What is the AWS KMS eXternal Key Store (XKS) service?

AWS announced eXternal Key Store (XKS) support for its Key Management Service (KMS) at the AWS re:Invent conference in November 2022. XKS enables next-level control and ownership of keys for a growing range of AWS services that use KMS. With XKS, AWS users can externally generate, host, and manage Root Keys for data encryption keys that are used in AWS KMS.

Fortanix Data Security Manager (DSM) integration with AWS XKS enables organizations to protect the data in AWS with keys stored in Fortanix DSM. With this capability, Fortanix customers can now migrate privacy-sensitive workloads for highly regulated industries such as financial services and healthcare, to the public cloud and comply with the highest data privacy regulations.
