The key to protecting against fraud, account takeovers, and other advanced cyber threats is detecting the presence of proxy and VPN connections.

Residential Proxies

Fraudsters and other criminals hide their true identities by using proxies or VPNs. By detecting these connections, our API can help prevent advanced fraud such as chargebacks, fake accounts, and other account takeover attacks.

For example, e-commerce platforms can detect fraud and flag suspicious transactions based on the presence of a proxy or VPN to ensure that payments are legitimate. In addition, banking systems can flag logins and transactions coming from known proxies or VPNs so that fraudsters are not able to access their accounts.

In the world of ad tech, detecting proxies and VPNs allows ad networks to refine their targeting and avoid click fraud by ensuring that ads are only displayed to users who can actually see them. The API also helps game makers enforce geographic restrictions and ensure that users are not using proxies or VPNs to bypass region-locked content.
