Notice Regarding Acquisition of Information Security Management System (ISMS) Certification

Artisan Co., Ltd. (Headquarters: 6F Aizawa Chofu Building, 4-5-1 Fuda, Chofu-shi, Tokyo; Representative Director: Saiki Koyama; hereinafter "the Company"), a provider of SaaS for public transportation and Microsoft cloud services, is pleased to announce that it obtained certification for the international standard for Information Security Management Systems (ISMS), "ISO/IEC 27001:2022 + Amd 1:2024," on March 23, 2026.

Background of ISMS Certification Acquisition The Company develops enterprise cloud services centered on the Microsoft cloud and provides public transportation DX solutions, such as the bus location system "Bus Yoho," to local governments and bus operators nationwide. These services contain critical information, including boarding/alighting data, operational information, and customer business data; we recognize that ensuring information security is a fundamental responsibility to our customers and users.

Based on this recognition, we worked company-wide to build an ISMS, leading to the acquisition of ISO/IEC 27001:2022 + Amd 1:2024 certification. We will continue to strive to maintain and improve our information security levels through continuous improvement, ensuring the provision of services that can be used with peace of mind.

What is ISMS? ISMS stands for Information Security Management System, a framework for managing an organization's information security. The "ISO/IEC 27001" certification we have acquired is an international standard for ISMS that defines a framework for ensuring and maintaining the three elements of information security (confidentiality, integrity, and availability).

In the ISMS certification process, an independent third-party ISMS certification body evaluates an organization's security measures and management status from an impartial perspective. ISMS certification serves as proof that an organization has an appropriate security management system in line with "ISO/IEC 27001."

About "SecureNavi," the SaaS Used for ISMS Certification We acquired ISMS certification using SecureNavi, an ISMS/P-Mark automation tool. SecureNavi is a cloud service that streamlines efforts related to ISMS and P-Mark certifications and improves an organization's information security level.

It improves the productivity of personnel in charge while realizing the construction of an information security system that is optimal for the company and does not become a mere formality.
