Patented ASR methodology
Anonymise. Shard. Restore.
MX adds a layer around conventional encryption by separating identifying context, dividing protected data into fragments and restoring the exchange only for the intended recipient.
Shard
Divide protected data into separate fragments while AES-256 safeguards information in transit and at rest.
Restore
Reconstruct the data for the authorised named recipient instead of exposing a reusable public download link.
A different role to everyday sharing tools
Everyday platforms have their place. MX is built for controlled exchange.
Use general storage and collaboration tools for everyday work. Use MX when the handoff itself needs named access, traceability, expiry controls and clearer evidence around sensitive business data.
Explore all features →- Unlimited file-size transfers
- Multi-factor authentication
- Configurable access and expiry
- Full transaction audit trail
- External customer and supplier workflows
- Browser-based access with no on-site installation
Total traceability
A clear record of every file action.
Keep a time-stamped history around the exchange so teams can answer who received a file, when activity happened and how access was controlled.
Activity evidenceViews, downloads, uploads and exchange activity remain connected to the transaction.
Recipient accountabilityNamed-user access and MFA support deliberate handoffs rather than open forwarding.
Expiry controlsLimit how long data remains available and how many downloads are permitted.
Large-file readyKeep high-volume technical and business data inside the same governed route.
Governance support
Controls and evidence for stronger information governance.
MX does not make an organisation compliant on its own. It provides access controls, encryption and auditable exchange records that can support the organisation’s wider security and compliance programme.

Common questions
What teams usually want to know before they start.
Is there a maximum file size?
MX is designed for large-file exchange and does not impose a normal business file-size ceiling on transfers.
Do recipients need software installed?
No. Recipients use a browser-based workflow, so a local application or on-site installation is not required.
Can access expire?
Yes. Availability and permitted downloads can be controlled so an exchange does not remain open indefinitely.
Is activity recorded?
Yes. Transaction history provides a record around the exchange, including recipient activity and key file actions.
Can we use MFA?
Yes. Multi-factor authentication can add an additional identity check around recipient access.
Can we discuss SSO or a larger deployment?
Yes. Use the enterprise demo to discuss identity, administration, deployment scale and your external collaboration model.
