Secure Browser service

The Citrix Secure Browser service isolates web browsing to protect the corporate network from browser-based attacks. It delivers consistent, secure remote access to internet hosted web applications, with no need for user device configuration. Administrators can rapidly roll out secure browsers, providing instant time-to-value. By isolating internet browsing, IT administrators can offer end users safe internet access without compromising enterprise security.

Users log on through Citrix Workspace (or Citrix Receiver) and can open web apps in the configured web browser. The website does not directly transfer any browsing data to or from the user device, so the experience is secure.

The Secure Browser service can publish secure browsers for use with:

  • Unauthenticated external web apps. Although typically not recommended, unauthenticated external web apps might be used for a simple proof of concept.
  • Authenticated external web apps. Publishing authenticated external web apps requires a resource location containing at least one Cloud Connector (two or more are recommended). For details, see Citrix Cloud Connector.

The service also offers:

Integration with Citrix Workspace

Secure Browser can be integrated with Citrix Workspace. To ensure that it’s integrated:

  1. Sign in to Citrix Cloud.
  2. In the upper left menu, select Workspace Configuration.
  3. Select the Service Integrations tab.
  4. The Secure Browser service entry should indicate Enabled. If it does not, click the ellipsis menu and select Enable.

By default, all unauthenticated apps are available to all Workspace users without user assignment. For authenticated apps, you must explicitly add users with Citrix Cloud Library.

You can authenticate using Active Directory or Azure Active Directory. If you choose Azure Active Directory, the on-premises domain containing your Active Directory Domain Controllers must contain one (preferably two) Cloud Connectors. For more information, see:

Integrate with your on-premises StoreFront

Citrix Virtual Apps and Desktops customers with an on-premises StoreFront can easily integrate with the Secure Browser Service to provide the following benefits:

  • Aggregate your published secure browsers with your existing Citrix Virtual Apps and Desktops apps for a unified store experience.
  • Use native Citrix Receivers for enhanced end user experience.
  • Strengthen security for Secure Browser launches by using your existing multifactor authentication solution integrated with your StoreFront.

For details, see CTX230272 and the StoreFront configuration documentation.

  3. Select the type of secure browser to publish: external unauthenticated (default) or external authenticated. Then click Continue.

    Select browser type screen

  4. Enter the name, start URL, and select the region. By default, the icon of the Google Chrome executable is used when you publish a Secure Browser. You can now bring your own icon to represent a published browser.

Time-outs

Timeouts console

Time-out settings include:

  • Idle Timeout: The number of minutes a session can remain idle before it is ended due to inactivity.
  • Idle Warning Time: The number of minutes before ending a session that a warning message is sent to the user.

For example, if you set an idle timeout of 20 and an idle warning time of 5, a message will be sent to the user if there is no activity in the session for 15 minutes (20 minus 5). If the user does not respond, the session will end five minutes later.

When you’re done, click OK.

Policies

Policies console

Settings on the policies page control the following:

  • Clipboard: Disabling the clipboard prevents copy and paste operations to and from the remote session. (The Clipboard button is removed from the Citrix Workspace app toolbar.) By default, this setting is disabled.
  • Printing: When you enable printing, the remote webpage can be saved as a PDF and transferred to the user’s device. The user can then press Ctrl-P and select the Citrix PDF printer. By default, this setting is disabled.
  • Non-kiosk: Enabling non-kiosk mode restores the interface to the remote browser. The user can then access the address bar and create multiple tabs and windows. (Disabling non-kiosk mode removes the remote browser’s navigation controls and address bar.) By default, this setting is enabled (non-kiosk mode is on).
  • Client drive mapping: Enabling the client drive mapping policy allows the user to upload and download files to and from the remote session. This feature is available only for sessions launched with the Citrix Workspace app. By default, this policy is disabled.
    • Users must save downloaded files only on the ctxmnt disk in the Anonxxx directory. To do that, users need to navigate to the desired location for storing the file. For example, Anonxxx > ctxmnt > C > Users > User Name > Documents.

      Anonxxx directory

    • The dialog box might prompt the user to accept the Permit all access or Read and Write permissions to access the ctxmnt folder.

      ctxmnt permissions

When you’re done, click OK.

Whitelists

Whitelists console

Use the Whitelists task to restrict users to visiting only whitelisted URLs within their published Secure Browser session. This feature is available for external authenticated web apps.

Enter whitelist entries in the form hostname:port number. Specify each entry on a new line. Asterisks are supported as wildcards. Browser requests must match at least one entry in the whitelist.

For example, to set https://example.com as a whitelisted URL:

  • example.com:* allows connection to this URL from any port.
  • example.com:80 allows connection to this URL only from port 80.
  • *:* allows access to this URL from any port and from any links to other URLs and ports. The *.* format allows access to all external web apps from the published app. This format is the default setting for the external web apps URL whitelist field.

When you’re done, click OK.

Advanced web filtering capabilities are available through integration with the Access Control service. Learn more at Use case: Selective access to apps.

Edit

Use the Edit task to change the name, start URL, or region of a published browser. When you’re done, click Publish.

Delete

Use the Delete task to remove a published secure browser. When you select this task, you’re prompted to confirm the deletion.

Monitor usage

Usage console

The Usage tab shows the:

Technical security overview

Secure Browser Service is a SaaS product managed and operated by Citrix. It allows access to web applications via an intermediate web browser hosted in the cloud.

Cloud service

The Citrix Secure Browser service consists of web browsers running on Virtual Delivery Agents (VDAs) along with the management console used to manage and connect users to these VDAs. Citrix Cloud manages the operation of these components, including the security and patching of operating systems, web browsers, and Citrix components.

While using Secure Browser service, hosted web browsers may track user’s browsing history and perform caching of HTTP requests. Citrix uses mandatory profiles and ensures that this data is deleted when the browsing session ends.

Secure Browser service is accessed with an HTML5-compatible web browser. The service does not provide any downloadable clients. All traffic between the browser being used and cloud service is encrypted using industry-standard TLS encryption. Secure Browser supports TLS 1.2 only.

Web applications

Citrix Secure Browser service is used to deliver web applications owned by the customer or a third party. The owner of the web application is responsible for its security, including patching the web server and application against vulnerabilities.

Security of the traffic between Secure Browser and the web application depends on the encryption settings of the web server. To protect this traffic as it flows over the Internet, administrators should publish HTTPS URLs.
