Secure File Sharing for Business

Quantum secure patented methodology

Anonymise. Shard. Restore.
Your data, unreadable in transit.

Conventional platforms encrypt a file and hope the key holds. MX goes further: files never travel as a single readable object, so there is nothing whole to intercept.

Anonymise

Every file is stripped of identifying context the moment it enters MX. Names, metadata and content are decoupled, so the data itself reveals nothing about its origin or purpose.

Shard

The anonymised data is split into shards and distributed across separate storage regions of your choosing, layered on top of AES-256. No single location ever holds a usable file.

Restore

Shards reassemble only at the destination, and only for the named, verified recipient. Not for a link. Not for an inbox. A person your business has authorised.

Built for what comes next. Because intercepted shards are anonymised fragments rather than encrypted wholes, the ASR methodology is designed to remain resilient even against future quantum computing threats.

MX vs the usual suspects

Dropbox stores. WeTransfer sends.
MX protects.

General-purpose tools were built for convenience. MX was built for businesses where a misdirected file is a board-level incident. See where the difference shows.

Quantum-resilient by design

The ASR methodology anonymises and shards data before it moves, protection that conventional encryption alone does not offer.

End-to-end audit trails

Every interaction is recorded and time-stamped, giving you a defensible record for regulators and clients alike.

Facilitates GDPR, UK DPA and ISO 27001

Access controls, expiry settings and immutable logs give your compliance team the guardrails they need.

WeTransfer lacks encryption at rest

Which makes it a poor fit for anything genuinely sensitive.

Drive and Dropbox need heavy configuration

Enterprise-grade compliance is an add-on project, not a default.

Named user access only

Files move between authorised, verified individuals. There are no public links to forward, leak or scrape.

Data sovereignty selection

Choose exactly which regions hold your shards to align with legal and contractual obligations.

Deliberately lean file management

Upload, exchange and track. MX is not a bloated DMS, and that is the point.

No real-time sync

MX is built for secure handoffs, not silent background syncing that spreads copies everywhere.

High-trust B2B exchange

Encrypted handoffs with audit-ready logs, ideal for sensitive collaboration inside and outside your organisation.

MX Conversations built in

Secure, threaded discussion tied directly to file activity, so context never drifts into unsecured inboxes.

Fully white-labelled portals

Your domain, your logo, your colours. Clients never feel handed off to a third-party tool.

No live co-authoring

Draft in Word, Excel or CAD, then hand off the final file securely through MX.

Unlimited file sizes

Drive caps daily uploads and WeTransfer limits free users to 2GB. MX moves engineering datasets, media and imaging without restriction.

Secure branded collection portals

Receive sensitive files from clients through encrypted, branded intake, something consumer tools simply do not offer.

No long-term cloud archive

MX moves files securely and then removes them. Nothing sensitive lingers in the cloud waiting to be breached.

Total traceability

Every file action,
on the record.

When a client asks who accessed a document, you should not have to guess. MX records every view, download and exchange with a time-stamped, immutable entry.

Real-time activity logs

Views, downloads, uploads and messages, captured the moment they happen.

Access and IP tracking

Monitor activity across your team and every external party you exchange with.

MFA and expiry controls

Identity verification on login, plus download limits and expiry dates you define.

Teams that cannot afford a leak
choose MX.

The audit history gives us a reliable answer when a client asks who accessed something. It feels secure, well judged and easy enough for the whole team to use.

HB

Hannah BrooksOperations Director

It isn't bloated with features we'll never use, yet the security is strong enough for serious compliance checks. Staff began using it straight away without training.

HC

Helen C.Operations Manager, Manufacturing

The version control and audit trail tools were quite helpful for project management, making it easy to monitor changes and retrieve past data.

AZ

The platform feels precise, not overloaded, and that gave staff confidence right away. It's rare to find something both highly secure and easy to live with day to day.

Mainstream platforms are built for storage and convenience. MX is built exclusively for secure file sharing for business: controlled, auditable exchanges between named users, protected by the quantum secure patented methodology (ASR). There are no public links, no lingering copies, and every action is logged. See our full Dropbox vs MX comparison.

No platform can guarantee compliance, and you should be wary of any that claims to. MX facilitates compliance with GDPR, the UK DPA and ISO 27001 through strict access controls, expiry settings, data sovereignty options and immutable audit logs, giving your team the practical guardrails to meet its obligations. Explore the details in our Features section.

MX is not a storage system. Files are held only for the purpose of delivery and are removed once exchanged, so sensitive material never lingers in the cloud. Transfers can also carry expiry dates and download limits, closing the door once the file has served its purpose.

There is no file size limit. Engineering schematics, medical imaging datasets, broadcast media, full project archives: MX transfers them quickly and securely, across organisations and borders, while every action remains logged.

Most organisations exchange their first files within hours. There is nothing to install: MX runs in the browser, colleagues are added as named users, and expiry and permission policies take minutes to apply. Enterprise clients also get a dedicated account manager.

Yes. MX can be fully white-labelled with your logo, colours and even your own subdomain, so clients experience every exchange under your governance rather than a third-party tool. Start with a free trial to see it in action.
