Credit reporting agencies will now be required to register with the state and comply with its cybersecurity regulations, the state Department of Financial Services announced Monday.

The new rules are the state’s response to last year’s data breach at Equifax, a credit reporting agency, that exposed the personal information of 143 million people. If a credit reporting agency is found to have violated the new regulations, the DFS will now have the power to block them from serving New York state residents.
