FAQ
How does this AI Security Gateway integrate with my LLM workflow?
It works as a lightweight webhook/middleware in n8n. You send your incoming input text to this gateway, it redacts sensitive data and scores the risk, and then returns clean text for your LLM pipeline
What types of sensitive data (PII) can it redact?
Out of the box, it automatically detects and masks Emails, 10-digit National IDs, Credit Cards, API Keys, Passwords, AWS Secrets, SSNs, and IP addresses using numbered tokens (like [EMAIL_1]).
Can I add custom detection rules for my specific business data?
he workflow uses modular security rules that can be extended with additional detection patterns
Do I need a paid n8n plan to use this?
No, this workflow works seamlessly on both self-hosted (free) n8n instances and n8n Cloud plans.
