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.
