Cybersecurity in the Supply Chain: Identifying and Systematically Managing Risks
“Cyber insecurity” is one of the biggest risks and affects the entire supply chain. In this article, you will learn why and how to implement cybersecurity across your supply chain.
In its latest Global Risks Report, the World Economic Forum (WEF) ranks “cyber insecurity” among the most significant global risks (ranked 6th in the short term). According to the Hackett Group, it is even the number one risk factor for procurement leaders. At the same time, the new NIS2 directive makes one thing clear: cybersecurity concerns the entire supply chain and does not end at a company’s own factory gates. It is therefore time to take a closer look at cybersecurity in the supply chain and to consistently address cyber risks from a procurement and supply chain perspective.
Key takeaways on cybersecurity in the supply chain
What is cybersecurity in the supply chain?
Cybersecurity in the supply chain refers to all measures that ensure IT security and information security among external service providers, suppliers, and third parties that have access to systems, data, or critical processes. It therefore covers the systematic protection of the entire supply chain against digital threats.
Why is cybersecurity in the supply chain important?
Modern supply chains are highly interconnected: companies collaborate with cloud providers, IT service providers, logistics companies, consultancies, outsourcing partners, and many other actors. Data flows across system boundaries, external partners access internal business applications, and critical processes depend on third parties. In globally connected supply chains in particular, this creates new digital attack surfaces.
This interconnectedness is exactly what makes supply chains vulnerable to cyberattacks. A single weak point—such as a poorly secured service provider with VPN access or a software supplier with inadequate security standards—may be enough to give attackers access to a company’s systems. This so-called third-party cyber risk is now one of the main drivers behind security incidents in companies and therefore a core challenge for cybersecurity in the supply chain.
As Bitkom President Dr. Ralf Wintergerst puts it:
„Attackers look for the weakest link. Even in highly protected companies, that weak point is often a less protected supplier. (…) Improving cybersecurity therefore requires raising awareness among business partners across the supply chain, agreeing on protective measures, and implementing them together. “
The consequences range from operational disruptions and financial losses to severe reputational damage. Cybersecurity in the supply chain therefore means that not only a company itself must be resilient, but the entire supply chain ecosystem in which it operates.
The challenges of cybersecurity in the supply chain
In theory, it is clear: supply chain risks—including those related to IT security—must be systematically identified and managed. In practice, however, the challenge rarely lies in a lack of willingness, but rather in missing structures. This is exactly where the complexity of cyber risk management becomes apparent.
Typical challenges:
- Lack of transparency regarding relevant suppliers
Many companies do not have a clear overview of which suppliers are particularly critical from an IT perspective. System access, data flows, or dependencies are often not centrally documented. As a result, it remains unclear where an attack would cause the most damage. - Different maturity levels among suppliers
While some partners can demonstrate established security standards and certifications, others have little to no documented measures or defined security levels. This heterogeneity makes consistent risk and measure assessment difficult and highlights that there is no one-size-fits-all solution. Instead, dedicated supplier engagement discussions are required. - Manual and unstructured data collection
Information about security measures is often collected via email, Excel files, or individual questionnaires. Such manual risk assessments are time-consuming, error-prone, and not scalable—especially when managing large supplier portfolios. - Outdated information
Once collected, data is rarely updated regularly. As a result, changes—such as updates in a supplier’s IT landscape, security incidents, or new certifications—often go unnoticed. - Limited auditability in case of reviews
Even when measures are implemented, they are often not documented consistently. In the event of audits, regulatory reviews, or security incidents, companies lack a central, reliable overview.
These points highlight a key insight: cybersecurity in the supply chain cannot be addressed through isolated, one-off measures. What is needed are structured, repeatable, and traceable risk assessments that create transparency and enable continuous risk management.
Cyber risk management as the foundation for cybersecurity in the supply chain
Effectively addressing cyber risks in the supply chain requires a holistic approach. Cybersecurity in the supply chain is not an isolated IT topic but part of strategic supply chain risk management.
Key considerations include:
- Structured supplier risk management
Suppliers should not only be assessed based on price, quality, and delivery capability, but also on their cyber risk profile. This includes standardized risk assessments, clear criteria, and consistent evaluation frameworks. - Binding security requirements for third parties
Security standards—such as requirements for access control, encryption, incident management, or patch management—should be contractually defined. This is the only way to make cybersecurity a fixed component of collaboration. - Clear communication and escalation paths
In critical situations, every minute counts. Companies need defined contacts, reporting channels, and processes to quickly identify, assess, and jointly address incidents involving suppliers. - Regular review and updates
Threat landscapes evolve, as do IT environments, supplier relationships, and risk assessments. Cyber risks therefore need continuous monitoring, and evaluations must be updated regularly—not only once during supplier onboarding.
How can cybersecurity in the supply chain be ensured?
How can companies take concrete steps to systematically manage cybersecurity as a supply chain risk? A step-by-step approach has proven effective:
1. Identify and prioritize relevant suppliers, access points, and dependencies
The first step is to create transparency regarding which external partners are truly critical from a cybersecurity perspective. The decisive factors are not only contractual relationships but also actual system access, data flows, and operational dependencies—meaning the real potential impact on availability, integrity, and confidentiality. This helps segment the truly relevant partners and dependencies in a targeted way:
- Centrally document all external system access points (e.g., VPNs, APIs, cloud integrations)
- Classify suppliers into criticality levels based on their access and data impact
- Identify particularly sensitive or business-critical dependencies (single points of failure)
- Consistently reduce unnecessary or over-privileged access (principle of least privilege)
2. Continuously monitor risks and ensure transparency
Cyber risks in the supply chain evolve continuously—due to new threats, changing IT environments, or adjustments in collaboration. Assessments should therefore not only be updated regularly but also be made manageable across the entire supplier portfolio:
- Establish regular reassessments for critical suppliers
- Conduct event-driven reassessments in case of incidents or significant changes
- Introduce aggregated risk dashboards for portfolio management
- Continuously monitor central KPIs (e.g., open high-risk findings, remediation rate, assessment coverage, security monitoring)
- Ensure compliance with regulatory requirements, including documentation for NIS2 compliance
3. Document measures and ensure auditability
All assessments, decisions, and measures should be documented centrally. This makes it possible to demonstrate
- that risks were identified and addressed,
- which requirements were defined for suppliers,
- how incidents were handled.
Such auditability is not only important for audits and regulatory requirements, but also for internal confidence in the company’s security approach.
Conclusion: Rethinking cybersecurity – from supply chain risk to strategic management
Cybersecurity today goes far beyond firewalls, virus scanners, and internal IT policies. Companies that want to protect their business must consider the entire supply chain—from selecting critical service providers and defining clear requirements and contracts to conducting recurring assessments and maintaining proper documentation.
The good news: Companies that consistently extend their cybersecurity strategy to include the supply chain gain not only resilience but also control. They know where their biggest dependencies lie, can prioritize risks, and are able to respond faster when incidents occur.
In short: cybersecurity starts within your company—but it does not end at your factory gates.
