Ponemon Institute Direct Costs Estimate ¹

$1,920,000,000.00

Note that these estimates are based on the Ponemon Institute's 2009 direct costs figures from their 2009 Annual Study: Cost of a Data Breach. We multiply $60.00 by the number of records to obtain this figure. Keep in mind that depending on the breach, the direct costs are not always suffered by the breached organizations. In the case of credit card number breaches, the direct costs can often be suffered by banks and card issuers. Also note that this is only an estimate.
