The EU Cyber Resilience Act (CRA), set to take effect in 2026, introduces new compliance requirements aimed at enhancing the cybersecurity of AI systems. Companies developing or deploying AI solutions, particularly those in the AI supply chain, will need to adapt quickly to meet these legal obligations. The CRA sets stringent guidelines for the entire AI ecosystem, including AI software, hardware, and data, which means businesses must ensure all AI-related activities are secure, transparent, and compliant.

In this article, we’ll explore the key aspects of the EU CRA, focusing on the AI Bill of Materials (AIBOM) and its implications for AI software supply chains. We’ll also provide a step-by-step checklist for auditing third-party large language models (LLMs) and explore the risks of “Shadow AI,” where employees use unmanaged AI tools. Understanding these critical aspects will help you ensure compliance, mitigate risks, and improve your AI security posture.
Understanding the EU Cyber Resilience Act and its Impact on AI
The EU Cyber Resilience Act (CRA) is designed to strengthen cybersecurity across all industries that deploy digital and AI technologies. Its goal is to protect sensitive data, ensure AI systems are robust against cyber-attacks, and prevent the misuse of AI technologies. The legislation introduces several key requirements, including the creation of an AI Bill of Materials (AIBOM).
An AIBOM is a comprehensive inventory of all components used in an AI system, from the hardware and software to the underlying data. This requirement ensures full transparency regarding the origin and integrity of AI components, enabling more effective risk management and security measures. For AI companies, this means an in-depth audit of every piece of software, data, and hardware involved in the development and deployment of AI solutions.
Why the AI Bill of Materials (AIBOM) Matters
The introduction of the AIBOM under the EU CRA is a critical move toward securing the AI supply chain. By mandating a detailed inventory of AI components, the EU aims to improve traceability and accountability. Companies will need to provide transparency into all third-party tools, libraries, and services integrated into their AI systems.
The AIBOM serves as a protective measure against supply chain attacks. These types of attacks involve exploiting vulnerabilities in third-party components to breach an AI system. By cataloging all materials, organizations can more easily identify and mitigate potential risks associated with third-party AI tools and services. Furthermore, this requirement facilitates compliance by ensuring that businesses can demonstrate a clear record of their software and hardware components during audits.
The Risks of Shadow AI in the Workplace
One of the growing challenges in AI security is the rise of “Shadow AI” – when employees use unauthorized or unmanaged AI tools for business operations. Shadow AI occurs when employees deploy third-party AI services or tools without oversight from the organization’s IT or cybersecurity teams. This poses several risks, including data leaks, loss of control over AI systems, and difficulty in tracking potential security breaches.
Employees may unknowingly use insecure AI solutions, jeopardizing both company data and compliance with the EU CRA. Shadow AI tools often lack the required security protocols, making them vulnerable to cyber-attacks and data breaches. This is especially concerning when these AI tools process sensitive company data or client information.
To mitigate the risks of Shadow AI, organizations should establish clear AI usage policies, ensure employee awareness, and implement centralized management for AI tools. By incorporating these measures, businesses can ensure that all AI systems, even those used by individual employees, meet the necessary cybersecurity standards.
How to Audit Third-Party AI Tools and Large Language Models (LLMs)
As AI systems become increasingly complex, many organizations rely on third-party tools and services to enhance their capabilities. Third-party LLMs, for example, are often used to power AI-driven applications in industries like finance, healthcare, and retail. However, integrating these models without conducting a thorough security audit can leave businesses vulnerable to cyber-attacks.
To ensure compliance with the EU CRA, organizations must audit any third-party LLMs used in-house. This involves verifying the security of the model’s training data, the integrity of the algorithms, and the transparency of its outputs. A comprehensive audit should also examine whether the third-party tool complies with the EU CRA’s cybersecurity requirements.
The audit process should follow these steps:
- Assess the AI Model’s Training Data: Ensure the training data used to develop the LLM is secure, properly sourced, and free from biases that could result in vulnerabilities.
- Evaluate the Model’s Security Framework: Check for built-in security measures such as encryption and access controls that protect against data breaches.
- Monitor Model Performance: Regularly monitor the AI system’s performance to detect any anomalies or security weaknesses.
- Review Supplier Compliance: Confirm that the third-party LLM provider adheres to the security standards required by the EU CRA, including the implementation of the AIBOM.
- Update and Patch Regularly: Ensure that all updates and patches provided by the third-party vendor are applied promptly to minimize security risks.
A Comprehensive Compliance Checklist for AI Supply Chain Security
To help businesses navigate the complexities of the EU CRA, we’ve compiled a comprehensive compliance checklist. This checklist will guide organizations through the necessary steps to ensure their AI supply chains meet the EU’s cybersecurity standards.
- Identify and Inventory All AI Components: Create an AIBOM that lists every hardware, software, and data component involved in your AI systems.
- Ensure Security of AI Training Data: Verify that the training data used by your AI models is secure, anonymized where necessary, and complies with data protection laws.
- Evaluate Third-Party LLMs: Conduct a security audit of all third-party AI tools and services integrated into your AI systems, ensuring they meet the EU CRA requirements.
- Monitor AI Systems for Security Vulnerabilities: Continuously monitor your AI systems for any signs of vulnerabilities or malicious activities.
- Establish Clear AI Usage Policies: Implement policies that govern how AI tools are used within your organization, particularly to prevent the rise of Shadow AI.
- Train Employees on AI Security: Provide regular training to employees on the importance of AI security and the proper use of AI tools to avoid the risks associated with Shadow AI.
The Future of AI Security Under the EU CRA
As AI continues to evolve, so too will the challenges of securing these complex systems. The EU Cyber Resilience Act sets a precedent for global AI security standards, and businesses must adapt to these evolving requirements to remain compliant and competitive.
Looking ahead, AI will play a central role in cybersecurity, with advanced models capable of identifying and neutralizing threats in real time. However, this also means that the responsibility of securing AI systems will become even more critical. The implementation of the AIBOM and the scrutiny of third-party AI tools will likely expand as AI becomes more integrated into everyday business operations.
To stay ahead of these developments, organizations must continuously assess and update their AI security practices. By following the guidelines set by the EU CRA and embracing robust cybersecurity strategies, businesses can future-proof their AI systems and ensure compliance in an increasingly regulated digital landscape.
