Why this comparison matters
Didomi and OneTrust compete in the mid-market and enterprise consent space, but the comparison is as much about regulatory philosophy as product features. Didomi was founded in Paris in 2017 with GDPR as its primary design constraint — the product is built around consent UX, preference centres, and compliance notices, with EU data hosting as a default. OneTrust is the market-share leader globally and was built to cover the broadest possible privacy regulation surface across all jurisdictions. The key structural difference is sovereignty: Didomi is a French company under EU law, with EU data processing as its operating norm. OneTrust is headquartered in Atlanta and subject to US CLOUD Act jurisdiction — meaning US federal law enforcement can compel disclosure of data held by OneTrust or its cloud providers, regardless of where that data is stored. For EU organisations processing sensitive personal data categories under GDPR Article 9, this distinction is material and should appear in your Article 28 DPA review. On features, OneTrust is genuinely broader — its modules cover data subject requests, vendor risk assessments, DPIAs, ethics reports, and a growing governance product. Didomi's strength is consent UX quality and preference management depth, areas where it often outperforms OneTrust's consent module in A/B tests. If your primary need is consent and your primary concern is EU sovereignty, Didomi is the cleaner choice. If you need a single platform spanning consent plus a full privacy programme, OneTrust's breadth may justify the sovereignty trade-off for your risk profile.

Verdict by use case
EU financial services firm under DORA and GDPR, sovereign-first procurement policy
Didomi. EU-headquartered, consent-specialist, no CLOUD Act exposure. DORA procurement requirements around third-country sub-processing make US vendor risk harder to justify.
Global enterprise needing DSR automation + vendor risk + consent in one platform
OneTrust. The module breadth is unmatched. Mitigate CLOUD Act exposure via contractual protections and EU data residency configuration.
Mid-market EU SaaS prioritising consent UX conversion rates
Didomi. Its consent UX and preference centre tooling typically outperforms OneTrust's default consent module. Better for companies where consent rate optimisation is a business metric.
