Patented ASR methodology

Anonymize. Shard. Restore.
Protection that does not depend on one complete file.

Encryption remains essential. MX adds a separate control by removing identifying context, dividing the data into shards and distributing those shards across selected locations. An intercepted fragment is not a usable copy of the original file.

Anonymize

MX separates identifying context from the payload as the file enters the platform, so an individual fragment does not carry useful meaning by itself.

Shard

The anonymized data is split into shards and distributed across storage locations you select. AES-256 encryption protects each stage in transit and at rest.

Restore

MX restores the shards for the authorized, named recipient after the required identity and access checks. The handoff stays tied to a person, not a public link.

Built with longer-term exposure in mind. Separating sensitive data into anonymized fragments reduces reliance on a single encrypted object and gives security teams another control for files that may remain valuable for years.

For exchanges that need tighter control

Everyday platforms handle routine collaboration.
MX handles sensitive handoffs.

Dropbox, Google Drive and WeTransfer can work well for routine storage, collaboration and quick transfers. MX is intended for files that need verified recipients, clear access conditions and a defensible record of activity.

Patented ASR protection

ASR anonymizes and shards data before delivery, adding a separate protective control alongside AES-256 encryption.

Detailed exchange records

Views, uploads, downloads and exchanges are recorded with timestamps, giving security, compliance and audit teams a clearer account of what happened.

Supports US compliance programs

Named access, expiration settings, encryption and audit records can support controls used in HIPAA, CCPA, ITAR, SOX and NIST SP 800-171 programs.

Consumer transfer tools prioritize speed and convenience

That can leave regulated or business-critical exchanges without the access rules, retention controls or records the workflow calls for.

General cloud platforms cover broader use cases

Sensitive handoffs may require extra configuration, governance and user discipline when they run through a general-purpose platform.

Verified named-user access

Files move between authorized individuals. MX does not use public file links, which reduces the chance of an exchange being forwarded outside the intended group.

Configurable data locations

Choose where shards are stored to support contractual terms, data residency decisions and internal information-governance policies.

Purpose-built B2B exchange

Send, receive and track sensitive files without adding a full document management platform to the workflow.

No background sync by design

MX is designed for deliberate file handoffs rather than background synchronization or live co-authoring.

Controlled exchange between businesses

Create a consistent handoff process for sensitive files moving within your organization or to customers, suppliers and partners.

Conversations linked to the exchange

Threaded discussions stay connected to the related file activity, so instructions and decisions do not disappear into a separate email chain.

White-labeled portals

Use your own domain, logo and colors to give clients and partners a consistent experience under your organization's identity.

Fits around the tools your teams already use

Keep creating files in Word, Excel, CAD and other specialist tools, then use MX for the controlled exchange.

No file size limit

General-purpose services often apply transfer limits. MX can move engineering datasets, diagnostic imaging, media and full project archives without a file size limit.

Secure branded upload portals

Collect sensitive files through a branded upload portal with clearer control over who can submit information and where it goes next.

Exchange without defaulting to permanent storage

MX is built for secure exchange rather than indefinite document storage, helping organizations reduce unnecessary retention after a handoff is complete.

Clear evidence for every exchange

See who did what,
and when it happened.

When an auditor, customer or internal team asks about a file, MX provides a time-stamped history of uploads, views, downloads, messages and transfers.

Activity recorded as it happens

Uploads, views, downloads and messages appear in the audit trail as the exchange progresses.

User and IP context

Review activity for internal users and external recipients, including the network context available for each event.

MFA, limits and expiration controls

Set identity checks, download limits and expiration dates that match the sensitivity and purpose of the file.

Patented ASR methodology

ASR separates and distributes data while AES-256 protects it in transit and at rest.

Named recipient controls

Files are exchanged with authorized individuals, with identity checks and detailed activity records supporting the handoff.

No public file links

Public links and anonymous shared URLs are disabled by design.

Immediate activity records

Views, downloads, uploads and messages are recorded as they occur.

Secure upload portals

Collect sensitive documents through a controlled, branded upload process.

No file size limit

Exchange bulk datasets, diagnostic images and high-resolution files without a file size limit.
