How to check TLS-Version?

Michael Schmidt 46 Reputation points


I've got a mail saying "If you have resources that interact with Azure services and still use TLS 1.1 or earlier, transition them to TLS 1.2 or later by 31 October 2024"

Where do I check which TLS-Version I use?

    Hi - Thanks for the question -

    If you're hosting using Azure service you would need to check this on a per resource basis. For many Az resources this is a simple as checking in the Azure portal (as one example, API Management has a protocols and ciphers page which clearly shows this type of info). That being said , I can check if there's a list of services that will deprecate older TLS versions.

    In addition , and this may be useful if you're hosting your own code , you can also check from the outside in if you have external endpoints (for example an external website you're hosting) using tools like SSL Labs which will give you a full report including cipher suites used

    The notification carried some more detail on what's happening here
