For a longer transition period, we (IT + CA + DFN-PKI) offered worldwide recognized digital IDs (certificates) from two different providers.
The formerly offered digital IDs with “Global” certificates are based on the “T-TeleSec GlobalRoot Class 2” root certificate from T-Systems Enterprise Services GmbH.
This offer expired in December 2022.
The currently offered digital IDs with “TCS” certificates from the Trusted Certificate Service (TCS) of the pan-European research network GÉANT are based on the root certificates of Sectigo.
The digital IDs „TCS“ have three advantages: For many users, no new ID checks are necessary, there is no paperwork, and digital IDs from servers can be automatically renewed via ACME.
