What does the Amazon OpenSearch Service BAA cover?
The AWS BAA covers the use and disclosure of protected health information (PHI) within HIPAA‑eligible services, including Amazon OpenSearch Service.

Their BAA covers:
- Protection of PHI through encryption and secure hosting

- Audit trails and logging for PHI access
- Return or destruction of PHI upon termination

- Configuring encryption at rest and node‑to‑node encryption.
- Implementing fine‑grained access controls.
- Following AWS’s shared responsibility model (AWS secures infrastructure, customers secure configurations).
Conclusion
Amazon OpenSearch Service signs a BAA and is therefore HIPAA compliant.
