Manufacturing Third-Party Risk: Why TPRM Matters Even Without Heavy Regulation
Manufacturers may face less industry-specific regulation than healthcare or financial services, but their complex supplier ecosystems create significant third-party risk. Learn why manufacturers need risk-based TPRM, continuous supplier visibility, and stronger oversight of vendors with access to systems, data, production environments, and critical business processes.
Introduction
Manufacturing may not face the same level of industry-specific cybersecurity regulation as financial services or healthcare, but that does not make third-party risk less serious.
Manufacturers depend on a complex network of suppliers, contractors, technology providers, logistics companies, equipment vendors, managed service providers, and other partners, and a weakness anywhere in that ecosystem can create consequences inside the manufacturer itself.
Third-party risk management (TPRM) is the structured process of identifying, assessing, mitigating, monitoring, and managing the risks created by those external relationships throughout their lifecycle. For manufacturers, that means understanding which suppliers have access to systems, data, facilities, or production environments, determining which relationships matter most, and maintaining visibility as those relationships and their risk profiles change.
The numbers show why this deserves more attention.
Manufacturing Is Already a Prime Cyber Target
IBM's 2026 X-Force Threat Intelligence Index found that manufacturing accounted for 27.7% of cybersecurity incidents in 2025, making it the most attacked industry for the fifth consecutive year.
That makes manufacturing an attractive target on its own, but the industry's interconnected supply chain creates another route for attackers.
Manufacturers rarely operate with complete control over every system that supports production. Suppliers may remotely access equipment, contractors may connect to corporate or operational environments, software providers may integrate with internal applications, and logistics partners may exchange sensitive operational information.
The result is an environment where the security boundary extends well beyond the company's own network.
That matters because attackers do not always need to defeat the strongest defenses protecting a large manufacturer. They can look for a less-protected company that already has a trusted relationship with the target.
Black Kite's 2025 Manufacturing Report found that manufacturing ransomware attacks increased 9% year over year and that attackers were increasingly targeting smaller contractors to gain access to larger manufacturing ecosystems. Manufacturing accounted for 38.9% of ransomware victims among companies generating more than $1 billion in revenue.
The supplier can become the attack path.
The Third-Party Problem Is Already Measurable
This is not a theoretical concern.
Imprivata reported that 42% of manufacturers experienced a data breach or cyberattack involving a third-party vendor accessing their network during the previous 12 months. Of those incidents, 35% involved excessive vendor privileges.
At the same time, only 29% of manufacturing organizations reported having a strategy consistently applied across the organization to address privileged access and supply-chain risk.
Those numbers create a significant gap between dependence and oversight.
Manufacturers may know which companies they purchase from, but that does not necessarily mean they know which suppliers have network access, what systems those suppliers can reach, whether that access is still necessary, or whether the supplier's security posture has changed since the last assessment.
That distinction is at the heart of effective TPRM.
A supplier inventory tells an organization who it does business with. A mature TPRM program helps determine which relationships could actually create material operational, cybersecurity, compliance, or business continuity risk.
Your Suppliers May Have Vulnerabilities You Cannot See
The challenge becomes even more significant when looking beyond direct vendor relationships.
Black Kite analyzed 1,042 manufacturing companies in its 2025 Manufacturing Supply Chain Risk Report and found that 75% had critical vulnerabilities with a CVSS score of 8 or higher. Sixty-five percent had at least one vulnerability listed in the CISA Known Exploited Vulnerabilities catalog, meaning the weakness was already known to be actively exploited.
Those figures describe manufacturers themselves, but the same question should be applied to the companies connected to them.
- How many critical suppliers have known exploited vulnerabilities?
- Which suppliers have exposed systems?
- Which vendors have privileged access?
- Which contractors can connect remotely to production environments?
- Which suppliers would create a serious operational problem if they suddenly became unavailable?
- And perhaps most importantly, how would the security team know if the answer to any of those questions changed?
A traditional annual questionnaire cannot provide that level of visibility.
