Last year Google Chrome created a plan to reduce and remove trust (by showing security warnings in the Chrome browser) for all Symantec, Thawte, GeoTrust, and RapidSSL-issued SSL/TLS certificates.
Towards the end of 2017, DigiCert took over validation and issuance for all Symantec Website Security SSL/TLS certificates. This includes certificates for Symantec and all its subsidiary CAs: Thawte, GeoTrust, and RapidSSL. Going forward, all new and reissued Website Security certificates are issued by DigiCert and are trusted by Google Chrome.
The new certificate chain DigiCert created does not interfere with your current certificate trust among browsers. The chain also establishes trust for your replacement certificate with Google Chrome (and other browsers) going forward.
DigiCert will replace all affected certificates at no cost.
If your SSL/TLS certificate was issued before June 1, 2016 and expires on or after March 15, 2018, replace it before March 15, 2018.
If your SSL/TLS certificate was issued after June 1, 2016 (and before December 1, 2017) and expires on, or after September 13, 2018, replace it before September 13, 2018.
Don’t wait until the deadlines loom to replace your affected certificates. Domains and organizations need to be validated before we can issue certificates. And don’t forget you’ll need time to install the new certificate so your website avoids Google Chrome
