Support for Enterprise web apps

Web apps delivery using the Citrix Gateway service enables enterprise specific applications to be delivered remotely as a web-based service. Commonly used web apps include SharePoint, Confluence, OneBug, and so on.

Web apps can be accessed using Citrix Workspace using the Citrix Gateway service. The Citrix Gateway service coupled with Citrix Workspace provides a unified user experience for the configured Web apps, SaaS apps, configured virtual apps, or any other workspace resources.

SSO and remote access to web apps are available as part of the following service packages:

  • Gateway Service Standard
  • Workspace Standard, Workspace Premium, or Workspace Premium Plus

System requirements

Citrix Gateway Connector – A virtual appliance that facilitates the remote access to the Enterprise web apps. Citrix Gateway Connector is a virtual appliance. The virtual machine specification must at least have:

  • Number of vCPUs must be exactly 2.
  • 4 GB RAM minimum.
  • 1 Network Adapter (virtual NIC). You can add an extra virtual NIC upon requirement.

Install the Gateway Connector before configuring the Enterprise web apps for a cleaner approach.

Important: If there are SSL intercepting devices in the on-premises data center where the Citrix Gateway Connector must be deployed, the connector registration does not succeed if SSL interception is enabled for these FQDNs. The SSL interception must be disabled for these FQDNs for successful connector registration. For more information on Citrix Gateway Connector, see Citrix CloudGateway Connector.

How it works

Citrix Gateway service securely connects to the on-premises data center using Citrix CloudGateway Connector, which is deployed on-premises. This connector acts as a bridge between Enterprise web apps deployed on-premises and the Citrix Gateway service. These connectors can be deployed in an HA pair and require only an outbound connection.

A TLS connection between the Gateway connector and the Citrix Gateway service in the cloud secures the on-premises applications that are enumerated into the cloud service. Web applications are accessed and delivered through Workspace using a VPN-less connection. The following figure illustrates accessing web applications using Citrix Workspace.

How web apps work

Ways to configure Enterprise web apps

Enterprise web apps can be configured and published in the following two ways:

Configure and publish Enterprise web apps manually

The following configuration takes the SharePoint app as an example to configure and publish an app manually:

  1. On the Citrix Gateway service tile, click Manage.

  2. Click Add a Web/SaaS App tab below the Single Sign On tile.

  3. Click Skip to configure the SharePoint app manually.

    Skip adding template

  4. Check Inside my corporate network radio button.

    Enter the following details in the App Details section and click Next.

    Name – Name of the application that you are adding.

    URL – URL with your customer ID. The URL must contain your customer ID (Citrix Cloud customer ID). To get your customer ID, see Sign up for Citrix Cloud. In case SSO fails or you do not want to use SSO, the user is redirected to this URL.

    Customer domain name and Customer domain ID - Customer domain name and ID are used to create the app URL and other subsequent URLs in the SAML SSO page.

    For example, if you are adding a Salesforce app, your domain name is salesforceformyorg and ID is 123754, then the app URL is https://salesforceformyorg.my.salesforce.com/?so=123754.

    Customer domain name and Customer ID fields are specific to certain apps.

    Related Domains – The related domain is auto-populated based on the URL that you have provided. Related domain helps the service to identify the URL as part of the app and route traffic accordingly. You can add more than one related domain.

    Icon – Click Change icon to change the app icon. The icon file size must be 128x128 pixels. If you do not change the icon, the default icon is displayed.

    Description – This description that you enter here is displayed to your users in the workspace.

  5. In the Enhanced Security section, select Enable enhanced security to choose the security options you would like to apply to the application.

    Important: The Enhanced Security section is available only if you are entitled to Access Control service. For details, see https://www.citrix.com/products/citrix-cloud/.

    The following enhanced security options can be enabled for the application.

    • Restrict clipboard access: Disables cut/copy/paste operations between the app and system clipboard
    • Restrict printing: Disables ability to print from within the Citrix Workspace app browser
    • Restrict navigation: Disables the next/back app browser buttons
    • Restrict downloads: Disables the user’s ability to download from within the app
    • Display watermark: Displays a watermark on the user’s screen displaying the user name and IP address of the user’s machine

    Enhanced security

    The following advanced app protection policies can be enabled for the application.

    Restrict keylogging: Protects against key loggers. When a user tries to log on to the app using the user name and password, all the keys are encrypted on the key loggers. Also, all activities that a user performs on the app are protected against key logging. For example, if app protection policies are enabled for Office365 and the user edit an Office365 word document, all key strokes are encrypted on key loggers.

    Restrict screen capture: Disables the ability to capture the screens using any of the screen capture programs or apps. If a user tries to capture the screen, a blank screen is captured.

    Important:

    • You can enable these policies only after enabling the Enable enhanced security option.
    • These policies are enabled per app because not all apps might require these restrictions.
    • The app protection policies work only when the app is delivered through the Citrix embedded browser.

    Select Enforce policy on mobile device to enable the previously mentioned enhanced security options on your mobile device.

  6. Now you must connect to a resource location. You can either select an existing resource location or create one. To choose an existing resource location, click one of the resource locations from the list of resource locations, for example My Resource Location, and click Next. For guidance on adding a resource location, click https://docs.citrix.com/en-us/citrix-gateway-service/gateway-connector.html

    Add new resource location

  7. Select your preferred single sign-on type to be used for your application and click Save. The following single sign-on types are available.

    Save config

    • Basic – If your back-end server presents you with a basic-401 challenge, choose Basic SSO. You do not need to provide any configuration details for the Basic SSO type.
    • Kerberos – If your back-end server presents you with the negotiate-401 challenge, choose Kerberos. You do not need to provide any configuration details for the Kerberos SSO type.
    • Form-Based – If your back-end server presents you with an HTML form for authentication, choose Form-Based. Enter the configuration details for the Form-Based SSO type.
    • SAML - Choose SAML for SAML-based SSO into web applications. Enter the configuration details for SAML SSO type.

    • Assertion URL – Assertion URL is provided by the application vendor. The SAML assertion is sent to this URL.
    • Relay State – The Relay State parameter is used to identify the specific resource the users access after they are signed in and directed to the relying party’s federation server. Relay State generates a single URL for the users. Users can click this URL to log on to the target application.
