Block Malicious IPs with Precision, Speed & Real-Time Data
Dealing with fraud, fake users, or suspicious logins? Fraudo.io gives you the tools to instantly block dangerous IP addresses using smart, constantly updating blocklists backed by a global threat network. Our system detects malicious behavior in real-time and reacts fast, helping you filter out fraud before it touches your platform.
Smarter IP Blacklists, Built on Live Data
Our IP blocklists are trusted by growing startups and enterprise platforms alike and for good reason. With over a decade of combined experience in cyber threat detection, we’ve designed our lists to deliver fewer false positives and faster detection than typical static blacklists.
Whether it’s fraud attempts, spam bots, click abuse, or credential stuffing, Fraudo.io flags the behavior quickly and blocks the source.
Real-Time IP Filtering for Smarter Defense
We don’t just collect IP data, we make it actionable. Our threat feeds pull from live fraud signals, honeypots, partner platforms, and abuse reports from all over the world. Every time a shady IP attempts a login, signup, or payment, we catch it, score it, and update our blocklists instantly.
What You Can Block:
- Fraudulent logins & signups
- Bot traffic & fake clicks
- Chargebacks & spam
- Residential proxy networks
- VPNs, TOR nodes, and open proxies
- Data scraping and DDoS attempts
- Known malware & botnet IPs
Bot IP Blacklists That Stay One Step Ahead
Bots evolve fast and so do we. Our bot IP blocklists update every minute with thousands of new records tied to automated scripts, virtual environments, and known Simulated devices
Fraudo.io tracks:
- IPs used in credential stuffing
- Fake installs and form spam
- Automated checkout or cart bots
- Suspicious virtual devices and VMs
- Traffic from residential proxy botnets
Using our IP blocklists, you can shut them down in seconds before they hurt your conversion rate, ad spend, or platform integrity.
Why Our IP Blocklists Work Better
Most blacklists are slow, inaccurate, or bloated with irrelevant data. We took a different approach. Here’s how:
- Fresh, not stale: Updates happen in real-time, not every few hours or
once a day.
- Verified abuse signals: We don’t guess. We use data from live
fraud events, partner sites, and our honeypot traps.
- Low false-positives: Accurate scoring helps keep legitimate users in,
and bad ones out.
- Scalable & reliable: Whether you serve 10,000 users or 10 million,
our lists scale with you.

Protect Against High-Risk IPs, Instantly
Our platform automatically flags and adds IPs that show signs of abuse, whether that’s fake signups, stolen cards, brute-force attacks, or suspicious geo patterns. We give you insight and control over who gets in.
And it doesn’t stop at traditional blacklists. We detect:
- VPNs, proxies, and anonymizers
- IPs tied to known malware or botnets
- Remote access tools like RDP or VMs
- Residential proxy abuse and tunneling
- Fast-spinning IPs used in bot attacks
Block Abusive Users Without Breaking the UX
Most fraud protection either blocks too little or too much. We built our IP filtering to strike the right balance. Our system adapts to new threats while keeping user experience intact. That means fewer chargebacks, cleaner data, and more revenue, without adding friction for real users.
Use our fraud scores and insights to:
- Flag suspicious logins or payment attempts
- Stop bot-driven traffic and fake leads
- Catch fake accounts during signup
- Add verification layers only when needed
What Is an IP Address Block List?
An IP block list is exactly what it sounds like, a list of IP addresses you don’t want anywhere near your platform. These might be known spammers, fraud rings, bots, VPN users, or hijacked devices. Use them to auto-block traffic or run checks before letting users through.
At Fraudo.io, our IP block list updates constantly to stay current with new fraud threats, so you’re not relying on yesterday’s data to protect today’s platform.
Why Use an IP Blacklist?
Simple. Because fraud’s expensive and preventable. Blocking risky IPs before the transaction happens saves you from:
- Chargebacks
- Fake signups
- Ad budget drain
- Spam content
- Account takeovers
- DDoS and scraping
With Fraudo.io, you can cut fraud before it even starts. And that means a safer, faster, cleaner experience for everyone else.
