System requirements
While waiting for Citrix to provision Citrix Endpoint Management, be sure to prepare for your Citrix Endpoint Management deployment by installing Cloud Connector. Although Citrix hosts and delivers your Citrix Endpoint Management solution, some communication and port setup is required. That setup connects the Citrix Endpoint Management infrastructure to corporate services, such as Active Directory.
Cloud Connector requirements
Citrix uses Cloud Connector to integrate the Citrix Endpoint Management architecture into your existing infrastructure. Cloud Connector integrates the following resource locations to Citrix Endpoint Management securely over port 443: LDAP, PKI Server, internal DNS queries, and Citrix Workspace enumeration.
-
At least two dedicated Windows Server machines that are joined to your Active Directory domain. The machines can be virtual or physical. The machine where you’re installing the Connector must be in sync with UTC time for proper installation and operation. For a full list of the latest requirements, see the deployment materials provided by your Citrix Account team.
The onboarding wizard guides you through installing Cloud Connector on those machines.
-
For more platform system requirements, see Citrix Cloud Connector.
Supported Active Directory functional levels
For use with Citrix Endpoint Management, the Citrix Cloud Connector supports the following forest and domain functional levels in the Active Directory.
| Forest Functional Level | Domain Functional Level | Supported Domain Controllers |
|---|---|---|
| Windows Server 2016 | Windows Server 2016 | Windows Server 2016, Windows Server 2019 |
| Windows Server 2016 | Windows Server 2019 | Windows Server 2019 |
| Windows Server 2019 | Windows Server 2019 | Windows Server 2019 |
Note:
Windows Servers 2012 R2, 2012, and 2008 R2 are no longer supported as they have reached end of life. For more information, see Microsoft products life cycle documentation.
NetScaler Gateway requirements
Citrix Endpoint Management requires a NetScaler Gateway installed in your resource location for the following scenarios:
- You require a micro VPN for access to internal network resources for line-of-business apps. Those apps are wrapped with Citrix MDX technology. The micro VPN needs NetScaler Gateway to connect to internal back-end infrastructures.
- You plan to use Citrix mobile productivity apps, such as Citrix Secure Mail.
- You plan to integrate Citrix Endpoint Management with Microsoft Endpoint Manager.
The requirements:
- Domain (LDAP) authentication
- NetScaler Gateway 12.1 or above, with a Platform/Universal license
For details, see Licensing.
- Public SSL Certificate.
For details, see Create and Use SSL Certificates on a Citrix ADC Appliance.
- Unused public IP address for NetScaler Gateway Virtual Server
- Publicly resolvable Fully Qualified Domain Name (FQDN) for NetScaler Gateway Virtual Server
- Cloud-hosted Citrix Endpoint Management Intermediate and Root certificates (provided in the script bundle)
- Unused internal private IP address for the proxy load balancer IP
- For port requirements, see NetScaler Gateway port requirements later in this article.
- Citrix Endpoint Management integration with Microsoft Endpoint Manager
- Deploy Citrix ADC VPX instance on Microsoft Azure
For information about NetScaler Gateway requirements, see the deployment materials provided by your Citrix Account team.
For information about Android Enterprise requirements, see the Android Enterprise section.

Port requirement for AutoDiscovery service connectivity
This port configuration makes sure that Android devices connecting from Citrix Secure Hub for Android can access the Citrix Endpoint Management AutoDiscovery service (ADS) from within the internal network. The ability to access the ADS is important when downloading any security updates made available through the ADS.
Note:
ADS connections might not support your proxy server. In this scenario, allow the ADS connection to bypass the proxy server.
If you want to enable certificate pinning, complete the following prerequisites:
- Collect Citrix Endpoint Management server and NetScaler Gateway certificates: The certificates must be in PEM format and must be a public certificate and not the private key.
- Contact Citrix Support and place a request to enable certificate pinning: During this process, you’re asked for your certificates.
Certificate pinning requires that devices connect to ADS before the device enrolls. This requirement makes sure that the latest security information is available to Citrix Secure Hub. For Citrix Secure Hub to enroll a device, the device must reach the ADS. So opening ADS access within the internal network is critical to enabling devices to enroll.
To allow access to the ADS for Citrix Secure Hub for Android/iOS, open port 443 for the following FQDN :
| FQDN | Port | IP and port usage |
|---|---|---|
discovery.cem.cloud.us |
443 | Citrix Secure Hub - ADS Communication via CloudFront |
For information on supported IP addresses, see Cloud-based storage centers from AWS.
Android Enterprise network requirements
For information about the outbound connections to consider when setting up network environments for Android Enterprise, see the Google support article, Android Enterprise Network Requirements.
App requirements
Citrix Endpoint Management supports adding and maintaining up to 300 apps. Going over this limit causes your system to become unstable.
