Stop fraud before
it reaches you.
Real-time request analysis in under 3 milliseconds. One API call, instant verdict, zero friction for real users. Drop it in today, stop the bleeding tomorrow.
From one <script> tag to catching fraud in five minutes.
No agents, no sidecars, no heavy review tooling. Three steps, and you're on the critical path.
Drop in the SDK
A single <script> tag. Signals are collected and encrypted in-browser before they move an inch.
const fp = new SignalGate.Fingerprint({ key: "YOUR_TENANT_KEY" })
await fp.start()
Call /v0/check
Send the encrypted payload on every protected action — login, signup, payment, OTP send. Verdict back in under 3ms.
Fraud stops, quietly
SignalGate learns from your traffic and acts on the patterns it finds. Real users never see a captcha. Fraudsters see a door.
Same solution. Different threats.
SMS pumping drains your budget silently
Fraudsters hit your OTP endpoint in waves. Your carrier charges per SMS. The codes are never entered — because there's no real user on the other end.
- Pumping rings coordinate across thousands of rotating IPs
- Rate limits don't help — attacks stay just under every threshold
- You can't tell a real failed verification from a pumped one
Serious fraud detection, without the friction tax.
