Daily Tech & Security Briefing n8n with Ollama, Gmail & Discord

Get a daily, ranked tech & security briefing—automatically

This Daily Tech & Security Briefing n8n workflow pulls fresh security and tech updates from RSS feeds and CISA Known Exploited Vulnerabilities (KEV), uses local Ollama to classify and summarize the most important stories, then delivers a polished briefing to Gmail (SMTP) and Discord every morning.

What this workflow does

• Runs daily at 6:30 AM (or manually for testing) to start the briefing.
• Fetches recent items from your configured RSS/Atom feed list and downloads the CISA KEV JSON feed.
• Normalizes and filters titles, links, sources, and timestamps—keeping only items from the last 72 hours.
• Deduplicates using stable dedupe keys and checks against an n8n Data Table history; optionally performs semantic near-duplicate removal using Ollama embeddings and cosine similarity.
• Ranks and prioritizes stories by classifying each item via Ollama chat, applying boosts (keyword and freshness), and excluding topics you configure.
• Summarizes the top stories with Ollama: “What happened”, “Why it matters”, and “Personal relevance”.
• Sends the briefing as email HTML/text via SMTP and posts Discord-sized message chunks via webhook, then stores processed story keys/metadata in the Data Table.

Use cases

• Keep SaaS and engineering teams updated with security-relevant news without manual triage.
• For automation engineers: a hands-on example of RSS + KEV + LLM summarization inside n8n.
• For operators: get a short, prioritized daily readout with actionable context.
