Network Detection

VPN Detection

Detect active VPN connections in real-time

What it detects

Identifies visitors using commercial VPN services, corporate VPNs, and proxy networks. Combines ASN classification, IP reputation databases, and network behavior analysis to detect even advanced VPN configurations that mask their traffic patterns.

How it works

Cross-references the visitor's IP against known VPN provider ASN ranges and IP databases. Analyzes RTT timing patterns for anomalies that indicate traffic routing through intermediary servers. Checks for network-level signatures common to VPN protocols including WireGuard, OpenVPN, and IPSec tunnels.
