Our system finds any attempts to alter certificates and marks possible fakes, ensuring that only real certificates get a positive verification.

When someone validates a certificate, CertLister shows important details to the verifier, such as the recipient’s name, certificate title, issuing organization, issue date, and current status. You can control which information appears during verification to balance transparency and privacy as needed.
