Stedin

Stedin is one of the Netherlands' largest grid operators, managing the electricity and gas networks that power more than 2.3 million customers across South Holland, Utrecht, and Zeeland. With approximately 5,500 professionals, the company sits at a critical junction: its infrastructure is both a target and an enabler of the energy transition. The attack surface is physical and digital - operational technology controlling grid flow, IT systems handling customer data, and the expanding perimeter created by smart meters, distributed energy resources, and grid-edge devices connecting to the network. For a cybersecurity professional, the threat model here is layered. Nation-state actors and sophisticated criminal groups have well-documented interest in energy infrastructure. The convergence of legacy OT systems with modern IT creates exploitable seams. Meanwhile, the rapid digitization of the grid - driven by the energy transition - means new attack vectors are introduced faster than traditional utility security postures evolve. Stedin's domain spans grid management, energy infrastructure, and the integration challenges that come with connecting millions of endpoints to critical networks. The company emphasizes collaboration with policymakers, municipalities, market participants, and customers. Employees are described as personally invested in the energy transition. This isn't abstract corporate mission language in this context - it means security teams are working to protect infrastructure that is actively being rearchitected. The social responsibility angle is concrete: a compromised grid operator doesn't just lose data; it loses power supply to entire provinces.
