Encrypted file exchange
End to end encrypted file sharing, with evidence attached
Protect sensitive files with AES-256 encryption in transit and at rest, then add named-recipient access, configurable controls and a detailed record around the exchange.

End to end encrypted file sharing needs more than a cipher
For organisations comparing end-to-end encrypted file sharingA security model intended to protect data from sender to recipient. Implementations and key handling can differ, so the complete design still needs to be assessed. services, the practical question is not only whether a file is encrypted. It is whether the complete exchange is controlled, traceable and explainable afterwards.
- Can a sharing link be forwarded beyond the intended recipient?
- Does access remain available after the business need has passed?
- Can your team evidence who opened, downloaded or replaced a file?
- Can the process be defended to a client, auditor, DPO or risk committee?
A controlled exchange in MX
Security controls applied to the complete handoff.
Encrypted file transfer, strengthened by ASR.
MX combines established AES-256The 256-bit variant of the Advanced Encryption Standard, commonly used to encrypt data while stored and while being transferred. protection with a patented quantum secure methodology built to reduce the exposure created when a complete, identifiable file is held or moved as one object.
AES-256 encryption
Files are encrypted in transit and at rest, helping protect sensitive information while it moves through the exchange and while it is held for delivery.
- Protects file content during transfer
- Protects data while stored for exchange
- Applied automatically, without users managing encryption keys
Quantum secure patented methodology
ASR anonymises the data, divides it into shards and restores it only within the authorised exchange process. A shard is not a complete usable file in isolation.
- Separates file identity from the protected data
- Distributes shards instead of storing one complete object
- Built to strengthen long-term data protection
Careful terminology matters: MX does not claim that technology can eliminate security risk. Its layered approach is built to give organisations stronger control, resilience and evidence around sensitive file exchanges.
How the quantum secure patented methodology works.
ASRMX's Anonymise, Shard and Restore methodology: identifying context is separated, protected data is divided, and it is restored through the authorised exchange process. adds a further layer to secure encrypted file sharing by changing how protected data is identified, separated and restored within the exchange process.
Anonymise
Identifying context is separated from the protected data. This reduces the usefulness of the data if viewed outside the authorised process.
Shard
The anonymised data is divided into multiple shards. No single shard represents the complete file, supporting a more distributed security model.
Restore
The protected data is restored through the authorised exchange process so the named recipient can access the file in its usable form.
What ASR is built to achieve: an additional layer of protection beyond conventional file sharing, helping organisations prepare for evolving security threats without adding manual steps for everyday users.
The controls that make an exchange defensible.
Encryption protects the file. Governance controls help your organisation explain who received it, what they could do with it and what happened next.
Named-user access
Share files with identified users instead of relying on public or anonymously forwarded links.
Detailed audit trails
Maintain a record of file activity that can help support internal reviews, client questions and audit evidence.
Expiry and permissions
Limit how long a file remains available and apply controls appropriate to the sensitivity of the exchange.
Data sovereignty options
Enterprise configurations can help support data sovereigntyRequirements concerning the countries or legal jurisdictions in which data is stored, processed or controlled. requirements around where protected data shards are held.
Large file transfer
Move large engineering, media and project files without falling back to fragmented consumer tools or email attachments.
Explore large file sharingConversations in context
Keep secure discussion connected to the file activity, reducing the need to separate evidence across email chains.
What happens when you send an encrypted file.
The security process runs around a familiar user journey, helping people share sensitive files without having to become encryption specialists.
Choose the recipient
Select a named user, instead of generating
an open link that can be passed on.
Apply the controls
Set expiry, permissions and any exchange requirements appropriate to the file.
Protect and transfer
AES-256 and ASR are applied within the platform as the file is prepared for delivery.
Track the activity
Review the audit trail and retain evidence of the exchange if questions arise later.
Where MX fits alongside everyday file-sharing tools.
Email, cloud drives and general transfer services remain useful. MX is for the exchanges where stronger identity, traceability and governance are required.
Fast and familiar, but difficult to govern at scale.
Email works well for routine communication. Sensitive attachments can become harder to recall, expire or evidence once sent.
- Convenient for everyday correspondence
- Recipient mistakes can be difficult to reverse
- Attachment versions and downstream copies can be hard to track
Excellent for storage, syncing and collaborative work.
Cloud drives are built to help teams store and collaborate on documents. Sensitive external handoffs may require careful configuration and ongoing permission management.
- Strong for long-term storage and co-authoring
- Shared folders can accumulate access over time
- External sharing governance depends heavily on configuration
Simple delivery, with less certainty over identity.
Link-based transfer services are useful for quick sends. Where a link can be forwarded, the organisation may have less confidence that only the intended person accessed the file.
- Low-friction transfer for non-sensitive files
- A link can become detached from the original recipient
- Audit evidence may be limited or plan-dependent
Built for controlled, auditable file exchange.
MX focuses on secure handoffs between named users. It is not intended to replace every storage or collaboration platform in your organisation.
- Named-user access with no public file links
- Encryption, ASR, expiry settings and permissions
- Detailed audit trails for accountable data movement
The right platform depends on the use case. MX is most valuable where the sensitivity of the file makes a controlled, evidence-led exchange process important.
For files that cannot be handled casually.
MX supports organisations that need to protect confidential client, supplier, operational or intellectual-property data as it moves beyond the immediate team.
Legal and professional services
Exchange case files, contracts and client records through a controlled process with named access and traceable activity.

Public and regulated services
Strengthen governance around sensitive records and inter-organisation file transfers where accountability is central.
Explore public-sector sharingUse MX alongside the tools your team already knows.
MX is not a full document management system and it is not a real-time co-authoring platform. It provides a more controlled route for the file exchanges that ordinary collaboration tools were not built to govern on their own.
- Create and collaborate in Microsoft 365, Google Workspace, CAD or specialist business systems.
- Move the final or sensitive file through MX when the handoff needs stronger control.
- Use audit evidence and transaction metadataContext recorded about an exchange, such as participants, timestamps, status and file activity, instead of the file content itself. to support governance processes.
