CA update of 17 October 2021 successfully carried out

The new SwissSign CAs for SSL/TLS and for e-mail/SMIME certificates were activated as announced on 17 October and are now in operation. Please note the new CA hierarchy.

If you have not requested new certificates since then, we strongly recommend installing the new CA certificate chains on your servers, certificate management systems and email gateways. This will ensure a smooth transition. If this is not done promptly, malfunctions cannot be ruled out.

Further details on this and the download URLs for the CA certificates can also be found here:
