Takenaka Corporation has defined its vision for 2030 through digital transformation and is advancing reform activities that integrate its digital division with all business units.
The company has built a Building 4.0TM digital platform to centrally accumulate all data related to business operations—from sales, design, estimation, engineering, construction management, to facilities management services—and administrative functions such as HR and accounting. This platform enables advanced utilization of data through AI and other technologies, driving productivity improvements and the creation of new value.
As part of its digital transformation efforts, Takenaka is promoting collaboration with stakeholders including clients and partner companies, resulting in an increase in systems used jointly with external parties. Consequently, the need to proactively defend all systems from external attacks has grown.
While the company has previously conducted vulnerability detection for externally exposed systems, some detections—such as open ports—were performed manually, which led to delays in identifying mistakenly exposed ports.
Takenaka confirmed ongoing attempts of unauthorized access to such assets and recognized the limitations of manual detection and response. This prompted the company to consider the importance of automated vulnerability detection through Attack Surface Management (ASM), leading to the adoption of DeCYFIR.
With DeCYFIR, Takenaka can now automatically detect not only vulnerabilities in externally exposed assets but also open ports, significantly improving real-time detection capabilities.
Thanks to DeCYFIR’s high detection accuracy and CYFIRMA’s smooth onboarding support, the company was able to identify previously unnoticed exposed assets.
Given the nature of the construction industry, where numerous projects are simultaneously underway at various sites, detecting vulnerabilities across all assets—including those at the site level—is challenging. Takenaka has found DeCYFIR’s ASM functionality to be highly effective in addressing this industry-specific challenge.
Takenaka Corporation selected DeCYFIR for its excellent cost performance and user-friendliness. Although the company had considered adopting the platform three years ago, it ultimately decided against it at the time.
This time, however, the platform’s usability has significantly improved, and its high-performance vulnerability detection and robust support system—including recommendations for countermeasures and updates on the latest security trends—led to a comprehensive evaluation and decision to implement DeCYFIR.
Mr. Masanori Suzuki from the Digital Division of Takenaka Corporation commented:
“As our digital environment becomes increasingly sophisticated and complex with the advancement of DX, the importance of fundamental security measures such as asset management and vulnerability management continues to grow.
CYFIRMA plays a vital role in ensuring the thorough implementation of these basic measures, thereby enhancing the effectiveness of our security strategy.”
