Support for TLS 1.0/1.1 on Azure Cache for Redis ending on 31 October 2024

Published date: October 06, 2023

Azure Cache for Redis will be retiring support for TLS versions 1.0 and 1.1 on 31 October, 2024. TLS versions 1.0 and 1.1 are known to be susceptible to various security attacks and there is an industry wide push towards enforcing TLS 1.2 for secure communication. Azure Cache for Redis will start enforcing TLS 1.2 for all connections starting November 1, 2024. 

Before 31 October 2024, please ensure that you take the following steps: 

  • Update your applications to connect using TLS 1.2.  

  • Update the Minimum TLS version on your cache instance to 1.2. 

Starting November 1, 2024, connections to Azure Cache for Redis instances which use TLS 1.0 or 1.1 will be blocked. Please refer to detailed instructions here to know how to ensure your applications are connecting to Redis instances using TLS 1.2.
