About Privent 2.0
Privent 2.0 is a dedicated runtime data control solution designed specifically to secure n8n workflows. In standard AI workflows, agents frequently transmit raw, sensitive information—including emails, database records, API keys, and secrets—to Large Language Models (LLMs) on every run. While n8n's native Guardrails node can redact this information, that redaction is permanent, preventing the workflow from reclaiming the original data once processed.
Privent 2.0 resolves this issue by tokenizing PII and secrets before they reach the LLM, and then safely reversing the tokenization at a trusted sink to restore the original data. As an Official n8n Integration Partner, it is built for production teams running complex agent workflows that cannot afford a single leaked record. For teams requiring strict data boundaries and absolute compliance, Privent 2.0 also features a Local mode that runs entirely offline.
Pros of Privent 2.0
- Tokenizes PII and secrets before they reach LLMs, avoiding permanent data loss
- Safely reverses tokenization at a trusted sink to restore original data
- Offers a Local mode that runs fully offline
- Official n8n Integration Partner built specifically for production workflows
Cons of Privent 2.0
- Focuses specifically on n8n workflows, which may limit teams using other orchestration platforms
- Requires configuring a trusted sink to reverse the tokenization process

How does Privent 2.0 differ from n8n's native Guardrails node?
