Common Questions

These tools match IP addresses to company databases. When someone visits from a corporate network, the tool looks up which company owns that IP. Most identify 10-30% of B2B traffic. ISP and VPN traffic can't be matched.

Company-level identification using IP lookup is generally legal and GDPR compliant since no personal data is collected. Person-level identification varies by jurisdiction and typically requires more careful compliance consideration.

Typical match rates are 10-30% for B2B websites. Enterprise tools with larger databases may achieve higher rates. Traffic from home offices, VPNs, or mobile devices usually can't be identified.
