The two ways to do it

Azure Blob's SFTP endpoint, or Diplomat MFT as the platform around it

Same storage destination. Two very different ways to get files there and back, and to govern them once they move.

Azure Blob's SFTP endpoint

A direct SFTP connection into one Azure storage account. Right for a simple point-to-point handoff.

Lets trading partners connect to one Blob container over SFTP
Always-on charge, roughly $220 a month per storage account, whether or not you transfer anything
Local SFTP users only. No Entra ID or Azure AD
No browser upload for partners who do not run an SFTP client
No OpenPGP, no scheduling, no transfer-level audit trail
Sees that one storage account. Nothing routes onward to S3, on-premises or a partner
Diplomat MFT

Diplomat MFT

A managed transfer platform around Azure Blob and beyond.

An SFTP server your partners connect to, moving files both into Blob and back out
A browser-based Web Transfer Portal, no SFTP software required
Automated workflows that move files into and out of Blob
Built-in OpenPGP, auditing and alerts on every transfer
Easy SFTP user and key management in one place
Connect Azure Blob, S3, SharePoint and on-premises from one engine
Deploy on-premises, in your own data center, or in any cloud, and still front Azure Blob, with no need to run inside Azure itself

For this one job, the spend may be similar. The capability is not.

If all you need is a single SFTP door into one Azure Blob account, the native feature is a valid choice. Once the job becomes partner uploads, browser access, automated delivery, OpenPGP, user management, auditing or alerting, you are no longer buying an SFTP endpoint. You are choosing whether to buy a transfer platform around Azure Blob.

Azure's built-in SFTP endpoint

~$220/mo per account, always on

What it covers:

A single SFTP door into one Blob account
Encryption, scheduling, routing, alerting and the audit trail are still yours to build

Diplomat MFT

One platform around Azure Blob

What you also get:

Browser-based Web Transfer Portal, with OpenPGP built in
Edge Gateway for safe inbound, no data or credentials held in the DMZ
An SFTP server that moves files both into Blob and back out
No-code automation, auditing and alerts across every endpoint
Deployment on your terms, on-premises, in your own data center or any cloud, without hosting anything inside Azure

The spend goes on solving a file-exchange problem either way. Buy the thing that actually solves it.

How-to

How to automate a secure Azure Blob Storage transfer with Diplomat MFT

Step 1 of 5

Connect Azure Blob Storage

Add Azure Blob Storage as a connection in Diplomat MFT and point it at the container you want to move files to or from. Diplomat MFT connects through the native storage API, so you do not need to enable the paid SFTP endpoint. Credentials are stored and rotated centrally, not scattered across scripts.

Approach comparison

Azure Blob file transfer: which approach fits your requirement?

All four approaches are valid for the right job. The right choice depends on whether your transfers are recurring, encrypted, audited and cross-cloud, and on whether you want to pay for an always-on endpoint.

◑ Partial or possible with effort. The native endpoint and a branded front-end are honest choices for simple, always-on SFTP access. Diplomat MFT is for when transfers must be automated, encrypted, audited or cross-cloud, without paying to keep an endpoint running.

Before you pay for an always-on SFTP endpoint

Can you move files to Azure Blob Storage without managed file transfer?

Often, yes. For an occasional manual upload, Azure’s own tools, Storage Explorer and AzCopy, are the right answer, and the native SFTP endpoint is a genuine option too. The question is not whether you can move files to Azure Blob Storage, but whether the method holds up, and stays affordable, when the transfer is recurring, encrypted, audited, or dictated by regulations like HIPAA, GLBA or CMMC. Here is how the common approaches compare.

Native Azure Blob SFTP endpoint

Fine for a quick job

Lets an external client connect to a Blob container over SFTP, using the familiar protocol, with no server to run.

Reasonable for a simple, point-to-point SFTP handoff into or out of one storage account.
Enabling the endpoint carries an always-on hourly charge, on the order of 0.30 US dollars an hour, roughly 220 US dollars a month per storage account, whether or not you transfer anything. It authenticates local users only, with no Entra ID or Azure AD, and it does not schedule, encrypt with OpenPGP, or produce a transfer-level audit trail.

A branded SFTP front-end (for example, Couchdrop)

Works, with gaps

A hosted service puts a managed SFTP front door in front of Azure Blob Storage, so partners connect over SFTP without you running the native endpoint. This is what many people find when they search for an easier way to do Azure SFTP.

