It comes down to scope. Fingerprint is a focused device-identity API: you call it, you get a visitor ID. cside gives you the device ID and the fraud context around it, behavioural bot and AI-agent detection, VPN and residential-proxy detection, and Compelling Evidence 3.0 chargeback data, from a single first-party script that also runs script monitoring and PCI DSS 4.0.1 automation validated by VikingCloud. If all you need is an identifier, either works; if you want fraud, bot, and browser-security signal from one integration, that is cside. The full side-by-side is on the Fingerprint vs cside page.
How does cside handle browser-based fraud detection for fintech companies?
cside's Device Intelligence captures a baseline of 250+ browser, device, and network signals per session to build a privacy-preserving device identifier, with no cookies.
What is device intelligence and how does it prevent fraud?
Device intelligence analyses the browser, device, and network signals of every visitor to recognise the device behind a session and judge how risky it is.
Why do IP-based fraud rules fail against VPNs and proxies?
An IP is trivial to rotate. cside looks past the IP at the device itself, detecting VPN and residential-proxy use while still recognising the device.
What signals make a device fingerprint stable across sessions?
Stability comes from combining many independent, slow-to-change signals. cside weights 250+ attributes so the identifier survives cookie clearing and incognito.
