A virtual private network routes traffic through another network connection.

## Why it matters

Interpret a company match in light of how internet traffic was routed.

## Illustrative example

A remote employee may reach a website through an employer's VPN exit.

## What to check

A commercial VPN can hide the visitor's business behind the VPN provider.

## How Data SDK fits

Data SDK connects website visits with available company details worldwide, from startups to larger businesses. Coverage and fields vary. Start free trial opens an email request; terms are confirmed with the team. The full API is coming soon.

These are suggested workflows, not a list of built-in integrations. Use your own approved analytics, CRM, and research process where needed. Matches and fields vary. A company match does not identify a person or prove buying intent.
