GDPR Compliant File Sharing for Sensitive Data

01. How does MX help my business comply with GDPR?

MX is designed to support businesses in aligning with the General Data Protection Regulation (GDPR) by providing the controls, visibility, and encryption necessary to safeguard personal data during digital exchanges. While no platform can guarantee GDPR compliance on its own, MX facilitates many of the technical and organisational measures outlined in the regulation.

One of the key ways MX assists is by ensuring that all file transfers are traceable, encrypted, and tightly controlled. Files are never sent via open links. Instead, transfers are made directly between named users, with every action logged for accountability and auditing.

GDPR-aligned features include:

• End-to-End Audit Trails: Track all user actions – uploads, downloads, views – to support documentation and investigations.
• Geo-Controlled Data Residency: Choose where encrypted data shards are stored, helping you meet location-specific obligations.
• Right of Access & Erasure Support: Quickly identify and manage files related to individual data subjects.
• Customisable Retention Rules: Apply expiry dates and download limits to enforce retention policies.

MX equips your organisation with the infrastructure needed to handle personal data responsibly – helping you meet GDPR obligations with greater control and confidence.

02. What specific GDPR requirements does MX address?

MX directly supports several core requirements of the General Data Protection Regulation (GDPR), particularly those related to data security, access control, transparency, and accountability. While GDPR compliance is a shared responsibility between the platform and the data controller (your business), MX provides the technical infrastructure necessary to fulfil many of your obligations.

Key GDPR provisions MX helps address include:

• Article 5 – Data Integrity & Confidentiality: MX enforces named-user access, encrypted storage, and secure transfers to maintain confidentiality and integrity.
• Article 15 – Right of Access: Audit trails and structured file logs allow you to trace user interactions and respond to data access requests.
• Article 32 – Security of Processing: MX uses quantum-safe encryption, anonymisation, and sharding to secure personal data at rest and in transit.
• Article 30 – Records of Processing Activities: MX provides detailed logging of all file exchanges, supporting internal documentation and compliance reporting.

MX also supports geo-specific data hosting, helping businesses maintain data within the EU or UK as required. For further detail, you can explore our approach to data residency and storage security.

MX gives your organisation the controls, transparency, and data protection measures needed to confidently meet GDPR requirements.

03. How does ISO compliance benefit my business with MX?

ISO compliance – particularly ISO/IEC 27001 and ISO/IEC 27018 – brings significant benefits to your business when using MX. These internationally recognised standards help establish trust, demonstrate accountability, and ensure best-practice handling of personal and sensitive information – especially when processing data under UK GDPR regulations.

MX’s architecture and security features align with ISO principles, giving you built-in support for data confidentiality, integrity, and availability. Whether you’re managing employee records, client files, or sensitive project documents, ISO compliance helps reduce legal risk and strengthens your position during audits, tenders, and client reviews.

Key business benefits include:

• Stronger Risk Management: ISO-aligned security controls minimise the likelihood of data breaches or access misuse.
• Improved Audit Readiness: With real-time activity logs and structured access control, MX simplifies ISO and GDPR audit preparation.
• Trust & Market Credibility: ISO compliance signals to clients, partners, and regulators that your business follows global best practices.
• Operational Consistency: ISO frameworks promote repeatable, secure workflows – key to scaling without security gaps.

According to the International Organization for Standardization (ISO), organisations that follow ISO/IEC 27001 are better equipped to respond to security threats and demonstrate privacy accountability.

With MX, ISO compliance becomes an operational asset – helping your business stay secure, credible, and ready for whatever regulatory or client demands come next.

04. Is data shared on MX encrypted to meet GDPR standards?

Yes – every file shared via MX is encrypted using advanced methods that align with the technical and organisational safeguards required under GDPR Article 32. MX’s encryption approach is not only compliant, but also exceeds many baseline standards by integrating quantum-safe encryption and patented ASR technology – Anonymise, Shard, Restore – to protect data in transit and at rest.

Unlike typical platforms that rely on link-based access or generic encryption, MX ensures that only named, verified users can decrypt and access files. This dramatically reduces exposure risk and strengthens GDPR-aligned data minimisation and access control policies.

GDPR-compliant encryption and sharing features include:

• End-to-End Encryption: Files are encrypted before transmission and remain encrypted on MX’s servers until retrieved by authorised users.
• Named-User Access Control: Eliminates link-based file sharing – only specific individuals can view or download shared data.
• Region-Specific Hosting: Choose UK or EU-based data zones to support cross-border data transfer compliance.
• Audit Logging: Full traceability of access, downloads, and changes – ideal for Article 30 recordkeeping obligations.

MX’s architecture supports key GDPR principles like data protection by design, access limitation, and accountability – backed by technology purpose-built for regulatory-grade security.

By encrypting every file and enforcing strict access controls, MX helps businesses meet GDPR obligations with confidence – keeping shared data secure, traceable, and fully compliant.

05. Can MX support my business in meeting GDPR audit needs?

Absolutely – MX is specifically engineered to support businesses in preparing for and passing GDPR audits. With built-in features like comprehensive audit trails, data access controls, encryption, and data residency options, MX provides the visibility and documentation needed to demonstrate compliance with GDPR’s strict accountability and transparency principles.

Every file interaction – whether it’s an upload, download, or permission change – is time-stamped and associated with a specific user. These logs can be exported for auditors, making it easier to show how your organisation manages data lawfully, transparently, and securely.

GDPR audit support features include:

• Full File Activity Logs: Every access or change is recorded for easy traceability and export during audits.
• User-Level Permissions: Demonstrate data minimisation by showing access is granted only when necessary.
• Region-Specific Data Hosting: Ensure personal data remains within the UK or EU as required – see our UK Data Protection Act page for more.
• Encryption & Revocation: Show encryption in transit and at rest, with the ability to revoke access if data sharing exceeds its purpose.

MX aligns with audit expectations outlined by the European Data Protection Board (EDPB), making GDPR readiness part of your everyday file workflows.

With MX, your business gains the tools and transparency needed to satisfy GDPR audits – without disrupting daily operations.
