How Trueguard detects fake accounts
Fraudsters use VPNs, proxies, and disposable emails to look like new users. Trueguard correlates device, network, and email signals to catch the person behind the screen.
Device fingerprinting
Persistent IDs from browser, hardware, and JA4/TLS network fingerprints catch the same device opening multiple accounts, even after a cookie clear or VPN switch.