Third-Party Risk Extends Beyond Cybersecurity
Manufacturing also has a characteristic that makes supplier risk particularly consequential: downtime can become a physical business problem very quickly.
A compromised software provider can disrupt business applications. A compromised equipment supplier can create concerns around connected machinery. A logistics provider can interrupt shipments. A contractor with remote access can introduce an attack path into an environment that was otherwise well protected.
The financial consequences can be significant.
Sophos found that the average cost of recovering from a ransomware attack in manufacturing and production was $1.3 million in 2025, excluding ransom payments.
51% of organizations whose data was encrypted paid the ransom, with a median payment of $1 million.
Manufacturers therefore have to consider supplier cybersecurity in the context of operational resilience.
If a supplier can contribute to production downtime, delay shipments, disrupt engineering operations, expose intellectual property, or interrupt access to critical systems, that supplier represents more than a cybersecurity concern.
It represents business risk.
Third-Party Breaches Can Cascade Across the Supply Chain
The scale of third-party incidents is also changing.
Verizon's 2025 Data Breach Investigations Report found that third-party involvement appeared in 30% of breaches, twice the percentage reported the previous year. Among breaches involving third parties, 81% followed the System Intrusion pattern.
Black Kite's 2026 Third-Party Breach Report found that every verified third-party breach in its 2025 dataset affected an average of 5.28 downstream companies, the highest level the organization has recorded. The research identified 719 publicly named victim companies and estimated that approximately 26,000 additional companies were affected but not publicly named.
That creates a problem for manufacturers with large and interconnected supplier ecosystems.
A supplier does not have to be a massive strategic technology provider to create significant exposure. A regional logistics provider, specialist engineering firm, software vendor, equipment manufacturer, or managed service provider can become important if the relationship gives that company access to something critical.
Risk therefore needs to be evaluated in the context of the relationship, not simply the size or reputation of the supplier.
Annual Assessments Leave a Visibility Gap
Many TPRM programs still revolve around a familiar process: identify the vendor, send a questionnaire, review the responses, assign a risk rating, and repeat the process next year.
That process can establish useful baseline information, but it has an obvious limitation.
The supplier can change tomorrow.
A vendor can experience a breach, introduce a new subcontractor, change its technology stack, expose a new service, lose key security personnel, acquire another company, or modify its privileged access without any of those changes appearing in a questionnaire completed months earlier.
Black Kite's 2026 third-party breach research found that verified third-party intrusions were detected in a median of 10 days, while public disclosure occurred much later, with a median delay of 117 days.
The point is not that manufacturers should wait for a public breach announcement before acting. The point is that supplier risk can change faster than traditional review cycles can detect it.
That makes continuous visibility particularly important for critical and high-risk suppliers.
What Manufacturers Should Prioritize
Manufacturers do not need to wait for a new regulation before taking these steps.
Start by identifying every third party with access to corporate systems, operational technology, sensitive information, production environments, or critical business processes. Then determine which relationships could create the greatest operational impact if the supplier were compromised or became unavailable.
From there, establish risk-based tiers and apply deeper due diligence to the suppliers that matter most. Review privileged access, remote connections, data flows, subcontractors, incident notification obligations, business continuity arrangements, and security controls according to the actual risk of the relationship.
Most importantly, move beyond the assumption that supplier risk can be understood once a year.
A supplier's security posture is a moving target. TPRM needs to account for that.
Where TPRM Fits Into Manufacturing Cybersecurity
TPRM should not operate as a separate administrative function disconnected from cybersecurity, procurement, IT, operational technology, and business continuity.
Security teams need visibility into supplier access. Procurement needs to understand which relationships require additional security controls. Business owners need to understand the operational consequences of supplier failure. Risk and compliance teams need evidence that due diligence and remediation are actually being performed.
That requires a shared view of supplier risk.
A useful TPRM program connects those functions through a consistent lifecycle: supplier intake, risk tiering, due diligence, assessment, evidence collection, remediation, monitoring, reassessment, and offboarding.
