02. How does MX ensure confidentiality for client financials?
MX protects client financial data by enforcing strict access controls, quantum-secure encryption, and full auditability – all designed to keep sensitive information confidential throughout the entire file lifecycle. Whether you’re sending tax returns, payroll records, or audit files, every transfer and storage event is governed by a zero-trust security model.
Files are never shared via public links. Instead, MX ensures they’re only accessible to named, authenticated users, with detailed logs showing exactly who accessed each file and when. This ensures accountants can maintain client trust while staying aligned with legal, GDPR, and accounting-specific confidentiality standards.
Confidentiality features tailored for accountants:
- Named-User Access Only: Files can’t be viewed, forwarded, or downloaded without explicit authorisation.
- AES-256 & Sharded Encryption: Client documents are anonymised and split into encrypted segments before storage or transfer.
- Client Upload Portals: Clients can submit sensitive financial documents securely via branded portals – no email attachments required.

As regulatory pressure increases on data security within financial services, MX gives accountants the infrastructure to operate with confidence and compliance.
MX helps accountants maintain absolute confidentiality – backed by encryption, traceability, and access controls purpose-built for sensitive client data.
03. Can MX support multiple government department file sharing?
Without question! MX is well-suited for secure file sharing across multiple government departments, agencies, and regulatory bodies. Whether you’re an accountant submitting documents to HMRC, working with local authorities, or coordinating with oversight agencies, MX ensures each interaction is encrypted, access-controlled, and fully auditable.
With features like named-user permissions, department-level access segmentation, and activity logs, MX helps firms manage multi-agency relationships while staying compliant with UK data protection laws, GDPR, and ISO 27001.
Capabilities designed for multi-department collaboration include:
- Per-Agency Access Control: Share specific files with designated users from each department – without exposing unrelated documents.

- Role-Based Restrictions: Limit access by department, case type, or compliance team.

04. Does MX provide file tracking features for accountants?
Absolutely – MX includes robust file tracking tools that are especially valuable for accountants handling sensitive financial records and regulatory submissions. Every file interaction is automatically logged and time-stamped, enabling you to monitor access, downloads, and activity across client documents in real time.
This level of visibility supports compliance with industry requirements, including GDPR, the UK Data Protection Act, and financial conduct rules. Whether you’re responding to an audit request or reviewing client activity, MX makes it easy to provide a verifiable digital trail.

For sure! MX enables accountants to share sensitive financial documents with clients securely and compliantly. Whether it’s tax returns, payroll reports, or audit files, every exchange is protected by quantum-safe encryption, named-user access, and full audit trails.
Public links and generic file-sharing services pose risks for client confidentiality. MX eliminates those vulnerabilities with private file handoffs, secure upload portals, and file expiry controls, ensuring that only the intended recipient can access sensitive data – on your terms.
Key features for secure accountant-client sharing include:
- Named-User File Access: Share documents with verified client contacts – no shared folders or anonymous access.
