In recent years, cyber attacks have become increasingly sophisticated and malicious, and the risk of leakage of personal and confidential information has become a major management issue in corporate activities. Protecting all information held, including information assets entrusted by customers and business partners, is an extremely important social responsibility that companies must fulfill. Our company promotes the following initiatives and strives for the continuous enhancement of our information security framework.

Specialized Team for Strengthening Information Security Measures

We have established a dedicated team to professionally promote and oversee information security measures, aiming to enhance security levels company-wide. We constantly monitor the latest trends in information security threats and technologies and have built a system to plan and implement rapid and effective reports and countermeasures.
We have established and thoroughly enforce information security policies, such as standards for PC use, smart device use, and antivirus measures.
There were zero major information incidents in FY 3/25.

Raising Awareness regarding Information Security among Employees and Related Practical Training

We conduct ongoing security education annually for all executives and employees through e-learning and other methods. We also regularly conduct practical phishing email response training designed to simulate increasingly sophisticated targeted attacks. Through these efforts, we aim to raise each employee's awareness of information security and improve their ability to respond in the event of an incident.

Defense and Monitoring Using Advanced Technologies

We employ advanced multi-layered defenses such as firewalls and an intrusion detection system and have established a system for round the clock monitoring of information security. This enables early detection and rapid response to unknown threats and sophisticated cyberattacks, greatly strengthening the overall defense of our information systems. POC will continue to regularly review and strengthen information security measures to respond appropriately to changes in the internal and external environment and new threats, thereby earning the trust of our customers, business partners, and society.

We position the proper management of intellectual property as an essential activity for the development of our business. In technological fields necessary for business development, we actively promote the acquisition of intellectual property rights. Regarding infringement of rights by others, we strive to maintain our intellectual property rights by responding as necessary in accordance with relevant laws and regulations. When developing new technologies, we also conduct appropriate surveys of similar technologies to respect third-party intellectual property rights.
