If you use Amazon Virtual Private Cloud (Amazon VPC) to host your AWS resources, you can establish a private connection between your VPC and AWS CloudTrail. You can use this connection to enable CloudTrail to communicate with your resources on your VPC without going through the public internet.
Amazon VPC is an AWS service that you can use to launch AWS resources in a virtual network that you define. With a VPC, you have control over your network settings, such the IP address range, subnets, route tables, and network gateways. With VPC endpoints, the routing between the VPC and AWS services is handled by the AWS network, and you can use IAM policies to control access to service resources.
To connect your VPC to CloudTrail, you define an interface VPC endpoint for CloudTrail. An interface endpoint is an elastic network interface with a private IP address that serves as an entry point for traffic destined to a supported AWS service. The endpoint provides reliable, scalable connectivity to CloudTrail without requiring an internet gateway, network address translation (NAT) instance, or VPN connection. For more information, see What is Amazon VPC in the Amazon VPC User Guide.
Interface VPC endpoints are powered by AWS PrivateLink, an AWS technology that
enables private communication between AWS services using an elastic network interface with
private IP addresses. For more information, see AWS PrivateLink
The following steps are for users of Amazon VPC. For more information, see Get started with Amazon VPC in the Amazon VPC User Guide.

Create a VPC endpoint for CloudTrail
To start using CloudTrail with your VPC, create an interface VPC endpoint for CloudTrail. For more information, see Access an AWS service using an interface VPC endpoint in the Amazon VPC User Guide.
You don't need to change the settings for CloudTrail. CloudTrail calls other AWS services using either public endpoints or private interface VPC endpoints, whichever are in use.
Shared subnets
A CloudTrail VPC endpoint, like any other VPC endpoint, can only be created by an owner account in the shared subnet. However, a participant account can use CloudTrail VPC endpoints in subnets that are shared with the participant account. For more information about Amazon VPC sharing, see Share your VPC with other accounts in the Amazon VPC User Guide.
