VPN Detection
Detect VPN in Seconds
Check any IP for VPN usage with a single call, and get a confidence score with every verdict.
Key Features
Keeps up with new servers
We track hundreds of VPN providers and add fresh exit nodes within hours, so new servers don't slip past.
Answers in milliseconds
A lookup returns fast enough to run inline on a login or checkout without holding up the page.
A verdict you can tune
Every result carries a confidence score, so you choose where to draw the line between allow and block.
What Is VPN Detection?
A VPN (Virtual Private Network) creates an encrypted connection from a device to a remote server, masking the user's real IP address and location. VPN detection looks at an IP address and works out whether it belongs to one of these services rather than an ordinary home or business connection. Because no single clue is conclusive, reliable detection weighs several network signals together before it calls a connection masked.
How VPN Detection Works
No single clue settles it. The engine weighs several signals together to keep false positives low.
IP Reputation
Looks at past spam reports, abuse velocity, and odd behavior tied to the address.
Network Ownership
Picks out hosting environments and organizations that tend to run VPN services.
Hosting & ASN Data
Reads the Autonomous System Number and the network behind each IP.
Known VPN Servers
Checks the address against lists of VPN servers and exit nodes that we refresh constantly.
Traffic Patterns
Watches for the connection and flow patterns that tunneled VPN traffic tends to leave.
External Signal Feeds
Pulls in feeds from across the web so newer VPNs surface faster.
Why Businesses Detect VPNs
Fraud Prevention
Catch signups and transactions that hide their real identity and location.
Account Security
Notice connection changes that can point to a compromised or hijacked account.
Trial & Promo Abuse
Stop people from resetting free trials and promo limits with fresh masked IPs.
Risk Scoring
Feed the VPN result in as one signal among many across logins, payments, and signups.
