Case Study Release: Proactive Cybersecurity Defense Achieved Through Expert Outsourcing, Even with Limited Staff (Nanjyo Equipment Industrial Co., Ltd.)

Aminoya Co., Ltd. (Chuo-ku, Tokyo; hereinafter 'Aminoya'; Tokyo Growth Market: 4258) has released a case study on Nanjyo Equipment Industrial Co., Ltd., a company engaged in the development and manufacturing of automotive interior components. To address increasing cyber threats without a dedicated security team, Nanjyo adopted Aminoya's cloud-based CSIRT service 'SecuSapo' and the 'SentinelOne (EDR) Operation Service.' By outsourcing security operations to experts, the company achieved a proactive defense system that avoids overburdening internal staff.

Challenges Faced

- Limited staff handling multiple roles made it difficult to conduct specialized monitoring and operations

- Inability to keep up with high volumes of alerts, increasing the risk of missing critical incidents

- Frequent emergency incident responses disrupted scheduled work

- Ongoing anxiety about potential undetected breaches

Benefits After Implementation

- Centralized monitoring and response handled by experts, significantly reducing operational workload

- Detection and identification of unauthorized access attempts that would have otherwise gone unnoticed

- Emergency responses managed externally, enabling planned tasks to proceed as scheduled

- Clear identification of security improvement points through regular ASM and vulnerability assessments

Background of Implementation

Founded in 1915, Nanjyo Equipment Industrial Co., Ltd. is a long-established manufacturer whose core business includes the design, development, and manufacturing of automotive interior parts such as door trims. As a key player in the supply chain, maintaining information security is a critical management issue. However, the Information Technology Group within the IT Promotion Department handles server and network management, PC setup, and security with a small team, making it difficult to assign dedicated personnel. Feeling the limits in responding to increasingly sophisticated cyberattacks, the company made the decision to outsource security operations to external experts.
