Making stealer infections worthless.

The Passguard team
  • Find

    We help hundreds of security teams find stolen credentials, active sessions and cookies from compromised devices.

  • Test and revoke

    Our technology tests whether stolen access is still active and revokes it before it can be abused.

  • Built in Europe

    We are built and hosted in Europe and never pay cybercriminals for data.
