n8n Integration

Real-Time Protection for n8n AI Workflows

Scan every payload moving through your workflow for conversation history and intent, then assign a security classification that routes execution branches for real-time protection against multilingual, multimodal, and multi-turn attacks at sub-99ms latency, for safe and reliable AI automations at scale.

What WonderFence adds to n8n

n8n gives you the agent. WonderFence gives you the controls — dynamic guardrails, granular policies, and full runtime visibility on top of what n8n ships by default.

Policies That Match Your Business

n8n's default guardrails are generic. WonderFence lets you enforce policies that reflect your compliance rules, brand voice, and risk tolerance — preconfigured options out of the box, or write your own. Apply them organization-wide or per-agent.

Defense Against Prompt Injection and Tool Misuse

Stop jailbreaks, data exfiltration, and tool abuse before they hit your databases, APIs, or customers. WonderFence catches malicious patterns that get past n8n's default guardrails.

Visibility Into What Agents Actually Do

n8n shows you what you built. WonderFence shows you what your agents are doing in production — every prompt, tool call, and output, plus drift, policy violations, and unexpected behavior as it happens.
