# Entri Secure Overview

> Automated SSL provisioning — what Entri Secure is and when to use it.

<Note>
  Entri Secure's REST endpoints (`/ssl/*`) are served by the **Connect API gateway** at `https://api.goentri.com`, not by a separate Secure host. Under the hood, Secure runs on an SNS → SQS → Lambda pipeline and does not expose its own public API.
</Note>

Entri has the ability to automatically provision SSL certificates. Your happy customers will be able to secure custom encrypted domains for your application instantly with no extra work required by your engineering team.

## About Entri Secure SSL certificates (FAQ)

### How does Entri Secure's SSL configuration work?

Entri uses a reverse proxy with SSL termination. To illustrate the flow of data:

1. A client (such as a web browser) makes a request to your customer's domain.
2. That request goes through Entri's reverse proxy server and is passed along to your service.
3. Your service returns a response through the reverse proxy, which is then passed back to the client.

### Why should you trust Entri Secure as a reverse proxy?

Entri Secure uses Amazon Web Services with [multi-region architecture](https://aws.amazon.com/solutions/implementations/multi-region-application-architecture/) to avoid single points of failure and minimize latency. We also leverage advanced distributed denial of service (DDOS) protection.
