"There are no corporate clients today that don't have insurance on their buildings or cars, but I think that within a very few years it will be just as evident that you should insure against cyber crime," Tryg chief executive Morten Hubbe told Reuters. According to Tryg, there was a spike in demand for cyber insurance following the "Wannacry" ransomware attack, which affected more than 300,000 computers in May. Hubbe told Reuters that he projected around 50% of Tryg's corporate clients would buy cyber insurance by 2020, and that figure would reach 90% "a couple of years" after that. "The biggest risk to us is that significantly more customers get hit than we believe, and that gives us a huge economic loss," he told Reuters.
