G&G verified business evidence
In the 2025/26 survey, 46% of small UK businesses reported identifying a cyber security breach or attack in the previous 12 months.
The survey covers breaches or attacks organisations could identify and were willing to report, so it may underestimate true prevalence. Small businesses are those with 10 to 49 employees.
Identification-based prevalence may understate the full level of attacks.
