Hey Product Hunt! 👋 I'm Alex, the founder of BlackIce. Most startups don't think about login security until an account takeover hits — and by then it's too late. I built BlackIce to fix that: a simple API that scores every login event for risk in real time, so you catch fraud before it becomes a support nightmare. What we detect today: Impossible travel (login from NYC, then Tokyo 10 min later) IP reputation & proxy/VPN abuse Suspicious device & behavior patterns Credential stuffing patterns Early access is completely free. I'm looking for founders in fintech or AI SaaS who want to stress-test it on real traffic. Drop your questions below — happy to go deep on how the detection works, the ML layer, or how to integrate it. 🧊
