# Quick start for IT

> Security overview, SSO configuration, and embedding the Circuit chat widget on your site.

This guide covers what IT teams need to know to evaluate, deploy, and integrate Circuit.

## Security at a glance

Circuit is designed with enterprise security in mind:

* **Authentication** via Google or Microsoft identity providers with SSO support
* **Data isolation**: each workspace's indexes are stored in a separate, isolated database
* **Encryption** in transit (TLS) and at rest
* **Role-based access control** at the workspace, index, and agent levels
* **API key scoping** with optional domain restrictions for embedded chat widgets

For a detailed breakdown, see the [security overview](/it/security).

## Embed the chat widget

The fastest way to add Circuit to your website is a single script tag. You'll need an API key from your Circuit agent.

```html theme={null}
<script src="https://build.app.circuit.ai/chat-widget/circuit-chat-widget.iife.js?apiKey=YOUR_AGENT_KEY"></script>
```

The widget appears as a chat button in the bottom-right corner of your page. It handles chat sessions, streaming responses, and citation rendering automatically.

<Note>
  The API key is agent-specific. Create one from the agent's settings in Circuit. You can restrict it to specific domains for security.
</Note>

For full setup details, see [embedding the chat widget](/it/embedding-chat-widget).
