Controlled, auditable file exchange for smaller organisations

Secure file sharing for small business, with control you can evidence

Sensitive file exchange is rarely just an IT task. It affects client trust, operational risk and the evidence available when a transfer is questioned. My MX Data gives small teams a practical approach to secure file sharing for business, covering contracts, financial records, client files and intellectual property, with named-user access, detailed audit trails and no public links. It fits alongside existing systems rather than asking the business to replace them.

Where exposure begins

The real risk is often the sharing process, not the file itself.

A transfer can work technically and still be difficult to defend. The uncomfortable questions usually arrive later: who had access, whether the recipient was authorised, how long access remained open, and whether the business can prove which version was received.

For smaller organisations, the answer is not more complexity. It is a clear, repeatable way to send files securely when the information is sensitive or the handoff may need to be explained. My MX Data provides that route while keeping the sender and recipient experience practical.

A controlled layer, not a replacement

Use familiar tools for everyday work. Use MX when the handoff needs stronger governance.

Google Drive, Dropbox, OneDrive, SharePoint and WeTransfer are useful for many storage, synchronisation, co-authoring and convenience-led tasks. My MX Data addresses a different requirement. It provides controlled, auditable exchange between known users. This distinction is also useful when assessing cloud file sharing for business, because the right choice depends on the job the tool is expected to perform.

General cloud and transfer tools

  • Primarily designed around folders, synchronisation, collaboration or shareable links.
  • Recipient controls depend on the product, licence and configuration selected.
  • Well suited to broad day-to-day productivity and low-risk collaboration.

My MX Data

  • Access is assigned to named users rather than an open download link.
  • Expiry, permissions and download restrictions can be applied to the exchange.
  • The workflow is purpose-built for controlled movement of sensitive files.
Patented quantum secure methodology

An additional protection layer for sensitive exchanges.

Alongside AES-256 protection, My MX Data uses its patented quantum secure methodology, known as ASR. Files are anonymised, separated into shards and restored through the controlled process for an authorised user. The purpose is to reduce exposure and strengthen long-term data protection without overstating what any security control can guarantee.

01

Separate identity from content

Identifying information is separated from the file content, which reduces the value and context of an isolated fragment.

02

Distribute incomplete fragments

The file is divided into shards so that no single storage location holds the complete, readable content.

03

Restore through authorised access

The file is reconstructed through the controlled MX process for the intended recipient, with the associated activity recorded.

ASR should not be described as unbreakable, quantum-proof or a compliance guarantee. It is a patented quantum secure methodology that adds a further layer of control to encrypted file sharing and supports a more resilient approach to sensitive data exchange.

Control without unnecessary complexity

The controls a small team needs, without a full document management system.

Secure file sharing software only works if people use it consistently. MX keeps the handoff straightforward while adding the access, evidence and governance controls that matter. The wider is designed to support real business workflows rather than security theory.

Named-user access

Assign files to known recipients rather than relying on public links that can be copied or forwarded.

Detailed audit trails

See who accessed a file, when activity occurred and what actions were taken during the exchange.

Expiry and permissions

Apply expiry dates, recipient permissions and download restrictions to suit the sensitivity of each handoff.

Unlimited file size

Move large media, project archives, design files and technical datasets without splitting them into awkward parts.

MX Conversations

Keep comments and project discussion close to the related file activity instead of scattering context across inboxes.

Branded client portals

Use your logo, colours and domain to give customers and partners a professional, consistent experience.

Data sovereignty options

Choose appropriate storage locations for data shards to help support regional governance requirements.

Metadata API

Connect transfer metadata to engineering, finance, healthcare and other operational workflows where required.

Version clarity

Use controlled file updates to help recipients work from the intended version rather than an old email attachment.

A clear handoff from start to finish

A controlled exchange that remains simple for sender and recipient.

A secure file transfer process should not require a specialist server or a long training programme. The sender selects the recipient, applies the appropriate controls and sends the file through the browser. For inbound collection, a secure upload portal gives clients and partners the same controlled route in the opposite direction.

01

Identify the authorised recipient

Select the person or group that should receive the file. Access is associated with named users, not an unrestricted public link.

02

Apply proportionate controls

Set expiry, permissions and download rules that reflect the purpose, sensitivity and expected life of the exchange.

03

Transfer through one approved route

Send the complete file without splitting, compressing or moving the work to an unapproved consumer service.

04

Retain evidence of the handoff

Review the activity record afterwards and answer questions with documented evidence rather than memory or email threads.

Compliance-supporting controls

Better evidence for the compliance work you already do.

My MX Data does not make an organisation compliant by itself. It provides named-user access, expiry settings, permissions, audit evidence and data-sovereignty options that can help facilitate GDPR-focused file sharing and support ISO 27001-aligned processes.

For a small business, the practical value is explainability. When a client, insurer, auditor or internal reviewer asks how sensitive information was sent, the organisation has a clearer record of the recipient, controls and activity associated with the exchange.

