Why LIVE Detection?

Static Proxy and VPN IP blocklists are outdated the moment they are published. Our engine classifies live traffic in real time to detect ALL the proxies and VPNs.

Offline Proxy and VPN datasets are always a step behind. Bot Operators and Threat Actors can launch new infrastructure faster than any static feed can be updated.

Static feeds miss exits

Even premium lists are incomplete — new proxy clusters and residential pools come online every hour outside existing coverage.

Bots pivot to fresh IPs

Threat Actors rotate to undetected IP ranges or high reputation IPs (mobile, residential) that can't appear on yesterday's blocklist, bypassing any static enforcement.

Real-time Signals

Live telemetry such as TCP/IP Fingerprints, Latency Data and Network Flows are used to detect Proxy and VPN connections with 98% accuracy.

The only way to catch every proxy and VPN connection is to watch the traffic as it happens.
