FAQ
What is a data breach checker?
A data breach checker is a free tool that scans your domain or email address against databases of known data breaches. Our data breach checker searches over 15 billion exposed records from 50,000+ confirmed breaches to find if your company’s credentials have been compromised.
How does the data breach checker work?
Simply enter your company domain (e.g., yourcompany.com) and click search. Our data breach checker instantly scans all known breach databases to find any exposed email addresses, passwords, or personal data associated with your domain. Results are displayed within seconds.
What should I do if my domain appears in a breach?
If the data breach checker finds your domain in a breach:
Identify affected employee accounts
Force password resets immediately
Enable two-factor authentication (2FA)
Check for unauthorized account access
Consider Security Awareness Training to prevent future incidents
