Daily Tech & Cyber Security Brief: RSS, GPT-4o & Gmail

This n8n workflow automates the creation of a daily briefing on tech and cybersecurity news. It starts with a Cron trigger to run daily, pulling headlines from reliable RSS sources like CISA, BleepingComputer, Krebs on Security, and others. Stories are merged, deduplicated by URL, filtered to the last 24 hours, and limited to a manageable number (e.g., 25) to ensure focus.

OpenAI GPT-4o then generates a concise, structured brief in JSON format, including sections, summaries, and 'Why it matters' insights, formatted as clean HTML. The result is emailed directly to your inbox via Gmail, providing a professional, ready-to-read newsletter without manual effort.

Benefits include time savings for busy professionals, reduced information overload through curation and AI summarization, and customizable sources for tailored relevance. Use cases span individual security awareness, team updates in IT/security departments, or executive digests in tech firms. Setup is beginner-friendly (10-15 mins) with mostly free costs beyond minimal OpenAI tokens.
