Proxy VPN TOR detection is an API service that provides you with a real number between 0 and 1 of how likely it is that the IP address is a proxy, a VPN server or a TOR exit node. This is calculated through machine learning & probability theory techniques using dynamic checks with large datasets. The data is constantly updated and old records automatically expire. This makes our service efficient, fast and simple to use.

Proxies are used by internet users who want to hide their identity online and avoid getting blocked or slowed down when accessing websites and services. However, some proxies are also used by fraudsters to spoof their location or for other fraudulent activities such as spamming, brute-force attacks and other malicious actions.

What Is Proxy Detection and Why It Matters for Online Security

VPN is similar to a proxy but it encrypts traffic between the client and the remote server making it harder for snoopers to intercept user data. One easy way to detect VPN connections is by comparing the timezone of the IP address with the browser timezone, as well as checking for known ports used for proxies such as port 22 (SSH), 3128 and 8081.

TOR or The Onion Router is a software layer that bounces your internet traffic around different relay nodes to mask the origin of your request. Like a VPN, it is also a good choice for users that require high levels of privacy such as law enforcement agencies, media companies and financial services providers.
