In this video, I’m walking you through a complete, production-ready setup of a mini SOAR (Security Orchestration, Automation, and Response) platform built from scratch using n8n.

If you've ever wondered how modern Security Operations Centers (SOCs) handle thousands of alerts without burning out, the answer is automation. I’ve moved this entire system into a VirtualBox environment running Ubuntu and Docker to show you exactly how to bridge the gap between manual investigation and instant response.

What this system does:
When a security alert triggers (like a potential hacking attempt), this workflow automatically takes over. It gathers threat intelligence from VirusTotal and AbuseIPDB, calculates a real-time risk score, and decides whether to block the threat—all in about 4 seconds. What usually takes a human analyst 15 minutes, we’ve automated down to a few heartbeats.

In this technical walkthrough, we cover:

Infrastructure: Setting up the environment using Ubuntu, Docker, and VirtualBox.

The n8n Workflow: A node-by-node breakdown of the automation logic.

API Integration: How to connect professional security tools like VirusTotal and AbuseIPDB via webhooks.

Logic & Decision Making: How the "IF" nodes and risk scoring functions work to prevent false positives.

Automation in Action: Sending a test alert via curl and watching the system investigate and block in real-time.

Whether you're a cybersecurity student, an aspiring SOC analyst, or a home-lab enthusiast, this project will give you a practical look at the future of cyber defense.
