UK sees 50 % surge in “Highly Significant” cyber incidents

In its latest annual review, the UK’s National Cyber Security Centre (NCSC) reported a 50 % rise in cyber incidents classed as “highly significant” over the past year, handling 429 incidents in total, of which 18 had serious national impact.

Those incidents targeted essential services, government functions, and major commercial brands like Marks & Spencer, Co-op, and Jaguar Land Rover, forcing disruptions across supply chains.

The NCSC has urged business leaders at all levels to treat cyber resilience as a board-level priority, warning that if systems were to go dark, organizations must ask: could critical operations like payroll, inventory, or manufacturing continue?

This upward trend underscores that incident avoidance is only part of the picture; organizations must invest in robust recovery, redundancy, and continuity.

 The pressure now falls on executives, not just technical teams, to own cyber risk, embed scenario planning, and demand resilience as part of core strategy.
