Supply Chain Cyber Security Assessment & Third-Party Risk Management
Assess third-party cyber risks, uncover supplier security gaps and strengthen resilience across your supply chain.
What Is Supply Chain Cyber Security?
Supply chain cyber security is the process of identifying, assessing and managing cyber risks introduced by suppliers, vendors and third parties.
It focuses on protecting your organisation from risks originating outside your direct control, including:
- Access Risk – Suppliers with privileged access to systems or data
- Operational Risk – Third parties critical to business continuity
- Software Supply Chain Security Risk – Vulnerabilities in applications, integrations or code dependencies
A structured approach combines vendor risk assessment cyber security, governance and continuous monitoring to reduce exposure and improve resilience.
Reduce Third-Party Risk. Strengthen Supplier Cyber Resilience.
Modern organisations are only as secure as the suppliers, partners and service providers they rely on.
As ecosystems expand across cloud, SaaS and outsourced services, supply chain cyber security and third-party risk management have become critical to operational resilience, compliance and board assurance.
CyberOne delivers structured supply chain security assessments and TPRM consulting services that help you identify, prioritise and reduce third-party cyber risk. We turn fragmented supplier checks into a measurable, risk-led third-party risk management program.
Common Signs Your Supply Chain Risk Is Too High
Limited Supplier Visibility
You lack a clear view of which vendors introduce the highest cyber risk.
Inconsistent Vendor Security Assessment
Assessments vary by team, lack standardisation or rely only on questionnaires.
Expanding Third-Party Dependencies
Cloud, SaaS and outsourced services are growing without aligned governance.
Weak TPRM Framework
No structured third party risk management program or defined operating model.
Low Board Confidence
Leadership lacks clear reporting on supplier cyber resilience and exposure.
How to Assess Third Party Cyber Risk
A structured third party cyber risk assessment follows a clear, risk-based methodology:
1. Supplier Identification & Segmentation
Classify suppliers based on criticality, access and business impact
2. Vendor Security Assessment
Evaluate controls, maturity and exposure using a consistent framework
3. Risk Scoring & Prioritisation
Rank suppliers based on likelihood and business impact of compromise
4. Remediation & Risk Treatment
Define actions to reduce risk across high-priority suppliers
5. Continuous Monitoring & Review
Maintain ongoing assurance through regular reassessment and governance
CyberOne’s Supply Chain Security Assessment Process
CyberOne provides supply chain cyber security consulting that goes beyond checklists to deliver measurable outcomes.
Supply Chain Discovery
Identify critical suppliers, dependencies and emerging fourth party risk management exposure. This provides a clear view of your extended supply chain and where risk may exist. It also helps uncover indirect dependencies that are often overlooked. With this insight, you can begin to prioritise risk effectively.
Third Party Cyber Risk Assessment
Assess vendors using a consistent, risk-based methodology. This ensures supplier evaluations are aligned to business risk and not treated as a tick-box exercise. It also provides a comparable view of security posture across all vendors. Over time, this supports better decision-making and risk tracking
Risk Segmentation
Prioritise suppliers based on criticality, access and business impact. This allows you to focus effort where it will have the greatest impact on resilience. It also ensures that high-risk suppliers are managed more closely. Segmentation helps avoid spreading resources too thinly across low-risk vendors.
TPRM Framework Consulting
Design a scalable TPRM framework consulting model aligned to your organisation. This defines how third-party risk is governed, managed and embedded into business processes. It also ensures consistency across onboarding, assessment and review. A strong framework enables long-term scalability and control.
Remediation Roadmap
Deliver a practical plan to reduce supplier cyber risk over time. This turns assessment findings into clear, prioritised actions. It also ensures accountability for addressing identified risks. A well-defined roadmap helps maintain momentum and demonstrate measurable progress.
Ongoing Assurance
Support continuous improvement and supplier cyber resilience. This ensures supplier risk is actively managed rather than reviewed periodically. It also enables you to respond to changes in risk posture, new threats or evolving business needs. Over time, this builds a more resilient and adaptive supply chain.
