Perimeter E-Security today unveiled the results of its annual U.S. Data Breach Study, a review of the scope and impact of data security breaches that occurred in the past year.

“While 2009 had the fewest number of data breach incidents reported in the last four years, there was a dramatic increase in the average number of records lost in each incident and a rise in the costs associated with a breach,” said Kevin Prince, Chief Technology Officer, Perimeter E-Security. “The most disturbing trend is that almost half of publicly disclosed data breaches do not include the total number of records compromised.”
