Quantum secure patented methodology

Anonymise. Shard. Restore.
Additional protection for sensitive files.

Traditional encryption protects data as a complete file. MX adds another layer by anonymising the data and dividing it into separate shards, reducing exposure if an individual fragment is intercepted.

Anonymise

Identifying context is separated from the file as it enters MX, helping prevent an individual data fragment from revealing meaningful information on its own.

Shard

The anonymised data is divided into shards and distributed across selected storage locations, with AES-256 encryption protecting data in transit and at rest.

Restore

The shards are restored only for the authorised, named recipient, creating a controlled handoff rather than an open link that can be forwarded.

Designed for evolving threats. By separating sensitive data into anonymised fragments, the ASR methodology adds a further layer of protection and supports a more future-focused security posture.

A different role to everyday sharing tools

Everyday platforms have their place.
MX is built for controlled exchange.

Dropbox, Drive and WeTransfer are useful for everyday storage, collaboration and convenient transfers. MX is designed for exchanges where named access, traceability and governance matter.

Patented quantum secure methodology

The ASR methodology anonymises and shards data, adding another layer of protection alongside conventional encryption.

End-to-end audit trails

Every interaction is recorded and time-stamped, providing clear evidence for clients, auditors and internal governance teams.

Supports GDPR, UK DPA and ISO 27001 objectives

Access controls, expiry settings and detailed audit logs help organisations demonstrate appropriate controls around sensitive exchanges.

Consumer transfer tools prioritise convenience

They may not provide the access controls, retention options or evidence required for sensitive business workflows.

General cloud platforms serve broader use cases

Additional configuration and governance may be needed when files require tightly controlled, auditable handoffs.

Named-user access

Files move between authorised, verified individuals. Public file links are disabled, reducing the risk of uncontrolled forwarding.

Data location options

Select where data shards are stored to support regional, contractual and information governance requirements.

Purpose-built file exchange

Upload, exchange and track sensitive files without introducing the complexity of a full document management system.

No real-time sync by design

MX is designed for controlled file handoffs rather than background synchronisation or live co-authoring.

Controlled B2B exchange

Secure handoffs with detailed audit records for sensitive exchanges inside and outside your organisation.

MX Conversations built in

Secure, threaded discussions remain connected to the relevant file activity, keeping context within the controlled exchange.

White-labelled portals

Use your own domain, logo and colours to give clients and partners a consistent, professionally governed experience.

Works alongside authoring tools

Create and edit files in Word, Excel, CAD or your preferred tools, then exchange them securely through MX.

Unlimited file sizes

File allowances vary across general-purpose services. MX supports large engineering datasets, media, imaging and project archives without a file size limit.

Secure branded collection portals

Receive sensitive files through a secure, branded intake process with clearer control over how information enters your organisation.

Exchange rather than permanent storage

MX is designed for secure exchange rather than permanent document storage, helping organisations reduce unnecessary retention of sensitive files.

Total traceability

A clear record of
every file action.

When a client, auditor or internal stakeholder asks what happened to a file, MX provides a time-stamped record of views, downloads, uploads and exchanges.

Real-time activity logs

Views, downloads, uploads and messages are recorded as the exchange takes place.

Access and IP tracking

Review activity across internal users and the external parties involved in each exchange.

MFA and expiry controls

Use identity verification, download limits and expiry dates to keep access proportionate and controlled.
