Object Storage Supports Bucket Level Encryption
- Services: Object Storage
- Release Date: June 30, 2026
Bucket level encryption can now be enabled for buckets in Object Storage.
For more information, see Updating an Object Storage Bucket to Use an SSE-KMS Bucket Key.
When using customer managed Vault (KMS) keys, Object Storage data can now be encrypted at the bucket level. Bucket level encryption uses a bucket-scoped intermediate encryption key protected by the customer's KMS key. We recommend enabling the Bucket Key encryption setting when using a customer managed Vault (SSE-KMS) key for encryption to reduce calls from Object Storage to KMS, which lowers PUT and GET latency, and decreases the likelihood of KMS throttling.
