Insurance premiums for cybersecurity could grow to $7.5 billion in the next five years, according to a new report.

The study, issued by PricewaterhouseCoopers, found that $2.5 billion was spent on cyberinsurance premiums in 2014, a year in which an average of 100,000 global cybersecurity incidents took place each day. Researchers found that the growing incidence of attacks could cause insurance premiums to surge to $5 billion in 2018, and $7.5 billion in the two years to follow.
