BuySell Technologies Upgrades to Latest Information Security Standards

BuySell Technologies Enhances Information Security with ISO Certification



In a move to reinforce its commitment to safeguarding its clients’ and employees’ data, BuySell Technologies has announced the successful transition to the latest international standard for Information Security Management Systems (ISMS), specifically ISO/IEC 27001:2022 and JIS Q 27001:2023. This upgrade represents a significant step in enhancing the company’s security management protocols and ensuring robust protection against evolving cyber threats.

Background of ISMS Certification Renewal


BuySell Technologies, which operates the comprehensive reuse service platform, BuySell, handles sensitive information from numerous customers and partners as part of its reuse business. Recognizing the importance of maintaining high standards of information security, the company first acquired the ISMS certification ISO/IEC 27001:2013 in 2023. The recent transition to the ISO/IEC 27001:2022 standard serves to strengthen the governance of the company’s information security management by integrating additional protective measures in response to contemporary cyber threats and technological advancements.

The assessment for the new ISMS certification confirmed that BuySell Technologies' management protocols are in full compliance with the latest requirements. This was conducted during a thorough examination by BSI Group Japan, which is a reputable certifying body committed to overseeing the highest standards in various industries.

Understanding ISMS


ISMS, short for Information Security Management System, is a systematic approach designed to manage sensitive company information, ensuring its confidentiality, integrity, and availability. In simpler terms, it encompasses processes and policies that prevent data breaches, ensure data accuracy, and provide timely access to information for authorized personnel.

The Importance of ISO/IEC 27001:2022


The ISO/IEC 27001:2022 standard sets forth guidelines for establishing, implementing, maintaining, and continually improving an ISMS. Its Japanese counterpart, JIS Q 27001:2023, was developed specifically for the domestic context, ensuring that the content mirrors the international standard with localized applicability. Compared to its predecessor, the latest version emphasizes enhanced measures in response to challenges such as cloud computing, remote work dynamics, personal data protection, and effective countermeasures against cyberattacks.
