Company

DHgate is a leading cross-border e-commerce platform with business coverage spanning 200+ countries and regions, DHgate serves as a vital bridge connecting SMEs with international buyers. As of 2025, the platform boasts over 2.6+ million registered suppliers, an annual average of 34+ million online products, and more than 77+ million registered buyers. With its highly efficient operations, an order is placed on DHgate every 1.34 seconds, highlighting its significance and influence in global trade.

Challenges

• Large-Scale Automated Attacks Disrupting Platform Integrity
• Scalping and Abuse of Promotional Offers
• Security Measures Compromising Global User Experience

As a global B2B e-commerce leader connecting millions of suppliers and buyers worldwide, DHgate faced multifaceted challenges in scaling its platform while safeguarding its ecosystem. Operating across 200+ countries, the platform’s open nature and fragmented transactions made it a prime target for sophisticated cyber threats.

During peak shopping seasons such as Black Friday, DHgate experiences a dramatic surge in global transactions that not only fuels growth but also exposes the platform to increasingly sophisticated security threats. The rapid influx of orders amplifies vulnerabilities, with fraudulent activities—such as fake registrations and manipulated transactions—posing significant risks to data integrity and financial stability. Malicious actors exploited its high-traffic infrastructure, deploying automated bots to scrape pricing data, launch credential-stuffing attacks, and generate fake accounts for fraudulent transactions, while the exploitation of promotional offers, often manifested as discount abuse, further complicates the secure operation of the platform.

These activities not only risked supplier competitiveness and buyer trust but also strained the platform’s ability to balance security with seamless user experience. For instance, traditional CAPTCHA systems often disrupt legitimate buyers in regions with low-end devices or language barriers, increasing checkout abandonment rates. Meanwhile, evolving fraud tactics, such as AI-driven bots mimicking human behavior, outpaced static security measures, leaving gaps in real-time threat detection. The stakes were high: a single oversight could lead to revenue loss, reputational damage, or regulatory scrutiny in diverse markets.

Solution

Upon identifying existing security vulnerabilities and the inadequacies of previous preventive measures, DHgate sought a solution that could balance user experience with bot protection against various security threats. The operation and maintenance team desired a comprehensive safeguard across multiple user interactions—including registration, login, and purchasing—while minimizing false positives and disruptions to their global user base. They turned to GeeTest and swiftly recognized that its CAPTCHA, powered by advanced artificial intelligence and ML technologies, was the ideal solution.

By deploying GeeTest CAPTCHA across these critical touchpoints, DHgate effectively intercepted anomalous users, thereby securing its business operations.

Backend Dual Security & Domain Whitelisting

GeeTest CAPTCHA employs AI-powered behavior analysis and dynamic security defenses to secure DHgate’s platform during registration, login, and order placement. Features like dual back-end configuration and domain whitelisting help block credential-stuffing attacks, enforce parameter validity checks and restrict unauthorized access. These measures minimize false positives while effectively blocking malicious activities.

Proactive Monitoring and Rapid Response

Automated log pushes with granular insights (IPs, timestamps, user actions) to detect anomalies. The log query and push function enables DHgate's team to analyze user behavior, detect anomalies, and respond swiftly to potential threats. Regular log push notifications and detailed data logs ensure timely issue tracking, minimizing business disruptions and enhancing operational efficiency.

Global Multi-Language & Distributed Nodes

GeeTest CAPTCHA v4’s multilingual support and globally distributed service nodes reduce latency, streamline verification, and cater to DHgate's diverse international user base. The user-friendly slider puzzle CAPTCHA further enhances the shopping experience, boosting conversion rates while maintaining strong security.

Result

• Significantly reduced bot attacks and account theft.
• 40% Faster incident response and improved security efficiency.
• Reduced global user verification time within 1 second

Upon deploying GeeTest CAPTCHA, DHgate experienced a significant reduction in bot traffic and fraudulent activities. This deployment dramatically reduced server overload and stabilized platform reliability. High-risk operations, such as payment processing and coupon collection, now operate uninterrupted by automated attacks during peak shopping events like Black Friday, when traffic surges can heighten the risk of malicious attacks. With harmful traffic effectively blocked, DHgate regained accurate insights into genuine user behavior, empowering the team to make data-driven decisions confidently.

No deployment is without challenges, especially when preparing for high-demand events where traffic surges can heighten security risks. In after-sales service, GeeTest's support team responded swiftly—analyzing issues, collaborating closely with DHgate to test adjustments, and deploying necessary updates without delay. GeeTest's CAPTCHA ability to adapt to evolving threats and provide real-time mitigation ensured that DHgate's platform remained secure in an ever-changing threat landscape. “Their proactive and responsive approach was critical to overcoming these challenges,” said a DHgate representative.

Beyond security, GeeTest enhanced global accessibility with localized solutions—such as Arabic slider puzzles and culturally tailored image challenges—that slashed verification failures in non-English markets and boosted cross-border seller sign-ups by 18%. These optimizations, combined with a multi-layer fallback system for low-bandwidth regions, improve verification success rates across devices.
