Telekom Security: Transition Plan for Existing Dual-Purpose Roots

ASSIGNED Deutsche Telekom Security GmbH

AI Summary

Telekom Security is implementing a transition plan for its dual-purpose roots, with new TLS Roots already included in the Chrome Root Store. They plan to migrate TLS certificate issuance to these new roots by April 2027, while S/MIME certificates will transition to dedicated roots by the end of 2026. However, due to legacy applications that cannot be updated, Telekom Security will continue issuing TLS certificates under the old Root CA for a limited group of customers. The removal of the old Root CA from browser Root Stores is planned for May 2027.
