Device intelligence and behaviour biometrics for fraud and compliance

The short version
- Each has a real cost: Polco interface has a formal, academic tone compared to modern civic engagement platforms; Sardine signal quality depends on the SDK being embedded in your own web and mobile clients, so fraud improvements become dependent on your app release cycle and any coverage gap is a blind spot.
- They diverge on capability: Polco covers Scientific Surveys, Sardine covers Device intelligence.
- Prices and features above were last checked on 1 September 2026.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Polco
- Interface has a formal, academic tone compared to modern civic engagement platforms
- Emphasizes surveys and benchmarking over open discussion forums and idea boards
- Pricing is custom quote-based without transparent pricing on the website
Sardine
- Signal quality depends on the SDK being embedded in your own web and mobile clients, so fraud improvements become dependent on your app release cycle and any coverage gap is a blind spot.
- Behavioural and device telemetry collection needs a documented lawful basis under GDPR, and EU privacy reviews frequently delay rollouts that were scoped as engineering work.
- Pricing is per session or per active user, so a consumer product with many low value sessions pays in proportion to traffic rather than to fraud exposure.
- As a younger private company it lacks the enforcement-tested audit history that a bank examiner expects, which makes it a harder sell inside a regulated bank than inside a fintech.
- It is strongest on session-time signals and weaker as a system of record for long horizon AML typologies, so larger institutions end up running it alongside a traditional monitoring platform rather than instead of one.
