What is the difference between Third-Party Risk Management (TPRM) and C-SCRM?

TPRM and C-SCRM share overlapping scope but serve distinct purposes, and organizations often treat them as interchangeable when they are not.

Third-Party Risk Management (TPRM): TPRM is the enterprise-level discipline covering risks introduced by any third party - vendors, suppliers, partners, service providers, and others. TPRM assessments typically include financial viability, operational resilience, compliance posture, legal and contractual risk, reputational risk, and cybersecurity posture. TPRM programs are usually owned by enterprise risk management or procurement functions and touch every business relationship.

Cyber Supply Chain Risk Management (C-SCRM): C-SCRM is focused specifically on cybersecurity risks that enter an organization through its supply chain - particularly through technology components, software, hardware, and services that become part of the organization's products or infrastructure. C-SCRM goes beyond vendor cybersecurity posture assessments to address: the integrity of software components (was the code tampered with or injected with malicious components?); hardware provenance and counterfeiting risks; Software Bill of Materials (SBOM) transparency; the security of the software development lifecycle at suppliers; and multi-tier supply chain risks (your supplier's supplier). C-SCRM is typically owned by IT security or product security teams and requires technical controls like code signing verification and SBOM dependency analysis.

For most organizations: TPRM handles the broader portfolio of vendor relationships. C-SCRM handles the technical depth required for software and hardware supply chains. Both programs should share data and coordinate on high-risk technology vendors.