Solves inbound partner access, and adds SSH-key and multi-factor options on top of Blob.
It is another subscription, and it is a front door, not a transfer control plane. You still do not get scheduled cross-cloud automation, automated OpenPGP on every file, or one unified audit across Azure Blob, S3 and on-premises.

Roll-your-own VM SFTP server

Cheaper endpoint, hidden cost

A Linux VM runs an SFTP server in front of Blob storage, which several teams reach for once they see the native endpoint bill.

Lower endpoint cost than the native feature if the VM is small and well managed.
You now own patching, hardening, key management, uptime, logging and the audit trail forever. The saving on the endpoint fee is spent on operations and risk.

Custom scripts (AzCopy, SDK or PowerShell)

The hidden cost

A developer scripts AzCopy or the Azure SDK to push and pull blobs. Maximum control, and where many teams start.

Fine as a one-off if you have the developer skill and time to build and maintain it.
You now own error handling, retries, encryption, secret rotation, logging, and every SDK or API change forever. This is the brittle-script problem MFT exists to solve.

The pattern: each option is fine for its one job, but cost and risk rise with every recurring, regulated, or cross-cloud transfer. The native SFTP endpoint is a single-purpose door, and its real cost is the opportunity cost: you pay to keep it running and still have no browser portal, no automated OpenPGP, no cross-cloud workflows and no unified audit trail. For comparable spend, Diplomat MFT does all of that from one engine. That is where it earns its keep.

When Azure Blob transfers outgrow the workarounds

Why IT teams use Diplomat MFT with Azure Blob Storage

These are many of the events that trigger a move to Coviant Software’s Diplomat MFT when an organization moves files in and out of Azure Blob Storage.

The surprise SFTP line on your Azure bill

Someone enabled the native SFTP endpoint for a single job and never turned it off. Months later it is still there on the invoice, around 220 US dollars a month per storage account, for a door almost nobody uses. This is the moment teams look for a way to move files into Blob without paying to keep an endpoint running.

A partner needs to send files, but can’t be given an Entra identity

The native Azure SFTP endpoint authenticates local users only. When a supplier or client needs to deliver files into a container, you are creating and managing local credentials outside your identity system, with no central control, expiry or audit. You need external parties to deliver into a governed location without a VM, a standing endpoint, or an account in your directory.

A nightly load into Blob keeps breaking

A scheduled job pushes data into a container overnight, and when it fails there is no retry, no alert, and no log that survives. You find out when the downstream report is empty or a partner asks where the file is. This is where teams stop trusting a script for important transfers.

The auditor asked for every transfer to and from Blob, and you couldn’t produce it

A HIPAA, PCI DSS, or CMMC audit needs evidence that files moving to and from Azure Blob Storage were encrypted, logged, and controlled. The native endpoint and a pile of scripts were never designed to answer “show me every transfer in the last 90 days.”

An AzCopy or SDK script became load-bearing

What started as a quick AzCopy command now runs a partner feed, a backup, or a reporting pipeline, and only one person understands it. Every SDK or authentication change is a fire drill. The organization is one resignation away from a broken transfer it cannot fix.

You’re standardizing a sprawl of one-off Azure transfers

Different teams solved Azure Blob file movement in different ways, and IT now owns a museum of scripts, VMs, endpoints and manual steps with no consistent encryption, logging or ownership. The goal is one governed engine for all of it, with a single audit trail, before the next change breaks something.

Honest considerations

Diplomat MFT moves files, it does not integrate APIs. If you need application-level integration between Azure services and another system’s business logic, that is iPaaS territory (Boomi, MuleSoft, Azure Logic Apps). For an occasional manual upload to a container, Storage Explorer or AzCopy is the right choice.

Diplomat MFT earns its keep when transfers are recurring, encrypted, audited, or span more than one cloud, and when an always-on SFTP endpoint is the wrong way to pay for them. Coviant Software’s assessment will tell you honestly which side of that line you sit on. Diplomat MFT has never been breached in more than twenty years.

An honest gut-check

Do you actually need Diplomat MFT?

Two honest lists. The left one talks you out of buying. The right one is the risk if you are on the wrong side of the line and do nothing.

You probably do not need Diplomat MFT if…

If most of these are true, Azure’s own tools, the native endpoint, Storage Explorer and AzCopy, are the right, honest answer. Save your budget.

