IP Address Blacklist

Block Malicious IPs with Precision, Speed, and Real-Time Intelligence

Fraud, fake accounts, and suspicious login attempts can damage your platform faster than almost any other threat. Fraudo.io is built to stop that damage before it starts.

Our intelligent IP blocking system allows you to identify and block dangerous IP addresses instantly using continuously updated blocklists powered by a global threat intelligence network. Every connection is analyzed in real time, allowing you to react immediately and prevent malicious activity from ever reaching your users, data, or infrastructure.

Smarter IP Blacklists Built on Live Threat Data

Traditional IP blacklists rely on static data that quickly becomes outdated. Fraudo.io takes a different approach. Our IP blocklists are created and maintained using live behavioral signals, real-world fraud activity, and continuous monitoring across thousands of sources.

With years of combined experience in fraud prevention and threat detection, our team has engineered blocklists that are more accurate, faster to respond, and far less likely to block legitimate users.

Whether you are dealing with automated fraud attempts, bot-driven abuse, click manipulation, or credential stuffing attacks, Fraudo.io detects suspicious behavior early and blocks the source before it escalates.

Real-Time IP Filtering Designed for Modern Threats

Fraudo.io ingests live signals from honeypots, partner networks, behavioral analysis systems, and global abuse reports. Each time an IP attempts a login, signup, payment, or API request, it is evaluated in real time.

If the behavior matches known fraud patterns, the IP is scored, flagged, and added to our blocklists instantly.

This real-time approach ensures that new threats are stopped as they emerge, not hours or days later when the damage is already done.

What You Can Block with Fraudo.io

• Fraudulent logins and fake account registrations
• Automated bot traffic and fake clicks
• Spam submissions and chargeback-related abuse
• Residential proxy networks and tunneling services
• VPN traffic, Tor exit nodes, and open proxies
• Data scraping, brute-force attacks, and DDoS attempts
• IPs linked to malware, botnets, and coordinated attacks

Each block decision is backed by live data and behavioral context, not guesswork.

Bot IP Blocklists That Evolve as Fast as Bots Do

Bots constantly adapt, rotate IPs, and mimic human behavior. Fraudo.io stays ahead by updating bot-related IP blocklists every minute with thousands of new records.

Our system tracks IPs involved in credential stuffing, automated checkouts, fake installs, form spam, and abuse driven by residential proxy botnets. This allows you to shut down bot traffic in seconds.

Why Fraudo.io IP Blocklists Perform Better

Most IP blacklists fail because they are slow, inaccurate, or overloaded with irrelevant data. Fraudo.io was built to solve those problems.

Our blocklists update in real time rather than on fixed schedules. Every IP is backed by verified abuse signals, and advanced risk scoring minimizes false positives while keeping legitimate users unaffected.

Flexible Ways to Use Our IP Intelligence

Fraudo.io fits seamlessly into your existing technology stack. Integrate via real-time API, download flat-file blocklists, or use pre-built plugins for popular frameworks.

For advanced use cases, our API allows custom automation and decision logic tailored to your business rules.

Instant Protection Against High-Risk IPs

Our platform automatically detects IPs linked to fake signups, stolen payment activity, brute-force attacks, suspicious geographic behavior, VPNs, proxies, anonymizers, malware-linked IPs, and fast-rotating bot infrastructure.

You gain full visibility into why an IP is risky and complete control over how your system responds.

Block Abuse Without Hurting Real Users

Overly aggressive fraud protection can be just as damaging as no protection. Fraudo.io minimizes friction for genuine users while aggressively stopping malicious traffic.

Use fraud scores to flag suspicious logins, block bot traffic, detect fake accounts during signup, and apply additional verification only when needed.

What Is an IP Block List?

An IP block list is a collection of IP addresses known or suspected to be harmful. These may be linked to spam, fraud rings, bots, anonymizers, or compromised devices.

Fraudo.io maintains a continuously updated IP block list, ensuring protection based on current threat data.

Why Using an IP Blacklist Matters

Blocking risky IPs early helps prevent chargebacks, fake accounts, wasted ad spend, spam, account takeovers, scraping, and denial-of-service attacks.
