Whether you’re a fraud analyst, security engineer, or product builder, understanding the risks of proxy and VPN usage is key to protecting your users. Incorporating our proxy detection API into your application helps you detect users connecting to your services through proxies and tunneling tools. This can be a red flag for fraudulent activity, such as account takeovers and other scams. It can also signal that an end user is attempting to bypass geographic restrictions or evade content access.

With our real-time proxy detection API integration guide, you can identify when an IP address is associated with a bogon or known VPN, Tor, or other proxy service. This can help trigger additional verification steps in your onboarding, authentication, or risk assessment flows and flag high-risk transactions. This is particularly useful for e-commerce and fintech applications that need to protect sensitive payment data, as well as SaaS platforms that need to prevent mass account creation through automated bots.

IP Reputation Analysis API: Score and Monitor Risk in Real-Time

The API offers dynamic checks that analyze the behavior of an IP address against a database of known malicious and spoofing patterns. If the check returns a value of 1, this means that the IP has been manually banned or seen on a public proxy website. This value is exclusive and does not take into account any other behavioral characteristics the IP might exhibit. To get a more comprehensive risk score, developers can combine this API with other data channels, such as geolocation and threat intelligence, to assess the probability that an IP is involved in malicious activities.
