Frequently asked questions
Questions about the results? Talk to a certified expert, free.
Is BreachCheck free?
Yes. Enter your company domain and see the results instantly. No sign-up, no email required.
What is infostealer malware?
Infostealers are malware that quietly copy saved passwords, browser cookies, and session tokens from an infected computer and send them to attackers. The stolen logs are sold and traded in underground markets, where attackers buy access to company systems such as SSO, VPN, email, and code repositories.
What do employee, customer, and third-party results mean?
Employee results are logins belonging to your staff. Customer results are logins people use on your website or app. Third-party results are logins connected to your domain on other organizations' services.
Do you show the stolen usernames and passwords?
No. This free view hides usernames and passwords and shows only counts, dates, affected systems, and device details.
Nothing was found for my domain. Am I safe?
Not necessarily. BreachCheck covers a sample of sources, not every one. A clean result is a good sign, not a guarantee.
My domain is exposed. What should I do?
Reset the affected passwords, revoke active sessions, enforce multi-factor authentication, and check the infected devices. Book a free call and we will walk you through the full picture and how to contain it.
Is my search private?
Your domain is sent to our threat-intelligence data provider to run the lookup. It is not added to the page address or to our analytics.
