How MX Stacks Up Against the Competition

Law firms need to move case files securely. My MX Data delivers confidential transfer channels, access control, and tamper-proof logs to protect client information.

It excels in Security & Compliance, File Control, Collaboration, and Legal Data Handling.

✅Confidentiality at Every Stage - MX applies its ASR methodology to safeguard case files, contracts, and discovery documents. ℹ️ What does this mean?ASR (Anonymize, Shard, Restore) anonymizes files, splits them into encrypted shards, moves them through separate secure routes, and restores them only for approved recipients, going beyond AES-256 protection.

✅Precise Access Controls - Restricts document access to assigned individuals only, with clear permission logs.

✅Supports HIPAA, CCPA, ISO 27001 & ABA confidentiality rules - Provides audit-ready encryption for sensitive legal work.

❌WeTransfer stores files without encryption-at-rest, unsuitable for privileged legal data.

❌Google Drive and Dropbox can expose metadata unless additional configurations are applied.

Legal Data Security

✅Access Limited to Named Users – Legal case files are shared only with identified recipients, keeping confidentiality intact.

✅Select Hosting Region – Choose where legal documents are stored to stay aligned with jurisdiction-specific requirements.

🟡Straightforward Management – Upload, download, and check the activity trail without managing an entire DMS platform.

❌No Continuous Sync – Purpose-built for case-by-case sharing, not constant replication across devices.

Legal File Control

✅Confidential Client Exchanges – Transfer case files, contracts, and evidence with encryption and controlled access rights.

✅Linked Conversations – Attach secure notes or clarifications directly to each file so critical context stays with the document.

✅Firm-Branded Portals – Maintain a polished, recognizable environment that reflects your legal practice’s identity.

🟡No Live Draft Editing – Documents must be finalized externally before secure sharing.

Law Firm Collaboration

✅Transfer Case Files of Any Size – Whether it’s evidence videos or entire case archives, move them without limits. Google Drive stops at 750GB/day, and WeTransfer free caps at 2GB.

✅Secure, Client-Facing Portals – Receive confidential documents through encrypted, branded intake pages that meet legal privacy expectations.

❌Not for Long-Term Document Storage – MX specializes in secure transfer, not permanent archiving like Dropbox or OneDrive.

FAQs

1
Security, Confidentiality & Professional Use
How does MX keep client documents secure during transfers?

End-to-End Encryption: Every document is encrypted before it leaves the sender and remains protected in transit. MX uses its ASR method (Anonymize, Shard, Restore) so no single server holds the full file.

Controlled Access: Files are delivered only to named recipients, with identity checks built in. This avoids the risks of forwarding or open link sharing that are common with consumer tools.

Learn more about the technical process on our Quantum-Proof Encryption page.

Does MX support attorney-client privilege requirements?

Yes, Designed for Confidentiality: MX prevents files from lingering in inboxes or uncontrolled folders. Documents are deleted automatically once received, reducing unnecessary retention.

Why It Matters: By limiting exposure, firms demonstrate that they’re protecting privileged material in line with professional conduct rules and client expectations.

Explore more safeguards in our blog on secure collaboration.

Can MX handle sensitive case files of large size?

Yes, No File Size Limits: Whether it’s e-discovery data, scanned evidence, or video depositions, MX handles large files quickly and securely without artificial caps.

Industry Relevance: This makes MX especially useful for litigation teams that often share bulky files which email systems can’t manage reliably.

See more detail on our Large File Sharing page.

How does MX help law firms meet regulatory obligations?

Compliance Support: MX generates immutable logs for every transfer, showing who accessed what and when. These records can help firms demonstrate adherence to frameworks like GDPR, ISO 27001, or state bar data security guidelines.

Practical Benefit: Instead of manual record-keeping, audit trails are automatic, saving time while reducing risk during reviews.

Efficiency, Client Service & Firm Reputation
How does MX save time for legal teams managing documents?

Streamlined Workflow: Instead of juggling emails, FTP servers, or courier deliveries, all file sharing takes place in one secure portal. Lawyers and staff spend less time tracking down documents and more time on client work.

Automatic Records: Each transfer is logged automatically, so there’s no need to manually document who received which file and when.

Read more about reducing admin overhead in our blog: Accelerating File Transfers.

Will clients find it easy to receive and upload files through MX?

Yes, Built for Accessibility: Clients don’t need to install software or create complex accounts. They simply use a clean, branded interface to send or receive files securely.

Professional Experience: A dedicated portal reinforces trust, showing clients that their confidential material isn’t being passed through consumer-grade tools.

See real-world examples in our Case Studies.

Can MX improve collaboration across departments or external counsel?

Yes, Designed for Collaboration: MX makes it simple to share files securely with co-counsel, expert witnesses, or clients. Each recipient is verified by name, ensuring documents only reach the right people.

Cross-Firm Advantage: For cases involving multiple parties, MX avoids the chaos of different platforms and delivers a single controlled environment for document exchange.

How does MX strengthen a law firm’s reputation with clients?
