Data Breach incidents cost companies $197 per compromised customer record in 2007, compared to $182 in 2006. Lost business opportunity, including losses associated with customer churn and acquisition, represents the most significant component of the cost increase. Breaches by third parties were more costly than breaches by the enterprise itself. Notification costs fell 40 percent, decreasing from $25 per customer in 2006 to $15 in 2007. The Ponemon Institute study tracks a wide range of cost factors, including legal, investigative and administrative expenses.”]
