In the context of Vietnamese Government’s strategy to transform data into a national asset, and with the enactment of Personal Data Protection Law 2025 (effective 01 January 2026) and Cybersecurity Law 2025 (effective 01 July 2026), protecting personal data has become a legal obligation for all businesses in Vietnam. Accordingly, businesses may comprehensively change their methods of collecting, storing, and processing information to ensure strict compliance with legal regulations on personal data. Based on this, this article will propose an action plan for FDI businesses, domestic businesses, and startups to implement compliance in a timely and effective manner.
First and foremost, it’s important to emphasize the far-reaching impact of Personal Data Protection Law compliance on every aspect of a business. Specifically, (i) Operational procedures: Businesses are required to review and adjust processes from marketing, sales to human resource management to meet the law’s requirements; (ii) Costs and resources: Compliance with personal data protection laws requires costs for legal consulting, upgrading IT systems, and personnel training; and (iii) Trusted Business Opportunities: Businesses that effectively comply with Personal Data Protection law not only mitigate legal risks but also build strong customer trust and create a sustainable competitive advantage in the market.
Compliance with personal data protection is not just a rigid, one-size-fits-all approach, but rather needs to be tailored to a specific operating model for each organization.
- – For FDI businesses and Multinational Corporations, the top priority is to closely monitor cross-border data flows, especially information exchange with parent companies or global service providers. These businesses need to focus on developing personal Data Processing Impact Assessment reports (DPIA), establishing standardized data transfer terms, and ensuring internal security standards to meet Vietnamese legal requirements while being compatible with international practices and standards.
- – Domestic businesses should prioritize ensuring the validity and transparency of user consent collection (data subject consent), from website interfaces to offline forms. At the same time, these businesses must establish a process for timely response requests for the exercise of data subject rights and invest in security commensurate infrastructure with their operational scale.
- – For Startups and Technology Companies, while they may receive some compliance exemptions during the initial stage, these exceptions will not apply if the entity handles sensitive data or processes data on a large scale. Therefore, applying the “Privacy by Design” principle from the outset not only optimizes the system structure but also a smart strategy to save compliance costs and minimize legal risks later.
Regardless of size or type of operation, establishing a standardized process is mandatory for businesses to ensure compliance with legal regulations on personal data protection and data risk management. The following six-step roadmap will help businesses translate these considerations into practical action:
- Step 1: Assess current state and Data Mapping
This is a fundamental step to help businesses fully identify the data assets they hold. Businesses need to conduct a detailed inventory of all types of data being collected, from basic data to sensitive data such as financial and health data. Based on this, clearly identify the data flow: from the source of collection, individuals, departments with access rights to sharing with third parties or transferring data abroad. At the same time, businesses must clearly define their legal role as the Controller, Processor, or Co-controller to apply appropriate responsibilities.
- Step 2: Build an Internal Legal Framework
Businesses need to review and finalize their internal regulations system to create a solid legal basis for data processing activities, including:
- – Data Protection Policy (Privacy Policy): Publicly disclose on the website/ app the purpose, scope of processing and rights of data subjects.
- – Consent Collection Mechanism: Redesign forms and checkboxes to ensure “voluntary, affirmative, and specific”.
- – Contracts and Agreements: Add Confidentiality Clauses to Employment Contracts and sign Data Processing Agreements (DPAs) with service providers (Cloud, Agency).
- Step 3: Complete the Impact Assessment Report:
This is a mandatory administrative obligation to prepare for serving the inspection and monitoring by the Department of Cyber Security and Hi-Tech Crime Prevention – Ministry of Public Security. Businesses need to prepare a Data Processing Impact Assessment Report (describing risks and mitigation measures) and a Data Transfer Report if international servers are used. These reports must be constantly updated to reflect changes in the actual processing procedures.
- Step 4: Deploy Technical and Organizational Measures
To ensure regulations don’t remain just on paper, businesses need to deploy a comprehensive set of enforcement measures, including:
- – Delegation of Data Protection Officers (DPO): Establish a department or individual responsible for data protection (mandatory for sensitive data).
- – Technical Measures: Deploy Implement Data Encryption, Multi-factor Authentication (MFA), and “Need-to-know” access control.
- – Incident Response: Develop scenarios and rapid response procedures to ensure notification to authorities within 72 hours of a data leak.
- Step 5: Training and Awareness
People are often the weakest link in security, therefore building a security culture through regular training for employees on legal regulations and risk identification is crucial. Simultaneously, it is necessary to establish a standard data deletion process when data is no longer needed or when employees leave the company to optimize storage space and minimize legal liability.
- Step 6: Regular Monitoring and Inspection
Finally, compliance must be maintained through regular internal inspections and reviews (every 6 months or 1 year) to ensure that processes continue to operate correctly. At the same time, businesses should proactively monitor the latest guidance documents from relevant authorities to promptly adjust the system according to changes in the law.
In the context of an increasingly stringent legal framework on personal data protection, compliance is not only a legal obligation but also a key factor for businesses to build trust with their customers and partners. Enterprises should proactively implement an appropriate action roadmap, integrating risk management, technology, and personnel training, in order to ensure sustainable compliance, mitigate legal risks, and enhance business value in the digital environment.
