Our approach to information security

Basic Policy

In January 2020, Mitsubishi Electric reported a data leak incident caused by unauthorized access to its system, which has resulted in inconvenience and concern for customers and society. After also reflecting on guidance from the Personal Information Protection Commission received in December 2019 concerning the handling of personal information obtained through recruitment activities, the Mitsubishi Electric Group will continue to strengthen its information security measures* to prevent such a situation from occurring again. We also will strengthen the measures considering the general trend toward teleworking and cloud-based business models.

Mitsubishi Electric manages confidential corporate information relating to sales, engineering, intellectual property, and other areas, as well as information entrusted to the company by its customers and stakeholders. This is carried out based on the Declaration of Confidential Corporate Information Security Management established in February 2005. In light of events in fiscal 2019, we will once again work to increase awareness of this declaration within the Mitsubishi Electric Group and strive to protect and manage information even more carefully.

  • * Information security measures: These include technical measures from the four perspectives of intrusion blocking, containment, leak prevention, and global response, as well as human resource measures such as enhancement of employee training, and organizational measures on operation quality improvement, including thorough document management and framework upgrading.
