The number of high-risk breaches nearly halved in the first three months of the year, falling to seven in the first quarter of 2026 from 12 the previous quarter, according to the Bailiwick’s data authority.
The same period has also saw 65 personal data breaches reported in the first quarter, up from 61 in the previous quarter, according to The Office of the Data Protection Authority (ODPA).
’Customers’ was the most commonly affected category (32), followed by ‘Staff or Volunteers’ (15), whilst a ‘loss of confidentiality’ (40) was the most commonly reported potential harm.

“Notwithstanding the continuing high volume of breach incidents, there are some very encouraging signs,” said Data Protection Commissioner Brent Homan.
“The fact that the severity of compromises has decreased and that breaches are increasingly being detected from within organisations points to reduced harms that are mitigated more quickly,” he added.
