WeTransfer Blocked at Work? Here's Why, and What to Do

You have a 2 GB file, an external partner waiting for it, and a browser page telling you the site is blocked by your organisation's policy.

The temptation is to route around it. Personal laptop, phone hotspot, personal Gmail, a USB stick. Before you do any of that, it's worth understanding what the block is actually for, because in most companies the policy has an approved path built into it and nobody told you where it is.

Why IT blocks file transfer services

It's almost never because they think WeTransfer is malware. The reasons are more boring and more structural.

No audit trail. When a file leaves through a personal transfer account, the company has no record of it. Nobody knows what left, who received it, or when. For a business under regulatory supervision, that gap is a finding waiting to happen. For any business, it's a blind spot.

Data loss prevention can't inspect it. Most companies run DLP tooling that scans outbound email for things like customer records, card numbers or source code. A file uploaded to a third-party site through a browser bypasses that inspection entirely.

It's a favourite phishing template. Fake transfer notification emails are one of the most persistent phishing patterns in circulation. If employees are trained to treat every transfer notification with suspicion, and the real service is blocked, the fake ones lose most of their power.

Malware delivery. Legitimate file services are useful to attackers precisely because they're trusted. A link from a known domain gets past filters and past people.

Departing employees. A significant share of data walking out the door leaves in the final two weeks of someone's notice period. Uncontrolled transfer services are the obvious route.

Notice that none of these is about you personally. The block is a control on a category, not an accusation.

The workarounds, and why they're worse than the problem

Every one of these is common. Every one is a bad idea, and not for abstract reasons.

Personal email. Sending company files to your own Gmail to forward them onward is, in most employment contracts and security policies, a reportable data transfer. It's also the single most common thing that turns a minor incident into a disciplinary matter, because it's trivially visible in mail logs. You will not get away with it quietly.

Personal cloud storage. Same problem, plus the file now lives in an account the company can't reach and can't wipe when you leave.

USB drives. Frequently blocked at the endpoint anyway, and when they aren't, they get lost. An unencrypted stick in a taxi is a textbook breach notification.

Phone hotspot to dodge the network block. This is deliberately circumventing a security control. Whatever you think of the policy, doing this knowingly is a different category of problem from not knowing the policy existed.

A random alternative service you found in five minutes. The block is on WeTransfer specifically, so people go and find something less well known. From a risk perspective this is the worst option in the list, because you've now uploaded company data to a service nobody has assessed.

If your genuine problem is that the approved tools don't work for large files, that's a real complaint and it deserves a real answer. The answer is to raise it, not to route around it.

What to do instead

Check what's already approved. Most companies with a block have a sanctioned alternative and haven't communicated it well. Look for a corporate Dropbox, SharePoint or Box account, a managed transfer service, or a secure email gateway with a large-file option. Ask a colleague who deals with external partners regularly, they'll know.

Ask the service desk directly. "I need to send a 2 GB video to an external agency, what's the supported way to do that?" is a completely normal ticket. You'll usually get an answer the same day.

Ask the recipient's side. If you're sending to a large client, they often have an inbound portal precisely for this. Their process satisfies their compliance team and sidesteps yours.

Request an exception with a business case. If there's genuinely no approved route, this is the escalation. Details below.

Send less. Half the time the file doesn't need to be that big. An export at review resolution, a subset of the data, or a redacted version might sail through the approved channel that the full file won't.

How to ask for an exception and actually get it

Security teams say no to vague requests and yes to specific ones. Give them what they need to evaluate.

A request that works looks like this:

I send video files of 1 to 4 GB to three external production partners roughly weekly. Email attachments cap at 25 MB and our SharePoint external sharing is disabled for these domains. I'd like an approved way to do this.

Requirements I think matter: password protection per file, an expiry date, a download limit, and a record of who downloaded what. Happy to use whatever tool you prefer, and happy to run it through a review process.

That gives them the volume, the frequency, the failed alternatives and the controls you're already thinking about. It reads like someone trying to solve the problem with them rather than around them.

What doesn't work: "WeTransfer is blocked, can you unblock it?" That's a request to remove a control with no context, and the default answer is no.

What makes a transfer service approvable

If you're on the other side of this conversation, or you're building the business case, these are the properties security teams actually look for.

Access control beyond the URL. Password protection at minimum. Recipient email verification is better, because it produces a record of who opened it rather than just that someone did.

Enforced expiry. Links that die on a schedule, not links that live until someone remembers to revoke them.

Download limits. A cap makes onward redistribution visible rather than silent.

Logging. Who sent what, when, and whether it was collected. This is usually the deciding factor, because it's what turns an uncontrolled channel into an auditable one.

Known data location. Which country, which provider. Procurement will ask.

A data processing agreement. Non-negotiable for anything touching personal data.

Sensible defaults. A tool where the safe configuration requires five deliberate clicks will be used unsafely. One where expiry and download caps are part of the send flow gets configured correctly by default.

That last point matters more than any feature list. Shadow IT exists because approved tools are painful. The way to reduce it is to make the sanctioned path the easy one, which we went into in managing file sharing across a remote team.

If you're the one making the policy

Blocking a single domain buys you very little. The same behaviour reappears on Dropbox, Google Drive, or a service you've never heard of, and now you have less visibility than before.

More effective:

Write the policy at the category level, covering unapproved public file sharing generally
Name and promote a specific approved alternative, loudly and repeatedly
Make the approved path work for genuinely large files, or people will find another way
Run a lightweight exception process so requests come to you rather than around you
Watch for the signal in your logs: a spike in blocked file-sharing attempts is a sign the approved tools aren't good enough for the job

The broader inter-company version of this problem is covered in how to share files between different companies safely, and the individual habits that cause most incidents are in common file sharing security mistakes.

The short version

The block is there for reasons that mostly aren't about you. Routing around it converts a workflow annoyance into a policy violation with your name on it, and mail logs make it visible.

Find the approved path, and if there isn't one, ask for it with specifics. In most organisations that conversation takes a day and permanently solves a problem you were about to solve badly.

How Comfyfile Can Help

If you're putting together the case for an approved transfer route, the controls security teams ask for are the ones Comfyfile builds into the send flow: a password per share, an expiry you set, a download cap, and optional email verification so the recipient has to confirm their address before the file unlocks. Per-share download and view counts give you a record of what was collected. Files are stored on EU-based servers and removed when the expiry passes. Comfyfile isn't independently certified under any compliance framework, so check that against your organisation's procurement requirements.
