Data breach cost rises 12% over the past 5 years: IBM Study

IBM Security announced the results of its annual study examining the financial impact of data breaches on organizations. According to the report, the cost of a data breach has risen 12% over the past 5 years and now costs $3.92 million on average. These rising expenses are representative of the multiyear financial impact of breaches, increased regulation and the complex process of resolving criminal attacks.

The financial consequences of a data breach can be particularly acute for small and midsize businesses. In the study, companies with less than 500 employees suffered losses of more than $2.5 million on average – a potentially crippling amount for small businesses, which typically earn $50 million or less in annual revenue.

The report also examined the longtail financial impact of a data breach, finding that the effects of a data breach are felt for years. While an average of 67% of data breach costs were realized within the first year after a breach, 22% accrued in the second year and another 11% accumulated more than two years after a breach. The longtail costs were higher in the second and third years for organizations in highly-regulated environments, such as healthcare, financial services, energy and pharmaceuticals.

“Cybercrime represents big money for cybercriminals, and unfortunately that equates to significant losses for businesses,” said Wendi Whitmore, Global Lead for IBM X-Force Incident Response and Intelligence Services. “With organizations facing the loss or theft of over 11.7 billion records in the past 3 years alone, companies need to be aware of the full financial impact that a data breach can have on their bottom line –and focus on how they can reduce these costs.”

The study found that data breaches which originated from a malicious cyberattack were not only the most common root cause of a breach, but also the most expensive.
