How MX Stacks Up Against the Competition

A lot of platforms will move business files quickly. My MX Data moves them with controlled encryption, detailed tracking, and strict access permissions so every transfer is secure and verifiable.

Its strengths are clear in Security & Compliance, File Control, Collaboration, and Large File Handling.

✅Quantum-Ready Encryption - MX uses its ASR methodology to keep B2B exchanges private against current and emerging threats. ℹ️ What does this mean?ASR (Anonymize, Shard, Restore) converts files into anonymized shards, routes them over separate secure channels, and restores them only for authorized partners, offering stronger protection than standard AES-256.

✅End-to-End Audit Trails - Every transfer, view, and receipt is timestamped so you can prove who accessed what, and when.

✅Supports HIPAA, CCPA & ISO 27001 - Delivers encryption and permission controls that fit strict B2B requirements.

❌WeTransfer lacks encryption at rest, which leaves sensitive agreements exposed after upload.

❌Google Drive and Dropbox often require added configuration before meeting enterprise B2B policies.

B2B File Security

✅Named User Access – Only approved accounts can send or receive files, which reduces the chance of accidental exposure or misuse.

✅Select Data Hosting Location – Store files in the region that best matches your regulatory and operational needs.

🟡Core File Management Tools – Upload, download, and review transfer activity without the heavier framework of a full document management system.

❌No Continuous Synchronization – Optimized for secure, controlled handoffs rather than ongoing background updates.

B2B File Management

✅Business-Grade Transfers – Exchange sensitive contracts, reports, and project files with encryption in place and clear, verifiable logs for every transaction.

✅Conversations In Context – Discuss file details directly within the platform so messages stay tied to the correct activity, not lost in email chains.

✅Branded Partner Portals – Deliver files in an environment that uses your logo, colors, and domain, helping reinforce trust with each exchange.

🟡No Live Document Editing – Finalize work in your chosen editor before uploading it through MX.

B2B Collaboration

✅No Transfer Size Caps – Send a single high-resolution file or an entire multi-terabyte dataset without running into upload limits. Google Drive stops at 750GB per day, while WeTransfer free users are capped at 2GB.

✅Encrypted Business Portals – Branded intake pages let partners and clients share confidential data directly and securely. Consumer-grade services rarely offer this controlled exchange process.

❌No Long-Term Archiving – MX is focused on secure, efficient transfers rather than permanent cloud storage like Dropbox or OneDrive.

B2B File Transfer

How MX Enables B2B Secure File Exchange

Cross company sharing should be quick, careful and provable. MX encrypts every handoff, binds access to named recipients and records a crisp audit trail partners can trust.

HIPAA
Patient data often moves between business associates. MX applies encryption and tracks each handoff so HIPAA expectations are met during partner to partner exchanges.
CCPA
CCPA’s focus on consumer privacy extends to B2B activity. MX lets companies set granular permissions and show clear evidence of file handling which reassures partners and clients alike.
SOX
SOX requires financial records shared across firms to remain trustworthy. MX encrypts each file and keeps detailed transfer logs so accountability follows the data.
GLBA
Under GLBA, institutions must secure financial data even when exchanging files with third parties. MX provides encryption plus visibility which protects client information throughout the chain.
FISMA
Federal contractors exchanging data across organizations face FISMA demands. MX enforces strict access rules and provides logs robust enough to back up compliance claims.
FERPA
FERPA applies when universities or vendors trade student records. MX keeps those files encrypted and only opens them to verified users on a per case basis.
ITAR
ITAR controlled designs cannot be allowed to wander. MX applies geo restrictions and encrypted pathways which keeps technical data inside permitted territories.
CJIS
Agencies exchanging criminal justice information can use MX to enforce tight access, capture full audit logs and maintain CJIS standards without slowing collaboration.
IRS 1075
Taxpayer records shared between agencies or contractors require IRS 1075 compliance. MX encrypts files and logs every interaction which creates a transparent record.
NIST 800-171
NIST 800-171 compliance for B2B exchanges is supported by MX through encrypted handoffs, role based controls and audit ready reporting.
Feature Description
🔒
Partner-to-Partner Encryption
MX pairs ASR with AES-256 on every exchange. Keys are scoped to the transfer which keeps content private across vendors, clients and subcontractors.
👤
Named Recipients Across Orgs
Bind decryption to real people, not links. Each open is tied to identity, IP and timestamp which makes ownership obvious during reviews.
🛡️
B2B Compliance Alignment
Supports audits across familiar standards like HIPAA, ITAR, ISO and many more. MX blends encryption, permissioning, retention choices and audit ready logs so partners see proof fast.
🤝
Segmented Partner Workspaces
Fence projects by company and role. Prevent cross project sprawl and keep each partner’s view clean, narrow and accountable.
📩
Delivery Proof & Read Receipts
Know a package arrived, was opened and by whom. Resolve disputes quickly and hand auditors a neat storyline of what happened.
🌍
Geo Rules & Region Locks
Constrain access to approved locations with location aware checks. Helpful for export controlled designs and regional data promises in contracts.
📦
Large Payload Ready
Move CAD, media and multi gigabyte datasets without imposed size caps. Integrity checks validate every chunk so heavy files arrive intact and private.
🔗
API & SFTP Bridges
Automate exchanges from ERPs or case systems. Keep encryption, access checks and audit logs intact even when the send is machine driven.
🧾
Third-Party Risk Evidence Packs
Export who accessed what, why they had permission and the outcome. Share with vendor management teams to shorten reviews and renewals.
⏲️
Expiry Windows & Remote Revocation
Time box access, revoke in one click and shut down stale sessions. Circulation stays tight around sensitive partner content year round.
🚫
No Public Links by Design
Block open URLs that drift outside your perimeter. Access flows through authenticated sessions and named recipients which keeps exposure low across firms.

