Why Vendor Data Security Assessments in Vietnam: Criteria and Periodic Execution must be handled early

This article analyses ‘Vendor Data Security Assessments in Vietnam’ under the law in force on 20 October 2026, moving from the governing provisions to a concrete sequence of action for the enterprise.
The provisions to master
Data protection responsibility, under the Personal Data Protection Law 91/2025/QH15 and Decree 356/2025/ND-CP, does not stop at paper policies: the enterprise must organise people and processes — designate capable data protection personnel or a department, bind processors by contract, and be able to demonstrate protection capability when the specialised authority inspects; this is the hardest transition for foreign-invested firms used to a centralised group model. Vendor data security assessment should be run by a foreign-invested firm as part of its duty to select a capable processor under Law 91/2025/QH15 and Decree 356/2025/ND-CP: criteria include independent certification and audits (ISO/IEC 27001, SOC 2), data storage locations, incident history, contract terms and Vietnam compliance support capability — international certification is important supporting evidence but cannot replace the firm’s own assessment, because responsibility toward Vietnamese authorities does not transfer with a certificate.
