FAQs
Your Top Questions Answered
01. What makes MX ideal for secure B2B file exchange?
MX is purpose-built to streamline B2B file exchange with top-tier security and control. Unlike general cloud storage platforms, MX focuses on precision – every file is only accessible by named users, eliminating the risks that come with open link-based sharing.
This is particularly vital for B2B exchanges, where confidential contracts, design files, legal documents, or client data are exchanged frequently across teams and organisations. MX facilitates these interactions while helping you meet compliance benchmarks like GDPR and UK DPA.
Core reasons MX stands out for secure B2B file transfers:
- Quantum-Secure Encryption: Uses our patented ASR method to protect data against modern and future cyber threats.
- Access Controls Per Partner: Assign and manage permissions per external company or department.
- Secure Project Communication: Collaborate with external partners using MX Conversations.
- Zero Public File Exposure: No download links – everything is tied to authenticated user identities.
B2B file exchange is a growing market, with over 42% of secure file transfers now occurring in B2B environments (Market.us). MX is designed to help businesses navigate that landscape with control and confidence.
For businesses handling sensitive transactions between partners or suppliers, MX offers a secure, auditable, and scalable solution that fits complex B2B workflows without compromise.
02. How does MX ensure data security for B2B transfers?
MX is engineered to protect B2B file transfers from start to finish using a layered security approach that combines quantum-safe encryption, strict user authentication, and real-time audit tracking. Every transfer is controlled, traceable, and designed to meet enterprise-level expectations.
Files are never sent via public links. Instead, transfers occur exclusively between named, verified users, eliminating the risk of unauthorised access – a critical requirement for industries like legal, tech, finance, and manufacturing.
Key B2B security features include:
- Quantum Secure Encryption: Files are anonymised, split into shards, and encrypted – protecting data in transit and at rest.
- Named User Permissions: Share only with specific individuals or teams – no guest links or untracked downloads.
- Geographic Data Hosting: Store data in approved regions to meet regulatory requirements across jurisdictions.
- Audit-Logged Transfers: Every access point is recorded and timestamped for compliance. Visit our features page for more details.
With B2B transfers accounting for 42% of the secure file transfer market, MX provides the infrastructure businesses need to operate safely across company lines.
MX ensures that B2B file exchanges stay secure, auditable, and compliant – no matter how complex or sensitive the data being transferred.
03. How can teams collaborate on shared files using MX?
MX enables secure B2B collaboration by combining encrypted file sharing, named-user access, and integrated messaging through MX Conversations. Rather than relying on email threads or external tools, teams and partners can exchange files and discuss them directly within the platform – while maintaining complete control over access and permissions.
This setup is ideal for businesses collaborating across departments or with external clients, suppliers, or partners. Every file is tied to a specific user, with activity logged in real-time – ensuring transparency, traceability, and accountability throughout the file lifecycle.
Collaboration-enhancing features include:
- MX Conversations: Secure, thread-based discussions that sit alongside file activity for clear project communication. Learn more on our enterprise collaboration page.
- Version-Aware Sharing: Ensure everyone accesses the latest version of a document, reducing confusion and duplication.
- Permission-Based Access: Grant view, download, or edit rights to specific team members or external partners.
- Real-Time Activity Tracking: Monitor who accessed, viewed, or shared each file, supporting audit and compliance efforts.
According to Gartner, 80% of workers now rely on collaboration tools – MX offers a secure alternative with data governance at its core.
With MX, your teams can collaborate efficiently across company lines – without compromising data security or compliance standards.
04. How does MX handle compliance for international B2B exchange?
MX is designed to simplify compliance in cross-border B2B data transfers by offering built-in support for regional regulations, data residency rules, and secure access control. Whether you’re working with clients in the UK, EU, or other global jurisdictions, MX ensures every file exchange is encrypted, auditable, and compliant with international standards such as GDPR, the UK Data Protection Act, and ISO 27001.
By eliminating public link sharing and enforcing named-user permissions, MX ensures your B2B file transfers meet legal expectations around privacy, traceability, and accountability – no matter where your partners are located.
Compliance-enabling features for international B2B workflows:
- Geo-Based Data Hosting: Choose where your data is stored to comply with jurisdiction-specific regulations and cross-border transfer rules.
- Audit-Ready Logs: Capture every access and transfer event for international compliance reporting.
- End-to-End Encryption: Ensure files are encrypted both in transit and at rest using quantum-safe protocols.
- Named-User Access Only: Control who can access data, regardless of location – preventing unauthorised sharing.
According to the European Data Protection Board, international data transfers must be governed by strong technical and organisational safeguards – MX delivers those safeguards by default.
MX enables global B2B collaboration without the compliance headaches – ensuring your file exchanges meet legal requirements, no matter where your partners are based.
05. Is there a file size limit for B2B file exchange on MX?
You’d be glad to hear there isn’t! MX does not impose file size limits for B2B file exchange. Our platform is built for high-volume, enterprise-grade transfers, allowing businesses to send and receive large files – securely and without delay. Whether you’re exchanging CAD drawings, media files, encrypted financial records, or bulk datasets, MX handles it all with speed, security, and compliance.
This is especially beneficial for industries like legal, manufacturing, and finance, where files regularly exceed the limits of traditional sharing tools. MX ensures that these exchanges remain fully auditable and protected, even at scale.
File exchange advantages for B2B teams include:
- No Upload/Download Limits: Transfer files of any size with no throttling or tier-based caps.
- Fast Transfer Protocols: MX optimises delivery speed based on location, bandwidth, and file size.
- Encryption at Every Stage: Quantum-safe encryption secures your large files during transit and at rest.
