TLS 1.0 and 1.1 support will be removed for new & existing Azure storage accounts starting Nov 2024

To meet evolving technology and regulatory needs and align with security best practices, we are removing support for Transport Layer Security (TLS) 1.0 and 1.1 for both existing and new storage accounts in all clouds. TLS 1.2 will be the minimum supported TLS version for Azure Storage starting Nov 1, 2024.  


Azure Storage currently supports TLS 1.0 and 1.1 (for backward compatibility) and TLS 1.2 on public HTTPS endpoints. TLS 1.2 is more secure and faster than older TLS versions. TLS 1.0 and 1.1 do not support modern cryptographic algorithms and cipher suites. Many of the Azure storage customers are already using TLS 1.2 and we are sharing this guidance to expedite the transition for customers currently on TLS 1.0 and 1.1. Customers must secure their infrastructure by using TLS 1.2 with Azure Storage by Oct 31, 2024. The older TLS versions (1.0 and 1.1) are being deprecated and removed to meet evolving standards (FedRamp, NIST), and provide improved security for our customers 


This change will impact both existing and new storage accounts using TLS 1.0 and 1.1. To avoid disruptions to your applications connecting to Azure Storage, you must migrate to TLS 1.2 and remove dependencies on TLS version 1.0 and 1.1, by Oct 31, 2024.

As best practice, we also recommend using Azure policy to enforce a minimum TLS version. Learn more here about how to enforce a minimum TLS version for all incoming requests. If you already use Azure Policy to enforce TLS version, minimum supported version after this change rolls out will be TLS 1.2.
