Case Study: Falu Energi & Vatten achieves centralized visibility and IT/OT integration with Fortinet

Swedish Energy and Water Utility Enhances Safety and Reliability Through IT/OT Integration as Part of Ongoing Digital Transformation

Falu Energi & Vatten is a municipally owned Swedish utility serving Falun with electricity, heating/cooling, water, sewage and recycling. With about 200 employees and SEK 770M turnover, the company began a digital transformation in 2009 and faced growing security and visibility challenges: legacy OT devices across 200 remote sites, inadequate firewall capabilities, the need for traffic segmentation and zero‑trust access, and resilience for equipment in harsh environments.

Falu Energi & Vatten deployed the Fortinet Security Fabric—including FortiGate NGFWs, rugged FortiSwitches, FortiAP, FortiClient, FortiAuthenticator, FortiMail, FortiSandbox, FortiManager and FortiAnalyzer—to deliver centralized visibility, control and automation. The solution enabled staged IT/OT integration, stronger authentication, improved malware and phishing protection, discovery/removal of risky software, and greater safety, reliability and efficiency across the company’s network and operational sites.
