Among the businesses that detected breaches, the estimated average cost of all breaches over the last 12
months is £3,480. This is much higher for large firms, at £36,500. The estimated average cost of the single most disruptive breach from the last 12 months is £2,620 across all businesses and £32,300 for large businesses.
