Uploading Data to the Horizon FTPS Server
In order to upload or download data to or from Horizon's FTPS server, Horizon customers will need to use an FTP client and authenticate using a secure account. FileZilla is a free multi-platform FTP client which can be installed and configured quickly and easily. This article will detail the process to download and install FileZilla and configure the Horizon FTPS server for customer access. Other FTP clients can be used provided they support FTP over TLS with explicit encryption.
Your Horizon FTPS credentials can be provided by your Horizon project manager. If you do not have them or they aren't working, please contact your Horizon project manager.
Procedure
- Download the FileZilla client.
- Run the FileZilla client installer, accepting defaults in the wizard. Decline any optional offers during installation, such as AVG Secure Browser.
- Run FileZilla and click the Hosts button on the toolbar:
- Click the New site button:

- Enter the following information:
- Click the Connect button, choose the Save passwords option, and click the OK button.
- If an Unknown certificate window appears, confirm the SSL certificate lists "ftps.horizon-is.com" in the common/alternative names, check both boxes at the bottom of the window to trust the certificate, then click the OK button.
- FileZilla should make a secure connection to the Horizon FTPS server and place you in the customer's secure directory.
- You can now drag-and-drop files between the local machine and the Horizon FTPS server as needed.
