TLS/SSL: Scheduled Root Transition for SwissSign Certificates in April 2026
SwissSign Gold CA – G2 retires from Chrome and Mozilla. For almost all customers, no action is required.
On 15 April 2026, Google Chrome and Mozilla Firefox will retire the legacy SwissSign Gold CA – G2 root from their TLS trust stores. This is part of the browser vendors' annual clean-up of older public TLS roots and is not linked to any incident or compliance finding.
For almost all SwissSign customers, no action is required. The replacement root SwissSign RSA TLS Root CA 2022 – 1 is already included in both the Chrome and Mozilla trust stores, and TLS certificates continue to be valid without reissuance. Only a small number of non-standard setups, such as certificate pinning tied to Gold G2 or legacy strict chain-walking validators, should be reviewed and updated before the date.
