About secure connections and certificates

Private (self-signed) certificates

When a private certificate is installed on the remote gateway, the root certificate for the organization’s certificate authority must be installed on the device to successfully access Citrix resources using Citrix Workspace app for iOS.


If the remote gateway’s certificate cannot be verified upon connection (because the root certificate is not included in the local keystore), an untrusted certificate warning appears. If a user chooses to continue through the warning, a list of applications is displayed; however, applications fail to start.

Trust manually installed certificate

In iOS 10.3 and later, a certificate included in a profile that you install manually is not automatically trusted for SSL. To trust manually installed certificate profiles in iOS:

  1. Make sure you have installed the certificate profile on the device.
  2. Go to Settings > General > About > Certificate Trust Settings.

    Each root that has been installed through a profile appears under Enable Full Trust For Root Certificates.

  3. You can toggle trust on or off for each root.

Import root certificates on iPad and iPhone devices

Obtain the root certificate of the certificate issuer and email it to an email account configured on your device. When clicking the attachment, you are asked to import the root certificate.

Wildcard certificates

Wildcard certificates are used in place of individual server certificates for any server within the same domain. Citrix Workspace app for iOS supports wildcard certificates.

Intermediate certificates and Citrix Gateway

When your certificate chain includes an intermediate certificate, the intermediate certificate must be appended to the Citrix Gateway (or Access Gateway) server certificate. Also, for Access Gateway installations, see the Knowledge Base article that matches your edition:

CTX114146: How to Install an Intermediate Certificate on Access Gateway Enterprise Edition

RSA SecurID authentication is supported for Secure Gateway configurations (through the Web Interface only) and all supported Access Gateway configurations.

Citrix Workspace app for iOS supports all authentication methods supported by Access Gateway.

Smart cards

Citrix Workspace app for iOS provides support for SITHS smart cards for in-session connections only.

If you are using FIPS Citrix Gateway devices, configure your systems to deny SSL renegotiations. For details, see How to configure the -denySSLReneg parameter.
