ISO/IEC 27001 certification in Vietnam

ISO 27001 certification in Vietnam at a glance

The State Bank of Vietnam's Circular No. 09/2020/TT-NHNN sets out how banks, payment intermediaries and other covered institutions secure their information systems, including a rule that cloud providers they select hold a valid international certification for information security assurance. The circular does not name ISO/IEC 27001, but for a cloud, software or managed-service provider selling into Vietnamese finance it is the certificate most often put forward. The Law on Personal Data Protection No. 91/2025/QH15, in force since 1 January 2026, adds pressure on every organisation handling personal data of Vietnamese citizens. Certification is granted by a certification body after a two-stage audit of the information security management system and its Statement of Applicability; BoA lists information security management systems among its IAF MLA programmes. Sterling's Ho Chi Minh City office prepares the risk assessment, controls, evidence and internal audit, with Effivity and Sterling Academy included. Questions specific to Vietnam follow.

Who needs ISO 27001 in Vietnam, and what happens without it

In Vietnam the question rarely comes from a law. It comes from the buyer, the regulator or the partner that wants proof before it signs. These are the organisations that get asked.

• Cloud, data-centre and managed-service providers to Vietnamese banksCircular 09/2020 requires selected cloud providers to hold a valid international certification on information security assurance.
• Banks, payment intermediaries and credit information companiesCovered by the SBV's information system safety rules.
• Organisations processing personal data of Vietnamese citizensThe Law on Personal Data Protection requires protection measures, impact assessments and breach notification.
• Software and IT outsourcing firms in hi-tech parks serving overseas clientsCustomers request certified information security in procurement.

ISO 27001 requirements in Vietnam

Strip away the vocabulary and ISO/IEC 27001 requires a company to prove six things about how it protects the information it holds.

In Vietnam these six sit alongside the local laws and regulations listed under drivers below; one system can evidence both. The detail is on the global hub: ISO/IEC 27001 explained →

How long does ISO 27001 certification take in Vietnam?

There is no standard duration: it depends on your scope and on how much of the system already runs. In Vietnam these are the factors that set the timeline.

• Number of sites, data centres and cloud services in scope
• Maturity of risk assessment and Statement of Applicability
• Scheduling around the Tết break

Sterling agrees a dated plan with you on the discovery call, once the scope is known.

How much does ISO 27001 certification cost in Vietnam?

The cost has two parts: the consulting work to build and prove the system, and the certification body’s audit fees, which are quoted separately. In Vietnam these factors move both.

• Number of locations, systems and headcount in scope
• Technical remediation (logging, access control, backup)
• Certification body audit fees quoted separately from consulting
• Translation of documents between Vietnamese and English where auditors or parent companies need both

Sterling gives one customised, all-inclusive proposal after the discovery call, never before the scope is agreed.

ISO 27001 consultants and certification bodies in Vietnam

Two different organisations are involved. A consultant helps you build the system and prove it works; an accredited certification body then audits or assesses it and decides. Keeping the two separate is what makes the result credible to buyers and regulators.

• Check that the body’s accreditation or approval covers ISO 27001 and your sector, and that its certificates can be verified online.
• Ask the consultant how the local requirements in Vietnam are mapped into the same system, so nothing runs twice.
• Ask for client references in your sector; Sterling’s client letters are available on request.
• Agree who owns the evidence and the tool after the engagement; with Sterling the system stays yours, in Effivity.
