FAQs
Your Top Questions Answered
01. How does MX protect client file exchanges?
MX protects client file exchanges by removing the common vulnerabilities found in link-based sharing tools. Every file sent through MX is encrypted, tracked, and bound to a specific, named user – ensuring your clients’ data remains private, controlled, and fully auditable.
This is especially critical for businesses in finance, healthcare, law, and consulting, where client trust hinges on confidentiality and compliance. MX not only secures the files themselves, but also secures the entire file exchange process – from upload to download – with enterprise-grade infrastructure.
Core protections include:
- No Public Links: All files are shared directly with authenticated recipients – there’s zero risk of accidental exposure.
- Quantum-Secure Encryption: Files are anonymised, split into shards, and encrypted to prevent interception.
- Branded Upload Portals: Clients can send you sensitive documents securely through a branded, encrypted portal.
- Comprehensive Audit Trails: Every file interaction is logged for compliance and peace of mind. Learn more on our features page.
According to Varonis, over 800 domains interact with shared company files on average – making secure client-specific exchange an essential best practice.
MX ensures every client file transfer is handled with the same care, security, and control your reputation depends on.
02. Can clients upload documents securely to MX?
Definitely! MX provides a dedicated secure upload portal that allows your clients to send documents directly to your organisation without compromising confidentiality or control. Unlike email attachments or open cloud folders, MX’s client upload process is encrypted, branded, and fully traceable.
This feature is ideal for industries that require a high degree of trust – such as accounting, law, healthcare, and consulting. Clients don’t need an MX account to upload; they simply use your branded portal, ensuring ease of use while maintaining strict security standards.
Benefits of client-side uploads via MX:
- Encrypted from the Start: Files are protected using quantum-safe encryption the moment they’re submitted.
- No Account Required: Clients can upload securely without signing in – reducing friction and technical barriers.
- Branded Experience: Present a professional portal under your domain, aligned with your brand.
- Audit Logging for All Uploads: Every client upload is logged, timestamped, and tied to their identity where applicable.
As secure communication becomes a baseline expectation, platforms like MX help you meet it while enhancing professionalism. You can explore this further on our secure upload portal page.
With MX, your clients can upload sensitive documents in seconds – knowing they’re protected by enterprise-grade encryption and secure delivery protocols.
03. Does MX support messaging alongside file sharing?
Without a doubt! MX includes built-in, secure messaging through a feature called MX Conversations, which allows users to communicate directly alongside file exchanges. This makes it easy to provide context, instructions, or feedback on documents – without relying on insecure email threads or disjointed communication tools.
MX Conversations are particularly useful for professionals working with clients, such as accountants, legal advisors, or consultants, where timely, traceable discussions about specific files are critical. Every message is tied to a secure, auditable environment – keeping communication and compliance tightly integrated.
Messaging features that enhance file sharing include:
- Secure, Threaded Conversations: Keep communications tied to specific file transfers or clients – ideal for project clarity and revision history.
- No Third-Party Tools Required: Eliminate the need for external chat apps or unencrypted emails.
- Audit-Ready Messaging Logs: Conversations are stored securely and time-stamped, supporting regulatory compliance and dispute resolution.
- Client Collaboration Enabled: External users can participate in conversations using secure portals – ensuring a seamless experience.
As highlighted in NCSC guidelines, secure collaboration tools must integrate communication and data control – MX meets that requirement by design.
MX makes client collaboration simple and secure by combining file sharing and messaging – keeping everything in one encrypted, compliant environment.
04. Can I monitor activity on files shared with clients?
Yes – MX provides full visibility into all file activity, so you can monitor how, when, and by whom your shared files are accessed. Whether you’re sharing sensitive contracts, financial documents, or reports with clients, MX keeps a secure, real-time audit trail of every interaction – allowing you to stay informed and in control at all times.
This level of transparency is critical for building client trust, supporting regulatory compliance, and preventing unauthorised file usage. From views and downloads to expired access and revoked permissions, every action is logged and traceable.
Monitoring tools available with MX include:
- Named-User Activity Tracking: See who accessed a file, when, and from where – eliminating guesswork.
- Audit Trail Logs: Access downloadable records for compliance reporting and client transparency. Explore more on our ISO compliance page.
- Access Notifications: Get alerts when a file is opened or downloaded, helping you track engagement and usage patterns.
- Revocable Permissions: Revoke access in real time if necessary – without affecting other shared content.
MX’s activity monitoring aligns with secure collaboration best practices outlined by the UK National Cyber Security Centre – helping you manage risk and reinforce accountability in client interactions.
MX empowers you to share files with clients confidently – while maintaining complete visibility and control over every step of the process.
05. How does MX ensure client data stays protected during handoffs?
MX secures every client file handoff with a layered approach that combines quantum-safe encryption, named-user access, and real-time tracking. Whether you’re transferring contracts, sensitive financial data, or identity documents, MX ensures that only the intended recipient can access the file – no public links, no uncontrolled downloads.
This is especially vital during client onboarding, legal document review, or regulated exchanges, where confidentiality and control are critical. Every interaction is logged, and permissions can be revoked instantly – even after a file has been shared.
Handoff security features include:
- Named-User Permissions: Share files only with verified users – each action is linked to an authenticated identity.
- End-to-End Encryption: Files are encrypted in transit and at rest using quantum-resistant algorithms.
- Activity Logging: Track when a client opens, downloads, or re-shares a file – supporting compliance and audit readiness.
- Portal Access Control: Use branded, secure upload/download portals with expiry dates and download limits per client.
MX’s safeguards align with best practices highlighted in the CSO Online guide to secure client communication.
With MX, every client file handoff is controlled, encrypted, and monitored – giving you and your clients peace of mind at every stage of the exchange.
