At the time of its opening in August 2022, CMC Data Center Tan Thuan was the first data center in Vietnam to simultaneously hold two important Uptime Tier III certifications: Design and Construction. After two years, CMC's engineering team has further demonstrated to the Uptime Institute that Vietnamese data center operation capabilities have reached the highest level according to global standards, meeting all the rigorous criteria for evaluating the sustainable operation of data centers – Tier Certification of Operational Sustainability (TCOS) of the Uptime Institute. The Uptime TCOS certification, issued by the Uptime Institute, focuses on evaluating and certifying the sustainable operation of data centers. This certification not only examines the design and construction of the data center but also assesses operational and management aspects to ensure that the data center can maintain stable and continuous operation over the long term. The Uptime Institute is a leading global organization with a recognized certification system that serves as a global benchmark for assessing the overall readiness and performance of data centers, from design and construction to operation. According to the Uptime Institute, even data storage powerhouses in Asia such as Singapore, Malaysia, Hong Kong (China), and Japan still lack Tier 3 TCOS data centers. Tan Thuan Data Center proudly stands among the few data centers in Asia to simultaneously hold all three certifications: Design, Construction, and Operation.

According to Mr. Dang Tung Son, Deputy General Director and Director of Sales and Marketing at CMC Telecom: "Becoming the first unit to achieve TCOS and possessing all three Uptime certifications (TCCF, TDD, and TCOS) affirms our commitment to building a leading digital infrastructure in the region, representing a strong shift in CMC Telecom's journey to becoming a Comprehensive Services Provider. Operational upgrades are also part of our strategy to deliver excellent customer experiences, providing high-quality, internationally standardized services to leading financial institutions, banks, and large enterprises in the country and the region.” CMC Telecom currently boasts experts holding numerous international certifications, including two CDCE (Certified Data Center Expert) certifications, considered "DC PhDs," and a series of CDCP, CDRP, CDCS, CDFOM, and CDMS certifications for experts in Operations, Risk Management, and Data Center Transition. Mr. Le Minh Hieu, Director of the Data Center Division at CMC Telecom and one of the first three Vietnamese individuals to hold the CDCE certification, shared: “Investing in people is the prerequisite for creating a globally standardized data center. We would like to thank Uptime for its thorough and rigorous evaluation system, which has given CMC's technical team the opportunity to transform through challenges. CMC Telecom has learned a great deal from these tests, understanding the core principles of sustainable operation according to the highest international standards.” In June 2024, CMC Data Center Tan Thuan became the first data center in Vietnam to achieve Level 4 Information System Security certification, assessed by the Ministry of Information and Communications in coordination with the Ministry of Public Security and the Ministry of National Defense. CMC Telecom's Level 4 certified data center ensures it can serve large-scale users with specific needs, such as public administration, government, finance, banking, and e-commerce organizations. In 2008, CMC Technology Group established CMC Telecom with the mission of being an ISP, an internet service provider. After 16 years, CMC Telecom is now a Comprehensive Service Provider, offering connectivity, data center, cloud/multi-cloud, information security, and managed services, focusing on serving leading enterprise clients in high-demand sectors such as finance and banking, energy, manufacturing, retail, and logistics.
