Fraudo.io – Real Proxy & VPN Detection That Actually Works

Stop hidden users, fake accounts, chargebacks, and suspicious logins.

Fraudo.io helps you catch them all in real-time, with zero guesswork.

Proxies and VPNs Give Fraudsters Cover — We Take It Away

Fraudsters love to hide. They use proxies, VPNs, Tor, and residential IPs to fake who they are and where they’re from. That’s how they sneak into your systems, use stolen cards, make duplicate accounts, click on ads with bots, and scrape content they shouldn’t even see.

Whether someone’s hiding behind a VPN, a mobile proxy, or a data center IP, Fraudo.io sees right through it. Our IP reputation system flags shady behavior early, so you don’t pay the price later.

What Makes Fraudo.io Different?

It’s Fast and Fresh

We don’t rely on stale IP blacklists from last week. Our threat data updates in real-time. That means you’re blocking real threats, not regular people using public Wi-Fi.

It’s Smart

Every IP check goes beyond the surface. We pull over 25 data points, from user agent to connection type and roll it into an actionable fraud score. So you know who to trust and who to block.

You’re in Control

Tighten the rules, loosen them, or set custom thresholds. With flexible scoring settings, you can tune Fraudo.io to match your risk level, not someone else’s.

It’s Easy to Plug In

Our Proxy Detection API is simple to integrate. Use it via REST API, upload a CSV, or hop into the dashboard. Whether you’re an engineer or a non-technical founder, Getting started is simple.

How Proxy Detection Works at Fraudo.io

It’s simple. Here’s what happens every time a user lands on your site:

  1. We scan the IP address in real-time.

  2. We look for red flags: is it a known VPN? Is the IP tied to a data center? Are they rotating proxies or residential exit nodes?

  3. You get a detailed risk breakdown and IP reputation score

We’re not just flagging IPs. We’re scoring behavior. And that gives you more than just “yes” or “no” - it gives you context.

Use Fraudo.io to:

Catch Fake Signups & Duplicate Accounts

Tired of users signing up over and over with multiple emails and temporary numbers? Chances are, they’re hiding behind proxies. Fraudo.io spots them fast, so you can block them before it hits your system.

Stop Click Fraud

Click fraud isn’t always easy to spot - bots and cloaked users eat up your ad budget while looking legit. Fraudo.io gives you real-time VPN and proxy detection, so you can shut down fake traffic before it can do any damage or drains your funds.

Prevent Payment Fraud & Chargebacks

Fraudulent payments often come from anonymized IPs. Fraudo.io’s smart fraud scoring helps you spot risky transactions before they go through, saving you from chargebacks and refund headaches.

Block Account Takeovers

When someone logs in from a residential VPN or high-risk proxy, it may not be your real user. We help you detect these sessions right away so you can take action before damage is done.

Enforce Geo Restrictions

Need to limit access to certain countries or regions? We make that easy. Fraudo.io’s tools handle geo enforcement which is hard to bypass.

Shut Down Bots and Crawlers

We identify botnets, scraper farms, and proxy-connected crawlers the moment they hit your site. Say goodbye to unauthorized scraping.

Clean Up Lead Generation

Are your leads actually people? Score their IPs, check for proxy usage, and validate their data before you waste money nurturing fakes.
