How MX Stacks Up Against the Competition

Sensitive data deserves more than a locked folder. My MX Data stores it with continuous encryption, monitored access, and detailed logs so nothing is left exposed.

It’s strongest in Security & Compliance, File Control, Collaboration, and Data Preservation.

✅Quantum-Safe Storage - MX applies its ASR methodology to ensure stored files remain encrypted and inaccessible to anyone without permission. ℹ️ What does this mean?ASR (Anonymize, Shard, Restore) transforms files into anonymized shards, stores them in separate secure zones, and restores them only when requested by verified users, exceeding AES-256 standards.

✅Full Access History - Every file access, preview, and retrieval is logged in detail for security and compliance audits.

✅Supports HIPAA, CCPA & ISO 27001 - Built with role-based access and encryption suitable for regulated industries that need storage without risk.

❌WeTransfer is not designed for secure long-term storage and lacks encryption at rest.

❌Google Drive and Dropbox often fall short unless heavily configured for strict compliance.

Security & Compliance

✅Access Tied to Named Accounts – Only approved users can open stored files, reducing the risk of silent data drift.

✅Data Residency Control – Select the storage region that fits regulatory requirements and customer expectations, then keep it consistent.

🟡Straightforward Storage Tools – Upload, fetch, and audit activity with clean logs, minus the bloat of enterprise DMS features.

❌No Continuous Sync – Storage is stable and secure, not constantly mirrored between devices.

File Control

✅Confidential File Holding – Store sensitive data with encryption and activity logs for transparency.

✅File-Specific Messaging – Add clarifications or instructions directly to stored files.

✅Branded Access Environments – Maintain your logo and colors across all storage interactions.

🟡Changes Require Re-Upload – Update files externally before replacing them in the platform.

Collaboration

✅Transfer Without Size Caps – Send files of any scale, from small documents to terabyte-sized datasets. Google Drive limits uploads to 750GB/day, and WeTransfer free users are capped at 2GB.

✅Encrypted Storage for Transfers – Files are stored just long enough for secure delivery, using encrypted portals branded for your business. Consumer platforms can’t match this short-term security model.

❌Not for Long-Term Storage – MX focuses on short-term, secure holding until files are received, not indefinite archiving like Dropbox or OneDrive.

Data Preservation

How MX Protects Secure Data Storage

Stored data should be as guarded as data in motion. MX encrypts content at rest, ties access to named users and preserves years of auditable history. Quietly strong, rigorously traceable, built for long retention.

HIPAA
HIPAA rules do not stop once a file is uploaded. MX encrypts stored medical records and gives healthcare providers a detailed view of every access attempt, keeping compliance intact.
CCPA
CCPA obligations stretch into storage. MX enables businesses to keep personal files locked down with permissions and complete audit logs, demonstrating privacy throughout retention.
SOX
SOX compliance touches long term storage too. MX ensures financial records are encrypted at rest and that every access is recorded for accountability.
GLBA
GLBA puts responsibility on financial institutions to keep client data safe for as long as it exists. MX offers encryption and oversight that cover stored material as well as live transfers.
FISMA
FISMA reviews look closely at stored government data. MX provides encrypted storage and user tracking, ensuring agencies remain compliant throughout data retention cycles.
FERPA
FERPA requires schools to guard stored student records carefully. MX gives administrators tools to encrypt and limit access, so privacy is preserved.
ITAR
ITAR sensitive material does not lose its risk once archived. MX keeps it encrypted and geo restricted, helping defense contractors remain compliant over time.
CJIS
CJIS requirements apply equally to stored evidence. MX encrypts files and logs every retrieval, so agencies can maintain traceability years later.
IRS 1075
IRS 1075 obliges agencies and contractors to protect stored taxpayer files. MX secures them with encryption and access monitoring, reducing audit stress.
NIST 800-171
NIST 800-171 applies to storage environments handling CUI. MX encrypts data at rest, restricts permissions and captures audit logs, proving compliance.
Feature Description
🔒
Encryption at Rest, By Default
MX applies ASR with AES-256 to every stored object. Keys are scoped to the dataset which keeps content private through long retention windows.
👤
Named Access & Storage Permissions
Grant view or retrieve rights to specific people, teams or partners. Every access is tied to identity, IP and timestamp which removes guesswork later.
🛡️
Storage Compliance Alignment
Designed to support audits across common standards like HIPAA, ITAR, ISO and many more. MX pairs encryption with policy based access, retention choices and audit ready logs so reviewers see clear proof without heavy admin.
📜
Immutable Activity Ledger
Record views, edits and retrievals in a tamper evident log. Fast to search, simple to export, dependable during investigations or audits.
⏲️
Retention Policies & Legal Holds
Apply time boxed retention, pause deletion on demand and revoke access instantly. Reduces sprawl and keeps storage aligned to policy.
🌍
Data Residency & Geo Rules
Constrain stored data to approved regions with location aware controls. Helpful for ITAR restricted archives and locality clauses in contracts.
🧱
WORM & Version Integrity Options
Enable write once, read many behaviour for sensitive sets, lock versions during review and keep a traceable change history for integrity checks.
📦
Large Object Support without Limits
Store imaging, CAD and hefty datasets without imposed size caps. Encryption and tracking remain intact across very large objects.
🔑
SSO & Multi Factor Access to Stores
Connect your identity provider then require a second factor for high risk actions. Cuts account takeovers across administrators and partners.
🚫
No Public Links to Stored Files
Disable open URLs that drift beyond your perimeter. Access happens inside authenticated sessions with named recipients which keeps exposure low for archived material.

