How it works

Secure Transfer Client - How it works

Secure Transfer Client is a software that is installed on the User Desktop in the Secure IT-system in either a sending or receiving variant. Files can be sent from and stored to any file storage the user can reach.

Sending a file is simple – drag it to the application windows and select a destination domain. The user’s smart card will be used for signing and encryption of the file prior to transmission. Receiving files is equally simple – once smart card authentication is done any received file will show up in the application as well as a taskbar notification.

Secure Transfer Client fully supports link22 Guard for transfer routing and policy enforcement.



Designed for ease of use with wizard style graphical user interface requiring minimal training. Drag-and-drop is supported. The Secure Transfer Client can be deployed either for sending or receiving.

Sending is done by drag-and-drop into the application windows and selecting a destination – in the example below RED.NET. Pressing Next will continue the transfer wizard.

Receiving a file is simple – a notification is shown and the file appears in the application window and is ready for download to local storage.
