Introduction
In today's interconnected digital landscape, organizations increasingly rely on third-party vendors to enhance efficiency, reduce costs, and access specialized expertise. However, this reliance extends beyond direct partnerships, introducing a complex web of subcontractors and service providers—collectively known as fourth parties. These entities, though not directly contracted, can significantly impact an organization's operations, security, and compliance posture.
The significance of fourth-party risk has been underscored by incidents where vulnerabilities in a vendor's supply chain have led to substantial breaches and operational disruptions. For instance, the 2020 SolarWinds attack exploited vulnerabilities in a third-party vendor's software, affecting numerous organizations downstream. Such events highlight the cascading nature of supply chain risks and the imperative for organizations to extend their risk management practices beyond immediate vendors.
Despite the evident risks, many organizations lack visibility into their extended supply chains. Traditional risk management frameworks often focus solely on direct vendors, neglecting the intricate networks that support them. This oversight can lead to compliance violations, data breaches, and reputational damage.
To effectively manage these risks, organizations must adopt comprehensive strategies that encompass not only their immediate vendors but also the extended network of fourth-party relationships. This involves implementing robust risk assessment protocols, enhancing supply chain transparency, and fostering collaboration across all tiers of the supply chain.
By proactively addressing fourth-party risks, organizations can strengthen their overall risk posture, ensure regulatory compliance, and safeguard their operations against unforeseen disruptions.
What Are Fourth-Party Risks?
In today's complex business ecosystems, organizations often rely on third-party vendors to provide essential services. However, these vendors, in turn, may depend on their own subcontractors or service providers, known as fourth parties. Fourth-party risk refers to the potential threats and vulnerabilities associated with these indirect relationships.
Unlike third-party vendors, with whom organizations have direct contracts and oversight, fourth parties operate outside the immediate purview of the contracting organization. This lack of direct interaction makes it challenging to assess and manage the risks they pose. Bitsight highlights that these risks can include cybersecurity threats, compliance issues, and operational disruptions.
For example, consider a scenario where a company outsources its payroll processing to a third-party vendor. This vendor, in turn, uses a cloud-based service for data storage. If the cloud service (the fourth party) experiences a data breach, the company's employee data could be compromised, even though the company has no direct relationship with the cloud provider.
Managing fourth-party risks requires organizations to extend their risk management frameworks beyond direct vendors. Ncontracts emphasizes the importance of understanding the entire supply chain and implementing strategies to monitor and mitigate risks at all levels.
Furthermore, Prevalent suggests that organizations should require third-party vendors to disclose their critical subcontractors and ensure that these fourth parties adhere to appropriate security and compliance standards.
The Expanding Risk Perimeter in 2025
In 2025, the digital transformation of supply chains has significantly expanded the risk perimeter for organizations. The integration of advanced technologies, while enhancing efficiency and visibility, has also introduced new vulnerabilities that cybercriminals are eager to exploit. As supply chains become more interconnected and reliant on digital tools, the potential attack surface for malicious actors grows exponentially.
According to Xeneta, one of the top risks facing supply chains in 2025 is the increased exposure to cyber threats due to the rapid digitization of logistics and procurement processes. The reliance on cloud-based platforms, IoT devices, and AI-driven analytics has created multiple entry points for cyberattacks, making it imperative for organizations to reassess their cybersecurity strategies.
Achilles highlights that while digital transformation offers numerous benefits, it also brings about a growing set of cyber threats that can severely disrupt operations. The complexity of multi-tiered global supply chains means that a single vulnerability in one part of the network can have cascading effects throughout the entire system.
The rise in supply chain attacks is evident, with AgileBlue reporting a significant surge in such incidents. These attacks often target third-party vendors or software providers, exploiting their systems to gain unauthorized access to larger networks. This trend underscores the importance of not only securing one's own infrastructure but also ensuring that partners and suppliers adhere to robust cybersecurity standards.
Furthermore, Cyber Defense Magazine emphasizes that the evolving threat landscape requires businesses to adopt proactive measures. This includes continuous monitoring, regular security assessments, and fostering a culture of cybersecurity awareness among employees.
In the industrial sector, Industrial Cyber notes that the convergence of IT and operational technology (OT) systems has further complicated the risk landscape. As factories and production lines become more connected, the potential for cyber incidents that can halt operations or compromise safety increases.
