What the Jaguar Land Rover attack taught British boards about cyber risk
The Jaguar Land Rover attack showed British boards that a cyber incident is not an IT problem. It is a business continuity problem that can stop a company and ripple through its entire supply chain.
The attack began at the end of August 2025. Jaguar Land Rover shut down its systems to contain it, and production stopped for around five weeks. It has since been described as the most damaging cyber event in British history, with an estimated cost to the UK economy of £1.9 billion.
For boards, three lessons stand out.
Cyber risk is operational risk. The impact was not data loss alone. Factories stood idle, suppliers lost orders and dealerships felt the effects. A cyber incident can halt the thing a business exists to do.
Dependence runs through the supply chain. Smaller suppliers were exposed through no fault of their own. Boards need to understand not only their own resilience, but that of the businesses they rely on.
Recovery is a leadership test. How quickly a company can restart, and how clearly it explains what is happening to staff, suppliers, customers and the public, shapes how an incident is remembered.
That last point is where communications comes in. When a major incident is under way, journalists look for people who can explain what has happened, what it means and what organisations should do about it. Informed, measured voices are valuable in those moments, and they are rarer than they should be.
The lesson for cyber security and technology businesses is a practical one. Boards are now actively asking what resilience means for them. Specialists who can explain that clearly, without hype, will be heard.
That means being ready before an incident, not after: knowing which subjects you can speak about credibly, having a considered view and being known to the journalists who cover them.
For anyone working in cyber security, the conversation has moved from “if” to “how prepared are you”. The experts who help shape it are the ones boards, and the media, will turn to.
