Information Security

As computerization and the growth of networks progress in our advanced information society, the threats of illegal / unauthorized access to our computer systems increase, requiring a well-organized, comprehensive management system for information security.

The Chiyoda Group’s Information Security System

The Chiyoda Group believes that the maintaining confidentiality and integrity of and maximizing the use of its own business and technical information resources entrusted to Chiyoda by its business partners such as clients, licensors and joint venture partners are fundamental to the Company’s reliability since its founding. Chiyoda has established its Information Security Management System (ISMS) based on the British Standards Institution (BSI) of the United Kingdom for BS7799:1999, since 2001, and has been certified by the world-renowned certification body for ISO/IEC 27001:2005, since 2007, and for ISO/IEC 27001:2013, since 2014.

Limited) that handle highly confidential technical information have acquired ISO / IEC 27001:2013 certification.
