Hello Tealium Customers,
On March 09, 2022, Tealium will be upgrading our TLS endpoints to support more current TLS ciphers (no changes to TLS version will be made, we still only support TLS 1.2). No customer impact is expected.
The following TLS 1.2 ciphers are the only ciphers that will be supported once the change is made:
TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
If you have any concerns, please reach out to your customer success team.
