The EU AI Act and Cybersecurity: What Your Business Needs to Know

The EU AI Act isn’t just about ethics and transparency — it has real cybersecurity obligations. Here’s what matters for your business.

The EU AI Act is the world’s first comprehensive regulation of artificial intelligence. While most of the conversation has focused on high-risk AI systems, bias, and transparency, there’s a cybersecurity dimension that many businesses are overlooking.

If you develop, deploy, or use AI systems in the EU, you need to understand how the AI Act intersects with your existing cybersecurity and compliance obligations.

The Risk-Based Approach

The AI Act classifies AI systems into four risk categories:

Unacceptable risk — Banned outright. Includes social scoring by governments, real-time biometric surveillance (with limited exceptions), and AI that exploits vulnerabilities of specific groups.

High risk — Permitted but heavily regulated. Includes AI used in critical infrastructure, education, employment, essential services, law enforcement, and migration. Also includes AI systems that are safety components of products covered by existing EU legislation.

Limited risk — Transparency obligations. Includes chatbots (must disclose they’re AI), deepfakes (must be labelled), and emotion recognition systems.

Minimal risk — No specific obligations. Includes spam filters, AI in video games, and most business productivity tools.

The Cybersecurity Requirements

For high-risk AI systems, Article 15 requires a level of cybersecurity that is “appropriate to the risks.” Specifically:

• Resilience against attacks — AI systems must be designed to be resilient against attempts by unauthorised third parties to alter their use, outputs, or performance by exploiting system vulnerabilities • Protection against data poisoning — training data integrity must be protected • Protection against model manipulation — adversarial attacks, model extraction, and inference attacks must be addressed • Logging and traceability — system must log events to enable monitoring and post-incident investigation • Human oversight mechanisms — humans must be able to understand, supervise, and override AI decisions

Where AI Act Meets Your Existing Frameworks

The AI Act doesn’t exist in isolation. Here’s how it connects to the frameworks you may already be working with:

GDPR — If your AI processes personal data, GDPR still applies in full. The AI Act adds transparency requirements on top of GDPR’s existing data protection rules. Automated decision-making under GDPR Article 22 now has a parallel set of obligations under the AI Act.

NIS2 — If your AI system is part of critical infrastructure or essential services, NIS2’s cybersecurity requirements apply to the systems hosting and supporting the AI, while the AI Act governs the AI system itself.

ISO 27001 — Your ISMS should already cover the information assets associated with AI systems. The AI Act adds specific requirements around training data integrity, model security, and system resilience that your risk assessment should capture.

DORA — If you’re using AI in financial services (algorithmic trading, credit scoring, fraud detection), DORA’s ICT risk management and resilience testing requirements apply alongside the AI Act.

What SMBs Should Do Now

  1. Audit your AI usage — Document every AI system you develop, deploy, or use. Classify each against the risk categories.
  2. Assess high-risk systems — If any of your AI systems fall into the high-risk category, start preparing for the cybersecurity and documentation requirements.
  3. Update your risk assessment — Add AI-specific threats (data poisoning, model manipulation, adversarial attacks) to your existing cyber risk register.
  4. Check your supply chain — If you use third-party AI services, understand whether they’re classified as high-risk and what obligations flow to you as a deployer.
  5. Align frameworks — Don’t treat the AI Act as a standalone exercise. Map it to your existing GDPR, NIS2, or ISO 27001 controls to avoid duplicating work.
