Stop Hidden Users, Fake Accounts, Chargebacks, and Suspicious Logins
Online fraud rarely looks obvious at first. Fake users hide behind VPNs, rotating proxies, and anonymous networks to slip past basic security checks. They create duplicate accounts, abuse promotions, drain ad budgets, trigger chargebacks, and scrape data that was never meant to be public.
Frauddefense helps you detect and stop these threats in real time without guesswork.
Our IP and proxy detection tools expose what’s really happening behind every login, signup, click, and transaction.
Proxies and VPNs Give Fraudsters Cover We Take It Away
Fraudsters don’t attack openly. They mask their identity using VPNs, TOR, mobile proxies, residential IPs, and data center networks. This makes them appear like normal users while they commit payment fraud, ad fraud, account abuse, and content theft.
Frauddefense looks beyond surface-level IP checks. Whether traffic comes from a VPN, proxy network, or anonymized exit node, our IP reputation system detects risky behavior early so fraud never reaches your bottom line.
Advanced Proxy Detection with frauddefense
Frauddefense delivers powerful proxy detection built for modern fraud challenges. Our system helps businesses instantly identify users hiding behind VPNs, proxies, TOR networks, botnets, and other anonymized connections—before they can cause damage. Whether you’re reviewing traffic in real time or analyzing past data, frauddefense.io gives you clear visibility into risky connections.
You can access the frauddefense Proxy Detection Service in multiple ways to match your workflow. Run live checks using our REST API, review traffic directly from the user dashboard, or upload CSV files to analyze leads, clicks, or historical user data in bulk. Each lookup triggers a real-time evaluation designed to reduce fraud at the source.
For every request, frauddefense analyzes the IP address along with several technical and behavioral signals. The system looks for signs of spoofed locations, tunneled connections, rotating proxies, residential exit nodes, and automated behavior. Instead of relying on simple allow-or-block logic, frauddefence assigns a clear IP reputation and risk score that shows how likely the connection is to be abusive.
Our detection engine covers all major anonymity methods, including VPNs, residential proxies, mobile proxies, data center IPs, and TOR networks. More than 25 intelligence signals are combined to create a detailed risk profile for each click, login, signup, or transaction. This allows you to make smarter decisions without slowing down real users.
Threat intelligence is continuously refreshed using global traffic patterns and live abuse reporting. New malicious IPs are added quickly, while outdated or inactive proxy addresses are removed regularly. This balance helps frauddefense maintain high accuracy and significantly reduce false positives, ensuring legitimate users are not blocked unnecessarily.
