Differences most comparisons miss
Worth knowing about OneTrust
- G2 has only 5 reviews for the TPM product; Gartner Peer Insights shows 4.1 from 177 ratings and GetApp 4.3 from 57, so the G2 score is thin evidence.
- Continuous monitoring relies on third-party security-rating integrations rather than a native scoring engine (per integration pages).
- Adds ethics and compliance screening (PEP, sanctions, adverse media) beyond security questionnaires.
- Sold as a module of a wider privacy and GRC platform, so cost depends on bundle.
Worth knowing about Vanta
- AI security reviews, continuous monitoring, vendor inventory and the TPRM API are add-ons, not in base plans.
- Questionnaire automation is capped at 25 per year on Plus and 144 on Professional.
- The Vendors page itself is included on all plans per the help center.
- Vendr median contract about $20,000/yr for Vanta overall (not the VRM add-on alone)
