Leveraging the experience of Deloitte*, a market leader in security consulting on a global scale, DTCY will begin operations in June this year to accelerate the expansion of its cyber security business in Japan. The new company was initially launched with around 120 members of Deloitte Tohmatsu Risk Services Co., Ltd. (“DTRS“) and Deloitte Tohmatsu Consulting LLC (“DTC“), who currently engage in cyber security activities. DTCY plans to increase the number of employees in the future.
* Deloitte ranked #1 by Gartner in Security Consulting Services for the sixth consecutive year (2017)

In the era of IoT, where people, things, organizations, and social infrastructure connect across all boundaries, cyber security is one of the most important management issues of any organization, as well as a vital element in every business transformation. Through DTCY, Deloitte Tohmatsu Group is committed to providing support for business transformation aimed at improving corporate sustainable growth and competitiveness in terms of cyber security as the Deloitte Tohmatsu Group. From “Strategy” and “Secure” to “Vigilant” and “Resilient”, DTCY’s holistic approach will help companies with the knowledge and capabilities required to manage cyber risks.

DTRS already provides cyber security consulting services in both technology and management, such as strategy development, establishment of monitoring systems, incident response, and has supported clients 24 hours a day, 365 days a year through its Cyber Intelligence Center (CIC) in Yokohama, which is directly connected with Deloitte sites in more than 20 countries worldwide. DTC has strengths in strategic consulting focused on global business development of companies from the standpoint of cyber security, based on trends in the development of various standards related to cyber security such as the United States National Institute of Standards and Technology (NIST). By bringing together these professionals in DTCY, it can support C-suite executives through the development of a future-oriented security strategy to confront the evolution and complexity of cyber-attacks while at the same time leveraging deep knowledge of technology to solve problems in the field.

DTCY leads the industry as a group of specialists with cutting-edge knowledge in the cyber security area, and is the first to be chosen by clients. DTCY aims to be recognized as the company where the best people with diverse capabilities and skills gather. To this end, DTCY will build a talent framework focused on creating an environment in which a wide range of cyber security personnel can thrive and grow, from strategy consultants to product engineers and network engineers. In addition, DTCY will proactively provide opportunities for career development on a global scale through the provision of services to global clients in partnership with Deloitte member firms around the world. In addition, the Deloitte Tohmatsu Advanced Research Laboratory of Cyber Security (DT-ARLCS), which has been operated by DTRS, will continue under DTCY to research, verify and disseminate information on state-of-the-art security technologies and methods. The knowledge accumulated through the DT-ARLCS is not only used for the development and know-how of DTCY professionals, but also systematically analyzing and sharing the latest information on advanced security it can provide higher value to clients.
