How MX Stacks Up Against the Competition

Where Dropbox prioritises convenience, My MX Data prioritises encrypted compliance, file oversight and accountability, giving regulated sectors the confidence to operate without compromise.

Its capability is clear in Security & Compliance, File Control, Collaboration and Handling Large Files.

✅Quantum-Resilient Transfer – MX applies its ASR methodology so very large files move securely without weakening protection. ℹ️ What does this mean?ASR (Anonymise, Shard, Restore) splits data into anonymised shards, routes them through separate secure channels, and restores them only for authorised recipients, offering sturdier safeguards than AES-256 alone.

✅End-to-End Transfer Logs – Every stage is recorded, from upload to receipt, giving clear traceability for big deliveries.

✅Supports GDPR, UK DPA & ISO 27001 – Combines careful encryption and controlled access for compliant large file movement.

❌WeTransfer lacks encryption at rest, which is risky when sending high value media or datasets.

❌Google Drive and Dropbox often need extra configuration before they match enterprise transfer requirements.

Security & Compliance

✅Named User-Only Access – Only approved users with verified accounts can access transfers, reducing exposure.

✅Choose Your Storage Region – Select hosting locations that match both compliance demands and operational needs.

🟡Straightforward File Management – Upload, download, and track transfers without a complete document management suite.

❌No Ongoing Sync – Transfers are secure and one-off, rather than live mirrored.

File & Access Management

✅High-Volume Business Transfers – Send hefty media and datasets with strong encryption and precise audit logs, so delivery is provable and tidy.

✅Conversation in Context – Discuss large deliveries inside MX, right next to the files, which keeps instructions crisp and findable later on.

✅Branded Transfer Portals – Share through a portal that looks like yours, with your domain, logo, and colour palette at every step of the exchange.

🟡Edits Happen Beforehand – Prepare the final cut or build locally, then hand it over through MX for a secure, tracked send.

Collaboration

✅No File Size Limits – Transfer entire projects, raw media or data archives without restrictions. Google Drive stops at 750GB a day, while WeTransfer free users can only send up to 2GB.

✅Secure Upload Gateways – Create branded, encrypted portals for partners or clients to send you large assets. Consumer-grade services rarely provide this level of control.

❌No Permanent Storage – MX is tailored for quick, secure transfers, not for storing files indefinitely like Dropbox or OneDrive.

FAQs

1
Technology, Performance & Security
How does MX handle large file transfers compared to other platforms?

Optimised for Scale: MX is engineered to transfer files measuring multiple gigabytes without the slowdowns or file-size caps found in email or consumer platforms like WeTransfer or Dropbox. Transfers are streamlined by sharding, which distributes encrypted segments across multiple routes for faster delivery.

No Arbitrary Limits: Unlike services that restrict uploads to 2–10 GB, MX supports significantly larger transfers — making it suitable for industries handling CAD files, medical imaging, or media production.

See how MX compares in our guide: WeTransfer vs MX.

Does MX ensure large files remain secure throughout transfer?

Yes, Layered Protection: Every file — regardless of size — is encrypted with AES-256 and anonymised using MX’s ASR process (Anonymise, Shard, Restore). This ensures even multi-gigabyte transfers remain protected against interception.

No Open Links: Large files are never exposed via public URLs. Recipients must be explicitly authorised, and all actions are logged in an immutable audit trail.

Learn more on our blog about quantum-proof encryption and how it safeguards big data transfers.

Can MX transfer large files without storing them permanently?

Exchange, Not Storage: Large files are delivered securely and then removed once the transfer is complete. This avoids the common problem of oversized files clogging up cloud storage accounts or remaining online without oversight.

Why It Matters: Research shows 60% of files uploaded to sharing platforms are never accessed again [Varonis]. MX removes this risk by focusing exclusively on temporary, controlled exchange.

See our Features for how MX manages secure exchanges of all sizes.

How does MX maintain transfer speed for very large files?

Parallelised Transfers: MX splits large files into shards that move simultaneously across different channels. This reduces bottlenecks and ensures faster end-to-end delivery compared with single-stream uploads.

Consistent Reliability: Even during high traffic, MX avoids throttling. Each shard is encrypted and reassembled only at the recipient’s device, keeping performance stable while maintaining security.

For industries where delays cost money, this speed is crucial. Explore examples in our Case Studies.

Cost & Business Efficiency
Does MX reduce the cost of transferring very large files?

Yes, By Design: Unlike services that charge for bulk storage, MX’s model focuses on secure exchange. Large files are removed after delivery, avoiding storage bloat and reducing the expense of hosting terabytes of data unnecessarily.

Practical Savings: Businesses save not only on storage but also on bandwidth waste, since failed or repeated transfers are minimised by MX’s sharding approach.

Compare the difference in our analysis: Dropbox vs MX.

How does MX help avoid productivity losses from failed transfers?

Resilient Transfers: MX’s parallelised sharding ensures that if one route experiences issues, the rest continue unaffected. This is critical when dealing with gigabyte-scale projects where a single failure could waste hours.

Operational ROI: By reducing failed uploads and downtime, staff spend less time troubleshooting and more time focused on business outcomes.

Delays are expensive: a one-hour outage costs mid-size companies an average of $300,000 [IBM]. MX prevents downtime linked to large file handling.

Can MX support cross-organisation collaboration without adding extra licensing costs?

Yes, Controlled Sharing: With MX, large files can be securely exchanged across departments, clients, or partner organisations without every recipient needing a full suite license. Permissions are assigned at the file level, making collaboration cost-efficient.

Trusted Exchange: Since MX avoids public links, businesses can extend access confidently without exposing sensitive material.

For examples of inter-company workflows, visit our Case Studies.

Does MX help reduce compliance-related costs when handling large files?

Built-in Compliance Features: Audit logs, sovereignty controls, and expiry settings are included as standard. These remove the need for third-party add-ons or consultancy services, reducing long-term compliance expenses.

Risk Mitigation: By ensuring that large files are not permanently stored, MX reduces exposure to breaches — an important factor given the average global cost of a data breach now exceeds $4.88 million [Cobalt].

Learn more on our compliance pages: GDPR and ISO.

Does MX work alongside our existing tools?

Yes, Complementary Integration: MX is not designed to replace storage platforms but to add a secure transfer layer. It sits alongside tools such as project management systems or internal databases, providing a safe route for sharing large files externally.

API Connectivity: MX offers metadata integration, so audit logs and transfer records can feed into compliance systems or reporting dashboards.

For more detail, read our article on secure collaboration essentials.

What support is available for staff transferring large files?

Specialist Support: Businesses receive access to a responsive support team with expertise in security and compliance, not just general IT queries. This ensures that issues are resolved quickly, even when handling high-volume transfers.

Guides & Training: Onboarding resources, documentation, and optional live sessions ensure staff can confidently exchange files without reverting to insecure alternatives like email attachments or USB drives.

For help resources, see our FAQ hub or reach out directly via the Contact page.

Can MX be customised to reflect our brand when exchanging large files with clients?

Yes, White Labelling Options: MX allows companies to apply their own branding, including logos, colours, and domain mapping. This ensures that when clients receive large files, they interact with a secure portal that aligns with the organisation’s identity.

Why This Matters: A branded interface builds client confidence, demonstrating that file exchange is not outsourced to generic tools but managed securely within your own trusted environment.

Examples of branded setups can be found in our Case Studies.
