Mercart Inc. (Headquarters: Minato-ku, Tokyo; President and CEO: Akihiko Watanabe; hereinafter, Mercart) has achieved compliance with "v4.0.1," the latest version of "PCI DSS (Payment Card Industry Data Security Standard)," an international security standard for the credit card industry, for its cloud EC platform "Mercart."
This compliance ensures that Mercart provides the highest level of payment security demanded by mid-sized and large enterprises. This allows businesses to eliminate concerns about information safety and focus more on "proactive business growth" through AI utilization and advanced marketing strategies. Mercart strongly supports businesses as a trusted infrastructure, protecting customer payment information from increasingly sophisticated cyberattacks while enabling them to maximize technology to create new value.
■ Supporting Ambitious EC Strategies from the Ground Up with Unwavering "Safety"
Currently, in the EC market, while DX (Digital Transformation) through AI personalization and data utilization is accelerating, countermeasures against sophisticated cyberattacks and unauthorized access have become the most critical management issue.
Mercart advocates for the coexistence of "SaaS agility" that can quickly respond to rapidly changing market environments and "overwhelming robustness" demanded by enterprise companies. This compliance with "PCI DSS v4.0.1," the latest international standard, is not merely an enhancement of security measures but fulfills Mercart's responsibility as a "trusted infrastructure" to protect customers' brand value and support ambitious EC strategies from the ground up.
■ Benefits for Adopting Companies from "PCI DSS v4.0.1" Compliance
1. Avoiding the "Worst-Case Scenario" and Ensuring Business Continuity
In the unlikely event of a security incident such as an information leak on an EC site, PCI DSS compliance may be a condition for continuing or resuming card payments. Handling such post-incident responses in-house can involve enormous investigation costs and, in some cases, several months of payment suspension, which could jeopardize the very existence of the business.
Choosing Mercart, which complies with the latest standards, as your platform is the most rational and robust preparation to maintain payment infrastructure and secure your brand's lifeline even in such "unlikely" situations.
2. "Guaranteeing Trust" and Brand Protection with the Highest Level of Security
Information leaks can lead not only to significant compensation but also to the instantaneous loss of customer trust built over many years. The fact that Mercart meets "PCI DSS v4.0.1," considered the world's strictest payment security standard, is proof of the "highest level of integrity" towards customers and business partners.
Especially for mid-sized and large enterprises that prioritize compliance, Mercart's compliance functions as a "shield of trust" that thoroughly protects brand value from invisible threats.
■ Future Outlook
Mercart will continue to pioneer "next-generation EC experiences," including the utilization of AI agents. All these innovative functions will be realized on the unwavering foundation of security provided by the newly achieved "PCI DSS v4.0.1" compliance.
Moving forward, we will continue to integrate technology and security at a high level, creating the future of business together with our clients as their trusted partner.
