What Makes a File Sharing Solution ‘Compliant’ in 2025?

Compliance in file sharing is not a single tick-box. It is a blend of legal obligations, auditable controls, and security behaviours that help an organisation prove it treated data properly. In 2025, regulators expect evidence, not promises. A file sharing solution is “compliant” when it can help you demonstrate conformance with applicable laws and standards through controls, records, and predictable outcomes.

My MX Data focuses on controlled exchanges between named users, with strong encryption, rigorous audit trails, and a quantum secure patented methodology that anonymises, shards, and restores data. These capabilities facilitate GDPR and ISO 27001 alignment by delivering traceability and security options. They do not guarantee compliance. Your policies and processes still matter.

What makes a file sharing solution “compliant” in 2025

In short, the platform should help you enforce policy, reduce risk, and prove what happened. The essentials are consistent across frameworks.

• Lawful basis and data minimisation: Only the right people see the right data for the stated purpose. Include role based controls and least privilege. Data minimisation Collect and share only what is necessary for the specified purpose, then keep it no longer than needed.

• Strong encryption and key handling: Use 256 bit AES in transit and at rest, plus options that anticipate quantum threats. My MX Data’s ASR approach is a quantum aware methodology that supports long term confidentiality.
• Named user access: No public links, no uncontrolled resharing. Access is explicit and time bound.
• End to end audit trails: Track who sent what, when, from where, and what happened next. Auditability A complete, immutable record of actions to support incident investigation and regulatory reporting.

• Retention and deletion controls: Expiries, revocation, and defensible deletion policies, with logs to prove enforcement.
• Data sovereignty choices: Ability to select storage regions and document cross border conditions. International transfers Transfers outside the UK or EEA often require safeguards like SCCs and transfer risk assessments.
  B2B secure exchange
• Incident response support: Forensics ready logs and rapid access revocation to help contain issues and notify correctly.

Why this matters: regulators and risk do not wait

GDPR fines since 2018 exceed EUR5.88 billion, with EUR1.2 billion issued in 2024 alone. Ireland remains the most active enforcer by value. These figures are not abstract. They signal expectations around proof, policy, and control. The secure file transfer market is growing fast, estimated around $2.5 billion in 2025, reflecting demand for solutions that help organisations act responsibly and show their work.

Features that map to obligations

Here is a compact view of how common regulatory expectations can be supported by platform capabilities.

Different standards, similar themes

GDPR, ISO 27001, and sector rules orbit the same principles: control, security, and evidence. The differences sit in phrasing, scope, and reporting.

Where My MX Data fits in your control stack

My MX Data is designed for secure file sharing for business where traceability, policy enforcement, and data residency are important. It provides end to end audit trails, named user controls, and a quantum aware ASR methodology. Quantum resistant adoption in the wild remains very low, for example around 0.029 percent for OpenSSH, so preparing now adds resilience for long term confidentiality.

Enterprise teams can review enterprise file sharing and B2B secure exchange.

Quick market context: the secure file transfer segment is projected to grow from about $2.5 billion in 2025 to more than $3.2 billion by 2028. Most enterprises share with hundreds of domains and use multiple services, which increases the need for governance, auditability, and consistent controls.
