Whether you’re preventing account takeovers, stopping chargebacks, or ensuring compliance, we provide granular risk scoring without compromising privacy (GDPR and CCPA compliant). Skip outdated blacklists and manual reviews—leverage machine learning models trained on 25+ years of behavioral data for unparalleled accuracy.

What Is Proxy Detection and Why Is It Essential?

Proxy detection identifies IP addresses routing through anonymizers like VPNs, proxies, data centers, or residential proxies, flagging potential fraud risks. In an era of sophisticated attacks—where 40% of online traffic is bot-driven (per industry reports)—accurate detection prevents:

• Fraudulent Activities: Bonus abuse, fake accounts, and payment fraud costing businesses $50B+ annually.
• Security Threats: Credential stuffing, DDoS attacks, and ad fraud via hidden IPs.
• Compliance Issues: KYC/AML violations in fintech or geo-restrictions in streaming/media.
• User Experience Degradation: Bots skewing analytics, inflating metrics, or scraping content.

IPQS goes beyond basic geo-IP lookups. Our API cross-references 100+ signals, including connection anomalies, abuse velocity, and device fingerprints, delivering a comprehensive risk score (0-100). Low scores indicate clean traffic; high scores signal proxies or abusers. Supports IPv4/IPv6, with abuse history dating back years—ideal for real-time decisions in login flows, checkout processes, or API gateways.

Key Insight: Unlike legacy solutions with 70-80% accuracy, IPQS boasts 95%+ detection rates for residential proxies and VPNs, reducing false positives by 90% through proprietary ML algorithms.

Core Features of the IPQS Proxy Detection API

Our API is engineered for scalability, security, and ease-of-use, with robust documentation and SDKs in 10+ languages (Python, PHP, Node.js, etc.). Here’s what sets us apart:

1. Real-Time IP Analysis

• Detects proxies, VPNs, Tor exits, hosting providers, and public hotspots.
• Flags crawled IPs, bots, and malicious user agents.
• Response Time: <50ms globally via edge cached nodes.

2. Advanced Risk Scoring

• Fraud Score: Overall risk (0-100) based on proxy type, recent abuse, and velocity.
• Proxy/VPN/Tor Indicators: Boolean flags with confidence levels.
• Connection Type: Residential, mobile, data center, or education/government.
• We distinguish between residential, mobile and datacenter proxy connections, enabling policies that block hosting-provider traffic while allowing legitimate carrier/ISP usage.

3. Enrichment Data

• Geolocation: Country, city, ZIP, latitude/longitude (accurate to 1-mile radius).
• Device & OS Intelligence: Browser fingerprints, OS version, and mobile carrier.
• Email/Phone/User Verification: Bundle with our suite for multi-factor fraud checks.

4. Customizable Rules Engine

• Set thresholds (e.g., block scores >75).
• Whitelabel IPs or integrate with SIEM tools like Splunk.
• Bulk Queries: Process up to 10,000 IPs per request for batch analysis.

5. Enterprise-Grade Security & Support

• API Keys with IP whitelisting and rate limiting.
• SOC 2 Type II certified; encrypted endpoints (TLS 1.3).
• 24/7 monitoring, SLAs up to 99.999%, and dedicated account managers for tiers above 1M queries/month.

All features include free testing credits and sandbox environments. Integrate in minutes—no hardware required.
