Cyber security now a matter of ‘business survival and national resilience’

An annual review has revealed that the UK’s threat landscape for cyber attacks has ‘intensified’.

The findings show that with the number of cyber attacks growing so significantly, organisations must have the necessary precautions in place to protect themselves.

The report also highlighted that while small and medium sized businesses might presume that they are immune, the scale of attacks is rising across the board.

A sharp increase in ‘nationally significant’ cyber incidents

The National Cyber Security Centre’s (NCSC) latest annual review shows that in the 12 months to September 2025, the agency dealt with 204 ‘nationally significant’ cyber incidents – this is equivalent to an average of four such events every week.

This also marks a sharp increase from the 89 nationally significant incidents handled in the previous year.

Other findings show:

• Cyber attack disruption is no longer a possibility; it is now an increasing probability for UK organisations.
• More than half of the reported incidents were deemed ‘national significance’.
• Business leaders are being urged to treat cyber resilience as a top-tier board-level priority, not just an IT concern.
• Organisations must act on the NCSC’s advice to make themselves ‘as hard a target as possible’, incorporating governance, investment, preparedness, and incident simulation.
• Cyber resilience must no longer be seen as optional; every organisation must treat it as a core strategic priority.
