Supplier Cybersecurity Assessment: Key Criteria and ISO Expertise

In 2024, cyberattacks have reached a critical level with a projected global cost of $9.5 trillion. The recent Change Healthcare breach, compromising the data of 190 million people, perfectly illustrates the catastrophic risks tied to the supply chain.
Faced with this threat, where a new attack occurs every 11 seconds, rigorous supplier cybersecurity assessment has become a strategic pillar of third-party risk management. This structured approach, based on international standards, enables companies to secure their supply chain while meeting growing regulatory demands.
Data protection and business continuity now require a structured approach to partner security, with the average cost per incident reaching $4.88 million.
Key Criteria for an Effective Assessment
Cybersecurity Audit
Assessing maturity level and performing a cybersecurity audit forms the foundation of supplier evaluation. Beyond a simple check, it’s a thorough analysis based on precise criteria.
Protection Measures
- Security infrastructure and access controls
- Protection of sensitive and confidential data
- Securing cloud environments
Incident Management
- Documented incident response procedures
- Dedicated cybersecurity team
- Regularly tested business continuity plans
Compliance and Certifications
- ISO 27001/27701 compliance
- Alignment with GDPR requirements
- Ongoing updates to security protocols
The audit provides a detailed view of the supplier’s security status and flags key risk areas.
Certifications and Compliance
Holding recognized certifications such as ISO 27001 is a strong signal of supplier reliability. These attest to compliance with international information security management standards. Beyond ISO 27001, some companies may require ISO 27701, which adds a data privacy dimension. Both should be part of document collection.
Compliance with local and international regulations, like the European GDPR, is also essential. A compliant supplier reduces financial and legal risks, ensuring better overall security.
Cybersecurity Maturity
Evaluating a supplier’s cybersecurity maturity means understanding how deeply security practices are embedded in their operations. Key indicators include:
- Existence of a dedicated cybersecurity team
- Regular employee training
- Implementation of strong security policies
The more mature a supplier is, the lower the risk for your company.
Managing Supplier Risk
Risk Scoring
Managing supplier-related risk requires a holistic approach that incorporates cybersecurity and business continuity. Total supply chain attack costs are projected to reach USD 60 billion in 2025, reinforcing the need for robust strategies.
Risk Categories to Assess
- Financial and operational risks
- Security and compliance risks
- Reputational and strategic risks
Access Controls
Enforcing strict access controls is critical:
- Least privilege principle
- Multi-factor authentication (MFA)
- Network segmentation of access rights
Risk management requires evaluating both the probability of an attack and its potential consequences to prioritize resources and define targeted action plans.
Business Continuity
To ensure viable partnerships, business continuity must be maintained even during cyberattacks. Suppliers should demonstrate robust disaster recovery plans and response capabilities:
- IT backup and data recovery plans
- Regular plan testing
- Ability to promptly inform clients during incidents
These mechanisms help minimize impact and restore normal operations swiftly.
