## Introduction of company

TSUZUKI DENKI helps clients to enhance their corporate value through solutions based on "ICT Solutions x Electronic Devices". In January 2018, the company developed "Tsuzuki CSIRT*” that protects security in normal times for the systems delivered to clients and responds quickly in case of an emergency. The company launched in-house application vulnerability scanning operations as part of its security risk management in normal times. After adopting Vex, the full-scale operations got ahead in a short period of time and raised security awareness among developers.

*CSIRT＝Computer Security Incident Response Team

Challenges

- Each project team had to be responsible for the system security management, and no company-wide common tool was deployed.

Benefits

- Increased security awareness among the developers and improved secure design and secure coding techniques.
- They can even discover bugs unnoticed by unit tests prior to release, further improving the quality of system development.
