Secure file sharing for financial services and sensitive client information.

Financial services firms routinely exchange client records, financial information, due-diligence documents, audit material and regulatory evidence with people outside their own network. Those files can be commercially sensitive or contain personal data, so the exchange process needs clear controls around who receives them and what happens afterwards.

My MX Data is built for controlled B2B file exchange. MX can restrict access to named recipients, apply permissions and expiry settings, protect information with AES-256 encryption and retain records of access, downloads and other activity.

That gives finance teams a more consistent way to send information to clients, auditors, advisers and counterparties without relying on unrestricted public links or oversized email attachments.

Where exchanges involve customers directly, our secure client file-sharing guidance explains how controlled external delivery can support a professional client experience as well as stronger oversight. The same process remains useful when counterparties exchange sensitive information repeatedly.

My MX Data can limit financial files to named or approved recipients rather than making them available through an unrestricted public link. Permissions can then determine who may view, download or manage the information, which is useful when client records or due-diligence packs should only be available to a defined group.

Multi-factor authentication can add another identity check before access is granted, while expiry settings and relevant download conditions can narrow how long material remains available. Administrators can also manage users and roles across teams. A finance team can therefore apply tighter access to confidential client material without creating a separate process for every recipient.

These controls help a firm apply a more deliberate process to external exchanges without treating every file as equally sensitive. You can read more about secure and encrypted file exchange across the wider MX platform.

Yes. MX is designed to transfer very large files and datasets without arbitrary file-size restrictions. Financial services teams can therefore exchange substantial audit packs, document collections, reporting datasets or supporting evidence without splitting the material purely to satisfy an attachment limit.

Keeping a large transfer within the same controlled workflow also preserves recipient restrictions and activity records around the exchange. That can be more manageable than moving one oversized file through a separate consumer transfer service. It also keeps a complete submission together for easier checking.

Our large-file sharing page covers this use case in more detail, including why size limits can create unnecessary workarounds.

Relevant senders and administrators can review activity associated with financial file exchanges. Depending on the transaction, records may include uploads, access, downloads, comments, timestamps, recipient activity, transaction history and relevant user or IP information.

That visibility is useful when a team needs to confirm whether a client, auditor or adviser has received a document pack, identify an exchange that is still pending or investigate what happened after sensitive material left the organisation.

For compliance and governance teams, retained activity evidence can also support internal reviews and audit preparation. It does not replace the firm's own policies or regulatory controls, but it gives them a clearer factual record of how a particular exchange was handled and which recipients interacted with it. For recurring client or counterparty exchanges, that history can reduce reliance on individual inboxes and make handovers between colleagues easier to manage.

Our guide to file audit trails and accountability explains why structured activity records are useful when an organisation needs evidence rather than assumptions.

MX uses several controls around financial file exchange rather than relying on a single security measure. AES-256 encryption helps protect information during relevant stages of storage and transfer, while named-recipient access and permissions focus on who should be able to reach the file.

Multi-factor authentication can add another identity check, and expiry settings can reduce the chance of confidential material remaining available longer than necessary. Audit records then provide evidence of access, downloads and other transaction activity.

For particularly sensitive information, MX can also use ASR, which stands for Anonymise, Shard and Restore. ASR transforms the data, separates it into protected shards and restores it for an authorised recipient. It is an additional method of protection, not another name for encryption.

Teams reviewing their wider approach can also explore the MX security and exchange features that sit around day-to-day file delivery. Different transactions can carry tighter controls where confidentiality or auditability requires them.

Email attachments and public links can work for routine communication, but financial teams often need stronger evidence around sensitive exchanges. A forwarded attachment may create several unmanaged copies, and an open link can make it harder to connect access with the person who was actually intended to receive the material.

MX is designed around controlled, named-recipient exchange. Permissions, multi-factor authentication, expiry settings and activity records give a firm more structure around external delivery, particularly when client records, due-diligence files or audit information are involved. That gives several colleagues a common record of the handoff rather than separate personal copies.

That does not mean email or mainstream cloud platforms are inherently unsafe. They serve wider communication, storage and collaboration needs. MX is focused on situations where the organisation wants clearer control and traceability once a file crosses an organisational boundary.

For a broader comparison of this approach, see our B2B secure file exchange page.

Yes. Finance teams can use expiry settings so a client file, audit pack or other sensitive document does not remain accessible indefinitely after its business purpose has ended. Named-recipient controls and relevant download conditions can add further restrictions where a transaction calls for them.

This is useful for time-limited reviews, due-diligence exercises or exchanges with external advisers where access is appropriate for a defined period rather than permanently. The access window can reflect the sensitivity of the material and the actual business need.

Activity records sit alongside those controls, giving the firm a clearer view of what happened while access was available. That supports a more consistent approach to external file handling and later review.

MX can provide controls and evidence that may support wider financial-services compliance responsibilities, including access management, encryption, multi-factor authentication, expiry settings, administrative oversight and activity records. Those capabilities can be relevant to UK GDPR, the Data Protection Act 2018, ISO 27001, supplier assurance and other governance requirements that affect how sensitive information is handled.

No file-sharing platform makes a financial organisation compliant on its own. Compliance also depends on policies, lawful processing, retention decisions, contracts, staff behaviour, endpoint security, risk management and the way the service is configured.

The practical value of MX is that it can give security and compliance teams clearer controls around a specific part of the process: information moving between the firm and clients, auditors, advisers or other external parties.

Our GDPR file-sharing guidance looks more closely at the relationship between technical controls and wider data-protection responsibilities.