Rules-based workflows can reduce repetitive administrative work while keeping accountable people involved in reviewing risk, resolving exceptions, escalating issues, and making decisions.
That distinction matters. Supplier assurance cannot be reduced to an automated score. A supplier's risk depends on what it does for the organization, what information it handles, what systems it can access, how critical the relationship is, and what would happen if the supplier failed.
The technology should help teams manage that process. It should not replace the judgment required to manage it.
Manufacturing Does Not Need More Regulation to Justify TPRM
The strongest reason for manufacturers to take third-party risk seriously is already visible in their operating model.
Manufacturing depends on suppliers.
Those suppliers increasingly connect to corporate systems, production environments, data, applications, and physical operations.
Attackers understand those connections.
The statistics show the consequences. Manufacturing remains one of the most targeted industries, third-party involvement is appearing in a growing share of breaches, and attackers are increasingly using smaller contractors and interconnected suppliers as paths toward larger organizations.
Regulation may eventually place additional requirements on manufacturers, but waiting for regulation misses the larger business issue.
A supplier does not need to be legally designated as a critical third party to become operationally critical.
The question manufacturers should be asking is simple: if a supplier were compromised tomorrow, which relationships could turn that incident into our problem?
Answering that question requires more than a vendor list and an annual questionnaire. It requires a living understanding of the third parties the business depends on, the access they have, the risks they create, and the changes that could increase that risk over time.
That is the purpose of modern third-party risk management.
Frequently Asked Questions
What is third-party risk management in manufacturing?
Third-party risk management is the process of identifying, assessing, mitigating, monitoring, and managing risks created by suppliers, contractors, technology providers, and other external organizations throughout the relationship lifecycle. In manufacturing, this can include cybersecurity, operational disruption, data exposure, business continuity, compliance, and supplier dependency risks.
Why does manufacturing need TPRM if the industry is not heavily regulated?
Regulation is only one reason to manage third-party risk. Manufacturers depend on large and interconnected supplier ecosystems, and a compromised or unavailable supplier can affect production, systems, data, logistics, or customer commitments. The operational consequences can justify strong TPRM even when a specific regulation does not require it.
How much third-party risk exists in manufacturing?
Imprivata reported that 42% of manufacturers experienced a data breach or cyberattack involving a third-party vendor accessing their network during the previous year. It also found that 35% of those incidents involved excessive vendor privileges.
Are manufacturing suppliers a target for attackers?
Yes. Black Kite found that manufacturing remained the number one ransomware-targeted industry for the fourth consecutive year in its 2025 research and reported that attackers were targeting smaller contractors to gain access to larger manufacturing ecosystems.
Is an annual vendor assessment enough?
Annual assessments can provide useful baseline information, but they cannot reliably capture material changes that occur between reviews. Critical and high-risk suppliers benefit from ongoing monitoring, reassessment when conditions change, and defined processes for remediation and escalation.
What should manufacturers monitor about their suppliers?
The answer depends on the relationship, but monitoring can include security vulnerabilities, exposed systems, leaked credentials, security incidents, changes in ownership, material changes in technology or access, regulatory issues, and other indicators relevant to the supplier's role and risk tier.
How does TPRM help with manufacturing resilience?
TPRM helps organizations identify suppliers that could affect critical operations, assess those relationships according to their actual risk, establish remediation and escalation processes, and maintain visibility throughout the relationship. This gives security, risk, procurement, and business teams a clearer understanding of where supplier disruption could affect the organization.
Conclusion
Manufacturing has spent years strengthening the security of its own environment while depending on thousands of companies outside that environment to keep the business running.
Those companies are part of the risk picture whether a regulation says so or not.
The manufacturers that build a current, risk-based view of their supplier ecosystem will be better positioned to identify weak links, reduce unnecessary access, respond to changing conditions, and protect the operations that keep the business moving.
Third-party risk management is no longer something manufacturers need to do because a regulator tells them to.
They need it because their business depends on other companies.
