Partly fits

Bold Matrix Vendor Risk Enginepartial · 55

It focuses on pre-signature screening rather than ongoing monitoring across vendors over time.

Won’t cover: Helps you screen vendors before you sign, but it’s not positioned as a continuous monitoring system for ongoing vendor risk changes.

Riskifypartial · 52

It emphasizes continuous monitoring of non-financial risks, but it isn’t clearly framed as third-party/vendor risk monitoring specifically.

Won’t cover: It targets broader non-financial risk monitoring, rather than explicitly tracking risks from your specific third-party vendors over time.

DORApppartial · 48

It centralizes ICT third-party vendor risk tracking and creates audit-ready reporting, but it’s specifically oriented to DORA compliance for financial institutions.

Won’t cover: It’s focused on DORA compliance and financial-institution reporting, which may be narrower than general vendor risk monitoring needs.

OWASP Dependency-Trackpartial · 45

It provides continuous tracking of supply-chain risk in software components, which can relate to vendor risk, but it’s about software dependency risk rather than third-party/vendor relationships.

Won’t cover: It focuses on SBOM-based supply-chain risk in software components, not ongoing risk monitoring of vendors and partners as third parties.
