During its periodic surveillance audit, QTSC was assessed by TÜV NORD, an international certification body, which confirmed the continued validity of its ISO certifications in quality, environmental, energy, and information security management. This outcome reaffirms QTSC's ongoing commitment to standardizing management processes, enhancing service quality, and continuously improving its operations in line with international standards.
The surveillance audit covered six standards: ISO 9001:2015 for quality management systems; ISO 14001:2015 for environmental management systems; ISO 50001:2018 for energy management systems; ISO/IEC 27001:2022 for information security management systems; ISO/IEC 27017:2015 for information security controls for cloud services; and ISO/IEC 27018:2019 for the protection of personally identifiable information in public cloud environments.
Through document reviews, assessments of compliance with established procedures, and on-site evaluations at QTSC, the TÜV NORD audit team identified several good practices in management and operations. Notably, QTSC has maintained good 5S practices for three consecutive years, contributing to a well-organized, professional work environment and greater operational efficiency.
In particular, the audit team recognized QTSC's leadership commitment and active involvement in implementing the information security management system. This was demonstrated through the establishment of policies, setting of objectives, allocation of appropriate resources, promotion of risk-based thinking, and commitment to continuous improvement. These factors help ensure consistent implementation of the information security management system and its integration into QTSC's day-to-day management and operations.
Maintaining the validity of its ISO certifications through periodic surveillance audits during the three-year certification cycle demonstrates QTSC's consistent application of international management standards. It also provides a foundation for QTSC to further refine its processes, optimize resource utilization, strengthen information protection, and enhance service quality.
Moving forward, QTSC will continue to build on these achievements, drive continuous improvement, and enhance the effectiveness of its management systems. These efforts aim to deliver high-quality, secure digital technology infrastructure and services that meet the growing demands of customers, businesses, and partners.
