Framework & methodology
How a real TPRM program is built
Risk tiering, framework selection, and assessment scoring - the structural layer most vendor directories skip.
Third-Party Risk Management
The methodology layer of vendor risk: how a real TPRM program is built, what it should catch, and how to tell a genuine practice from a checkbox exercise.
Third-Party Risk Management Framework
NIST, ISO, and the Shared Assessments maturity model compared - pick the framework that matches your regulator and your program's actual maturity, not the one with the most name recognition.
Third-Party Risk Assessment
Inherent risk, residual risk, and how a real assessment gets scored - what separates a genuine methodology from a questionnaire that goes in a drawer.
Due-Diligence Framework
Scope, evidence standards, decision thresholds, sign-off authority - the components a due-diligence framework needs to produce a consistent, defensible decision every time.

Frequently asked questions
What is Procurement Proof?
A procurement-grade reference for third-party risk management (TPRM) and procurement due-diligence - the methodology and advisory layer, not point-verification tools or GRC software platforms. It explains how a real TPRM program is built, what to verify before you retain an advisory firm, and pairs each guide with a sourced reference to notable real firms in the space.
Is this a compliance guarantee or legal advice?
No. Procurement Proof is procurement support and buyer education only. It does not provide a compliance guarantee, does not audit your vendors, and does not provide legal advice. Standards-body citations are informational context, never a claim that this index or a listed vendor satisfies a regulator.
How do I source a TPRM advisor here?
Use the sourcing request form to submit a procurement-safe scope and the service category you need. We route it toward qualified third-party risk management advisory firms and procurement due-diligence consultancies. Keep confidential vendor risk reports or internal system details out of the request.
Does it cost anything?
The guides, glossary, and vendor reference are free to use. Featured and Verified placements are clearly labeled and never change the editorial content or ordering.
