# Compliance validation for Amazon OpenSearch Service
<a name="compliance-validation"></a>

Third-party auditors assess the security and compliance of Amazon OpenSearch Service as part of multiple Amazon compliance programs. These programs include SOC, PCI, and HIPAA.

If you have compliance requirements, consider using any version of OpenSearch or Elasticsearch 6.0 or later. Earlier versions of Elasticsearch don't offer a combination of [encryption of data at rest](encryption-at-rest.md) and [node-to-node encryption](ntn.md) and are unlikely to meet your needs. You might also consider using any version of OpenSearch or Elasticsearch 6.7 or later if [fine-grained access control](fgac.md) is important to your use case. Regardless, choosing a particular OpenSearch or Elasticsearch version when you create a domain does not guarantee compliance. 

To learn whether an Amazon Web Services service is within the scope of specific compliance programs, see [Amazon Web Services services in Scope by Compliance Program](https://aws.amazon.com/compliance/services-in-scope/) and choose the compliance program that you are interested in.