In conclusion, the expansion of the risk perimeter in 2025 is a direct consequence of the digital evolution of supply chains. Organizations must recognize that cybersecurity is no longer confined to their immediate operations but extends to every digital touchpoint within their network. By adopting a comprehensive and proactive approach to risk management, businesses can navigate the challenges of this new era and safeguard their operations against emerging threats.
Why Most VRM Programs Stop at the First Tier
Vendor Risk Management (VRM) programs are essential for organizations to assess and mitigate risks associated with third-party vendors. However, many VRM programs primarily focus on first-tier vendors, neglecting the extended network of subcontractors and service providers—known as fourth parties. This limited scope can leave organizations vulnerable to hidden risks within their supply chains.
One reason for this narrow focus is the complexity involved in managing extended supply chains. As highlighted by the Wiley Online Library, managing extended supply chains that lie beyond first-tier suppliers presents significant challenges, including limited visibility and control over subcontractors.
Additionally, the lack of standardized processes for assessing and monitoring fourth-party risks contributes to the issue. Many organizations lack the tools and frameworks necessary to effectively evaluate the security posture and compliance of their vendors' vendors. This gap in oversight can result in unaddressed vulnerabilities that may be exploited by malicious actors.
The reliance on manual processes and outdated technologies further hampers the ability to manage risks beyond the first tier. Traditional VRM programs often involve labor-intensive assessments and audits, making it difficult to scale risk management efforts to encompass the entire supply chain. As noted by Mitratech, building an effective VRM program requires careful planning and execution, which can be resource-intensive.
Moreover, organizational silos and lack of cross-functional collaboration can impede the extension of VRM programs beyond the first tier. Without clear communication and coordination between departments such as procurement, compliance, and IT, it becomes challenging to implement comprehensive risk management strategies that address the full spectrum of vendor relationships.
To overcome these challenges, organizations should consider adopting a tiered approach to vendor risk management. As explained by UpGuard, vendor tiering involves classifying vendors based on the level of risk they pose, allowing for more focused and efficient risk management efforts. By extending this approach to include fourth-party vendors, organizations can better identify and mitigate potential risks within their extended supply chains.
In conclusion, while VRM programs are crucial for managing third-party risks, their effectiveness is limited when they stop at the first tier. To enhance resilience and protect against emerging threats, organizations must expand their risk management efforts to encompass the entire supply chain, including fourth-party vendors.
Mapping and Monitoring Fourth-Party Relationships
In today's interconnected digital landscape, organizations often rely on third-party vendors to provide essential services.

Conclusion: The Need for Tiered Visibility in Risk Governance
The risk landscape in 2025 has evolved well beyond traditional third-party oversight. As organizations deepen their reliance on extended digital supply chains, the need for visibility into fourth-party relationships has become not just a best practice, but a governance imperative.
Most traditional vendor risk management programs focus narrowly on first-tier suppliers. However, breaches and disruptions increasingly originate from fourth parties—vendors of your vendors—who often lack direct contractual ties but hold indirect influence over your operations and data. This lack of visibility creates blind spots that threat actors are quick to exploit.
To overcome this, organizations must adopt a tiered approach to risk governance that includes all entities in the vendor ecosystem. Real-time intelligence, like that discussed in Continuous Vendor Risk Monitoring: A Guide to Real-Time Oversight, is essential. These capabilities allow organizations to detect shifts in vendor posture or new vulnerabilities introduced downstream, without waiting for the next periodic audit cycle.
Moreover, fourth-party visibility must not remain isolated from broader enterprise efforts. As outlined in Integrating Internal and Vendor Risk: A Unified Approach, governance frameworks must treat internal and external threats with equal rigor, mapping them across shared dependencies and critical processes.
In essence, tiered visibility is not merely about monitoring more vendors. It’s about understanding the systemic interdependencies that define today’s operational ecosystem. Risk managers, CISOs, and board-level committees must view this extended visibility as foundational to resilience, not optional enhancement.
Organizations that operationalize this mindset will not only safeguard their brand and operations but also build enduring trust across the value chain. Those that don’t may find themselves blindsided by risks they never realized existed—until it’s too late.
