| Azure OpenAI | ✅ EU region option | ✅ | ✅ | ✅ Good |
| Anthropic API | ❌ US only | ✅ (Business) | ✅ | ⚠️ Needs SCCs |
| OpenAI API | ⚠️ EU option available | ✅ (Business) | ✅ | ⚠️ Check config |
| DeepSeek | ❌ China | ❌ Unknown | ❌ Unknown | ❌ Avoid for PII |

What “GDPR compliant” actually means
For an AI API to be GDPR compliant, you need:
- Legal basis for processing (legitimate interest or consent)
- Data Processing Agreement (DPA) with the provider
- Transfer mechanism if data leaves the EU (SCCs, adequacy decision)
- No training on your data (or explicit consent for it)
- Data retention limits that match your privacy policy
Whichever provider you choose, make sure your API keys are stored and rotated securely — see our guide on how to secure AI API keys for best practices.
The safest path for EU companies
Tier 1 — Zero risk: · Best VPNs for Developers
- Self-hosted models via Ollama
- No data transfer, no DPA needed, automatic compliance
Tier 2 — Low risk: · Best VPNs for Developers
- Mistral API — EU-native, DPA included
- Google Vertex AI with EU region — established GDPR framework
Tier 3 — Medium risk (needs paperwork): · Best VPNs for Developers
- Anthropic API with Business DPA + SCCs
- Azure OpenAI with EU region + DPA
Tier 4 — High risk (avoid for sensitive data): · Best VPNs for Developers
- Consumer subscriptions (ChatGPT Plus, Claude Pro)
- Chinese providers without clear data policies
- Free tiers without business terms
