A real-time proxy detection API for securing modern web platforms.

Proxies are used for many legitimate purposes, including privacy, traffic routing, caching, and accessing geo-restricted content. However, fraudsters rely on them to mask their activity and evade security measures. Whether they are using fake identities, bot attacks, or slow-rotating residential proxies to bypass velocity controls, the ability to detect these threats is a key ingredient for security teams.

Fraudlogix’s real-time proxy detection API identifies connections that are masked by proxies, ad-blockers, and other tools to hide user location and activity. The system analyzes carrier-grade NAT (CGNAT) patterns, distinguishes between mobile network gateways and residential broadband, and flags rotating IP addresses commonly found in proxy pools. Adding this data point to existing risk scores and blocking rules can help protect against account takeovers, click fraud, bot attacks, and other forms of identity theft.

Proxy Verification API: Validate IP Authenticity and Prevent Abuse

Residential Proxy Detection adds an additional layer to IPinfo’s existing Privacy Detection data, which identifies VPNs, relays, hosting providers, and Tor. It also tags IPs exiting via mobile carrier gateways, identifying these as a potential source of malicious activity. Adding this to login flows, WAF integrations, and threat detection systems can improve accuracy, reduce false positive noise, and prioritize alerts.

Ad tech companies use this data to refine their targeting strategies, ensuring that ads are displayed only to genuine users. Travel companies use it to prevent fraudulent signups and synthetic identities. Streaming services use it to catch attempts to circumvent region-locked content restrictions, and SaaS and ecommerce platforms rely on it to detect regional price arbitrage and scalper bots.
