How much does a data breach cost.

Estimates Put TJX Fiasco at $4.5 Billion. And thats the optimistic number.
The Ponemon Institute, a think tank focused on record privacy and data protection, expects the TJX breach costs to be even higher. They cite costs in the range of $182.00 per record, based on research from November 2006 of the cost of breaches incurred in 31 separate incidents. For TJX, this translates to $8.6 billion.
