Mass Adoption Achieves ISO Certification for Information Security and Privacy Protection

## Mass Adoption Significantly Strengthens Buckle Service Reliability with Acquisition of International Security Certifications Mass Adoption, which operates the brand growth platform 'Buckle,' has significantly enhanced service reliability by simultaneously acquiring ISO/IEC 27001 and ISO/IEC 27701 certifications, key international standards in information security and personal data protection. This achievement internationally recognizes Mass Adoption's technology-based safety and responsibility in handling customer data. ISO/IEC 27001 is a standard that evaluates a company's overall information security management system, encompassing a wide range of areas from information security policies to physical, administrative, and technical security. Furthermore, the acquired ISO/IEC 27701 is a specialized standard for personal data protection management systems, covering an organization's personal data management procedures, encryption, anonymization, and service safety. Mass Adoption met both of these strict criteria, demonstrating the highest level of information security and personal data protection capabilities. Buckle provides retention CRM and purchase conversion CRM solutions that help brands build long-term relationships with their customers. In this process, sensitive first-party data, such as customer experience, fandom, and behavioral data, which are core assets of brands, are handled. This dual certification signifies that the information system management level across all of Buckle's CRM services meets international requirements, providing a strong basis for brand partners to confidently entrust their customer data. Park Chan-woo, CEO of Mass Adoption, emphasized, "CRM is more than just sending messages; it's a strategy to build bonds and trust between brands and customers, and its foundation is the responsible storage and processing of customer information." He added, "With this certification as a stepping stone, Mass Adoption will serve as an even more trustworthy partner to foster brand growth together." Based on this international certification, Mass Adoption plans to not only advance its current CRM services but also apply the same strict information security and personal data protection systems to its upcoming 'Brand Intelligence Platform'. Through this, the company aims to further solidify its position as a strategic partner for brand growth, prioritizing data trust as its utmost value.
