Third-Party Risk by the Numbers: What Data Reveals About Supply Chain Vulnerabilities

Key Takeaways

The Modern Supply Chain: A Widening Attack Surface

The digital supply chain has undergone a profound transformation. What was once a small network of trusted vendors has evolved into a vast, interconnected web of technologies, platforms, and data flows.

Cloud providers now host mission-critical infrastructure. SaaS platforms handle sensitive data. Managed service providers, subcontractors, and open-source libraries form the unseen backbone of daily operations. Each of these relationships expands the attack surface, introducing new dependencies and new vulnerabilities.

A single vendor today may rely on dozens of others, each with its own third- and fourth-party relationships. The result is an ecosystem of thousands of potential ingress points, with many of them outside an organization’s direct line of sight. These dependencies are often invisible beyond the first tier, leaving businesses exposed to risks they may not even know exist.

Cybercriminals understand this. Supply chain compromises have become a preferred strategy for attackers because infiltrating a vendor is often easier and more scalable than targeting an organization directly. By compromising one trusted connection, adversaries can pivot to dozens of downstream victims, often before the original breach is even detected.

This expanding ecosystem demands a new approach. Securing the modern digital supply chain requires continuous, intelligence-led visibility, one that provides an external, real-time view of every partner and vendor’s security posture. Only with ongoing, data-driven insight can organizations uncover hidden exposures and detect emerging threats before small weaknesses become systemic failures.

The Unavoidable Truth: Key Third-Party Risk Statistics for 2025

Every year, the volume, cost, and complexity of vendor-related breaches continue to rise, exposing weaknesses that traditional risk management can’t contain. The following third-party risk statistics illustrate just how pervasive the problem has become and why a new approach is urgently needed.

Frequency and Volume

Third-party breaches are no longer isolated events. They are becoming a defining feature of the modern threat landscape.

According to Verizon’s most recent Data Breach Investigations Report, 30% of breaches involved a third-party vendor, twice as much as the previous year. However, this figure is likely conservative due to underreporting and misclassification, especially when the compromise occurs several layers deep in their vendor ecosystem.

Financial Impact

According to IBM’s 2024 Cost of a Data Breach report, the average cost of a third-party breach is over $5.08 million. Highly regulated sectors such as healthcare and finance face even steeper costs.

The true financial impact of a breach extends beyond the initial response, encompassing lost revenue, increased cyber insurance premiums, and reputational damage that drives customer churn. Organizations may also face expensive marketing and PR efforts to restore trust after a high-profile supply chain incident.

Dwell time — the duration between initial compromise and detection — compounds these costs. In 2024, organizations with a dwell time beyond 200 days faced average breach costs of $5.01 million.

Gartner research reveals that third-party breaches cost roughly 40% more to remediate than those that originate within an organization’s own systems, due to the additional complexity of managing incidents that span multiple entities, legal jurisdictions, and data environments. When breaches involve personally identifiable information (PII), PHI, or payment card data, costs can climb even higher as regulatory penalties and legal exposure multiply.

Hidden Dangers: Fourth-Party and Nth-Party Risk

Modern supply chains extend far beyond the vendors an organization directly manages. Each third-party relationship is underpinned by its own network of fourth and nth parties—subcontractors, technology providers, and cloud services. These indirect dependencies create exposure that most organizations can neither see nor control.

According to Whistic’s 2024 Third-Party Risk Management Impact Report, half of all companies work with more than 100 vendors, up from 38% in 2023. And for each third-party vendor in a supply chain, organizations typically have indirect relationships with nearly 14 times more fourth and fifth parties, according to The Cyentia Institute.

These numbers underscore the growth of interconnected risk. Each new supplier introduces dozens of unseen connections, and every one of those connections can become an attacker’s entry point. The impact can quickly cascade through shared platforms, APIs, and service providers, affecting multiple tiers of partners and customers.

The MOVEit breach of 2023 is a prime example. What began as a single vulnerability in one file transfer application rapidly spread across thousands of organizations, from banks and universities to government agencies. Many of those affected never had a direct contract with the compromised vendor.

Why Traditional Third-Party Risk Assessments Are Failing

For many organizations, third-party risk management still relies on the same tools and tactics used a decade ago—static checklists, self-reported questionnaires, and periodic audits. These methods were designed for a slower, more predictable vendor landscape. Today, they’re simply outmatched by the size and interconnectivity of modern supply chains.

Vendor questionnaires and checklists are only as good as the answers provided. Too often, the information is outdated, incomplete, or inaccurate, leaving security teams with a false sense of assurance. These assessments might capture what a vendor’s security looked like at a single moment in time, but attackers don’t wait for your next scheduled check-in. Every day between audits is another opportunity for adversaries to exploit newly discovered vulnerabilities or misconfigurations.

Static assessment programs also lack the scale and speed required to monitor hundreds or thousands of vendors effectively. As the vendor ecosystem expands, traditional approaches simply can’t keep pace with the dynamic nature of today’s threat environment.

The data underscores just how strained these legacy methods have become:

These numbers reveal a troubling paradox: organizations are spending more time than ever assessing vendors but gaining less clarity than ever in return. Without continuous, intelligence-led visibility, even the most diligent third-party risk programs are operating one step behind and measuring compliance rather than managing risk.

Shifting from Assessment to Intelligence: A Better Approach

Traditional third-party risk assessments expose the limits of hindsight. Intelligence-led monitoring delivers the advantage of foresight.

Static questionnaires stop at the vendor’s last self-reported status, which quickly becomes obsolete when adversaries move by the hour. An intelligence-based approach, by contrast, looks outward to live signals, behavioral patterns, and threat activity that reflect a vendor’s true security posture in real time.

The core shift is from assessment to intelligence.

This change is more than a process upgrade; it’s an evolution in how organizations manage supply chain security. Continuous, intelligence-led monitoring replaces static snapshots with ongoing, data-driven visibility across every tier of the vendor ecosystem.

By ingesting indicators from the open web, dark web, and technical telemetry, organizations can identify vulnerabilities or emerging exploit chatter as they happen—not months after the fact. The advantages are clear:

FAQs

What is considered a third-party risk?

A third-party risk is any potential threat to your organization's security, finances, or reputation posed by an external vendor, supplier, partner, or contractor who has access to your data, systems, or networks. This includes risks like data breaches, operational disruptions, and compliance violations originating from your supply chain.

What are the main types of third-party risk?

The main types include cybersecurity risk (data breaches, malware), operational risk (service disruptions), compliance risk (violating regulations like GDPR or CCPA), reputational risk (damage to your brand by association), and financial risk (revenue loss, regulatory fines).

How often should third-party risk assessments be conducted?

While traditional best practice was to conduct assessments annually, the current threat landscape demands a shift to continuous monitoring. Relying on annual, point-in-time assessments leaves significant security gaps where a vendor's risk posture can change without you knowing.

How does Recorded Future help with third-party risk assessment?

Recorded Future’s Third-Party Intelligence solution transforms risk assessment from a static, manual process into a dynamic, data-driven one. It provides continuous, real-time intelligence on your vendors' external security posture by monitoring millions of sources, including the dark web. This allows you to proactively identify threats, prioritize risks with objective scoring, and take action before a vulnerability impacts your organization.

What is the first step to improving a third-party risk management program?

The first step is to gain complete visibility into your entire vendor ecosystem. You cannot protect what you don't know you have. This involves identifying every third party and fourth party with access to your data or systems and then beginning the process of prioritizing them based on their level of access and criticality to your operations.
