Today we are updating the minimum supported TLS version to 1.2 on Amazon ElastiCache compatible with open-source Redis version 6 and above, across all regions. This update is designed to help you meet security, compliance, and regulatory requirements.
Amazon ElastiCache supports the Transport Layer Security (TLS) encryption protocol, which is used to secure data in-transit over the network. TLS versions 1.0 and 1.1 are no longer recommended as a security best practice, and we have historically supported them to maintain backward compatibility for customers that have older or difficult to update clients. ElastiCache will continue to support TLS 1.0 and 1.1 until May 8, 2025, and customers must update their client software before that date. For more information about ElastiCache and in-transit encryption (TLS), see our documentation.