FAQs

1
Security, Sovereignty & Control
How is MX different from traditional cloud storage providers?

Focused on Exchange, Not Storage: Services like Google Drive or Dropbox are built to hold files indefinitely. MX works differently, keeping storage only as part of the delivery process and removing files once the transfer is complete.

Why That Matters: By limiting how long files stay online, MX lowers exposure to accidental leaks and abandoned data. This approach reflects the minimization principles embedded in leading compliance standards.

Does MX allow businesses to control where their data is stored?

Yes, Regional Control: MX lets organizations specify where file shards are kept. Sensitive material can remain within defined jurisdictions, which is critical for regulated sectors or firms managing cross-border data flow.

Example in Practice: A UK-based company can ensure shards remain in EU facilities, helping it comply with GDPR and the UK Data Protection Act without extra overhead.

Read more about sovereignty in our article on robust security features.

How does MX keep stored files secure during transfer?

Layered Encryption: While files are held for delivery, MX protects them with AES-256 encryption and its ASR process (Anonymize, Shard, Restore). Shards are anonymous and reassembled only on the recipient’s side.

Distributed Defense: Because no single server contains the full file, attackers can’t capture complete datasets even if one system is compromised.

Dig into the technical side in our blog on quantum-proof encryption.

Does MX prevent files from lingering online once they’re no longer needed?

Yes, Automatic Deletion: After a file is delivered, MX removes it from its servers. This sharply reduces the compliance and security risks associated with indefinite cloud storage.

Why It Matters: Studies show that 60% of files uploaded to cloud services are never accessed again [Varonis]. MX avoids this by making transfers temporary and controlled.

See how this approach supports regulatory alignment in our compliance overview.

Practical Business Benefits & Risk Reduction
Does MX help reduce costs linked to long-term cloud storage?

Yes, By Cutting Storage Waste: MX isn’t built to stack up years of forgotten backups. Files are removed after delivery, so companies aren’t stuck paying for terabytes of data that bring little or no value.

Real-World Effect: This keeps recurring storage bills lower while still giving teams a compliant and secure way to share sensitive material with clients or partners.

See how MX compares in WeTransfer vs MX.

How does MX reduce the risk of data breaches?

Less Time Online: Because files don’t sit around indefinitely, there’s less chance for attackers to find forgotten content on servers.

Quantum-Ready Defense: During transfer, every file is anonymized, sharded and encrypted. No single system ever contains the full dataset, making interception almost impossible.

With the average breach costing more than $4.88 million [Cobalt], trimming attack surfaces is a direct financial safeguard.

Can MX support compliance with regulations around data minimization?

Yes, Designed for Minimization: MX automatically deletes files once their exchange is complete, supporting GDPR Article 5(1)(e) and ISO 27001 requirements to keep personal data only as long as necessary.

Audit Evidence: Exportable logs show when files were uploaded, accessed and removed. These records make it easier to demonstrate good practice to auditors.

How does MX improve peace of mind for businesses handling sensitive data?

Defined Boundaries: Staff and clients know files are exchanged securely and do not linger online. This clarity reduces the temptation to fall back on risky habits like consumer drives or personal email.

Building Trust: Companies can show clients exactly how information is moved and protected, which helps reinforce professional confidence from the start.
