Hidden Costs Drive up Data Breach Expenses

In a new study, IBM Security and Ponemon Institute found that the average cost of a data breach globally is now $3.86 million, representing a 6.4% increase from the 2017 report. Much of it comes from hidden costs in data breaches—lost business, negative impact on reputation and employee time spent on recovery—which are difficult and expensive to manage.

For example, the 2018 study found that one-third of the cost of "mega breaches" (more than one million lost records) was derived from lost business.
