Sending files to clients and partners is a daily task for most teams. The easiest route feels obvious: attach the file to an email or drop it into a shared cloud folder and send the link. Both methods work until they don't. A sensitive contract lands in the wrong inbox. A shared link stays active long after the project ends. You have no way to know if the recipient actually downloaded the file or if it was forwarded to someone else. These gaps matter, especially when you are handling financial records, legal documents or client data.
Email attachments and personal cloud links are not built for secure business file transfer. They lack the controls a team needs to stay confident about who sees what, and when.
The risks hiding in email attachments and open links
Email is not secure file transfer. When you attach a file to an email, it travels through multiple servers and sits in the recipient's inbox indefinitely. If their email account is compromised, so is your file. You have no way to revoke access or know when the file was opened. Large attachments also clog inboxes and slow down email systems, which creates friction for both sender and receiver.
Shared cloud links feel more modern, but they carry their own problems. A link to a Google Drive or OneDrive folder often stays active forever unless you remember to delete it manually. Anyone who has the link can access it, and you may not know if it was shared further. Some links grant edit permissions by default, which means a recipient could alter the file without your knowledge. If you need to send the same file to multiple people, you end up managing a pile of separate links and hoping you revoke them all.
What secure file transfer actually requires
Secure file transfer for business means you can control access and prove what happened. A proper solution includes four key features. First, expiring links: the ability to set a date after which the file can no longer be downloaded, so sensitive documents do not stay accessible forever. Second, access control: the option to decide who can download the file and whether they can edit it. Third, audit logs: a record of who downloaded the file, when they downloaded it and from which device, so you have proof of access if you need it. Fourth, a clear storage location: you should know exactly where your files are stored and who can access them on the server side.
These features are not optional extras. They are the foundation of trust when you are handing over sensitive information.
Business cloud storage already offers these controls
If your team uses Microsoft 365 or Google Workspace, you may already have access to secure file transfer tools built into those platforms. Microsoft 365 and Google Workspace both offer expiring links, granular access control (you can choose who sees the file and whether they can edit it) and audit logs that show download activity. These tools work well for teams that are already invested in those ecosystems and do not need a separate service.
However, business cloud storage is designed for collaboration and document management, not file transfer. If you need a dedicated service that focuses only on sending files securely to external parties, or if you want a solution that does not depend on a larger platform subscription, a standalone secure file transfer service may fit your workflow better.
Choosing between platforms
Start by asking yourself a few questions. Does your team already use Microsoft 365 or Google Workspace with business editions? If yes, test their native file-sharing controls first. They may be enough. Do you need to send files to people outside your organisation who do not have those accounts? Then a dedicated service becomes more practical. Are audit logs and expiring links non-negotiable for your industry or your clients? If so, make sure your chosen platform offers both.
The right choice depends on your team's size, the sensitivity of the files you send and how often you send them. There is no single answer that works for everyone.
Where to start
If you decide you need a dedicated secure file transfer service, Upward Technologies offers Transfer, a secure file transfer service live since 24 September 2026 at transfer.upwardtech.nl. You might also review your current cloud storage setup to see whether the access controls already built in are sufficient for your needs.
The goal is simple: send sensitive files with confidence, know who accessed them and be able to stop access when the time comes.
