GlobalSign has changed the AlphaSSL and AlphaSSL Wildcard root certificate hierarchy from R1 to R6

As of January 29, 2024, the GlobalSign Certificate Authority will migrate to a new certificate chain with the R6 root. The update affects AlphaSSL and AlphaSSL Wildcard and the reason for it is that Mozilla will stop supporting the GlobalSign R1 root certificate due to new security requirements

What to do.

If you have the AlphaSSL and AlphaSSL Wildcard certificates:

• Until January 29, 2024. You don't need to do anything. The certificates will work until the end of their validity periods.
• After January 29, 2024. If you purchased AlphaSSL and AlphaSSL Wildcard, please specify which certificates it has provided. You may need to download the root and intermediate certificates required for installation on the GlobalSign website →

Important. R6-signed AlphaSSL and AlphaSSL Wildcard certificates will not work on operating systems released before Windows 10 or Android 10, or in Firefox 63, IE 11, or Opera 28 browsers. To see the full list of software that supports the new root certificates, visit the GlobalSign website →
