How MX Stacks Up Against the Competition

Uploading sensitive documents should be straightforward but fully secure. My MX Data offers encrypted upload portals, access control, and time-limited links to keep transfers private.

It works best in Security & Compliance, File Control, Collaboration, and Client Submission Tools.

✅Client-Friendly Secure Uploads - MX provides an ASR-powered upload portal where files are protected from the moment they leave the sender’s device. ℹ️ What does this mean?ASR (Anonymize, Shard, Restore) instantly anonymizes and shards files, sends them via independent secure paths, and reconstructs them only for authorized users, surpassing AES-256 protection.

✅Track Every Submission - Every file submission is logged with sender, time, and IP data for security teams.

✅Complies with HIPAA, CCPA & ISO 27001 - Uses encryption and permission controls for all inbound file handling.

❌WeTransfer offers no secure client portal for ongoing submissions or projects.

❌Google Drive and Dropbox portals lack built-in encryption-at-rest for external users.

Secure Uploads Security & Compliance

✅Uploads Restricted to Named Users – Only identified senders and recipients can submit or retrieve files through the portal, which keeps submissions orderly and accountable.

✅Pick a Storage Location – Assign the portal to a specific data region so inbound files stay under the right jurisdiction from the start.

🟡Clear, Simple Controls – Upload, download, and view submission logs in one place, without extra document system complexity riding along.

❌No Live Sync – The portal is optimized for secure submissions and receipts, not persistent synchronization.

File Management for Secure Uploads

✅Private Upload Points – Give clients and partners a safe way to send you files directly.

✅Upload-Linked Messaging – Request details or confirmations alongside the file submission.

✅Custom-Branded Portals – Maintain your organization’s look and feel throughout the upload process.

🟡No In-Portal Editing – Files must be prepared before submission.

Collaboration via Upload Portals

✅No Restrictions on Upload Size – Clients can send anything from a few images to multi-gigabyte archives without limits. Google Drive stops at 750GB/day, and WeTransfer free halts at 2GB.

✅Encrypted Custom Portals – Provide a secure, branded upload point for clients and partners. This type of controlled intake is rarely found in consumer tools.

❌No Cloud Archive Function – MX focuses on short-term, secure file movement rather than long-term storage like Dropbox or OneDrive.

Client Submission Tools

How MX Secure Upload Portals support Compliance

Collecting files from clients should feel simple and be safe. MX encrypts every upload on entry, ties access to named staff and writes a clean audit trail from the first byte. Intake stays tidy, risk stays low, evidence stays ready.

HIPAA
Healthcare teams often need clients to upload records. MX gives them a portal that encrypts everything on entry, meeting HIPAA while keeping the process simple for patients.
CCPA
CCPA puts pressure on companies collecting consumer data. MX’s upload portal limits who can see each file and keeps detailed logs, so businesses can prove privacy is respected.
SOX
SOX compliance is not just about internal systems. MX captures and encrypts every file a client uploads which builds a transparent record auditors can rely on.
GLBA
Banks and advisory firms gathering client files face GLBA requirements. MX secures uploads with encryption and access history which ensures sensitive data enters the system responsibly.
FISMA
Federal agencies use portals too, and FISMA applies. MX locks down uploaded files with encryption, permissions and audit trails fit for inspection.
FERPA
Schools gathering student records digitally fall under FERPA. MX encrypts those uploads and ensures files are only visible to designated staff.
ITAR
Defense suppliers need upload portals that respect ITAR. MX encrypts files and applies geo controls which blocks data from slipping beyond authorized zones.
CJIS
Law enforcement agencies often require evidence uploads. MX captures full logs, restricts access and encrypts each file which aligns with CJIS rules.
IRS 1075
Tax documents sent through an upload portal must meet IRS 1075. MX encrypts them instantly and logs every access which makes audits less painful.
NIST 800-171
Contractors tied to NIST 800-171 need portals that prove compliance. MX enforces encryption, controlled access and logs from the first upload.
Feature Description
🔒
Encrypt on Entry, Every Time
Uploads are encrypted the moment they land using MX ASR with AES-256. Keys are scoped to the submission which keeps sensitive content private from the start.
👤
Submitter Identity & Consent Capture
Collect a verified identity, capture consent and bind the file to the person who sent it. Clear ownership helps during audits and disputes.
🛡️
Compliance Alignment for Intake
Supports common frameworks like HIPAA, ITAR, ISO and many more. MX pairs encryption with policy based access, retention choices and audit ready logs so reviewers see proof fast.
📥
Branded Portals & Smart Requests
Send a checklist, track what arrived and nudge for missing items. Clients see a clean branded portal which cuts confusion and back and forth.
📩
Delivery Receipts & Acknowledgements
Confirm a file was received, opened and reviewed. Each event lands on the record with identity, IP and timestamp.
🗂️
Review Queues & Approvals
Route uploads to the right team, request approval and lock the decision to the audit trail. Work moves quickly without losing control.
📦
Large Uploads without Fuss
Handle imaging, CAD and hefty datasets with steady throughput. Encryption and tracking remain intact regardless of size.
🌍
Geo Rules & Residency Controls
Constrain visibility to approved regions using location aware checks. Useful for ITAR restricted submissions and regional contracts.
⏲️
Expiry Windows & Instant Revocation
Set time boxed access for reviewers, revoke in one click and prevent stale links from lingering. Keeps circulation tight around sensitive uploads.
👁️
Organisation Wide Activity Ledger
Search a precise history of submissions, views and downloads with identity, IP and timestamp. Fast answers for incidents and scheduled reviews.
🔑
SSO & Multi Factor for Staff Access
Connect your identity provider then require a second factor for higher risk actions. That blend reduces account takeovers across busy teams and vendors.
🚫
No Public Bucket Links
Turn off open URLs that leak beyond your perimeter. Access happens inside authenticated sessions with named recipients which keeps exposure low.

