Information Security
and Data Privacy

Protecting business, employee, and customer information is a top priority at Discover. Identity fraud cost U.

We also offer Identity Theft Protection, a fee-based service that monitors participating customers’ personal information online and at three major U.S. credit bureaus, alerts customers when suspicious activity is detected, and provides access to specialists to resolve issues. This affordable and comprehensive protection product works hard, offering benefits such as:

The Company recognizes the National Institute of Standards and Technology (“NIST”) definition of Information Security as being the protection of information and information systems from unauthorized access, use, disclosure, disruption, modification or destruction.

Discover Freeze it®
