- Be cautious of unexpected messages asking for credentials or verification codes.
This is a one-time CyberFence check against a publicly searchable breach index, not a complete security assessment. Private, hidden, or unindexed breaches may not appear. A match does not prove your current password was exposed or that an account is currently being accessed.
A clear first step

Choose what comes next.
Your free check includes match status, reported breach names, and general security guidance for one email at a time. Detailed reports and ongoing monitoring are paid features.
It does not test your password, recover an account, or enroll you in alerts. No account or payment is needed for the free check.
Before you check
What does a match mean?
CyberFence found your email listed in a known breach source. It does not tell us whether your current password is exposed or your account is currently being accessed.
Does no match mean my accounts are safe?
No. It means no match was returned in the checked index at that time. No index covers every breach or every affected account.
Will I receive marketing emails or alerts?
No. This tool does not create an account, subscribe you to marketing, or start ongoing monitoring. It shows a one-time result only.
Why might the check be unavailable?
The service has shared capacity and abuse-prevention limits. If a check cannot be completed, we say so. An unavailable or rate-limited check is never presented as no matches.
