OneTrust vs Turkey-Based CMPs: A Decision Guide for KVKK Compliance (2026)

TL;DR: OneTrust is the enterprise heavyweight of privacy tech — but for companies whose primary regulatory exposure is Turkey’s KVKK, weight is not the same as fit. This guide compares OneTrust with Turkey-based CMPs across compliance fit, implementation effort, data residency and total cost, and explains when each choice makes sense.

Where OneTrust excels

OneTrust offers the broadest privacy suite on the market: consent management, DSAR automation, vendor risk, assessments and more. For multinationals juggling GDPR, CCPA, LGPD and a dozen other regimes from one dashboard, that breadth is the point. It supports IAB TCF 2.2, Google Consent Mode v2 and virtually every enterprise integration.

The decision framework

Choose OneTrust when: you operate across many jurisdictions, need DSAR/assessment modules beyond cookie consent, and have a privacy team to run it.

Choose a Turkey-based CMP when: KVKK is your primary exposure, you need audit-ready consent records the Turkish DPA will accept without argument, your legal team works in Turkish, or procurement requires TRY invoicing and local data residency.

Hybrid reality: several Turkish enterprises run OneTrust group-wide but deploy a local CMP for their .com.tr properties — the two coexist, with the local CMP handling KVKK-specific banner logic and consent records. Cerezgo supports geo-based rule sets for exactly this scenario, alongside IAB TCF 2.2 and Consent Mode v2.

Migration checklist (OneTrust → local CMP)

  1. Export and archive existing consent records for audit continuity.
  2. Inventory your tags; re-scan with the new CMP’s crawler.
  3. Replace the CMP script; map categories to Consent Mode v2 signals.
  4. Rebuild the Turkish notice layer per the KVKK Guideline (equal-weight accept/reject).
  5. Validate with Tag Assistant and run both banners in staging before cutover.

FAQ

Is OneTrust non-compliant with KVKK?

No — it can be configured compliantly. The difference is effort and defaults: guideline-native banners, Turkish notices and locally hosted consent records come standard with local platforms.

What does the Turkish DPA actually check?

Whether non-essential cookies fire before consent, whether reject is as easy as accept, whether a Turkish notice exists, and whether you can produce consent records on request. Fines in 2026 range from TRY 85,437 to TRY 17,092,242.

Can Cerezgo handle non-Turkish traffic?

Yes — geo-based rules serve a TCF 2.2 banner to EEA visitors and a KVKK banner to Turkish visitors from one installation.

How long does migration take?

For a typical corporate site, under a week including legal review; the script swap itself is same-day.
