AI-Powered Security Analysis for n8n with Google Gemini and n8n audit API

Generate a security audit report from an n8n instance to a web form This workflow provides a deep-dive security assessment of an n8n instance using the native Audit API and AI analysis.

Who’s it for This template is for n8n administrators and DevSecOps engineers who need to maintain a high security standard across their automation infrastructure. It is particularly useful for teams managing self-hosted instances with multiple users.

How it works The workflow triggers via an n8n Form where you provide your instance URL and API key. It calls the official n8n Audit API to scan for five categories of risk: instance settings, credentials, database (SQL injection), nodes, and filesystem access. A Code node parses this data, which is then analyzed by Google Gemini to create a prioritized remediation plan.

Requirements n8n version v1.0 or higher. A Google Gemini API Key. An n8n API Key with 'Audit' scope permissions.

How to set up Create a Google Gemini API credential in n8n. Ensure your n8n API key has the correct scopes. Execute the workflow and enter your credentials into the trigger form.

How to customize the workflow You can easily swap the Google Gemini node for OpenAI or Anthropic. You can also add a 'Send Email' or 'Slack' node at the end to automatically route the report to your security channel instead of just viewing it in the browser.
