"This is one of the largest data breaches in history, yet most of the people affected by the Epsilon breach had never heard of that company before this week," Franken said a . "We need to give Americans more awareness about who has their information and greater ability to protect it."

Blumenthal went a step further and called for answers from Epsilon's CEO Bryan Kennedy with regard to how the company plans to help consumers in the coming months and how it will prevent this type of data from being compromised in the future. Last week, Blumenthal wrote to Kennedy, expressing concern and asking for answers to questions regarding the breach. Blumenthal had previously written to U.S. Attorney General Eric Holder to request an investigation into the breach, according to the senator's website.

"This data in the wrong hands can be extremely damaging to the financial well-being of a number of consumers across Connecticut, some of whom might not know their identifying information has been compromised," Blumenthal said. "Epsilon owes it to these consumers to provide them with tools to ensure the safety of identification and financial information, and also to take serious steps toward preventing these types of breaches in the future."
