High-Accuracy VPN & Proxy Detection
Stop fraudsters, multi-accounting abusers, and geographic spoofers from bypassing your security controls using commercial VPNs, Tor nodes, or residential proxy swarms.

The Spectrum of Anonymized Traffic
Understanding the 4 principal vectors used to conceal digital identity:
Commercial VPNs
NordVPN, ExpressVPN, Surfshark, etc. Route through known datacenter IP blocks. Easily identified via ASN correlation.
Datacenter Proxies
SOCKS5/HTTP proxies hosted on AWS, OVH, or Linode servers. High speed, low cost, heavily used by simple web bots.
Residential Proxies
Traffic routed through genuine home ISP connections. The hardest to detect without behavioral telemetry and risk scoring.
Tor Exit Nodes
The Onion Router multi-hop network. Associated with extreme anonymization, dark web scraping, and automated exploit attempts.
Why Basic IP Lookups Fail Against Residential Proxies
Static IP databases categorize IPs based on static WHOIS registries. When a fraudster uses a residential proxy (rented bandwidth from real consumer broadband lines like Comcast, AT&T, or Jio), basic geolocation APIs report the IP as a genuine home user.
TrafficDam bypasses this limitation by combining connection velocity scoring, port fingerprinting, and ThreatGuard cross-network telemetry. When a residential IP initiates hundreds of concurrent sessions across multiple advertiser domains, its threat score rises immediately, filtering it before ad fraud or abuse can take place.
