Your Top Questions Answered
01. What are the benefits of using MX’s secure file upload portal?
MX’s secure file upload portal allows businesses to receive sensitive documents from clients, suppliers, or partners without compromising control or security. Unlike email attachments or public upload links, our portals are fully encrypted, branded to your business, and restricted to named user access.
This means you know exactly who uploaded what, when it happened, and where it came from – making MX ideal for companies that handle financial records, contracts, healthcare files, or regulated data.

02. Is the upload portal customisable and compliant?
Yes – MX’s secure upload portal is both fully customisable and designed to support compliance with major data protection regulations like GDPR, the UK Data Protection Act, and ISO 27001. You can tailor the portal to reflect your brand identity – adding your company logo, colours, and custom domain – while benefiting from a secure, auditable file submission experience.
The portal ensures files are never submitted via insecure channels like email. Instead, every upload is encrypted using MX’s patented ASR (Anonymise, Shard, Restore) methodology and logged with full traceability. This makes it ideal for industries like legal, finance, and healthcare, where secure intake of sensitive files is critical.

MX’s upload portal combines brand customisation with strict compliance controls – giving your business a secure, professional way to receive sensitive documents with full transparency and trust.
03. Can I set file expiration dates or download limits for clients?
By all means! MX gives you full control over how long files remain accessible and how many times they can be downloaded. This is especially useful for time-sensitive exchanges, contract submissions, or document handovers that require limited availability and traceable access.
You can set file-level rules that automatically expire access after a specific date or after a predefined number of downloads – helping you stay compliant with retention policies and reduce the risk of unnecessary file exposure.
File control features include:
- Expiry Dates: Automatically revoke file access after a set time frame, useful for project milestones or regulatory deadlines.
- Download Limits: Cap the number of downloads to prevent file oversharing or misuse by external users.
- Revocation on Demand: Instantly revoke access to any file at any time – even before the expiry date.
- Audit Logging: Monitor who downloaded the file and how many times – supporting GDPR and ISO 27001 audit requirements.
These controls align with best practices outlined by the UK National Cyber Security Centre for time-bound access and controlled sharing in cloud environments.
With MX, you can give clients access to the right files for the right amount of time – while maintaining full control, compliance, and peace of mind.
04. Can MX’s portal notify me when new files are uploaded?
Yes – MX’s secure upload portal includes automatic notifications that alert you the moment a file is uploaded by a client, partner, or team member. This real-time feedback loop ensures your team never misses an important document and can act promptly on time-sensitive submissions like contracts, financials, or legal paperwork.

Notification and visibility features include:
- Instant Upload Alerts: Receive email or in-platform notifications when a user submits a file through your branded portal.
