Security teams often struggle to correlate large volumes of log data and derive immediate, actionable intelligence. This specialized n8n workflow solves this by acting as a powerful connector between traditional security monitoring tools (like Wazuh, implied by the context) and an advanced AI RAG (Retrieval-Augmented Generation) engine, NixGuard.

This setup allows the user to submit a query or security event to the n8n trigger, which then aggregates the contextual data, forwards it to the NixGuard API for intelligent analysis, and returns a summarized, actionable output. Using this n8n template ensures that complex security data processing is handled seamlessly, providing real-time insights without manual intervention.

This powerful n8n workflow executes through a series of logical steps designed to prepare data, interact with the NixGuard AI service, and clean the resulting output.

1. Trigger and Preparation: The workflow is initiated either by the Execute Workflow Trigger node (allowing external workflows, like a Wazuh alert handler, to invoke it) or potentially a chat-based n8n trigger (if enabled). The Prepare API Request Data n8n node then sets essential variables, including the apiKey and the security query (chatInput).


2. Data Unification: The Merge Input Data, Aggregate Security Data, and Combine Security Data n8n node steps consolidate all incoming variables into a single, unified JSON payload. The Code n8n node within this section ensures that disparate data sources (like security context and the query itself) are correctly formatted.


3. API Call: The Send Request to NixGuard API n8n node executes an HTTP POST request to the external RAG service endpoint (https://nix.thenex.world). It securely passes the API key and the formatted security prompt to the AI engine.


4. Response Handling: Upon receiving the raw response, the Parse NixGuard Response n8n node (a Code node) parses the response string into a usable JSON object.


5. Output Formatting: Finally, the Format API Response n8n node extracts the core insight (content), and the Prepare Final Output n8n node structures the result for easy consumption by the next step in the overall n8n workflow or the end user.

To deploy this security analysis n8n workflow, follow these steps:

1. Import the n8n Workflow: Copy the provided JSON data and import it directly into your n8n instance via the Workflows section ('New' -> 'Import from JSON').


2. Configure Credentials: Open the Prepare API Request Data n8n node (a Set node). You must securely input your NixGuard API key in the 'apiKey' assignment value. This is critical for authentication.


3. Set Up Trigger: The primary input is handled by the Execute Workflow Trigger n8n node. If you want to use this n8n workflow manually, you can execute it and provide sample input for testing.


4. Test the n8n Node Chain: Run the workflow using test data to ensure the Send Request to NixGuard API n8n node successfully connects and the subsequent parsing nodes correctly extract the security insights.


5. Integration: Connect this n8n trigger to your monitoring system (like a webhook from Wazuh or a scheduled n8n node polling alerts) to fully automate the process.

Execute Workflow Trigger: Acts as the entry point, allowing this automation to be called by another n8n workflow or process, ensuring flexibility in integration.
Prepare API Request Data (Set): Function: Defines and sets the necessary variables (apiKey, chatInput) required by the external API. Key Configuration: Contains placeholders for the sensitive apiKey and maps the incoming security query to chatInput.
Aggregate Security Data (Aggregate): Function: Collects and consolidates all data items generated by the preceding preparation and trigger steps into a single object, preparing it for unified processing.
Combine Security Data (Code): Function: Uses custom JavaScript to merge properties from all input data items, ensuring the final object passed to the API contains all required context.
Send Request to NixGuard API (HTTP Request): Function: Transmits the combined security query and API key to the NixGuard endpoint. Key Configuration: Uses POST method, targets https://nix.thenex.world, and includes required JSON headers and body parameters (apiKey, prompt).
Parse NixGuard Response (Code): Function: Converts the raw data string received from the API into a manipulable JSON structure. This custom n8n node logic is crucial for handling complex API responses.

• Prepare Final Output (Code): Function: Formats the cleaned security insight into a standardized output variable, ready for subsequent steps in the n8n workflow.
