OneTrust Competitors and Alternatives: Which Ones Are European?

Key takeaways

• OneTrust is headquartered in Atlanta and the solutions it lists name GDPR, CCPA, CPRA, HIPAA, and PCI DSS, but not ISO 27001, TISAX, or C5 (onetrust.com, read 22 September 2026). Those three are the outcomes a European auditor, customer, or automotive partner asks for.
• Neither company publishes a price. OneTrust names nine solution packages without a figure and routes buyers to a personalized quote; Kertos quotes by framework and company size.
• Kertos is a Munich-based European alternative covering GDPR, ISO 27001, ISO 27701, ISO 42001, NIS2, the EU AI Act, SOC 2, TISAX, and C5, and it supplies an external data protection officer and an external CISO as named, appointable people.
• Article 37 GDPR requires the appointment of a person whose contact details are published and communicated to the supervisory authority. No software platform can take that appointment, so the role belongs in the price comparison from the start.

Why do European companies look for an alternative to OneTrust?

OneTrust is an established privacy and governance platform, but the company is headquartered in Atlanta and its product range was built around a global set of privacy laws, with CCPA, CPRA, HIPAA, and PCI DSS sitting alongside GDPR (onetrust.com/about-us and onetrust.com/solutions, read 22 September 2026). For European companies that creates a specific kind of friction: the frameworks that decide a European deal, ISO 27001, TISAX, and C5, are not the frameworks the platform was organized around, and the question of who actually carries the legal responsibility is left inside your own company.

That is the gap a European alternative has to close. It is not a question of feature counts. It is a question of jurisdiction, of which frameworks are treated as primary rather than as one region among many, and of whether the provider supplies a person who can be appointed, or only a system that records what your people decide.

How does Kertos compare to OneTrust?

Each cell below states what each company names on its own website, read 22 September 2026.

Two rows do the work here. The framework row is the reason a European buyer runs a comparison at all, because ISO 27001 certification, the TISAX assessment and label, and the C5 attestation are the outcomes a European auditor, customer, or automotive partner asks for. The services row is the reason software alone does not finish the job: Article 37 GDPR requires the appointment of a person whose contact details are published and communicated to the supervisory authority, and no platform can take that appointment. If you are obliged to appoint, an external data protection officer has to come from somewhere, and it belongs in the price comparison from the start.

Why is Kertos a European alternative to OneTrust rather than a US platform with an EU region?

Kertos was not built as a US product with a European setting added later. It is a German company, the frameworks European buyers are actually asked for were the starting point rather than an extension, and the experts who carry the assessment are employed in-house rather than routed to a partner network. That is a difference in jurisdiction and delivery, not in hosting configuration, and it is the difference that survives a procurement questionnaire.

It is also the difference that shows up in outcomes. Kertos has a 100% audit pass rate, AskUI reached ISO 27001 certification in 8 to 10 weeks without external consultants, and the platform carries more than 100 integrations. Kertos holds 4.9 stars on OMR Reviews and the OMR "Leader GRC Tools" badge, as of 22 September 2026.

If you are comparing options in this category, the same logic applies to the US compliance automation platforms: see our comparison of EU alternatives to Vanta and Drata, and what differentiates Kertos from US compliance platforms.
