Send Files Securely with End-to-End Protection

01. How does MX ensure secure file sending?

MX ensures secure file sending by replacing risky, outdated sharing methods with a named-user system backed by quantum-secure encryption. Unlike tools that generate public links or rely on email attachments, MX delivers files directly to authorised recipients – ensuring visibility and control from start to finish.

Each transfer is logged in real time, giving you a verifiable chain of custody for every document. Whether you’re sending legal contracts, client records, or intellectual property, MX protects your data with enterprise-grade infrastructure that supports regulatory alignment.

Secure sending features include:

• Named-User Delivery Only: Prevents unauthorised access by ensuring files are only viewable by specific people.
• No Public Download Links: Eliminates the risk of link forwarding or unintended access.
• Quantum-Safe Encryption: Files are anonymised, split, and encrypted before transmission.
• Real-Time Notifications: Know exactly when your file has been accessed or downloaded. Learn more on our features page.

Research shows that 20% of broadly shared files contain regulated data, making secure delivery more than just a nice-to-have – it’s a compliance necessity.

MX gives businesses a trusted way to send files securely – ensuring every transfer is protected, accountable, and fully under your control.

02. Can I track who receives and accesses files on MX?

Yes – MX gives you full visibility into every file transaction, enabling you to track exactly who received, accessed, downloaded, or interacted with your files. Unlike traditional file-sharing tools that leave you in the dark after hitting “send,” MX offers real-time audit logging and user-level insights to ensure complete accountability.

All activity is linked to named users, so you’ll never have to guess who viewed what. This is especially valuable for businesses in regulated industries or those handling sensitive client data – where proving access control is essential for compliance and trust.

MX’s tracking features include:

• Named-User Verification: Files are only accessible to authenticated individuals – no public or anonymous access allowed.
• Real-Time Activity Logs: Monitor every file view, download, and interaction as it happens.
• Audit Trail Exports: Download access logs to support compliance efforts with ISO or GDPR standards.
• Automated Alerts: Receive notifications when files are accessed, helping you stay informed and in control.

According to Varonis, over 60% of organisations can’t track who accesses sensitive data – MX solves that problem with precision.

MX gives you the power to monitor every file sent – ensuring secure delivery, user accountability, and complete transparency across your business.

03. Does MX integrate with enterprise identity systems?

By all means! MX supports integration with enterprise identity systems, allowing organisations to streamline user management, enforce authentication policies, and maintain consistent access control across platforms. This makes MX a secure, scalable choice for businesses that already use tools like Active Directory (AD), Azure AD, Okta, or other Single Sign-On (SSO) providers.

By connecting MX to your existing identity infrastructure, you can automatically sync user roles, deactivate access in real-time, and apply internal policies to all file sharing activity – ensuring seamless compliance and centralised control.

Identity and authentication capabilities include:

• SSO & SAML Integration: Authenticate users via your corporate identity provider to maintain security consistency across tools.
• Role-Based Access Mapping: Align MX permissions with organisational structures like departments or job functions.
• Automated Deprovisioning: Remove access immediately when users leave the organisation or change roles.
• Audit Trails Linked to Enterprise IDs: Track all activity by user identity – supporting ISO and GDPR compliance frameworks.

As recommended by the UK National Cyber Security Centre (NCSC), integrating access management across cloud services is essential for maintaining strong digital identity practices – MX helps you achieve this out of the box.

MX integrates with your enterprise identity systems to give you full, centralised control over file access – reducing risk and simplifying compliance.

04. Does MX provide security compliance for file sending?

Yes – MX is designed to support full security and compliance for file sending, aligning with key frameworks like GDPR, the UK Data Protection Act, and ISO 27001. Every file sent through MX is protected with end-to-end encryption, access controls, and full audit logs – ensuring your organisation remains compliant with both industry regulations and internal policies.

Whether you’re transmitting sensitive personal data, financial reports, or confidential business documents, MX enables secure delivery to verified recipients only – without relying on public links or untracked email attachments.

Compliance-driven file sending features include:

• Quantum-Safe Encryption: All files are encrypted in transit and at rest using MX’s proprietary ASR (Anonymise, Shard, Restore) technology.
• Named-User Access: Only specified users can open shared files – ensuring identity-based compliance.
• Activity Logging: Every file event is tracked and timestamped for auditing purposes and regulatory reporting.
• Geographic Data Hosting: Choose your preferred data residency zone to meet local compliance obligations.

According to ICO guidance, organisations must ensure secure file transfer methods – MX provides a complete framework to meet those expectations without compromise.

MX gives you the confidence to send sensitive files securely – meeting compliance requirements with every transfer, every time.

05. What types of files can I send securely with MX?

With MX, you can securely send virtually any file type – from standard business documents to high-resolution media, software packages, and sensitive financial records. Whether you’re handling PDFs, spreadsheets, contracts, design files, DICOM images, or encrypted ZIP archives, MX applies the same quantum-safe encryption, named-user controls, and full tracking across the board.

This flexibility is critical for businesses across sectors like legal, finance, healthcare, and engineering, where different formats are used daily but all must remain protected during transmission.

Supported file types include (but are not limited to):

• Documents & Spreadsheets: PDF, DOCX, XLSX, ODT, CSV
• Media Files: MP4, MOV, AVI, WAV, JPEG, PNG, PSD
• Specialist Formats: CAD files (.dwg), DICOM (.dcm), XML, JSON, SQL backups
• Archives & Executables: ZIP, 7Z, RAR, EXE, MSI (with admin policies applied)

Every transfer is encrypted in transit and at rest, with access restricted to named recipients only. Files are never shared using public URLs or unsecured folders.
