Send Files Securely with Compliance Support

01. How does MX enable businesses to send files securely?

My MX Data provides a secure, streamlined solution for sending files safely within and outside your organization. With built-in encryption, audit trails, and customizable access controls, MX ensures that every file transfer remains private, compliant, and traceable.

Unlike traditional file-sharing methods such as email attachments or shared drives, MX encrypts every file during transfer with ASR (Anonymize, Shard, Restore) encryption, ensuring that sensitive data is protected in transit and at rest. Files are never shared via public URLs, reducing the risk of exposure.

Key features that make MX ideal for secure file sending:

• End-to-End Encryption: Every file is encrypted during upload, transit, and download using AES-256 encryption.
• Access Control: Share files only with verified, named users, and set permissions for download limits, expiry dates, and read-only access.
• Detailed Activity Logs: Monitor who accesses your files, when, and from which IP address with our built-in, real-time logging feature.
• Secure Delivery: Files are delivered directly to the recipient’s secure portal, eliminating the risks of open links and unauthorized access.
• MFA for Added Security: Enforce multi-factor authentication for every login, ensuring that only authorized users can access or send files.

Research from StrongDM reveals that 61% of SMBs are targeted by cyberattacks – making secure file transfer tools like MX essential for minimizing risk and ensuring business continuity.

02. Are there restrictions on file types or sizes when sending via MX?

Absolutely not! My MX Data supports all file types and enforces no hard size limits when sending files. Whether you’re transferring high-resolution videos, CAD drawings, legal archives, or encrypted financial documents, MX is optimized to handle it without delay or compression.

Unlike platforms such as WeTransfer (with a 2GB free limit) or email clients that block certain file types (like .exe or .zip), MX is purpose-built for secure, enterprise-grade handoffs. This means your team can confidently share any format or file size needed to keep projects moving securely and efficiently.

MX’s advanced transfer capabilities include:

• Unlimited File Sizes: Send terabytes of data if needed – ideal for media production, engineering, or medical imaging.
• All Common File Types Supported: From PDFs, DOCX, and XLSX to ZIP, MOV, and proprietary formats.
• Encrypted Transfers: Every file is secured using AES-256 and quantum-resilient ASR encryption.
• Resumable Uploads: Transfers resume automatically if interrupted, ensuring reliable delivery over weak connections.
• Custom Send Pages: Brand your sending interface with your logo, colors, and messaging for a professional touch.

This flexibility is part of why MX is favored by businesses in fast-paced industries like architecture, healthcare, and finance – where time-sensitive data exchange must be seamless and secure.

03. Can I confirm delivery or receipt of a file after sending?

Yes – My MX Data provides full visibility into each file’s journey from sender to recipient. Every time a file is accessed, downloaded, or even attempted to be opened, it is logged with a timestamp, IP address, and user ID for complete transparency and peace of mind.

MX goes beyond standard delivery notifications by offering:

• Real-time delivery tracking: Know when a recipient opens or downloads a file, and from which device or location.
• Download verification receipts: Confirm successful handoffs, especially useful for regulatory workflows.
• Failed access alerts: Get notified of unsuccessful or unauthorized attempts to view your files.
• Persistent audit trail: Maintain compliance by preserving a permanent record of every file transaction.

This level of traceability helps ensure financial institutions, law firms, and other regulated industries meet industry-specific obligations and prove secure communication with clients and partners.

04. Can files be sent securely to people outside my organization?

Yes, My MX Data is designed to facilitate secure file transfers both within and outside your organization. With MX, you can easily send files to external clients, partners, or vendors, ensuring that every transfer meets the highest security standards.

Key features that make external file sharing secure include:

• End-to-End Encryption: All files are encrypted from the moment they leave your system until they reach the recipient, ensuring they are protected during transit.
• Access Control: You control who can access the files by setting permissions and expiration dates for each transfer.
• Audit Trails: Keep track of who opened, downloaded, or interacted with the file to ensure compliance and transparency.

Whether you’re sending sensitive business documents, legal contracts, or financial data, MX provides the security and compliance features needed to protect your information. For a detailed look at how this works, check out our secure file sharing for accountants page.

MX ensures peace of mind by giving you full control over every file sent, even when working with external parties.

05. Does MX let me confirm who downloaded each file and when?

It does indeed! We provide precise visibility into every file interaction, including who downloaded each file and the exact time it occurred. This audit-grade tracking is embedded into every secure transfer, giving you peace of mind that your sensitive data has reached the intended recipient – and no one else.

Each download event is recorded within your MX dashboard, and you can export these logs for compliance reviews, internal audits, or client reporting. This is especially useful for regulated industries or contractual obligations that require proof of delivery.

• Verified Access Logs: See the name and identity of every person who accesses a file.
• Timestamped Download History: Each download is recorded with accurate time and date metadata.
• Non-Repudiation Support: Detailed records help ensure that access cannot be denied or disputed later.
• Email and IP Logging: For additional traceability, you can also log associated emails and IP addresses.

With the secure file transfer market projected to reach $3.63 billion by 2029, tools like MX that offer strong confirmation and auditability features are becoming essential – not just preferred. MX empowers your organization to demonstrate exactly what happened, and when, for every file you send.

Whether you’re sending legal contracts, financial records, or sensitive project files, MX ensures you know exactly who accessed what – no guesswork required.
