3rdRisk Platform vs Tenchi Zanshin: Side-by-Side Comparison (2026)

3rdRisk Platform

Mid-market and enterprise buyers managing vendors across multiple regulatory domains will get the most from 3rdRisk Platform because it handles security, privacy, compliance, and sustainability risks in one workspace instead of forcing separate tools per domain. The platform maps directly to NIST GV.SC and DE.CM, with continuous monitoring and real-time alerts that catch vendor incidents before they become your incident; DORA and NIS-2 compliance templates are built in rather than bolted on. Skip this if your vendor ecosystem is under 50 third parties or you need deep integrations with your existing GRC platform; 3rdRisk is strongest when you're consolidating multiple point solutions rather than supplementing an incumbent.

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.
