This n8n workflow automates the process of monitoring threat data, classifying critical alerts, and sending email notifications. It starts with a scheduled trigger that initiates the workflow, reads threat data from Google Sheets, classifies alerts as critical or non-critical, and finally sends email alerts when needed. The data is also stored or logged in Google Sheets for record-keeping. This setup is ideal for security teams or IT administrators who need real-time alerting and efficient management of threat information. The workflow can be customized to fit various security or monitoring scenarios, ensuring prompt reactions to potential threats.
