Proxy & VPN Detection

Tell an ordinary customer apart from someone hiding behind a Tor exit, a commercial VPN or a residential proxy.

What you get

usage_class	Our taxonomy: anonymiser_tor, anonymiser_vpn, anonymiser_proxy, consumer, business, datacenter, mobile, compromised_host, automation
fraud_indicators.anonymising	True when traffic is being deliberately obscured
fraud_indicators.residential_proxy_shape	Residential address behaving like a proxy — the hardest case to catch
fraud_indicators.high_device_density	Unusual number of devices behind one address
signals[]	Which anonymity signals fired, and how much each moved the score

Block Tor outright, challenge a VPN, let a home connection through untouched.

One person opening fifty free accounts is usually one proxy pool.

Detect the VPNs used to jump regional restrictions.

We publish our own classification and the signals behind it, not our supplier’s raw detection flags.
