The Data Breach Chronology is a comprehensive database of U.S. data breach notifications. Since 2005, Privacy Rights Clearinghouse has tracked data breach notifications. We collect breach notifications from every state currently sharing breach notification data, as well as the Department of Health and Human Services, creating a standardized searchable database of over 75,000 notifications affecting billions of individuals. This listing is updated monthly with the latest breach data.

This single-user license gives you a point-in-time snapshot of the complete database — the version current at time of purchase. Your download link stays active for one year so you can re-download your version in any format, anytime.
