In an upcoming change from Microsoft, they will be removing support for TLS versions lower than 1.2 from the Event Hub. This change is scheduled to take place on Friday 28th February 2025.
Our current Event Hub setup for the WithSecure Elements Identity Security for Entra ID product uses Microsoft's default settings, which is already using TLS 1.2. However, some Event Hubs deployed in the past may have used an earlier version of TLS by default.
We have conducted thorough testing by manually updating our Event Hubs which use the older versions so that they now use TLS 1.2. We are pleased to report that there have been no issues processing data with TLS 1.2.
As a result, we expect no impact on our product when Microsoft updates the default settings to TLS 1.2. There is no need to re-deploy the onboarding scripts after this change. We assume that Microsoft will automatically migrate all Event Hubs to the new default value of TLS 1.2 once TLS 1.0/1.1 becomes unsupported.
