Auto Cve & Ioc Feed Ingestor With Openai Risk Triage & Email Alerts 6356 – n8n Workflows – Free Template

What This Workflow Does

The CYBERPULSEBlueOps Module 1 workflow automates the ingestion and processing of cybersecurity threat intelligence feeds. It retrieves CVE (Common Vulnerabilities and Exposures) and IOC (Indicators of Compromise) data on a scheduled basis, enriches this information using AI-powered triage mechanisms, and intelligently routes security alerts to appropriate response actions including notifications, system isolation, or continuous monitoring.

How It Works

This workflow operates through a series of coordinated automated steps:

• Scheduled Trigger: Initiates the workflow on a daily schedule to ensure consistent threat feed ingestion
• HTTP Request: Fetches the latest CVE and IOC threat intelligence data from configured security feeds
• Merge & Code Processing: Combines multiple data sources and applies custom logic for data normalization and enrichment
• AI-Based Triage: Evaluates threat severity and risk levels using intelligent decision logic
• Conditional Routing: Directs threats through the appropriate response channel based on severity assessment
• Multi-Channel Notifications: Sends alerts via email and logs findings to Google Sheets for compliance tracking
• Automated Response: Triggers isolation protocols or monitoring escalations for critical threats

Use Cases

• Enterprise Vulnerability Management: Automatically ingest daily CVE feeds and alert security teams to vulnerabilities affecting your infrastructure
• Threat Intelligence Monitoring: Continuously monitor IOC feeds and correlate indicators against your network logs to detect compromised assets
• Compliance & Audit Logging: Maintain detailed records of all ingested threats and response actions in Google Sheets for regulatory compliance frameworks
• Incident Response Automation: Automatically route high-severity threats to incident response teams while quarantining or isolating affected systems
• Security Operations Center (SOC) Enhancement: Reduce manual alert triage workload by automating threat feed processing and intelligent risk prioritization

Nodes Used

• Schedule Trigger: Establishes the daily automation schedule
• HTTP Request: Retrieves threat intelligence data from external sources
• Merge: Combines multiple data sources into unified payloads
• Code: Executes custom logic for data enrichment and transformation
• If: Implements conditional branching based on threat assessment criteria
• Email Send: Delivers real-time security alerts to designated recipients
• Google Sheets: Logs and archives threat intelligence for compliance and historical analysis
• Switch: Routes threats to different actions based on severity classification
• Split Out: Processes individual threat records through parallel execution paths
• Sticky Note: Documents workflow logic and configuration notes for team reference

Prerequisites

• Access to threat intelligence feeds (CVE databases, IOC sources, or commercial threat feeds)
• HTTP API endpoints configured for threat data retrieval
• Email service configured for alert notifications
• Google Sheets API credentials and target spreadsheet for logging
• n8n instance with HTTP Request, Email, and Google Sheets integration support
• Understanding of threat severity classification and response procedures
• Compliance framework requirements documented (SOC2, NIST, ISO 27001, etc.)

Difficulty Level

Advanced – This workflow requires knowledge of cybersecurity threat intelligence, API integration, conditional logic flows, and compliance frameworks. It is best suited for security operations teams with technical expertise in automation and threat management.
