## Short Answer

n8n is useful for prototypes and lightweight automation, but building a workflow is not the same as safely running a client system. Once a workflow holds API keys, CRM data, email access, payment records, customer data, or internal documents, updates, credentials, monitoring, backups, and incident response become real costs.

## Best For

- Low-risk internal workflows such as lead sorting, content drafts, meeting summaries, reminders, and non-sensitive reports.
- Projects with a clear deployment model, least-privilege accounts, logs, backups, and response-time boundaries.
- Clients willing to pay separately for setup and monthly maintenance.

## Avoid If

- The workflow touches payments, invoices, payroll, regulated data, or production databases.
- The client wants master accounts, no staging environment, no audit logs, and a one-off setup fee.
- Self-hosting is treated as a cheap shortcut without updates, isolation, backups, and monitoring.

## Minimum Test

1. Choose one low-risk workflow.
2. Use dummy or non-sensitive data.
3. Run it for 14 days with a dedicated low-privilege account.
4. Track runs, failures, manual intervention, log quality, credential rotation, and recovery steps.
5. Test adversarial text to confirm untrusted input cannot trigger high-impact actions.

## Stop-Loss Signals

- The client asks for unrestricted code or HTTP nodes in production.
- No log access, staging environment, rollback path, or credential-recovery process exists.
- AI agents are connected to payments, bulk email, customer privacy, or internal approvals under a low one-time fee.
- Trial failures require frequent manual rescue.

## Data Boundary

Security advisories and research describe risk models, not guaranteed incidents. Always verify current n8n versions, deployment mode, official advisories, customer data type, and contract scope.
