Cacco Inc., a company supporting the safety of online transactions with AI and proprietary algorithms, announced that its fraud detection service 'O-PLUX' has been implemented at LIXIL Corporation's official online store, 'LIXIL Store,' contributing significantly to strengthening measures against fraudulent orders, including credit card fraud.

■ Background: Increasingly Sophisticated Fraud and the Limits of 3D Secure
Following a site integration in 2023, LIXIL's online store experienced a sharp increase in fraudulent credit card use. The methods were so sophisticated they could bypass the '3D Secure' identity verification service, with damages reaching several million yen per month. High-value, easily resalable items such as water filter cartridges, high-function shower heads, and the 'HOBOT' window-cleaning robot were primary targets. Staff were overwhelmed with over 30 minutes of daily manual checks and the work of halting shipments and recalling products, which strained core customer service operations.

■ Deciding Factor: A 97% Detection Rate Proven in Trial
While considering multiple countermeasures, LIXIL chose 'O-PLUX' for its reliable detection accuracy, which recorded a 97% block rate in a trial using actual order data. Other key factors were the transparency of blocking reasons, which provided operational confidence, and the speedy implementation, moving from consideration to full deployment in less than a month via CSV integration.

■ Results of 'O-PLUX' Implementation: Complete Elimination of Damages and Reduced Workload
Following the implementation, the LIXIL Store stopped receiving fraud confirmation calls from credit card companies, successfully suppressing damages. The 30+ minutes of daily manual checks and customer identity verification calls were reduced to zero, creating an environment where staff can focus on their primary duties.

■ Comment from Mr. Hirotaka Karimine, LIXIL Corporation
'With the growing sophistication of fraud, we implemented O-PLUX and have been able to completely eliminate damages. Moving forward, we believe it's crucial for e-commerce businesses, payment gateways, and security firms to unite and share information. By improving the accuracy of fraud prevention across the industry, we hope to build a safer e-commerce environment for everyone.'
