How will this affect GlobalSign?

GlobalSign Root R3	March 15, 2026	April 15, 2027
GlobalSign Root R5 (ECC)	March 15, 2028	April 15, 2029

What's Changing?

The following products will be modified as part of disabling TLS issuance from Root R1:

• On October 30th, 2024, we will switch the CloudSSL RSA CA from the CloudSSL CA to the current TLS OV CA.  See this page for details: https://support.globalsign.com/ca-certificates/intermediate-certificates/cloudssl-intermediate-certificates

• On January 29, 2024, we will switch the AlphaSSL CA to a new CA that is issued from Root R6. See this page for details:
  https://support.globalsign.com/ca-certificates/intermediate-certificates/alphassl-intermediate-certificates

• Starting in September and concluding by February 2024, GlobalSign will individually transition a small set of existing legacy TLS OV customers that are using a TLS OV CA issued by Root R1 to using the "GlobalSign RSA Organization Validation CA-2018".  See this page for details:  https://support.globalsign.com/ca-certificates/intermediate-certificates/organizationssl-intermediate-certificates

We will announce plans for transitioning away from GlobalSign Root R3 as we get closer to 2026.

Products Impacted:

• TLS: AlphaSSL, CloudSSL, and some TLS OV customer-specific configurations
