In 2007, SUNET joined the TERENA Server Certificate Service (SCS), enabling us to provide server certificates issued by GlobalSign. That service was active until April 9, 2010 and was 2008 replaced by the TERENA Certificate Service (TCS) with server and personal certificates provided by Comodo CA Limited.

From July 2015 we are using the new Trusted Certificate Service (TCS) tenderered for by TERENA (known as GÉANT after the October 2014 merger with DANTE and a name change in May 2015). This time, Digicert has been chosen as the provider. This service is available from 2015-04-10 and is the only one offered from 2015-07-01SUNET is part of the GÉANT TCS service since 2007 (although it was TERENA SCS back in those days). The backend for the service has been provided by GlobalSign, Comodo, DigiCert (2015-2020) and Sectigo (2020-). SUNET customers can become members of the SUNET TCS service without extra charge and get server, client and code signing certificates.
