Breach Classification

Some breaches may be flagged as "unverified". In these cases, whilst there is legitimate data within the alleged breach, it may not have been possible to establish legitimacy beyond reasonable doubt.

Unverified breaches are still included in the system because regardless of their legitimacy, they still contain personal information about individuals who want to understand their exposure on the web.
