Reporting a certificate problem

You would like to inform us about a problem with a TLS/SSL or S/MIME certificate issued by us? This is not a technical problem, such as a faulty installation, but a non-compliant certificate according to the CA/B forum’s TLS Baseline Requirements and/or EV guidelines or  S/MIME Baseline Requirements?

Then please report this to us. To do so, fill out the form below entitled "Reporting a problem with a certificate issued in accordance with the CA/Browser Forum" and send us the completed form to the e-mail address specified in the PDF form with the subject: "Reporting a certificate problem".
