Kaspersky Fraud Prevention 4.0 for Endpoint verifies authenticity of websites by ensuring that the digital certificate that is used to establish a secure connection corresponds to the address of the requested website.

During a certificate check, the following message may appear: "The certificate obtained when establishing secure connection does not match the original certificate". The reasons to an invalid certificate might be the following:

  • Revoked certificate:
    • Certificate or its signature is revoked.
    • Failed to check the revocation status.
  • Fake certificate:
    • The certificate is subscribed illegally.
  • Certificate chain is broken:
    • The chain consists of one self-signed certificate.
    • The chain does not end with a trusted root certificate.
    • The chain contains certificates which are not meant to sign other certificates.
    • Root or intermediate certificate has expired or its time has not come yet.
    • The chain was not built.
  • The domain specified in the certificate does not match the website to which the connection is established.
  • Detected certificate usage violations:
    • The certificate is not meant to confirm the node authenticity.
    • Usage policies violation.
  • Certificate time violation.
    • Action time has expired.
    • Action time has not come yet.
  • Certificate structure is broken:
    • The structure is damaged.
    • Signature checking error.

If such a notification is displayed, the Kaspersky Lab specialists do not recommend to continue working with the website.

If the notification appears in Mozilla Firefox, try another browser (for example, Internet Explorer).
