Concerns are increasing over the UK’s reliance on energy grid technology supplied by companies linked to Iran and China, with growing pressure on authorities to remove these entities amid fears of cyber threats and geopolitical influence. Many control systems and communications platforms within the National Grid feature hardware and software from internationally ambiguous suppliers, complicating regulatory compliance and raising the risk of remote manipulation or data breaches.
Completely replacing suspect equipment is a costly and complex prospect. More feasible measures include segmenting networks, rigorous vendor transparency via detailed SBOMs, and focused monitoring of systems for anomalies. As technical teams prioritise operational resilience, the challenge is to balance secure infrastructure needs against global supply chain realities.
