I explain external key management for Tableau extracts, which is fundamentally about encryption. By providing Tableau Cloud with an encryption key you control via AWS KMS, you ensure that even someone with direct server access can't open your extract files without that external key.

## Key takeaways

- Encrypting an extract secures the file so that direct access to the server doesn't allow opening it in Tableau Desktop without the key
- With external key management, you supply and control your own encryption key rather than relying solely on Tableau's
- Tableau Cloud integrates directly with AWS Key Management Service (KMS) to give you full control over the keys protecting your data
- Cycling or changing keys in AWS syncs with Tableau Cloud, and extracts may need to be regenerated to use the new key
- External key management for extracts is generally available in Tableau Cloud
