Cacco、広告詐欺防止サービス「X-log」を開始

Cacco Inc., which provides the No. 1 fraudulent order detection service in Japan and contributes to the creation of a secure infrastructure for online shopping, is pleased to announce that it has acquired the “X-log” web advertising fraud prevention service business from Japan Claudia Co., Ltd. and has commenced providing the service today.

This service makes it possible to detect and reduce wasted advertising costs due to fraudulent clicks (ad fraud) at the ad acquisition stage. Combined with our existing “O-PLUX” service, we now have a system in place to seamlessly provide fraud prevention measures for online businesses, from advertising acquisition to login and payment.

Background: Approximately one in two e-commerce businesses feel that their advertising costs are a waste.

Domestic internet advertising spending is projected to reach a record high of 3,474.1 billion yen in 2024, making it an important means of attracting customers for companies. On the other hand, “ad fraud,” in which advertising fees are stolen through fraudulent ad clicks by bots or competitors, is becoming a serious problem.

In our own independent survey (an internet research targeting 553 fraud prevention personnel at e-commerce businesses), 48.3% responded that they “have felt that advertising costs were wasted,” highlighting this as a pressing issue on the ground.

Furthermore, research (IAS “Media Quality Report”) has shown that Japan has one of the highest ad fraud rates among major countries. In addition, measures to combat fraud are rapidly being institutionalized, such as the “Guidance for Advertisers, etc., for the Appropriate and Effective Delivery of Digital Ads” published by the Ministry of Internal Affairs and Communications in June 2025 and the certification system of JICDAQ (Japan Digital Advertising Quality Certification Organization). Our company has previously specialized in fraud detection (fraudulent logins, fraudulent transfers, fraudulent orders/payments) in the e-commerce and financial sectors. By adding “X-log,” which is at the advertising stage that is the entry point for customer acquisition, to our lineup, we aim to provide a “comprehensive fraud prevention solution” that supports the maximization of advertising effectiveness and the prevention of subsequent payment damage in a seamless manner.
