New issuer certificates at the Shared-Business-CA In the Shared-Business-CA we will roll out the two new Sub-CA certificates of the Shared-Business-CA at the end of Q1/2022. The new certificatesTeleSec Business CA 21: for all certificate types (except server) under public root TeleSec Business TLS-CA 21: for server certificates under public root. should already be downloaded from the following URLhttps://www.telesec.de/de/root-programm/informationen-zu-ca-zertifikaten/intermediate-zertifikate/and distribute it in your environments. Notes:All certificates issued under the issuer "TeleSec Business CA1" are still valid until they expire or are revoked. After rolling out in the shared business CA, the new certificates will no longer be issued under the "TeleSec Business CA1", but - depending on the certificate type - will be issued as described above. Browser: you do not need to do anything at this point because the CA certificates are automatically transferred to the trusted root store. For issuer certificates under an internal root nothing changes at the moment. We will implement the changes shortly and inform all our customers about this again. Ihr Team der SBCA.
