MFT vs SFTP: what's the difference, and which do you need?
A plain-English comparison of SFTP and managed file transfer for small and mid-size IT teams, with a quick table, decision checklist and FAQ.
Short answer: SFTP is a protocol that moves a file securely from one system to another over SSH. Managed file transfer (MFT) is a platform that automates, monitors and audits file transfers, and usually uses SFTP (and other protocols) underneath. If you transfer a few files now and then, SFTP is often enough. If transfers are recurring, business-critical or need proof for auditors, you need MFT.
What is SFTP?
SFTP (SSH File Transfer Protocol) moves files over an encrypted SSH connection, with password or key-based authentication. It is free, built into OpenSSH on almost every Linux server, and supported by clients like WinSCP and FileZilla. What it does not do on its own: schedule transfers, retry failed ones, alert anyone, or keep a business-level record of who sent what and when. Teams usually add that with scripts and cron jobs.
What is managed file transfer (MFT)?
Managed file transfer is software that manages the whole file exchange process: automated and scheduled or event-driven transfers, retries, integrity checks, alerts on failure, central monitoring, access control and an audit trail. IBM describes MFT as a higher-level system used to manage, monitor and automate file exchanges, while SFTP is the network protocol that moves the files.[1] In many organisations MFT builds on SFTP rather than replacing it.[2]
MFT vs SFTP at a glance
| SFTP | Managed file transfer (MFT) | |
|---|---|---|
| What it is | A secure transfer protocol | A platform that runs and governs transfers |
| Encryption in transit | Yes (SSH) | Yes, via SFTP, FTPS, HTTPS or similar |
| Automation & scheduling | Only with your own scripts | Built in |
| Retries & integrity checks | Only with your own scripts | Built in |
| Monitoring & alerts | No | Central dashboard and notifications |
| Audit trail | Server logs only | Searchable transfer history for audits |
| Typical cost | Free (OpenSSH) or low-cost servers | From a few hundred to tens of thousands per year |
| Best for | Occasional transfers between trusted systems | Recurring, business-critical or regulated transfers |
Costs vary widely. Couchdrop, a vendor that sells both, writes that MFT can cost several times more than an SFTP server, sometimes 50 times or more.[3]
When SFTP is enough
- You move a handful of files occasionally, and a person checks that they arrived.
- There is one partner or one system on each side, and nobody asks for reports.
- A missed or failed transfer is noticed quickly and is cheap to redo.
When you need managed file transfer
- Transfers run every day between branches, partners, ERP exports or other business systems.
- A silent failure costs money: missing orders, late invoices, unhappy customers.
- You must show auditors or customers what was transferred, when and to whom (GDPR, ISO 27001).
- Your team is maintaining a growing pile of transfer scripts. As JSCAPE puts it, if you are writing scripts to patch gaps for logging, notifications and escalation, you are doing MFT work without the platform.[4]
The middle ground for small teams
Enterprise MFT suites are built for large partner networks and many protocols, and are priced accordingly. Many small and mid-size businesses only need the core: automatic transfers from folders to a central server they control, integrity checks, and a dashboard that tells them when something stops working. That is the gap Emona MFT is designed for.
To be precise about the current state: Emona MFT is in development and is built on the source-available jFiltra core, which uses its own client-server transfer protocol rather than SFTP. The jFiltra core does not encrypt the connection, so run it inside a VPN, an SSH tunnel or a trusted network. Emona MFT adds protocol 2, which authenticates both sides and encrypts file names and content with AES-256-GCM; TLS itself is not used. See Security and roadmap for details.
Frequently asked questions
Is SFTP the same as FTPS?
No. SFTP runs over SSH, usually on port 22. FTPS is classic FTP wrapped in TLS, the same encryption used by HTTPS. Both encrypt data in transit, but they are different protocols and need different servers and firewall rules.
Does managed file transfer replace SFTP?
Usually not. Most MFT platforms use SFTP as one of their transfer protocols and add automation, monitoring, alerts and an audit trail on top of it.
Is managed file transfer only for large enterprises?
No. Any business with recurring, business-critical file transfers can benefit. The difference is scale: small teams usually need automation, monitoring and an audit trail, not dozens of protocols and partner portals, so a lighter, self-hosted MFT tool is often the better fit.
Is plain FTP still acceptable?
Not for business data. Plain FTP sends files and passwords unencrypted. Use SFTP or FTPS at minimum, or an MFT platform that encrypts transfers.
