Tamper-evident, compliance-grade logs of every agent action in n8n agents — without rewriting your code, without adding a proxy to the request path.
The problem
n8n is great at what it does, but production-grade audit logging is bring-your-own. Most teams discover this when the first production incident hits, the first OpenAI bill arrives, or the first auditor asks for evidence.
Specifically:
- No native cost visibility per workflow or AI Agent node
- AI Agents can call HTTP Request against production with no review
- Workflows that loop on a failing tool can rack up $1000s before detection
How Prefactor solves it
Prefactor wraps your n8n Workflow and adds audit logging as a runtime layer. Specifically:
- SOC 2 evidence collection
- EU AI Act Article 12 record-keeping
- ISO 42001 documentation lifecycle
- auditor-ready exports
- incident forensics
Install and integrate
Install via n8n Community Nodes// In n8n:
// Settings → Community Nodes → install n8n-nodes-prefactor
// Add "Prefactor: Wrap Workflow" node at workflow start
// Or use webhook integration for n8n Cloud (no install)Specific use cases
- Soc 2 evidence collection
- Eu ai act article 12 record-keeping
- Iso 42001 documentation lifecycle
- Auditor-ready exports
- Incident forensics
FAQ
Does this add latency? Per-span instrumentation adds ~2-5ms. Telemetry ships asynchronously. No synchronous network call in the agent's hot path unless you enable blocking policy enforcement.
Can I configure this per-agent? Yes. Audit Logging settings are per-agent — different agents can have different policies, sampling rates, retention, etc.
Is this compatible with other observability tools? Yes. Prefactor exports OpenTelemetry; works alongside Datadog, Langfuse, LangSmith, and others.
