Vigil AI - Autonomous API threat detection with explainable AI decision

Hey Product Hunt! 👋 I'm Nikhilsai, a 1st year CS student from Chennai, India. I built Vigil AI because I was studying SOC/SIEM systems and realized — why do enterprise security tools cost $250+/GB/day and still give you zero explanation for why something was blocked? So I built the version I wished existed. Vigil AI runs 4 AI agents in a continuous loop — Monitor, Detect, Decide, Respond. What makes it different: → Every decision comes with a full reasoning trace → Per-API-key behavioral memory that learns over time → Confidence-weighted fusion (ambiguous signals abstain) → Integrates into FastAPI or Express in 3 lines → Free vs Splunk at $250-400/GB/day Built entirely in Python. Open source on GitHub. Would love feedback from the PH community — especially anyone who's dealt with API scraping or bot abuse on their own projects. Happy to answer anything! 🚀
