Our opportunities

Use Cases

Protecting yourself

This is the main purpose of LeakCheck. Find out if your data has been compromised as a result of any breach.

Preventing password reuse

According to the results of a survey conducted in 2018 by Google, 65% of users on the Internet use the same passwords for most (or even all) their accounts. With our corporate API you can check whether a password was previously used even before user registered on your website.

Recovering old passwords

Sometimes we forget our credentials and want to get them back. In some cases our service can figure this out.

Users monitoring

Get notified about compromised passwords of your users and force to change them before something bad is happened.

Business monitoring

When it comes to corporate security, a leaked password of at least one of the employees may have tragic consequences for the entire company. We provide several domain monitoring options at once - both manual in your account and automatic with the API or our special solution.
