Late last year DigiCert completed their acquisition of the Symantec Group, including its subsidiaries GeoTrust, Thawte, and RapidSSL. This was completed after security concerns were raised about the administration of the Certificate Authority run by Symantec, which resulted in threats from Google to remove them from the validated certificates list in their Chrome browser. As a result of these changes, and DigiCert requires the migration of all previously issued Symantec Group certificates over to its own DigiCert CA Root.
What does this mean for me? If you have a Symantec Group SSL certificate (Symantec, GeoTrust, Thawte, or RapidSSL), you will need to re-issue or renew your certificate.You should've already been in contact with your SSL provider to get this done, however, if not, it's best to get this done ASAP. The Beta release of Google Chrome 70 has just passed (13th Sept 2018), which now marks all Symantec Group certificates as Insecure. The Full release of Google Chrome 70 is scheduled for the 16th of October, 2018. This is where everyone using Chrome should be prompted to upgraded. I'm a SenseICT SSL Customer, what does this mean for me? If you use SSL certificates outside of your hosted infrastructure you will have already been contacted to arrange re-issuance of your certificate. If you're a hosted infrastructure client you don't have to do anything, we've already re-issued and installed your new certificate.
