Navigating International Data Transfers in 2025
Estimated read time: 5 minutes
Cross-border data flows underpin everything from payroll and cloud to personalisation. In 2025, they’re also a competitive edge: teams that make transfers clear, proportionate, and evidenced move faster and face fewer partner/security blockers.
The 2025 decision path (quick view)
Q1. Destination & recipient — if US and the recipient is certified to the UK extension of the Data Privacy Framework, you can use the UK–US data bridge (for UK-origin data). Otherwise, use SCCs + UK Addendum (or the UK IDTA) and perform a proportionate transfer risk assessment (TRA).
Q2. Purpose & necessity — record why the transfer is necessary for the stated purpose (minimisation by design).
Q3. TRA essentials — assess destination laws/technical context, your controls, and residual risk; align to ICO TRA guidance/tool.
Q4. Onward transfers — make sure sub-processors and support routes are covered by your chosen mechanism and contract.
Your 2025 toolkit (what to actually use)
1) UK–US ‘Data Bridge’ — when the US recipient is certified to the UK extension; log scope and expiry from the public register.
2) SCCs + UK Addendum / UK IDTA — workhorse tools for most SMEs with mixed EU/UK stacks; link them to your TRA.
3) DPF/UK resources — keep evidence (certificate, scope, renewal date) and file it in your audit pack.
What “good” looks like (make this your standard)
Proportionality by default — prefer assertions over full document copies where feasible.
Clarity + explainability — one page that covers what/why/where/how long/who sees it/how to challenge.
Evidence you can produce in a week — mechanism, TRA summary, certificate (if applicable), retention decisions, sub-processor list.
Onward-transfer discipline — short onward-transfer map and verification of sub-processors’ mechanisms.
Security posture — encryption, key management ownership, role-based access, incident first-hour plan.
Vendor assurance pack (lightweight but defensible)
Mechanism evidence — DPF/UK certificate or executed SCCs + Addendum / IDTA (with modules).
TRA notes — risks considered and mitigations (you still perform your own TRA).
Retention & deletion — time-bound storage and verified deletion routes.
Onward transfers — current sub-processor register and locations.
Incident posture — detection/response summary and recent post-incident reviews (sanitised).
30 / 60 / 90-day plan (to ship, not shelve)
Day 0–30 — inventory all transfers; tag each by mechanism; pull certificates and file them.
Day 31–60 — refresh TRAs for top 5 transfers; standardise contract exhibits.
Day 61–90 — ship a minimisation change; publish a short 'What we changed and why'; set recertification review reminders.
Common pitfalls (and quick fixes)
Assuming every US vendor is covered by the bridge — verify certification and scope.
Copy-pasting SCCs without correct modules — add the UK Addendum where needed and map modules to the relationship.
Letting TRAs go stale — revisit after material changes.
