CYBER RESILIENCE / A BUSINESS LEADER’S VIEW

The cyber headlines are loud. Here’s what the evidence says.

UK research and a real business interruption show what’s changing, what the headline figures measure and why recovery belongs on the leadership agenda.

How disruption travelled through the JLR network
JLR systems shut downProduction paused as the company responded to the incident.
  • OperationsA phased restart had to bring production and its dependencies back together.
  • SuppliersDelayed or cancelled orders affected schedules, staffing and payments.
  • DealershipsSystems were intermittently unavailable and the disruption reached retail operations.

Over 5,000 UK organisations affected in the Cyber Monitoring Centre’s model. The estimate spans JLR and other businesses in the network.

The UK picture

The new pressure is speed.

The NCSC describes AI helping attackers find weaknesses and scale familiar techniques. For leaders, the question is whether the organisation can recognise and contain a problem as quickly as it needs to.

The government survey measures breaches or attacks businesses identified in the previous 12 months, including phishing attempts. It is not a measure of severe disruption. Larger businesses may have both more exposure and more ways to notice an attempt.

Use the survey to understand what organisations notice. For investment decisions, ask which services the business depends on and how quickly you would learn that one had been compromised.

The JLR figures

One incident. Two very different cost figures.

Jaguar Land Rover’s results put cyber-related exceptional costs at £196 million for the quarter ending 30 September 2025. The Cyber Monitoring Centre separately estimated £1.9 billion of wider UK financial impact, with a modelled range of £1.6–£2.1 billion.

The wider estimate includes effects on JLR, suppliers and downstream businesses. It depends in part on how quickly output returns. The two figures measure different things and should not be added or used to forecast the cost of an incident elsewhere.

The NCSC describes suppliers facing disrupted schedules, orders and payments. That is the wider lesson: even when your own systems are working, a dependency can interrupt your ability to deliver or get paid.

The supplier lesson runs in both directions. A partner’s outage can stop your fulfilment, and a customer’s outage can suspend demand or delay payment even when your own systems work.

Continuity

Getting systems back and getting the business back are different milestones.

The NCSC describes a return to minimum viable operations: enough essential activity restored safely while the wider rebuild continues. Leadership has to decide which obligations come first and who can approve temporary ways of working.

Consider the effect on customer commitments, suppliers, staffing and cash. A technical restore can be successful while billing, delivery or customer support is still disrupted.

Agree who can open a limited service, what they need to see first and what exceptions must wait. That decision belongs with the people accountable for service, safety and customers.

Example · reopening an essential service
Minimum safe service
Handle urgent requests through a verified route. Log decisions and assign an owner. Pause changes that need unavailable records.
Full service restored
Reconcile the temporary queue, reconnect the case system and confirm that people can safely complete the normal workflow.

Cyber investment

What does the investment make the business better at?

A control that makes intrusion less likely does a different job from a capability that spots an incident or gets a service back. Asking for evidence against each outcome can reveal a gap that a licence list does not show.

The next improvement may be to configure or manage existing tools better, agree who acts on alerts or prove that a priority service can be restored. Insurance can transfer some financial exposure; it cannot restore a service.

A renewal is an opportunity to ask for a recent example of a control working. Evidence from a rehearsed isolation or restoration can reveal whether the issue is coverage, ownership or execution.

What to look for in each capability
ProtectFewer exposed routes
Check which public services and privileged accounts are reachable.
DetectEarlier investigation
Verify that a relevant alert reaches someone who can triage it.
ContainLess interruption
Rehearse isolating an account or service while essential work continues.
RecoverUsable services
Restore a service and have its owner complete a representative task.
