ISO 42001 coverage

Drata. ISO 42001 framework available with cross-mapping to ISO 27001 controls. Automated evidence collection covers approximately 60% of Annex A clauses.

OneTrust. ISO 42001 supported as part of the broader AI Governance module. Strong fit for enterprises with existing OneTrust deployments.

EU AI Act coverage

Drata. EU AI Act framework released in beta in early 2026. Coverage of obligations for providers is more complete than for deployers.

OneTrust. Dedicated EU AI Act module covering provider, deployer, and GPAI obligations. Most complete coverage on the market.

Pricing

Drata. Starting at ~€7,500/yr. Single framework, up to 100 employees.

OneTrust. Starting at Enterprise-only. Module licence, AI risk assessment workflow.

Implementation

Drata. Drata implementations typically run 10 to 14 weeks for a single framework. The platform requires more upfront configuration than Vanta but rewards that effort with cleaner ongoing operations.

OneTrust. OneTrust implementations typically run 6 to 12 months for first-time deployments. Organisations that already use OneTrust can extend in 8 to 16 weeks.

Verdict

Drata wins for mid-market teams that want strong ISO 42001 and ISO 27001 cross-mapping without enterprise GRC overhead. OneTrust wins for large enterprises with mature GRC functions running multiple AI regulations across regions, where its AI Governance module is the most complete in the category.

Our recommendation: Drata for the primary use case discussed above. The other tool remains a strong choice in the segments listed in its full review.
