Case Study: European Heating Supply Company achieves OT visibility across 200 sites with Nozomi Networks

European Heating Supply Company monitors 200+ sites with Nozomi Networks

The customer, a European heating supply company, faced challenges in securing its operational technology (OT) network, which supplied heat to over 300,000 customers. The OT Network Administrator needed actionable insights into device vulnerabilities, particularly concerning PLCs susceptible to threats like Stuxnet, and sought to increase cybersecurity resilience in preparation for anticipated NIS regulations. They partnered with vendor Nozomi Networks to address these concerns.

Nozomi Networks implemented its Guardian sensor and Threat Intelligence services to provide comprehensive OT and IoT visibility and security. The solution delivered real-time visibility across the company's entire 200-site infrastructure, identified PLC vulnerabilities and network connections, and enabled the demonstration of good cybersecurity practices. This allowed the company to cost-effectively monitor its entire operation with a single device and a one-person OT team, proactively improving its security maturity and preparing for compliance.
