1.1 Workflow description

Title
Automate security incident response with Google Sheets, email alerts and EDR isolation
Workflow name
Automate security incident response with Google Sheets, email alerts and EDR isolation

👤 Who it’s for SOC teams, incident responders, or solo defenders who need to automatically act on critical threats without manual triage.

Ideal for BlueOps users who’ve already classified alerts via GPT (Module 4) and want to auto-execute response steps like email alerts, logging, or EDR isolation.

⚙️ How it works / What it does Reads critical alerts from a classified incident log (e.g., Module 4 output)

Filters alerts by severity = Critical

Sends alert summary via email (custom HTML formatting)

Logs all details to a central incident response sheet

Optionally sends a request to your EDR/Isolation API (e.g. CrowdStrike or simulated API)

🛠️ How to set up Replace Placeholder API Key Swap in your secure ISOLATION_API_KEY from your EDR or proxy tool

Update Email Settings Insert your FROM_EMAIL and TO_EMAIL credentials in the Email node

Connect Sheets Authorize access to both your Classified Alerts sheet and Incident Log sheet

Schedule the Run Default trigger is weekly — change it to run hourly, on webhook, or via logic hook

📋 Requirements EDR or endpoint proxy API accepting POST requests

Open or pre-classified incident sheet (Module 4 required)

SMTP email provider or Gmail API access

Google Sheets or internal DB to log actions

🧩 How to customize the workflow Replace Google Sheets with Supabase or your internal SQL

Swap email alerts with ticketing system (e.g., Jira or Slack alerts)

Trigger downstream actions (e.g. auto-pause cloud assets)

Modify aggregation or isolation logic to your threat model

📦 This is a live-fire auto-responder workflow. Make sure to test with dummy data before enabling full EDR triggers. All sensitive variables are clearly marked with placeholders.

4. Reproducing the Workflow from Scratch

  1. 1. Download the workflow JSON

    Use the JSON export at /data/workflows/6413/6413.json as the source template for this automation.

  2. 2. Import the template into n8n

    Open n8n, import the downloaded JSON, and review each node before activating the workflow.

  3. 3. Configure credentials and variables

    Replace placeholder credentials, API keys, webhook URLs, account IDs, and environment-specific values with your own settings.

  4. 4. Test with sample data

    Run the workflow manually or in a staging workspace, inspect node output, and confirm downstream systems receive the expected data.

  5. 5. Activate and monitor

    Enable the workflow only after testing, then monitor executions, errors, and rate limits during the first production runs.

5. General Notes & Resources

Review imported nodes carefully before activation. This catalog entry is intended to help you inspect the workflow structure, understand required services, and find related templates faster.

Node names, credentials, schedules, webhook paths, and external service limits may need adjustment for your workspace.
