Note

Requires [Cloudflare Browser Isolation](https://developers.cloudflare.com/cloudflare-one/remote-browser-isolation/).

With Access policies, you can require users to open self-hosted applications in a secure [remote browser](https://developers.cloudflare.com/cloudflare-one/remote-browser-isolation/). Because the remote browser is directly integrated into our Secure Web Gateway platform, [HTTP policies](https://developers.cloudflare.com/cloudflare-one/traffic-policies/http-policies/) can be applied to isolated applications without needing to install the WARP client. This allows you to distribute internal applications to unmanaged users while retaining control over sensitive data.

## Prerequisites

Your browser must [allow third-party cookies](https://developers.cloudflare.com/cloudflare-one/access-controls/applications/http-apps/authorization-cookie/#allow-third-party-cookies-in-the-browser) on the application domain.

## Enable Browser Isolation

1. In [Cloudflare One](https://one.dash.cloudflare.com/), go to **Browser isolation** > **Browser isolation settings**.
2. Under **Manage remote browser permissions**, select **Manage**.
3. Enable **Clientless Web Isolation**.

1) Go to **Access controls** > **Applications**.
2) Choose a [self-hosted application](https://developers.cloudflare.com/cloudflare-one/access-controls/applications/http-apps/self-hosted-public-app/) and select **Configure**.
3) Go to **Policies**.
4) Choose an [Allow policy](https://developers.cloudflare.com/cloudflare-one/access-controls/policies/) and select **Configure**.
5) Under **Additional settings**, turn on **Isolate application**.
6) Save the policy.

Browser Isolation is now enabled for users who match this policy. After the user logs into Access, the application will launch in a remote browser. To confirm that the application is isolated, refer to [Check if a web page is isolated](https://developers.cloudflare.com/cloudflare-one/remote-browser-isolation/setup/#3-check-if-a-web-page-is-isolated).

You can optionally add another Allow policy for users on managed devices who do not require isolation.

## Policies for isolated applications

Traffic to the isolated Access application is filtered by your Gateway [HTTP policies](https://developers.cloudflare.com/cloudflare-one/traffic-policies/http-policies/). Useful policies include:

* [Identity-based policies](https://developers.cloudflare.com/cloudflare-one/traffic-policies/identity-selectors/) to allow or block requests based on user identity.
* [Data Loss Prevention policies](https://developers.cloudflare.com/cloudflare-one/data-loss-prevention/) to log or block transmission of sensitive data.
* [Isolation policies](https://developers.cloudflare.com/cloudflare-one/remote-browser-isolation/isolation-policies/) to disable browser actions such as copy/paste, printing, or file downloads.

For example, if your application is hosted on `internal.site.com`, the following policy blocks users from uploading and downloading credit card numbers within the remote browser:

| Selector | Operator | Value | Logic | Action |
| - | - | - | - | - |
| Domain | in | `internal.site.com` | And | Block |
| DLP Profile | in | `Financial Information` | | |

## Product compatibility
