What SFTP.cloud is

SFTP.cloud is a managed file transfer service. It gives your organization a transfer server on the internet, with its own address, its own user accounts and its own certificates, without you running that server.

The part that is unusual: the service never stores your files. Your files stay on storage you already own, in your own data center or in your own cloud account. A small piece of software called the Storage Connector sits next to that storage and links it to your transfer server.

What you get

• An address such as acme.on.sftp.cloud, or bring your own domain such as files.yourcompany.com.
• Four ways for people to connect: SFTP, FTPS, FTPES and a web client in the browser.
• User accounts you create and control, each one restricted to the folders you choose.
• Certificates issued and renewed automatically, with nothing for you to install or remember to keep them current.
• A digitally signed, tamper-evident record of every file operation, independently verifiable (without needing our help to do so).

What you bring

• Storage. A disk, a NAS, an S3 bucket, an Azure container, a Google Cloud bucket, or another SFTP server. See Storage backends.
• A machine or a container to run the Storage Connector. Any Windows or Linux machine, or Docker container, that can reach your storage and can make outbound HTTPS connections. It does not need a public IP address, an open firewall port, or a DNS name.

What it costs you in setup time

About an hour, once, following Your first hour. Most of that hour is waiting for a download and typing a few names.

The three pieces

Piece	Where it runs	What it does
Portal	Run by Syncplify	Your account, your sites, your plan, your users, your billing
Head	Run by Syncplify	The transfer server itself: it answers SFTP, FTPS and HTTPS and checks who is signing in
Connector	Run by you	Sits next to your storage, holds your permissions, performs the actual reads and writes

The Portal and the Head are ours to run and keep alive. The Connector is yours.

How the pieces fit together explains what happens between them when somebody signs in and downloads a file.

What you will not find

• No file storage on our side. There is no bucket of yours on our infrastructure to leak.
• No inbound firewall rule. The Connector dials out. Nothing ever dials in to it.
• No port numbers to choose. Your site answers on the standard ports: 22, 21, 990 and 443. See Protocols and ports.
• No certificate management. Certificates are issued and renewed for you.

This service is in alpha
