The regulatory trilemma of AI-driven cybersecurity in the European Union: reconciling the AI Act, DORA, and fundamental rights
: The European Union has enacted two landmark frameworks that impose partially divergent obligations on financial entities deploying artificial intelligence (AI) in cybersecurity. The AI Act (Regulation (EU) 2024/1689) establishes a risk-based classification system subjecting AI systems to graduated transparency, explainability, and human-oversight duties.
