Introducing sftp.cloud (coming soon)
Your files stay yours. All of them. Always. Simply... SFTP-enabled.
For the better part of a decade, “cloud file transfer” has meant one thing in practice: move your files to someone else’s infrastructure, trust their encryption, and accept that somewhere in a data center you don’t control, a server you’ve never seen holds the keys to your data. Trust, trust, trust. In the age of zero trust you’re asked to trust the vendor with your most valuable data: your files.
We’ve never liked with that model. So we’ve built an alternative.
sftp.cloud is a managed SFTP, FTPS, FTPES, and HTTPS file transfer service, with a web client and full secure file sharing capabilities. But its architecture works differently from everything else in this space, in a few ways that matter.
Your files are never stored in our cloud. Not during transfers, not at rest, not ever. The cloud component is a protocol relay, not a storage destination. You deploy a lightweight connector on or next to your own storage servers, it opens an outbound connection to the cloud, and from that point forward your on-premises storage has a fully managed, highly available SFTP endpoint on the internet, without a single inbound firewall rule required on your end.
No NAT. No port forwarding. No DMZ gymnastics. Just an outbound connection from your side, and a professional-grade file transfer service facing the world.
The control plane follows the same principle. Your sftp.cloud configuration, your user credentials, your access policies, and - above all - your files: none of it lives in our cloud. Your control nodes connect outbound to the management layer, not the other way around. There is no “doorbell” on your on-prem nodes for anyone to ring, because there is no door. Not a locked one. Not a hidden one. The attack surface simply does not exist.
We’re calling this an inverted control plane. It’s the first time this architecture has been applied to a cloud SFTP SaaS, and we think once you see how it works, you’ll find it difficult to settle for anything less.
One thing worth saying clearly: sftp.cloud is not a replacement for Syncplify Server!, R2FS!, or AFT!. Those products aren't going anywhere, and neither is our commitment to them. sftp.cloud is an entirely new product, built for a different set of use cases, specifically the organizations that need a managed, internet-facing file transfer endpoint without the overhead of running and maintaining their own server infrastructure, yet refuse to surrender control of their data to do it.
More detail on the architecture, the connector deployment model, and everything else is coming soon. If you want to be among the first to know when sftp.cloud opens for early access, subscribe to this blog. We’ll post here first.
