PwnedList helps companies prevent data breaches before they occur. We have built the world's largest collection of hacker-stolen account credentials which we use to provide our clients with real-time alerts so they can reduce the number of account hijackings and fraud. We monitor the hacker community every day, automatically collecting all data leaks from websites that hackers frequent. We provide active e-mail notifications for clients so they know about when their credentials have been stolen before the vast majority of hackers. We provide detailed reports so that consumers and businesses alike know who stole their credentials, from where, and what they can do about it. We have an API that allows our data to be a feed for fraud engines and active account management systems.
