Cipher Engine
Cipher is an engine we built in-house. More than 40 behavioural, device, and network checks feed a gradient-boosted fraud model, and a language model is called only when written answers need reading. Most of the work runs as fast, deterministic code on our own infrastructure, which is how a response costs a fraction of a cent to score.Use Cipher in your own code, no Surbee plan needed. Pay only for the responses you score, with prepaid credits that never expire.
