NetScaler Gateway VPN clients and supported features
Important:
Citrix SSO for iOS/Android is now called Citrix Secure Access. We are updating our documentation and the UI screenshots to reflect this name change.
The legacy VPN client was built using Apple’s private VPN APIs that are now deprecated. VPN support in Citrix Secure Access client for macOS/iOS is rewritten using Apple’s public Network Extension framework. NetScaler Gateway plug-in and VPN for iOS and macOS are no longer supported. Citrix Secure Access for iOS/macOS is the recommended VPN client to be used.
General availability of nFactor authentication support for Android devices would be available in one of the upcoming releases.
The following table lists some of the commonly used features supported for each VPN client.
