When evaluating data center providers, many businesses ask: “Are you ISO 27001 certified?” — but not everyone fully understands what that certification actually means or why it matters.

---

What Is ISO/IEC 27001?

ISO/IEC 27001 is the international standard for Information Security Management Systems (ISMS), published by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). It is the most widely recognized standard for information security management in the world.

The current version — ISO/IEC 27001:2022 — has been updated to address the increasingly complex cybersecurity risks organizations face today.

What Does Certification Require?

Achieving ISO/IEC 27001 requires an organization to build and maintain a comprehensive information security control system — covering not just technology, but also processes, people and governance policies. This includes:

• Systematically identifying and assessing information security risks
• Implementing controls to mitigate those risks
• Training staff and fostering a security-aware culture
• Conducting regular internal audits and continuous improvement
• Undergoing independent assessment by an accredited third-party certification body

Importantly, ISO 27001 is not a one-time achievement — organizations must maintain and renew their certification periodically to ensure their systems remain current and effective.

Why It Matters for Financial Institutions

For financial organizations, customer data and transaction records are core assets requiring the highest level of protection. ISO 27001 provides a globally proven security risk management framework — and serves as concrete evidence of compliance for internal audits, regulatory requirements and international partners.

Placing systems in an ISO/IEC 27001-certified data center means your infrastructure is protected not only by physical safeguards, but by an entire system of security processes and controls independently verified by a third party.

In recent years, demand for data infrastructure in Vietnam has been growing faster than ever. The wave of digital transformation, the explosion of AI, and the Government’s policies promoting the digital economy are putting increasing pressure on enterprise IT infrastructure — and Data Centers have become the center of it all.

What Is Driving Growth?

Widespread digital transformation. From banking and insurance to government agencies, most organizations are digitalizing their operations. This drives a sharp increase in data storage and processing needs — requiring IT infrastructure that is more stable and secure than ever before.

AI and big data. AI applications, real-time data analytics, recognition systems, and automation all require powerful computing infrastructure with low latency. Traditional server rooms struggle to meet these demands at scale.

Local data storage regulations. Regulations increasingly require data from financial institutions, banks, and government agencies to be stored on infrastructure located within Vietnam — driving demand for high-quality domestic Data Centers.

What Do Businesses Need from a Modern Data Center?

High availability. Uptime guaranteed by SLA, with redundant power and cooling infrastructure — ensuring systems operate continuously regardless of what happens.

Multi-layer security. Multi-tier physical access control, 24/7 CCTV monitoring, and international security certifications — meeting increasingly strict compliance requirements.

Flexible connectivity. Multi-carrier support, DC-DR connectivity, high bandwidth — reducing dependency on a single provider and increasing redundancy.

Managed operations. On-site NOC, Remote Hands, and regular operational reporting — giving businesses peace of mind without needing to deploy dedicated monitoring staff.

Telehouse Vietnam — Ready for the Digital Era

Founded in 2010, Telehouse Vietnam has continuously expanded its capacity to meet the market’s growing demands. In 2023, the 4th Floor Data Hall officially came into operation — bringing the total area to over 1,600m² with next-generation infrastructure, Dual-Power Feeds 2N, and N+2 cooling systems.

Built on the foundation of the Telehouse Global/KDDI ecosystem — 47 Data Centers across 10+ countries, serving over 3,000 customers worldwide — Telehouse Vietnam brings international operational standards to Hanoi, serving both domestic businesses and international organizations with data infrastructure needs in Vietnam.

When IT systems go down, everything stops — transactions, operations, customer data. That’s why more and more businesses in Vietnam are asking a serious question: is maintaining an in-house server room still the optimal choice?

Power costs, cooling, security, round-the-clock staffing, risks of outages or fire… these are silent burdens that many organizations continue to carry. Meanwhile, a more efficient solution has been operating reliably in Vietnam for over 16 years: Colocation at a professional Data Center.

What Is Colocation?

Colocation is a service that allows businesses to place their servers, network equipment, and storage systems within the infrastructure of a professional Data Center — rather than building and operating their own server room.

Simply put: the hardware is still yours, but the entire physical infrastructure — power, cooling, security, and network connectivity — is managed by the Data Center.

Depending on your needs, businesses can rent space by unit:

• 1U / 2U — for individual devices
• Half Rack / Full Rack (42U) — for mid to large-scale systems
• Private Cage / Suite — for businesses requiring full control and completely separate space

5 Reasons Businesses Should Consider Colocation

World-class infrastructure — no capital investment required. Building a server room that meets continuous operation standards requires significant investment in UPS systems, backup generators, precision cooling, fire suppression, CCTV, and multi-layer access control. With Colocation, all of this infrastructure is already in place and operated by a professional technical team to international standards — from day one.

High uptime with clear SLA commitments. Downtime is a risk no business can afford to ignore. A professional Data Center guarantees 99.982% infrastructure availability — equivalent to less than 1.6 hours of total downtime per year. This is a level of assurance that most in-house server rooms simply cannot match.

Full control over your equipment — unlike Cloud. Unlike Cloud solutions, Colocation means businesses own and directly control their hardware. This is critical for financial institutions, banks, and government agencies with strict requirements around data compliance, system auditing, and data sovereignty.

Multi-carrier connectivity at high speed. A carrier-neutral Data Center supports simultaneous connections to multiple ISPs including Viettel, VNPT, FPT Telecom, CMC Telecom, HGC, and DSTEL. This reduces dependency on a single provider, optimizes bandwidth, and ensures connection redundancy.

Cost optimization — converting CAPEX to OPEX. Instead of a large one-time investment in fixed infrastructure, Colocation allows businesses to pay only for the rack space and actual power consumed. When expansion is needed, simply add more racks — no need to build additional server rooms or upgrade power and cooling systems.

When Is Colocation Right for Your Business?

Colocation is particularly suitable if your organization is in one of these situations:

• Systems require high availability and business continuity (banking, finance, insurance, telecommunications)
• The in-house server room no longer meets operational standards or is at capacity
• The business needs to scale infrastructure quickly without additional physical investment
• There are data security compliance requirements that need an internationally certified environment
• Building or upgrading a DC-DR solution — primary and disaster recovery data centers
