Secure client file sharing for sensitive external work.

Secure client file sharing is a controlled way to exchange documents and data with customers or clients without relying on open public links or long email chains. The aim is to keep a clearer record of who the information was intended for and what happened after it was sent, without making the client experience unnecessarily awkward.

My MX Data supports named-recipient access, permissions, expiry settings, large-file transfer and audit records. That can be useful for accountancy, legal, finance, consultancy and other professional services where client files may contain personal, financial or commercially sensitive information.

A client-facing workflow should still feel practical. MX can also support branded upload portals in relevant configurations, giving external parties a more recognisable route for providing information. See the secure upload portal page for inbound document collection.

My MX Data can restrict client files to approved or named recipients, which is more controlled than sending an unrestricted link that may be forwarded beyond the intended audience. This is particularly useful for confidential reports, financial records, contracts or case material.

Permissions can determine what different people are allowed to view, download or manage. Multi-factor authentication adds another identity check, while expiry settings can limit how long a client or adviser can continue to access the information.

These controls help the organisation apply a more consistent process across client exchanges. The B2B secure file-exchange page explains how the same approach can extend across customers, suppliers and professional partners.

Yes. MX is designed to support very large file transfers without arbitrary file-size restrictions. Clients can therefore receive large document sets, technical data, high-resolution media or project folders without forcing the sender to split the information into several separate exchanges. That keeps the delivery easier to follow and reduces the chance of one part of a client package being missed.

This can be useful for professional services, design, engineering or media work where the client deliverable is simply too large for email. The large-file sharing page covers the transfer use case in more detail.

MX records activity around client exchanges, giving authorised administrators and relevant senders a clearer view of what happened after information was shared. Depending on the transaction, records may include uploads, access, downloads, comments, timestamps, recipient activity, user information and relevant IP details.

That is useful when a client says a document has not arrived, a team needs to confirm whether a deliverable was downloaded or an adviser wants to know which version was accessed. It reduces the need to reconstruct the story later from scattered email threads.

Notifications can also help teams keep track of downloads, comments, expiring access or actions still required. Where several related exchanges take place, linked transactions and MX Conversations can keep file activity and discussion connected. This is useful for long-running client work involving several document requests or revisions. Teams can keep each exchange distinct while still seeing how related transactions connect.

For organisations that need stronger evidence around external sharing, our article on file audit trails explains how access and activity records can support internal reviews and client-facing accountability.

Client files can be protected with several controls working together. MX uses AES-256 encryption as part of its security model, alongside named-recipient access, permissions, multi-factor authentication, expiry settings and activity records.

For especially sensitive information, ASR provides an additional method of protection by anonymising the data, separating the transformed information into protected shards and restoring it for an authorised recipient. ASR is separate from conventional encryption.

These controls can be useful for financial records, contracts, case files or confidential project material. Permission settings and expiry conditions can tailor access to the sensitivity of the exchange, while audit records provide evidence of recipient activity. It still needs sensible configuration and account management. The encrypted file-sharing page explains the protection approach in more detail.

Email attachments are familiar, but they can duplicate sensitive documents across inboxes and offer limited visibility once the message has been sent. Public links may be convenient too, although forwarding the link can separate the file from the audience originally intended to receive it.

MX keeps the client exchange tied to named recipients, configurable access conditions and an activity record. This gives the organisation clearer evidence of delivery and access while providing a more consistent process for staff who handle client files regularly. It can also reduce the need to chase clients manually because teams can see whether an exchange is still pending or has already been downloaded.

Email and mainstream cloud tools still have valid uses. MX is designed for the exchanges where greater control is justified. The secure file-sending page explains how this controlled handoff differs from ordinary attachment sharing.

Yes. MX supports expiry settings and configurable access conditions, so client files do not have to remain available indefinitely after the purpose of the exchange has passed. This can be helpful for time-sensitive reports, contracts, due-diligence material or temporary project access, particularly where a file should not remain reachable once a review or engagement has finished.

Access can also be shaped through recipient selection, permissions and download conditions where supported. The organisation can therefore apply tighter controls to sensitive client information without making every routine exchange unnecessarily restrictive.

Yes. MX can provide technical controls and audit evidence that may support an organisation's wider compliance responsibilities when client files contain personal, financial or regulated information. Relevant capabilities include named recipients, permissions, multi-factor authentication, encryption, expiry settings and activity records.

These controls can help organisations show that client information was shared through a defined process rather than an open link or unmanaged email attachment. Audit records may also support investigations, internal reviews and evidence gathering, especially where a firm needs to show how a sensitive client exchange was handled.

The platform does not make a business compliant by itself. Compliance still depends on lawful processing, contracts, retention, staff procedures, endpoint security, risk assessment and the way the service is configured and used.
