regulatory requirements and the increasing sophistication of cyber threats have made robust security frameworks essential.
The MDR service aligns with Siemens’ broader cybersecurity strategy, which emphasises trusted standards and scalable solutions to support digital transformation. It also reflects the principles of the Charter of Trust, an initiative promoting stronger global cybersecurity practices and collaboration.
As industries continue to digitalise and integrate connected technologies, cybersecurity is becoming a central pillar of operational resilience. Siemens’ latest offering aims to provide a practical and cost-effective solution for organisations seeking to secure complex infrastructure while navigating an evolving threat landscape.
