AtkinsRéalis

AtkinsRéalis operates at the intersection of critical infrastructure and digital systems - transportation networks, water utilities, energy grids, and nuclear power facilities across 50+ countries. With over 36,000 professionals on staff, the company's attack surface spans everything from legacy OT environments in power plants to modern cloud-connected digital twin platforms. That's a threat model that demands serious attention: nation-state actors targeting energy infrastructure, supply chain compromises in industrial control systems, and the expanding exposure that comes with AI-powered operational tooling. The company builds and deploys digital twin technology and AI-driven solutions across its engineering verticals, meaning cybersecurity teams aren't just protecting corporate assets - they're working to secure the systems that model and manage physical infrastructure in real time. The stakes are concrete: a compromised digital twin in a nuclear or energy context isn't a data breach headline, it's an operational integrity problem. Defenders here need fluency in both traditional IT security and the specialized protocols governing industrial control systems. AtkinsRéalis positions itself at the convergence of engineering services and nuclear expertise, connecting people, data, and technology to transform infrastructure and energy systems. The cybersecurity function operates within that frame - securing sustainable engineering projects and the digital layers that increasingly define how critical infrastructure is designed, monitored, and operated at global scale.
