In legal practice, MFT means Managed File Transfer: the secure, controlled and auditable transfer of electronic files between organisations, users or systems. It is not defined in legislation or case law but is a widely used technical term in commercial, outsourcing and data protection contexts.
Legal significance: parties adopt MFT to evidence appropriate technical and organisational measures, reduce personal data breach risk, and meet information security obligations. Typical contract drafting (e.g., in IT procurement, data processing agreements and data sharing agreements) specifies encryption in transit and at rest, authentication, integrity checks, logging/audit trails, access controls, retention/deletion, key management, resilience, incident response, service levels, audit rights, and certifications (e.g., ISO/IEC 27001, SOC 2). Clauses often address data location, cross-border transfers and subprocessors.
Regulatory context: in the UK, MFT is commonly referenced to support compliance with the UK GDPR and Data Protection Act 2018, the Network and Information Systems Regulations 2018 and sectoral rules (e.g., FCA/PRA expectations, NHS DSPT). In Ireland, the same concept supports compliance with the EU GDPR and Irish Data Protection Act 2018 and evolving NIS2 implementation. Usage and expectations are broadly consistent across England & Wales, Scotland, Northern Ireland and Ireland, with terminology reflecting the relevant UK/EU regime.
