Third-Party Risk Management (TPRM) has become a critical extension of Governance, Risk, and Compliance (GRC) programs as organizations increasingly rely on vendors, suppliers, and subcontractors for essential operations. With 60% of organizations working with over 1,000 third parties — and many relying on fourth parties (the vendors of vendors) — modern GRC frameworks must address cascading risks across this interconnected ecosystem. Below, we examine the risks and strategies for integrating TPRM into broader GRC efforts.
Key Risks in Third- and Fourth-Party Relationships
Operational Disruptions
Fourth-party failures can disrupt critical services, as seen when a subcontractor’s cybersecurity breach forces a key vendor to suspend operations. For example, a manufacturing company might face production delays if a fourth-party raw material supplier fails compliance audits. These disruptions can severely impact business continuity and service delivery, making operational resilience a major concern when complex supply chains are involved.
Compliance and Regulatory Exposure
A growing number of regulations now hold organizations accountable for fourth-party breaches. For example, a healthcare provider could face HIPAA penalties if a fourth-party data processor experiences a breach. This regulatory exposure has expanded significantly in recent years, as legislators worldwide have recognized the interconnected nature of modern business operations and are demanding greater oversight across the entire vendor ecosystem.
Financial and Reputational Damage
Reputational harm often follows a breach as customers lose trust in organizations that fail to protect their data. These damages extend beyond immediate financial impacts, affecting customer acquisition, retention, and overall brand value in ways that can take years to recover from.
Shadow IT Risks
30–40% of IT budgets fund unapproved tools and services, creating unmonitored attack vectors. Shadow IT presents a particularly challenging risk vector because these unauthorized systems often bypass standard security controls and vendor management processes, creating blind spots in an organization’s risk posture that may only become apparent after a breach has occurred.

Strategies for Visibility and GRC Integration
Map and Classify Vendor Relationships
Creating an inventory of third and fourth parties is essential, with priority given to those handling sensitive data or critical infrastructure. Organizations should implement systematic approaches to documenting these relationships, including data flow maps and dependency charts.
Implement Continuous Monitoring
Continuous monitoring represents a significant advancement over traditional annual assessments, providing timely risk indicators that can trigger mitigation actions long before a breach occurs.
Strengthen Contractual Controls
Organizations should mandate fourth-party visibility clauses in third-party contracts, including audit rights and breach notification timelines. These contractual provisions establish clear expectations for transparency and create legal mechanisms for enforcing security standards. Aligning service-level agreements (SLAs) with frameworks like NIST CSF and ISO 27001 ensures that vendors adhere to recognized security practices and provides a common language for assessing controls.
Leverage AI and Automation
Automating vendor onboarding with predefined risk criteria can streamline the process while maintaining consistent standards. This automation reduces manual effort while ensuring that no critical assessment steps are missed. Organizations are increasingly using AI-powered platforms to analyze questionnaire responses and flag compliance gaps, enabling faster and more accurate vendor assessments. These technologies can identify patterns and inconsistencies that might be missed in manual reviews, providing deeper insights into potential risks while reducing the resource burden on security and compliance teams.
Embed Third-Party Risk Management (TPRM) into GRC Processes
- Risk Assessment: Conducting joint assessments that evaluate third-party financial stability, incident response plans, and subcontracted services provides a holistic view of vendor risk. These assessments should consider not just cybersecurity factors but also broader operational, financial, and compliance considerations. By integrating TPRM with enterprise risk frameworks, organizations can ensure consistent risk evaluation across all business relationships.
- Governance: Establishing a cross-functional GRC committee to oversee vendor risk thresholds and mitigation strategies ensures appropriate executive visibility and resource allocation. This committee should include representatives from security, legal, procurement, and business units to provide diverse perspectives on risk management priorities. By embedding TPRM governance within broader GRC structures, organizations can ensure alignment with enterprise risk appetites and avoid siloed decision-making.
- Compliance: Mapping vendor practices to regulations helps organizations stay ahead of regulatory requirements. GRC tools with prebuilt questionnaire libraries can streamline this process, ensuring that compliance assessments address all relevant regulatory domains. By maintaining a current regulatory inventory and mapping vendor controls to these requirements, organizations can efficiently demonstrate compliance while identifying potential gaps requiring remediation.
By treating TPRM as a core GRC function — rather than a compliance checkbox — organizations can build resilient partnerships while meeting evolving regulatory demands. As we’ve learned from Gartner’s 2025 guidance, the most effective GRC programs now view vendor ecosystems as extensions of their own risk posture.
