We are excited to announce that Amazon OpenSearch Serverless is enhancing access controls for VPC endpoints. With this feature, administrators can attach endpoint policies to control which AWS principals are allowed or denied access to the OpenSearch resources through their VPC endpoint(s). With a VPC endpoint policy, users can also combine actions along with AWS principals and resources to have finer control on the allowing or denying the traffic through their VPC endpoint(s).

The support for VPC endpoint policy for OpenSearch Serverless is now available in 8 regions globally: US East (Ohio), US East (N. Virginia), US West (Oregon), Asia Pacific (Singapore), Asia Pacific (Sydney), Asia Pacific (Tokyo), Europe (Frankfurt), and Europe (Ireland). Please refer to the AWS Regional Services List for more information about Amazon OpenSearch Service availability. To learn more about OpenSearch Serverless, see the documentation.
