WeTransfer vs My MX Data: A Comprehensive Dive into Business File Sharing

WeTransfer is the crowd favourite for quick file sending. My MX Data is purpose built for secure file sharing for business, with named user exchanges, end to end audit trails, and a quantum secure patented methodology for long term confidentiality. Both encrypt, both are simple to start with. The difference shows up when files are sensitive, regulated, or need traceability for audits and contracts.

This comparison focuses on security architecture, controls, and the evidence you can produce later. It draws on public reviews of WeTransfer security practices and MX’s design for controlled B2B exchange.

What both services get right

For many day to day transfers, both platforms deliver a secure baseline.

• Encryption in transit and at rest: WeTransfer and MX use TLS for transport and AES 256 for storage.
• Account protection: Passwords and optional two factor authentication can be enabled.
• Availability at scale: Both run on ISO 27001 certified infrastructure with reliable performance.

Where the models diverge for business use

WeTransfer is built for ease and speed. My MX Data is built for controlled, auditable exchange between named users. The distinction matters when transfers involve client confidentials, regulated records, or intellectual property.

Security architecture: the key difference

Transport and storage encryption

Both services encrypt in transit with TLS and at rest with AES 256. Files on WeTransfer sit in ISO 27001 certified data centres, and the platform offers password protected links and optional two factor authentication. MX applies the same cryptographic strength, then adds system level controls for named users A model where a file can be sent only to specific accounts, not to anyone holding a public link.

End to end encryption and evidence

End to end encryption Data is encrypted on the sender side and decrypted only by the intended recipient, never exposed in plaintext on the service. is not provided by WeTransfer, meaning there are brief server side moments where content is decrypted between protection layers, as noted by independent reviews. MX is designed for end to end confidentiality with full audit trails and ASR which stands for Anonymise, Shard, Restore.

ASR is a quantum secure patented methodology that supports long term confidentiality. Combined with data sovereignty The ability to select where data is stored and processed to match legal or contractual requirements.

When to pick each service

Choose based on sensitivity, governance needs, and the audience you share with.

• WeTransfer fits when: You need to send large media or marketing files quickly to many recipients, link passwords and short expiry are sufficient, and you do not require end to end encryption or full chain of custody.
• My MX Data fits when: You must prove who accessed what, restrict sharing to named users, control residency, or protect client data and IP with end to end encryption and ASR. See encrypted file sharing and B2B secure exchange.

Bottom line for business teams

WeTransfer is great for quick distribution with helpful features in paid plans, including passwords, expiry selection, download tracking, and transfers up to 200 GB. It complies with GDPR and does not resell data. For mission critical confidentiality, the absence of end to end encryption and brief plaintext handling server side can be a limitation as external analyses point out. My MX Data focuses on secure, traceable handoffs with unlimited file size, ASR, and full auditability that facilitates stronger governance.
