What Is a VPN, Really?
A Virtual Private Network (VPN) creates a secure, encrypted connection between your device and the wider internet. It keeps your data hidden from ISPs, governments, and anyone else watching including the websites you visit. It’s great for privacy, but also perfect for hiding behind fake locations or IPs.
Why Do People Use VPNs?
VPNs aren’t always bad. Businesses rely on them to give remote workers secure access to private systems. And in places where the internet is censored, people use VPNs to access basic services like Google or YouTube.
But that same privacy cloak can be used to commit fraud like fake signups, ad fraud, carding, phishing and many more.
Are VPN Users Always a Risk?
Not always. But when fraudsters want to stay hidden, VPNs are usually their first stop. That’s why our detection tools don’t just say “Yes” or “No.” We give you context like whether the IP comes from a known VPN server, how risky its history looks, and how often it’s been used in shady behavior.
How Does VPN Detection Work?
It’s simple. You send us an IP. We check it against our constantly updated threat network and detection engine. We’ll tell you if it’s likely to be a VPN, proxy, or Tor exit node and how risky the connection is based on behavior patterns, hosting provider checks, known abuse reports, and connection anonymity. You can do it through our dashboard or plug directly into our VPN Detection API.