Plain speaking: compliance also depends on lawful basis, policies, retention decisions, staff behaviour and wider operational controls. MX supports that framework; it does not replace it or remove the organisation's responsibilities.

Evidence for review

Detailed audit trails help the business reconstruct a sensitive exchange and provide a clearer record during client, assurance or audit activity.

Deliberate access control

Named users, permissions and expiry settings help demonstrate that access was limited intentionally rather than left open by default.

Data sovereignty choices

Storage-location options can support regional, contractual and internal information-handling requirements.

Reduced unnecessary exposure

Expiry and removal controls help limit how long sensitive information remains available after the business purpose has been met.

The sensitivity of the work matters more than company size

Small firms still handle information that needs serious control.

A smaller organisation may have fewer users, but it can still hold privileged advice, financial records, personal data, intellectual property and commercially sensitive project material. MX provides a proportionate file sharing solution for those exchanges.

Legal and professional services

Move case files, agreements and due-diligence material through a controlled process. See how MX supports file sharing for law firms.

Engineering and manufacturing

Exchange CAD files, drawings, specifications and intellectual property across project and supplier networks using a controlled B2B file exchange.

Technology and creative teams

Deliver source packages, media, prototypes and project archives through a consistent route for secure large file transfer.

Client-facing consultancies

Provide a branded route for proposals, reports, research and confidential deliverables with secure client file sharing.

Secure inbound collection

Give clients and partners a controlled place to submit documents rather than asking them to email attachments or choose their own tool.

A proportionate starting point

Choose the level of control that fits the team and the risk.

Business Pro, Business Premium and Enterprise options support different user numbers, collaboration needs and governance requirements. The 7-day trial allows a small team to test the real sending and receiving process before making a longer-term decision.

Questions to resolve before changing the process

What a small business should establish before adopting a new sharing route.

The best secure file sharing for small business is not simply the product with the longest feature list. It is the option that gives users a practical workflow and gives the organisation evidence it can stand behind.

Email and consumer transfer services remain convenient for many low-risk tasks. The concern begins when the file contains personal, financial, privileged or commercially sensitive information and the process offers limited control over forwarding, expiry, recipient identity or the evidence available afterwards.

MX gives those higher-risk handoffs a dedicated route. Named-user access, permissions and a detailed activity record help the business show what happened without asking staff to abandon familiar tools for drafting and everyday collaboration.

Not necessarily. Those platforms are useful for storage, synchronisation, shared folders and live collaboration. MX is focused on controlled file exchange between known users, particularly where the information is sensitive or the handoff may need to be evidenced later.

Many organisations therefore use both. Work is created and edited in the existing productivity environment, then the final sensitive handoff is moved through MX to the client, supplier, adviser or project partner.

No specialist desktop application is required for the standard browser-based experience. The recipient follows the invitation and verification process associated with their named access instead of opening an unrestricted public link.

The aim is to keep the interaction clear for clients and suppliers while preserving a more accountable record for the sending organisation. Security controls are most useful when people can follow them without creating new workarounds.

MX can help facilitate compliance efforts through access controls, expiry settings, audit evidence and data-sovereignty options. These capabilities can support GDPR, the UK Data Protection Act and ISO 27001-aligned processes by making sensitive exchanges more controlled and easier to evidence.

It does not guarantee compliance. Your organisation remains responsible for lawful basis, policy, retention, staff behaviour, supplier oversight and its wider information-governance framework. MX provides practical controls within that broader programme.

It refers to the patented ASR process: Anonymise, Shard, Restore. Files are anonymised, separated into shards and restored through the controlled process for authorised users. This adds a further layer of protection beyond conventional file sharing.

The methodology is designed to strengthen long-term data protection and contribute to resilience against evolving threats. It should not be described as unbreakable, impossible to compromise or a substitute for sound security governance.

Yes. MX supports unlimited file size transfers, which is useful for video, design, engineering, imaging, data and project files that might otherwise be split into parts or moved through an unapproved workaround.

Bandwidth and recipient availability still need sensible operational planning, but the absence of a platform file-size cap gives the team one approved process for ordinary documents and very large deliveries.

The standard service is cloud based, so a team can begin without deploying a traditional file-transfer server. Users can be added, branding configured and exchange controls introduced through a focused setup process.

The exact rollout depends on internal approvals and governance requirements. The 7-day trial gives up to five users an opportunity to test real workflows before selecting a plan or discussing a more tailored deployment.

Yes. Teams can continue creating and editing documents in the systems they already know, then use MX for the controlled internal or external handoff. This avoids unnecessary disruption while giving sensitive exchanges a more consistent access and audit process.

Where a business has more specialised workflows, metadata APIs can connect transfer records with engineering, finance, healthcare and other operational systems. The objective is to strengthen the handoff, not redesign the whole working environment.
