Crypto exchanges get hit by account takeover, bonus and multi-accounting abuse, and bot-driven signups, and they share one tell: the same device behind fresh emails, rotated IPs, and even clean KYC. So the tools worth shortlisting identify the device itself, in the browser, rather than trusting an IP or a verified identity. cside reads 250+ per-session signals to catch VMs, emulators, headless browsers, and residential-proxy use, and links accounts back to a shared device in real time. It runs from one first-party script and sits alongside your KYC and existing fraud stack, not in place of it.
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.
