The EU AI Act and the GDPR ask companies to manage risks, restrict which data an AI system may see, and be able to explain what the system does. The AI Act entered into force on August 1, 2024 and has applied since August 2, 2026, with some exceptions. It sorts AI systems by risk. According to the European Commission, the vast majority of AI systems currently used in the EU fall into the lowest category, with minimal or no risk. Since February 2, 2025, every business that uses AI must also make sure its employees know enough to work with it responsibly. For a small or medium-sized business, security and privacy come down to ordinary questions: who gets access, which data goes to a model, and what happens when something breaks. The four measures above line up with exactly those questions.
