How MX Stacks Up Against the Competition

Most people turn to Dropbox, Google Drive or WeTransfer for quick file movement. My MX Data focuses on transfers that demand security, detailed tracking and encrypted protection from start to finish, keeping control firmly in your hands.

Its strongest points are in Security & Compliance, File Control, Collaboration and Large File Handling.

✅Quantum-Resilient Encryption – MX uses its ASR methodology to defend data against future quantum computing threats. ℹ️ What does this mean?ASR (Anonymise, Shard, Restore) breaks information into anonymised shards, sends them via separate secure routes, and restores them only for authorised recipients, giving stronger safeguards than conventional AES-256 encryption.

✅Complete Audit Logging – Every send, view, or download is captured with precise timestamps, helping organisations meet demanding compliance checks.

✅Supports GDPR, UK DPA & ISO 27001 – Maintains legal alignment through robust encryption and strict access controls.

❌WeTransfer stores data without encryption at rest, making it unsuitable for confidential exchanges.

❌Google Drive and Dropbox require extra security setup before matching enterprise compliance levels.

Security & Compliance

✅Authorised Named User Access – Every shared file is tied to a verified, named recipient, sharply reducing the risk of accidental or unauthorised disclosure.

✅Data Location Control – Select the hosting region that best suits your compliance obligations and client expectations.

🟡Straightforward File Handling – Upload, download, and monitor exchanges without the complexity of a full document management system.

❌No Continuous Sync – Designed for secure, finalised transfers rather than constant synchronisation between devices.

File & Access Management

✅Confidential Business Transfers – Exchange critical business files with strong encryption and complete tracking of every movement, giving both sides clarity and trust.

✅Built-In Secure Messaging – Keep project chats in the same place as the files, avoiding email clutter and stray attachments.

✅Custom-Branded Portals – Clients and colleagues see your domain, your colours, and your logo during every step of a file exchange.

🟡No Real-Time Editing – All changes to a document need to be made before it is sent via MX for secure delivery.

Collaboration

✅No Size Restrictions – While Google Drive caps uploads at 750GB per day and WeTransfer free accounts stop at 2GB, MX lets businesses move files of any size without limits holding them back.

✅Branded Secure Intake – Collect sensitive material from clients using encrypted portals that carry your firm’s identity. Standard consumer apps don’t give you this controlled, professional intake process.

❌Not for Permanent Storage – MX is built for swift and secure movement of data, not for long-term cloud archiving like Dropbox or OneDrive.

FAQs

1
Technology & Credibility
Why is MX suited for B2B secure file exchange?

MX is built specifically for B2B secure file exchange, not as a general storage drive. Every transfer is encrypted with our quantum secure patented methodology, meaning data is anonymised, split into shards, and then restored only for the intended recipient. This avoids the risks of ordinary cloud services where files can linger indefinitely.

Businesses choose MX because it facilitates compliance with strict frameworks such as GDPR, ISO 27001 and the UK Data Protection Act. In fact, research suggests around 65% of companies in sectors like finance, healthcare and legal already rely on enterprise-grade encryption solutions to stay compliant (Statista).

Unlike consumer platforms, MX also records a full audit trail, ensuring each file handoff is transparent. You can explore these capabilities further in our Features page or by browsing Case Studies from firms that already trust MX for regulated exchanges.

Can MX manage large data volumes between partner firms?

Yes, MX supports unlimited file size transfers. Whether you are moving gigabytes of CAD drawings, raw video archives or detailed financial reports, the platform is optimised for high volume data while retaining full encryption.

  • Ultra-Fast Sharing: Large files transfer quickly without sacrificing confidentiality.
  • No Arbitrary Caps: Unlike WeTransfer or Dropbox, MX has no artificial size limits.
  • Cross-Organisation Ready: Designed to handle repeated transfers between trusted partner domains.

According to industry analysis, the secure file transfer market is projected to grow from $2.5 billion in 2025 to $3.26 billion by 2028 (GlobeNewswire), reflecting demand for exactly these large-scale exchanges.

How does MX reduce compliance risk in cross-company transfers?

Cross-company exchanges are often the most vulnerable point in data handling. MX reduces risk by applying its named-user access model, ensuring that files cannot be forwarded beyond the intended recipient. This gives businesses the traceability needed to demonstrate responsible data stewardship.

MX facilitates compliance rather than guaranteeing it, but the combination of end-to-end encryption, expiry policies and detailed audit logs gives organisations a structured way to evidence their efforts. You can find additional insights in our GDPR page and ISO Compliance guide.

Does MX provide audit trails for B2B exchanges?

Yes, MX automatically creates comprehensive audit trails. Every upload, download and recipient action is logged with time, date and location details, making it straightforward to trace the full lifecycle of a file. This is especially important where regulators expect evidence of responsible data handling.

Audit logs can be exported and retained for internal governance or external inspections, reducing the need for costly add-on compliance tools. As a result, MX often replaces the patchwork of file transfer and monitoring systems businesses try to stitch together. Learn more about these safeguards in our blog: Robust Security Features for Data Sharing.

Efficiency & Business Value
How does secure B2B sharing improve operational efficiency?

Traditional file sharing is often plagued by size caps, unreliable links, or security doubts that slow down projects. MX eliminates these barriers, allowing firms to focus on outcomes rather than technical hurdles. By replacing email attachments and unsecured drives, teams report saving hours every week on administration alone.

  • Streamlined Workflow: Files flow directly to approved users without detours.
  • Lower Risk of Rework: Version control reduces duplication and miscommunication.
  • Better Partner Trust: Clients and vendors receive files confidently, avoiding back-and-forth clarifications.

Evidence shows that 39% of all business data uploaded to the cloud is used primarily for file sharing (6sense), underlining the value of making those exchanges efficient rather than cumbersome.

Can MX be tailored to different industry requirements?

Yes, MX provides industry-specific flexibility. Through its metadata APIs and governance settings, the platform adapts to fields as varied as engineering, healthcare and finance. For instance, healthcare providers can align file exchange with HIPAA frameworks, while manufacturers can control the distribution of CAD schematics with expiry dates.

Our Case Studies illustrate how organisations across sectors configure MX to suit their workflows. In practice, this avoids the need for separate file transfer solutions per department, reducing cost and complexity.

3
Setup, Support & Integration
Is MX simple for non-technical external partners to use?

Yes, MX is deliberately straightforward. External partners do not need specialist knowledge or training. Each invited user receives secure credentials, and from there the interface is intuitive. Uploading or downloading is no more complex than using a standard email attachment, only with much higher protection.

This simplicity is essential in B2B environments where partners vary in technical expertise. By reducing the learning curve, MX avoids bottlenecks and ensures projects keep moving. For a demonstration, you can start a free trial and test it with partners directly.

What onboarding support is available for new B2B partners?

New partners receive dedicated onboarding assistance to ensure a smooth start. This includes simple setup guides, access to our Help Centre, and responsive customer support. Larger enterprises may also appoint an MX account manager to coordinate multiple partners and departments.

  • Guided Setup: Step-by-step material for both administrators and end users.
  • Live Assistance: Email and ticketing for quick answers to technical questions.
  • Ongoing Training: Refresher resources to keep teams confident over time.

We recommend exploring our Pricing and Contact Us pages to see which onboarding tier fits your organisation. You can also learn more in our blog post: Fostering Remote Work Collaboration.
