Many internet users facing concerns regarding their privacy. These concerns are valid, a lot of companies and agencies out there that handle personal data are not completely honest. This is why a lot of people use proxies and VPNs to hide their original identities.

What is a VPN Detection API?

A VPN detection API is a tool or anonymous detection algorithm that can help you discover if the traffic on your network is using proxies or VPNs or even Tor connections. In other words, it tells the owner of the network that a masked IP address is on his/her network. But then, VPN detection API calls can help prevent unwanted traffic from entering your network.

Advantages of a VPN Detection API?

a) Fraud Prevention/Reduction

Financial institutions, including banks, can verify if a client is who he or she actually claims to be by simply checking his or her IP address with the help of a VPN detection API. Transaction processing systems as well as portals for payments can be able to detect fraudsters who may be using stolen identities or other credentials of customers. Sudden use or a change of proxies can be a red flag for fraud.

b) Increased filtering of traffic

A configured VPN anomaly detection algorithm can automatically identify and restrict proxy users from getting into your network, this will reduce the chances of a network breach. This aids organizations and companies to keep out potentially dangerous users that may have seemed to bypass your network's built-in security through IP spoofing.

c) Strengthens digital rights management (DRM)strategies

Streaming service providers can restrict unauthorized subscribers or viewers from having access to the content using the help of a VPN detection API. It is useful for geo-restricted content like(movies, tutorials, shows, etc...).

d) Significantly reduces Fake account signups & Free trial abuse

When it comes to fake account signups, a proper VPN detection API integration can restrict signups from subscribers with masked IP addresses. Also, Tor, proxies, or VPN users with marked IPs can not avail free offers online.

curl "https://vpnapi.io/api/{ip_address}?key={api_key}"

The IPIFY VPN Detection API

Another anomaly detection algorithm is the IPIFY VPN API. It is also an easy tool to use. It works similarly to the earlier API detection system.

To get access to this anomaly detection algorithm. IPIFY's VPN detection API can be adopted into payment systems and portals, alert systems of a company or network. It will help to mitigate threats that can result in harm to their business or network respectively.
