When automating with AI, security and compliance must be front and center. n8n provides tools and
patterns to help secure workflows, but you should follow these core practices:
• Secrets management: Never hard-code API keys. Use environment variables or a secrets manager.
Rotate keys regularly.
• PII handling: Identify and redact personally identifiable information before sending data to third
party AI APIs. Consider on-premise or private deployments if your data is sensitive.
• Audit and logging: Keep detailed logs for automated actions and model calls (with access controls)
so you can trace decisions.
• Access control: Limit who can edit or execute workflows in n8n; use role-based permissions and
separate dev/test environments.
• Data minimization: Send only what’s necessary to external APIs. Use hashing or tokenization where
possible.
• Compliance frameworks: Map your automation to relevant regulations (GDPR, HIPAA, etc.) and
consult legal when automating sensitive processes.
