Fraud prevention should be simple to build

We built Zeno to protect our own logins, sign ups and bonuses, and made it a service any developer can run in front of theirs.

Signals, not verdicts

We tell you what a device looks like and why. You decide what happens, in your own code.

Only what identification needs, kept as long as you say, erased in one call.

Plain REST, typed clients, docs you can read in an afternoon and no sales call to start.

A shared visitor ID is a lead, not proof. Our docs say what we don't do as plainly as what we do.

100+ device signals per identification

22 smart signals on every event
