Is BreachCheck free?
Yes. Enter your company domain to see instantly whether it is exposed. No sign-up needed. If it is, you can get the detailed report free by email.
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. The page only tells you whether your domain is exposed. The detailed report (counts, dates, affected systems, and device details) is sent only to an email address at the domain you checked, and never includes usernames or passwords.
Why must the email address match the domain?
Exposure details are sensitive. Sending the report only to an address at the checked domain means it reaches people at that company, not anyone who types in its name.
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. If you ask us to email you the report, we use your email address to send it and may follow up about the findings.
