Secure file sharing for business, with control beyond encryption

Secure file sharing for business is a controlled way to send and receive files without losing visibility once information leaves your organisation. A good process lets you decide who can access a file, how long that access should remain available and what evidence is retained afterwards. That matters most when the files contain personal data, financial information, intellectual property or commercially sensitive material.

My MX Data is built for B2B exchange rather than open public sharing. MX supports named recipients, permissions, expiry settings and activity records, so teams can keep routine transfers practical while applying stronger controls to more sensitive exchanges.

For organisations exchanging files regularly with customers, suppliers or partners, the B2B secure file exchange page explains how that controlled approach works across organisational boundaries.

My MX Data can restrict an exchange to approved or named recipients rather than relying on an unrestricted public link. This gives the sender a clearer idea of who the file is intended for and reduces the ambiguity that comes with links which can be forwarded beyond the original audience.

Permission settings can also control what different people are allowed to view, download or manage. Multi-factor authentication adds another identity check before access is granted, while expiry settings can limit how long a recipient can reach the file.

Administrators can combine these controls according to the sensitivity of the exchange. The wider set of MX file sharing features includes user management, audit trails and other controls that support this approach.

Yes. MX is designed to support very large file transfers without arbitrary file-size restrictions. That is useful for CAD files, engineering data, high-resolution media, software packages, large document sets and complete project folders that are awkward to move through email or tools with restrictive upload limits.

Keeping the transfer in one controlled system can also reduce workarounds such as compressing files, splitting a dataset into several parts or switching to an unapproved service just to complete the job. Our large-file sharing guidance covers this use case in more detail.

MX records activity around a file exchange so authorised administrators and relevant senders can see more than the fact that a file was sent. Depending on the exchange, records may include uploads, access, downloads, comments, recipient activity, timestamps, transaction history and relevant user or IP details.

That visibility is useful for day-to-day follow-up. A team can check whether the current file has been downloaded, identify recipients who are still pending and review what happened if an exchange is later questioned.

It can also provide useful evidence for internal reviews and audit preparation. Our article on building a file audit trail explains why retaining this sort of activity record matters.

Files exchanged through MX are protected through several controls rather than one isolated security feature. MX uses AES-256 encryption as part of its security model, alongside named-recipient access, permission controls, multi-factor authentication, expiry settings and audit records.

For organisations handling particularly sensitive information, MX also offers ASR, which stands for Anonymise, Shard and Restore. ASR is separate from conventional encryption. It transforms the data so the underlying content is not recognisable, separates that transformed data into protected shards and restores the information for an authorised recipient.

The practical benefit is layered control around the whole exchange. You can read more about encrypted and controlled file sharing if protection during transfer is a primary requirement.

Email attachments and public sharing links can be convenient, but they often provide less control once a file has left the sender. Attachments may be duplicated across inboxes, while an open link can potentially be forwarded to somebody who was never part of the original exchange.

MX is designed around named and authorised recipients, configurable access conditions and a record of file activity. That means an organisation can keep a clearer connection between the file, the intended recipient and what happened afterwards.

This does not mean email or general cloud tools are inherently insecure. They often serve a different purpose. Where the priority is a controlled B2B handoff with traceability, a dedicated secure file sending process can provide more useful oversight.

Yes. MX supports expiry settings and configurable access conditions, allowing a sender or administrator to limit how long a recipient can reach information. This helps prevent a sensitive file remaining available indefinitely after the business reason for sharing it has passed.

Access can also be shaped through recipient selection, permissions and download conditions where the relevant workflow supports them. These controls are useful when different exchanges carry different levels of sensitivity, for example a routine supplier document versus confidential project data.

MX can provide technical controls and activity evidence that help an organisation support wider compliance responsibilities. Relevant capabilities include named-recipient access, multi-factor authentication, AES-256 encryption, expiry settings, permissions, audit trails and administrative oversight.

Using a secure file-exchange platform does not make an organisation compliant on its own. Compliance also depends on policies, procedures, lawful processing, staff behaviour, retention decisions, endpoint security, contracts and wider governance. The way MX is configured and used therefore matters.

Audit records can provide useful evidence during internal reviews by showing recipient activity, access and download history. Expiry controls and named recipients can also support more deliberate handling after information leaves the organisation.

For UK organisations handling personal data, our GDPR file-sharing guidance explains how these controls can fit into a broader data-protection approach. Organisations working to information-security standards may also find the ISO compliance page useful.
