Your data flows in a single architecture compliant with both regimes at once.
The lawful architecture of intra-group and supplier data flows, using KVKK's current transfer regime (standard contract, binding corporate rules, undertaking) and GDPR safeguards.
What did the new regime change?
After the 2024 amendments, KVKK's transfer regime settled onto three tiers: an adequacy decision; appropriate safeguards (binding corporate rules, a standard contract announced by the Board, a written undertaking); and limited incidental circumstances. In practice, the busiest route is the standard contract — and the most critical detail is the obligation to notify the Board within five business days of signing. A contract without notification is, in itself, grounds for a sanction.

Typical flows and the right mechanisms
Türkiye → Germany headquarters
the flow of HR, CRM and finance data to group systems; standard contract + intra-group arrangement on the GDPR side.
EU → Türkiye
processing the German subsidiary's data in Türkiye; the GDPR standard contractual clauses (SCC) + a transfer impact assessment.
Cloud and SaaS
every tool whose server is abroad is a transfer — there is no compliance without an inventory.
E-commerce
keeping EU customer data in systems located in Türkiye; the two-way setup we detail in our e-commerce guide.
The architectural approach
Transfer compliance is not a document-collection exercise but an architectural one: a data-flow map is drawn up, the right mechanism is assigned to each flow, the contracts are signed as a single set, and notification/recording obligations are put on a schedule. In group structures, the goal is that every new subsidiary or tool can be added to the existing architecture — not a project from scratch each time.
What gets asked in an audit?
Transfer compliance is tested in two places: a Board review, and the investigation that follows a data breach. The evidence you will be asked for is predictable — a current inventory of flows, the reasoning behind the mechanism chosen for each one, signed contracts and notification records, and assessment notes on the risk in the receiving country. On the GDPR side, post-Schrems II practice requires that where the standard contractual clauses are not enough on their own, the supplementary measures — encryption, access architecture, transparency reports — are documented. Enforcement cuts two ways: alongside an administrative fine there is the risk that the transfer itself is suspended, and for the business that is the real cost. The EU end of the regime is summarised in our GDPR record.

Who is it for, and what do you get?
The service is used most often by groups whose central systems sit in Germany, by cloud- and SaaS-heavy operations, and by the software, call-centre and e-commerce companies serving EU customers.
What you get is a single audit-ready file: the inventory, the reasoning for each mechanism, the contracts and the notification receipts, together with a transfer impact assessment template and an annual review calendar. The programme layer as a whole is carried forward in our data focus area.

The notification obligation lies with the data controller (and, depending on the scenario, the processor as well). Missing the five-business-day deadline can lead to an administrative fine; we manage the signature and notification timeline as a single process.
No — the two regimes use separate instruments. The EU side is secured with the SCCs, the Türkiye side with the KVKK standard contract; we set the two up as a single, non-conflicting package.
Explicit consent survives in a limited form among the incidental cases; for continuous flows, however, an appropriate safeguard (such as the standard contract) is essential. Legacy consent-based arrangements should be…
The essence of the text must be preserved; deviating from the content announced by the Board makes the validity of the safeguard questionable. Commercial annexes are handled in a separate agreement.