FAQs

1
Technology & Credibility
Why is MX suited for B2B secure file exchange?

MX is purpose-built for B2B secure file exchange, not as a long-term cloud drive. Every transfer uses our quantum secure patented methodology. Files are anonymised, split into shards and restored only for the intended recipient, removing the risk of documents lingering online.

US businesses choose MX because it facilitates compliance with strict frameworks like HIPAA, CCPA and NIST 800-171. Adoption is already high in sectors such as finance, healthcare and law, where about 60 to 70 percent of organisations use enterprise-grade encryption solutions [Statista].

Unlike consumer platforms, MX records a complete audit trail for each file handoff. Explore these capabilities further on our Features page or browse Case Studies to see how US organisations already use MX for regulated transfers.

Can MX manage large data volumes between partner firms?

Yes, MX supports unlimited file size transfers. Whether you are exchanging CAD blueprints, imaging datasets or detailed regulatory reports, transfers remain fast and fully encrypted.

  • Ultra-Fast Sharing: Large files move quickly without losing confidentiality.
  • No Arbitrary Caps: MX imposes no artificial size limits, unlike many mainstream tools.
  • Cross-Organisation Ready: Optimised for repeated exchanges between verified partner domains.

The secure file transfer market is projected to grow from $2.5 billion in 2025 to $3.26 billion by 2028 [GlobeNewswire], showing just how critical large-scale secure exchanges have become.

How does MX reduce compliance risk in cross-company transfers?

Cross-company file sharing is often the weakest point in data governance. MX reduces exposure with its named-user access model. Files can’t be forwarded or accessed outside of authorised recipients, which provides traceability and accountability.

MX facilitates compliance rather than guaranteeing it, but features like end-to-end encryption, expiry controls and detailed audit logs give organisations a structured way to demonstrate alignment with US frameworks such as SOX, GLBA, FISMA and CJIS. For more, see our HIPAA page or ISO Compliance guide.

Does MX provide audit trails for B2B exchanges?

Yes. MX automatically generates comprehensive audit trails. Every upload, download and recipient action is logged with timestamps and location details, so businesses can easily evidence how data was handled.

These logs can be exported for internal governance or regulatory reviews, reducing reliance on costly add-on monitoring tools. Many firms find MX replaces the patchwork of transfer and compliance software they used before. Learn more in our blog on robust security features.

Efficiency & Business Value
How does secure B2B sharing improve operational efficiency?

Traditional file sharing is often plagued by size caps, unreliable links, or security doubts that slow down projects. MX eliminates these barriers, allowing firms to focus on outcomes rather than technical hurdles. By replacing email attachments and unsecured drives, teams report saving hours every week on administration alone.

  • Streamlined Workflow: Files flow directly to approved users without detours.
  • Lower Risk of Rework: Version control reduces duplication and miscommunication.
  • Better Partner Trust: Clients and vendors receive files confidently, avoiding back-and-forth clarifications.

Evidence shows that 39% of all business data uploaded to the cloud is used primarily for file sharing (6sense), underlining the value of making those exchanges efficient rather than cumbersome.

Can MX be tailored to different industry requirements?

Yes, MX provides industry-specific flexibility. Through its metadata APIs and governance settings, the platform adapts to fields as varied as engineering, healthcare and finance. For instance, healthcare providers can align file exchange with HIPAA frameworks, while manufacturers can control the distribution of CAD schematics with expiry dates.

Our Case Studies illustrate how organisations across sectors configure MX to suit their workflows. In practice, this avoids the need for separate file transfer solutions per department, reducing cost and complexity.

3
Setup, Support & Integration
Is MX simple for non-technical external partners to use?

Yes. MX is intentionally easy to use, even for partners with little technical background. Invited users receive secure credentials and can immediately log in. From there, sending or receiving files feels as familiar as adding an email attachment, only with far stronger protection.

This ease of use is important in B2B environments where partners vary in technical expertise. By reducing the learning curve, MX keeps collaboration moving without creating delays. You can start a free trial to see first-hand how simple it is for external users.

What onboarding support is available for new B2B partners?

MX provides dedicated onboarding support to make sure new partners and teams get started smoothly. Clear setup resources, direct access to our Help Center and responsive customer support are included as standard. Enterprise clients can also assign an MX account manager to oversee onboarding across multiple departments or third parties.

  • Guided Setup: Step-by-step instructions designed for both administrators and end users.
  • Live Support: Email and ticketing with quick turnaround times from compliance-aware specialists.
  • Ongoing Training: Refresher content and updated resources to keep users confident long-term.
