Endpoint Security Risk Aggregation and Reporting - n8n Workflow

Security analysts needing automated risk aggregation and centralized reporting.
IT operations teams who use n8n templates for system monitoring.
DevOps professionals requiring continuous security data correlation.
Anyone looking to build a complex data processing n8n workflow using custom logic and scheduled execution.

Maintaining endpoint security requires correlating massive amounts of data from multiple siloed systems, such as Endpoint Detection and Response (EDR) platforms, vulnerability scanners, and File Integrity Monitoring (FIM) tools. This specialized n8n workflow solves this correlation problem by running a daily scheduled n8n trigger. The workflow efficiently executes concurrent HTTP requests to pull raw security logs. These disparate signals are then merged and processed through a custom function n8n node, the 'Risk Score Calculator,' which applies specific logic to normalize and aggregate the input into a unified, actionable endpoint risk score. Finally, this critical metric is written to a Google Sheet using an optimized n8n node for centralized security dashboards and long-term trending, providing essential security reporting capabilities directly through your automated n8n solution.

This powerful security aggregation process is structured logically within the n8n environment:

1. Trigger Initiation: The entire process is initiated by the Cron Trigger – Daily n8n trigger, ensuring the risk assessment runs reliably once every day.


2. Parallel Data Collection: Upon activation, three parallel HTTP Request n8n node instances fire simultaneously: Get EDR Logs, Get Vulnerability Data, and Get File Integrity Logs. These retrieve essential raw security signals from external APIs.


3. Initial Merging: The Merge Endpoint Signals n8n node combines the EDR logs and the Vulnerability Data results into a single collection.


4. Final Data Aggregation: The Merge + FIM Logs n8n node then combines the result of the previous merge with the collected File Integrity Logs, ensuring all necessary input data is present.


5. Risk Calculation: The fully combined security data is routed to the custom Risk Score Calculator n8n node (a Function node). This crucial step executes proprietary JavaScript logic to transform the raw security data into a standardized numerical risk score for each monitored endpoint.


6. Reporting: The calculated scores are then sent to the final Google Sheets n8n node, where the data is appended or updated in a specified spreadsheet for centralized monitoring, completing the daily automated n8n workflow cycle.

To deploy this comprehensive n8n workflow template, follow these steps:

1. Import: Copy the provided JSON code and paste it into your n8n instance using the 'New' -> 'Import from JSON' option.


2. Cron Trigger: The Cron Trigger – Daily n8n trigger is pre-configured to run once a day, but you can adjust the schedule as needed.


3. HTTP Request Credentials: Configure the three HTTP Request n8n node instances (Get EDR Logs, Get Vulnerability Data, Get File Integrity Logs). You will need to input the correct API URLs, authentication credentials (often API keys or Bearer tokens), and request headers required by your external security platforms.


4. Google Sheets Setup: Create a new credential for the Google Sheets n8n node if you haven't already. Ensure the service account associated with the credential has 'Editor' or 'Writer' permissions on your target spreadsheet where the risk scores will be stored.


5. Function Node Customization: The Risk Score Calculator n8n node contains placeholder code. You must input your specific risk scoring logic (custom JavaScript) to correctly process and aggregate your security signals according to your organization's risk matrix.


6. Activate: Save the n8n workflow and toggle the 'Active' switch.

Cron Trigger – Daily (n8n trigger): Sets the execution schedule for the entire automation, ensuring the security risk assessment runs automatically every day.
Get EDR Logs / Get Vulnerability Data / Get File Integrity Logs (HTTP Request n8n node): These nodes are essential for integrating with external security platforms. They retrieve the raw security data necessary for the assessment. Key configuration involves setting the correct external API endpoints and necessary authentication.
Merge Endpoint Signals / Merge + FIM Logs (Merge n8n node): These flow control n8n node instances are crucial for compiling data streams from multiple parallel sources (EDR, Vulnerability, FIM) into a unified collection for downstream processing.
Risk Score Calculator (Function n8n node): The core processing element of this n8n workflow. It uses custom JavaScript to execute the complex, proprietary calculations required to generate a standardized endpoint risk score based on the merged security data.

• Google Sheets (n8n node): The final output action. It is configured to write the calculated risk scores (results from the Function node) into a specific Google Sheet, making the data accessible for reporting and analysis.
