Only 41 per cent of businesses can say with certainty that data leaks do not happen to them. According to the research there were around 24,000 leaks last year, but only 5500 leaks were reported to the Autoriteit Persoonsgegevens. Many businesses admit that they failed to report a leak because the impact of the leak was limited or unclear. A second important reason for not reporting a data leak is the potential damage to the reputation of the business. Fifteen per cent of businesses claim not to have reported a leak in order to prevent further abuse of the data leak. Primary cause of a data leak: loss of laptops, pc’s, smartphones or USB sticks.
