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

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 →
