## AI overview

Backblaze B2 will automatically apply server-side AES-256 encryption to newly uploaded and copied object data at rest. SSE-B2 requires no application changes, added cost, or performance tradeoff, while SSE-C remains available for objects encrypted with customer-provided keys.

## Source excerpt

Starting September 14, Backblaze B2 will automatically encrypt every new upload and destination copy at rest with AES-256. Always-on SSE-B2 strengthens security without application changes, added costs, or performance impact, while preserving SSE-C for customer-managed encryption keys when required instead.
