Antifraud built by engineers, for engineers.
The fraud-detection market is owned by black-box vendors that sell six-figure annual contracts to enterprises with full-time security teams to operate them. The product is opaque, the integration is slow, and the logic sits somewhere the customer can’t touch. SignalGate is the opposite of that.
We’re building antifraud that an engineer can start logging with in about ten minutes and tune to their own risk. You configure the workflows that decide what is checked, how strict it is and whether it blocks. And the device signals are encrypted in the browser before they ever leave the device.
You shouldn’t need a procurement cycle to stop fraud on your signup form.
What that actually means
Three product commitments that follow from the thesis. They shape every decision we make about what to ship.
No black box
You configure the workflows — what is checked, how strict it is and whether it blocks — and SignalGate learns from your own traffic which visitors finish what they start, re-learning on a schedule from every few minutes to hourly. It’s built for your traffic, not a generic one-size model.
You ship the integration today
A self-serve dashboard, an SDK that drops into any modern JavaScript site, and a single HTTP endpoint for the verdict. No sales call required. No professional services line item. Sign up, drop in your public key, ship.
Encrypted from the browser
Device signals are encrypted in the browser, before they leave the page. Only our API can decrypt them.
What we believe in
The principles that guide how we build, how we work, and how we serve our customers.
Tuned to your traffic
SignalGate adapts to what your own users actually do — detection is shaped by your traffic, not a generic one-size model.
Built for engineers
Self-serve dashboard, real docs, structured configs, an HTTP endpoint. We assume you'd rather read code than book a call.
Ship fast, fix in public
We'd rather get a small, correct primitive into your hands today than spend a year polishing the marketing site. The roadmap moves with what customers actually run into.
Where we are right now
SignalGate is in open beta. The dashboard, the API, the SDKs and the encryption are all live; the polish and the long tail of integrations are being built in the open.
If your team has a fraud problem you’d like us to look at, please get in touch. If you just want to kick the tyres, sign up — the API key is free to start with.
Stop fraud before it reaches your backend.
Free until December 31, 2026. About ten minutes to start logging. No demo required.