FAQs

1
Security, Access & Professional Use
What makes our portal safer than clients sending files by email?

Email Creates Risk: Attachments can be forwarded, intercepted or left in inboxes for years. MX replaces this with a secure upload portal where files are encrypted, logged, and delivered only to the intended recipient.

Professional Safeguards: Every upload is tied to a verified user, tracked with audit logs, and automatically removed after delivery. This avoids the long-term exposure that email storage often creates.

For comparison, see our guide on WeTransfer vs MX.

Can clients without technical skills use our portal?

Yes, Built for Accessibility: The interface is clean and intuitive. Clients drag and drop files into the portal without needing to install software or create accounts.

Why It Matters: In industries like law, finance and healthcare, clients want processes to be simple while still knowing their information is handled with strict confidentiality.

See how businesses apply MX in practice by reviewing our Case Studies.

How does MX protect sensitive files once they are uploaded?

Encrypted & Sharded: Files are secured with AES-256 encryption and MX’s ASR process (Anonymize, Shard, Restore). No server ever contains the entire file, and reconstruction only happens at the receiving endpoint.

Automatic Removal: After delivery, files are deleted from MX’s environment, reducing the chance of dormant data being exposed.

Dive deeper into the technical side in our article on quantum-proof encryption.

Does an MX portal support compliance requirements for regulated industries?

Yes, Compliance-Focused Design: The portal provides immutable logs and expiry controls that help support HIPAA, SOX, GLBA and NIST 800-171. MX doesn’t issue compliance certification, but it facilitates adherence by supplying the technical guardrails auditors expect.

Industry Alignment: Whether handling patient records, tax documents or case files, MX allows organizations to show regulators and clients that sensitive material is exchanged responsibly.

2
Efficiency & Client Experience
How does MX's portal save time compared to manual document collection?

Centralized Process: Instead of chasing files through endless email threads or relying on USB drives, client uploads land in one secure and traceable location. Staff spend less time digging through inboxes and more time focused on actual client work.

Instant Availability: As soon as a file is uploaded, it becomes accessible to authorized team members. For smaller firms handling dozens of clients each week, this speed can make the difference between delays and smooth delivery.

See more about boosting workflow efficiency in our blog: Accelerating File Transfers.

Will clients find it easy to upload documents?

Yes, Built for Ease: The portal is designed with drag-and-drop simplicity and clear prompts. Clients don’t have to create accounts or download apps, which keeps the process straightforward.

Client Reassurance: A branded, secure upload page signals professionalism and care. It shows clients their information is handled in a controlled environment, not left vulnerable in standard email systems.

See practical examples in our case studies.

Can our portal handle large files from clients?

Yes, No Arbitrary Limits: Whether it’s a 20MB tax file or a multi-gigabyte imaging dataset, clients can upload without hitting restrictive caps. Every transfer is encrypted and processed consistently, regardless of file size.

Why That Matters: Industries like healthcare, law and architecture often exchange files that are far too large for standard email. MX ensures these transfers happen quickly and securely.

3
Branding & Ongoing Support
Can the portal be customized to match our brand identity?

Yes, With White Labeling: Businesses can add their own logo, colors and even use a branded subdomain. This keeps the experience consistent for clients and helps build trust by making the upload environment feel like a natural extension of your company.

Professional Impact: A customized portal shows credibility and reduces hesitation from clients who might otherwise question if a link is legitimate.

See the different branding options in our Features section.

What support is available once I've signed up?

Responsive Help: MX offers direct customer support plus a detailed knowledge base so businesses can solve issues without delay.

For Growing Teams: Optional onboarding for new hires and refresher training for existing staff help keep processes consistent as your organization expands.

Always Available: Whether it’s setup guidance, best practices or compliance-related questions, support is there so you’re never left managing the system alone.
