Amazon CloudFront now supports TLS 1.3 when connecting to your origins, providing enhanced security and improved performance for origin communications. This upgrade offers stronger encryption algorithms, reduced handshake latency, and better overall security posture for data transmission between CloudFront edge locations and your origin servers. TLS 1.3 support is automatically enabled for all origin types, including custom origins, Amazon S3, and Application Load Balancers, with no configuration changes required on your part.
TLS 1.3 provides faster connection establishment through a reduced number of round trips during the handshake process, delivering up to 30% improvement in connection performance when your origin supports it. CloudFront will automatically negotiate TLS 1.3 when your origin supports it, while maintaining backward compatibility with lower TLS versions for origins that haven’t yet upgraded. This enhancement benefits applications requiring high security standards, such as financial services, healthcare, and e-commerce platforms that handle sensitive data.
TLS 1.3 support for origin connections is available at no additional charge in all CloudFront edge locations. To learn more about CloudFront origin TLS, see the Amazon CloudFront Developer Guide.