  • You move a handful of files by hand now and then
  • You have no compliance or audit obligation
  • Nothing needs encrypting beyond what Azure already does at rest
  • No transfers need to run on a schedule, unattended
  • You are not exchanging files with external partners
  • You do not mind, or pay for, an always-on SFTP endpoint
  • No one will ever ask you to prove what moved, when

If that is you, Azure’s native tools are the fit. Come back when a transfer becomes recurring or regulated.

But doing nothing has a cost, if you do need governance

If you are on the other side of that line and stay on scripts, endpoints and VMs, this is the debt that accrues quietly.

  • That always-on SFTP endpoint bills every hour, whether it is used or not
  • Technical debt piles up in scripts only one person understands
  • Staff dependency: the transfer is one resignation away from breaking
  • No visibility when an overnight job silently fails
  • Failed transfers surface only when a partner complains
  • Audit pain: no single record of who moved what, when
  • Compliance exposure that becomes a finding at the worst time

This is the problem a governed MFT engine exists to remove. If the left list is not you, this is the cost of waiting.

Not sure which side of the line you sit on?

Common questions

Azure Blob Storage SFTP: frequently asked questions

Yes. Azure Blob Storage has a native SFTP endpoint you can enable on a storage account that has a hierarchical namespace, which lets SFTP clients connect directly to a container. It authenticates local users only, with no Entra ID or Azure AD, and enabling it carries an always-on hourly charge, on the order of 0.30 US dollars an hour, roughly 220 US dollars a month per storage account, whether or not you move any files.

The SFTP endpoint is billed at an hourly rate for as long as it is enabled, on the order of 0.30 US dollars an hour, which is roughly 220 US dollars a month per storage account, on top of normal storage and transaction costs. The charge applies whenever the feature is enabled, regardless of transfer volume. Check Azure’s current pricing for exact figures.

No. The native SFTP endpoint authenticates local users you create on the storage account, not Entra ID or Azure AD identities, so those credentials sit outside your central identity system. Diplomat MFT connects through the native storage API with an account Key or a Blob SAS URL, so the credentials are managed centrally in Diplomat MFT instead of as local SFTP users.

No. Azure Blob Storage SFTP support is generally available, not deprecated. It is constrained, with local users only, an hourly cost, and single storage-account scope, which is why teams reach for a managed file transfer engine for anything beyond simple SFTP access, not because the feature is going away.

Yes. If the native SFTP endpoint is enabled, standard SFTP clients like WinSCP and FileZilla can connect to a container, which is fine for manual, ad hoc transfers. For recurring, scheduled, encrypted or audited transfers, a managed file transfer engine like Diplomat MFT automates the whole flow instead of a person driving a client by hand.

No. Diplomat MFT connects to Azure Blob Storage through the native storage API, using an account Key or a Blob SAS URL, so you do not need to enable the paid SFTP endpoint to move files in and out of Blob with Diplomat MFT. You would keep the native endpoint only if you separately need external partners to reach a container over SFTP, and even then the Diplomat MFT Web Transfer Portal or a governed SFTP flow is usually the better answer.

For your IT & security team

Operational questions engineers ask before they trust a transfer

Straight answers to the due-diligence questions that decide an MFT evaluation.

Diplomat MFT connects through the native Azure Blob connector, using the storage API with an account Key or a Blob SAS URL. It does not require the paid native SFTP endpoint, so you can move files in and out of Blob without an always-on SFTP charge.

Connection credentials, the account Key or Blob SAS URL, are held centrally in Diplomat MFT rather than embedded in scripts or scattered across ad hoc tools, so they can be rotated in one place.

A failed transfer raises an alert to designated individuals through the communications medium of choice, such as email, Slack or Teams. No silent failures.

Transactions carry a configurable retry policy, so a transient network or endpoint failure is retried automatically before it is escalated as a failure.

Diplomat MFT tracks what it has already moved, so a re-run does not blindly re-send files that already transferred successfully.

Behavior on name collisions, whether to overwrite, timestamp, or preserve, is configurable per transfer, so you control what happens when a file already exists in the container.

Every run logs who moved what, when, from and to where, and success or failure, and is exportable as compliance evidence.

Deeper technical detail lives in the Technology Briefs. Point your engineers at the OpenPGP, SFTP and secure-transfer briefs for the mechanics behind these answers.
