OneTrust Third-Party Risk Exchange vs Tenchi Zanshin: Side-by-Side Comparison (2026)

OneTrust Third-Party Risk Exchange

Mid-market and enterprise security teams drowning in vendor questionnaires will find real relief in OneTrust Third-Party Risk Exchange; it populates your inventory automatically and rescores risk continuously instead of waiting for annual assessments. The platform ingests data from SecurityScorecard, RiskRecon, and SupplyWisdom simultaneously, giving you triangulated risk signals rather than single-source blind spots. Skip this if your third-party program is still manual or you're looking for a lightweight screening tool; OneTrust assumes you have dozens or hundreds of vendors and the operational capacity to act on workflow triggers at scale.

Tenchi Zanshin

Mid-market and enterprise security teams managing vendor risk across distributed third-party ecosystems should choose Tenchi Zanshin for its non-intrusive continuous monitoring that doesn't require vendor API keys or agent deployment. The platform covers NIST GV.SC supply chain risk management and DE.CM continuous monitoring, with daily automated testing that surfaces real-time remediation timelines rather than static risk scores. Skip this if your vendor base is small enough for manual quarterly assessments or if you need deep integration with your existing GRC platform; Tenchi's strength is scale and autonomous discovery, not replacing your compliance workflow.
