BlackIce is a login risk engine for fintech and AI SaaS. Detect account takeovers, impossible travel, and credential abuse in real time — before they cost you users and trust. Drop in our API, get risk scores instantly. Free early access, no credit card.
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. 🧊
