How MX Stacks Up Against the Competition

While WeTransfer gets files to their destination, My MX Data gets them there with locked encryption, controlled access and auditable logs so you can prove compliance at any point.

This is shown in Security & Compliance, File Control, Collaboration and Large File Delivery.

✅Client-Ready Quantum Protection – MX uses its ASR methodology to keep client exchanges private, even against emerging quantum risks. ℹ️ What does this mean?ASR (Anonymise, Shard, Restore) turns files into anonymised shards, transports them across isolated secure routes, and restores them only for verified clients, going beyond standard AES-256 defence.

✅Auditable Client Access – Every view, comment, and download is time stamped for dependable records during engagements.

✅Aligned with GDPR, UK DPA & ISO 27001 – Upholds strict permissions and encryption in client communications.

❌WeTransfer stores files unencrypted at rest, which undermines confidentiality with clients.

❌Google Drive and Dropbox need policy hardening to satisfy regulated client workflows.

Security & Compliance

✅Controlled Named User Access – Sharing is limited to authorised accounts, keeping files out of unauthorised hands.

✅Regional Data Storage Choice – Pick where your data resides to stay compliant with legal obligations.

🟡Basic File Features – Uploading, downloading, and tracking are included, without full DMS tools.

❌No Live Sync – Built for secure transactions, not constant updates.

File & Access Management

✅Confidential Client Transfers – Share proposals, reports, and private records with robust encryption and a clean audit trail for each interaction.

✅On-Platform Messaging – Keep client questions and clarifications attached to the relevant files, cutting out scattershot email threads.

✅Client-Facing Branding – Your clients use a portal that carries your identity, which reinforces trust and keeps the experience consistent end to end.

🟡No Live Co-Authoring – Finalise content in your preferred editor, then send via MX for secure, verifiable delivery.

Collaboration

✅Unlimited File Sizes – Share any amount of data without hitting an upload ceiling. By contrast, Google Drive caps at 750GB per day, and WeTransfer free stops at 2GB.

✅Encrypted, Client-Facing Portals – Receive sensitive information through secure, custom-branded links. Standard consumer tools don’t offer this professional intake option.

❌Not Intended for Archiving – MX is optimised for transfer workflows rather than acting as a long-term storage service like Dropbox or OneDrive.
