Breach Check API

Check to see if your users or employees are exposed in data breaches that may leave them vulnerable to account takeover and other types of cyber crime. Our dataset contains over 14.5 billion data records, recovered from data breaches and leaks all over the world.

Companies amass huge amounts of data which makes them a prime target for hackers. Cyber criminals publicly post or privately trade hundreds of millions of stolen data records every month on the Dark Web, details of which include username and password combinations, dates of birth, credit card details, government identity documents and more. Using this stolen information, criminals take over user accounts for online banking portals, social media and online dating profiles, online retail accounts, business email accounts and more.
