2025
This database identifies each entity since April 14, 2018 which has notified the Delaware Attorney General of a data security breach potentially affecting Delaware residents, along with the date(s) of the breach, the date when the breach was reported to the Delaware Attorney General, the number of Delaware residents potentially affected by the breach, and (if available) a sample of the notice provided to potentially affected Delaware residents.
Please note that for some data security breaches, the entity that sends the breach notice is not the entity that experienced the breach. This may happen, for example, when a web service provider that stores or maintains data on behalf of an online retailer suffers a data security breach, or a retailer suffers a data breach that includes the credit card information of a bank’s customers.
