My MX Data Security Features: How Your Files Are Protected

Security claims can blur together until each control is examined on its own. This guide looks at how MX handles identity, access, evidence, encryption and added data protection.

In this guide

A sensitive business file can pass through several systems before it reaches the person who needs it. The sender prepares the package, a link or attachment carries it outside the organisation, the recipient authenticates, and a local copy may remain after the work is complete.

Strong data sharing gives the organisation control across that full journey. My MX Data is designed to make the exchange identifiable, protected and reviewable, without making routine delivery needlessly awkward.

Security architecture Protect the file, verify the recipient and preserve the evidence.

MX combines access controls, encryption, activity records and configurable exchange conditions. Each control answers a different question, from who should receive the information to what the organisation can prove afterwards.

This layered design matters because no single feature settles every risk. Encryption cannot confirm the recipient, authentication cannot set an appropriate access period, and an audit trail cannot correct a poor recipient choice.

Unstructured exchange

Convenience creates unanswered questions

A public link can be forwarded outside the intended group.
The sender may not know whether the recipient downloaded the file.
Access can remain available after the task or project has ended.
Instructions, comments and later versions become separated.
MX exchange

The handoff has an identity and a history

The sender selects approved or named recipients.
Access conditions can reflect the sensitivity and purpose.
Recipient activity is recorded against the transaction.
Related files and conversations can remain connected.
Access controlStart with the person, not the link

Named recipients create a clearer security boundary

A transfer becomes easier to govern when the organisation can identify the intended recipient. MX allows files to be directed to approved or named people rather than relying on an unrestricted public link. This supports accountability across customers, suppliers, contractors and project partners.

Multi-factor authentication adds another identity check before access is granted. A password on its own can be exposed, reused or guessed. MFA reduces dependence on that one credential by requiring an additional verification step. It does not remove every identity risk, but it strengthens the point where a recipient proves who they are.

Permission-based access and user roles separate ordinary participation from administration. Relevant MX configurations can also support single sign-on, custom domains and wider user management, alongside prompt onboarding and offboarding.

Data protectionUse several methods for different risks

Encryption forms one layer of the MX security model

MX uses AES-256 encryption as part of its security controls. Encryption helps protect information during relevant stages of storage and transfer by making the underlying data unreadable without the required cryptographic process. Its value is substantial, although it should sit beside access control, identity checks, endpoint security and sensible handling by the recipient.

Businesses comparing approaches to encrypted file sharing should look beyond the encryption label. They should also ask how recipients are identified, what administrators can configure, how activity is recorded and whether access can be withdrawn or allowed to expire.

Additional protectionAnonymise, separate and restore

ASR changes how a sensitive file is retained

ASR stands for Anonymise, Shard and Restore. It is a patented methodology used by MX to provide an additional layer of protection for sensitive information. ASR is separate from standard encryption and should not be treated as another name for it.

Anonymise Remove recognisable context The data is transformed so the underlying business content is not retained in a directly recognisable form.
Restore Rebuild for authorised access The required information is securely restored when the authorised recipient needs to use it.

The transformed data is separated into multiple protected shards, which prevents a single readable file from being retained in one place. An isolated shard does not contain the complete document or enough usable context to reconstruct it independently. The full information is restored for authorised access through the defined process.

ASR may be relevant for highly sensitive intellectual property, technical data or confidential records. It should be assessed alongside the wider system and workflow, rather than treated as an absolute guarantee.

AccountabilityKnow what happened after the send button

Audit records turn an exchange into reviewable evidence

Many file-sharing problems become visible only when somebody asks a basic question: did the recipient receive the correct file? MX records activity associated with the exchange, which may include uploads, access, downloads, comments, time information, user information and relevant IP details.

That record helps administrators identify pending transactions, investigate activity and prepare evidence for reviews. Notifications can also surface downloads, comments, expiring access and actions still waiting.

Named recipients
Restrict the intended exchange to approved people rather than an anonymous audience.
Clearer accountability
MFA
Add another identity check before a recipient reaches protected information.
Stronger access confidence
AES-256
Protect data cryptographically during relevant stages of storage and transfer.
Reduced readable exposure
Expiry
Prevent temporary business access from remaining open indefinitely.
Smaller access window
Audit trails
Retain a structured record of activity across the transaction.
Reviewable evidence
ASR
Anonymise and separate data before restoring it for authorised use.
Additional data protection
Operational controlKeep files, releases and conversations connected

Security is easier to maintain when the workflow remains usable

People will find another route when an approved system cannot handle the size, pace or structure of their work. MX supports very large transfers without arbitrary file-size restrictions, helping teams exchange CAD data, media, software packages and large document sets without splitting the delivery across several tools.

MX Conversations keeps comments and instructions beside the files being discussed. Linked Transactions connect follow-up exchanges while retaining the identity of each transaction. Recipient groups reduce repetitive setup for established customers, suppliers or project teams.

MX Distribute supports controlled release to multiple recipients. An organisation can publish the current package, add recipients, monitor uptake and see who is still pending. This is useful for software releases, engineering data and other information where the same approved version must reach several external parties. Businesses managing complex exchanges can explore the wider benefits of a secure B2B data exchange platform.

Platform controls support governance, but they do not replace it.

MX can provide security controls, administrative oversight and audit evidence that help organisations support wider compliance objectives. Compliance still depends on policies, configuration, legal basis, staff behaviour, endpoint security, retention, training, monitoring and incident response.

Mainstream cloud platforms can suit storage, synchronisation and live collaboration. MX serves the controlled external handoff, where the sender needs to identify the recipient, define availability and review activity.

A strong exchange process gives routine sending and receiving enough structure for people to work quickly without giving up accountability.
