We were engaged by an international organisation operating in more than twenty countries across Europe and Central Asia that manages dozens of sites, data centres, and manufacturing facilities. Its IT and OT infrastructure supports research, logistics, manufacturing, and commercial operations in regulated industries. Rapid expansion and decentralised management created a need to unify cybersecurity and establish consistent processes, rules, and measurable metrics across all countries.
Prior to our engagement, cybersecurity was fragmented. Technologies and maturity levels varied significantly, central coordination was lacking, there was no unified approach to suppliers, patching, or risk assessment, and inconsistent security awareness increased operational risk. The organisation required a consistent, scalable, and continuously maintained solution.
The objective of the project was to establish Security as a Service enabling centralised security governance while preserving local accountability, ensuring continuous monitoring and incident coordination, defining measurable KPIs, and providing regular management reporting. At the same time, the service supports communication and knowledge sharing between regional teams and meets the requirements of NIS2, GDPR, ISA/IEC 62443, and ISO/IEC 27001.
The project began with a comprehensive security assessment across individual regions and the alignment of policies, directives, and processes into a unified framework. This included maturity evaluations of sites against ISA/IEC 62443 and ISO/IEC 27001, enabling the definition of a baseline cybersecurity posture and a development roadmap for each location. A key element was the establishment of a network of local Security Officers responsible for policy oversight, incident coordination, and reporting to the global Security Manager. IRON OT provides central methodological guidance and facilitates regular coordination meetings across the network, ensuring a consistent response to emerging threats.
Security is managed through defined KPIs tracking incident volumes and response times, patching and vulnerability status, the effectiveness of security testing, and employee training completion. Monthly reports provide management with visibility into trends, performance, and fulfilment of objectives. The service also includes centralised security event monitoring, end-to-end incident management, cross-border incident coordination, and post-incident analysis.
After more than one year of operation, the organisation has achieved a unified security governance framework across IT, OT, and cloud environments, an effective network of Security Officers, transparent visibility into its security posture, and faster incident response, with an average response time reduction of more than 40%. The organisation demonstrates measurable compliance with NIS2, ISA/IEC 62443, and internal standards, alongside increased security awareness and engagement of local teams.
The project confirmed that Security as a Service is an ideal model for multinational organisations requiring consistent security management across regions, central visibility combined with local accountability, and cost optimisation. By combining expert leadership, a distributed network of Security Officers, KPI-driven governance, and structured reporting, the client gained control over its cybersecurity posture and the ability to demonstrably meet regulatory requirements.
