Vietnam Issues Cybersecurity and Personal Data Protection Sanctions Decree

Subscribe to Updates

Vietnam has enacted a new decree establishing administrative penalties for violations in the fields of cybersecurity and personal data protection. Decree No. 330/2026/NĐ-CP (Decree 330), issued and effective from August 19, 2026, provides a detailed sanctions framework for noncompliance with the Law on Personal Data Protection (including its implementing regulations under Decree 356/2025/ND-CP) and the Law on Cybersecurity, together with their guiding decrees.

The issuance of Decree 330 signals that the practical grace period previously perceived by many businesses may be drawing to a close, with active regulatory enforcement in these areas expected to commence in earnest.

Scope and Key Provisions

Decree 330 has extraterritorial effect and applies to both onshore and offshore companies. For offshore companies, it applies to those that (1) provide telecommunications, internet, online-content, information-technology, cybersecurity, or cross-border services and (2) are involved in or related to the processing of personal data of Vietnamese citizens and certain other people of Vietnamese origin.

Decree 330’s key provisions cover the following areas:

  • Administrative penalties for violations relating to the protection of national security and public order in cyberspace, including the dissemination of unlawful, false, or unverified information.
  • Sanctions for cyberattacks, unauthorized access, introduction of harmful code or programs, and failure to cooperate with specialized cybersecurity forces.
  • Sanctions for personal data protection violations, such as consent, cross-border data transfers, impact assessments, breach notification, and data-subject rights, among others—with maximum fines of up to 5% of an organization’s preceding-year revenue for cross-border transfer violations, or up to VND 3 billion for other data-protection breaches.

Personal Data Protection Penalties

The key sanctions for personal data protection violations are as follows:

  • Consent violations: Fines of up to VND 70 million (approx. USD 2,642), plus potential additional sanctions and remedial measures including irreversible deletion of personal data collected without consent and confiscation of illegal profits.
  • Data breach notification violations: Fines of up to VND 80 million (approx. USD 3,019), with potential remedial measures including mandatory breach notification and implementation of prevention and remedial measures as directed by the regulator.
  • Data processing impact assessment (DPIA) violations: Fines of up to VND 100 million (approx. USD 3,774), with potential remedial measures including mandatory DPIA submission and suspension of personal data processing until the filing obligation is successfully completed.
  • Cross-border transfer impact assessment (TIA) violations: Fines of up to 5% of preceding-year revenues or up to VND 3 billion (approx. USD 113,208), with potential additional sanctions and remedial measures including mandatory TIA submission and suspension of cross-border personal data transfers until the filing obligation is successfully completed.
  • Data protection officer and department appointment violations: Fines of up to VND 30 million (approx. USD 1,132), with potential remedial measures including mandatory appointment of a qualified person and mandatory issuance of policies and documents relating to personal data protection responsibilities.

Transitional Provisions

Decree 330 includes a transitional clause including a provision that where a cybersecurity or personal data protection violation was committed before Decree 330 took effect but is only discovered, or remains under review or resolution, after that date, the sanctions regime in force at the time of the violation will generally apply. However, where Decree 330 imposes no liability or lighter liability for the same conduct, companies may invoke the more favorable provisions.

Outlook and Recommendations

Decree 330 taking effect immediately upon its issuance is a signal that the regulator intends to commence active enforcement. For context, the Vietnam Competition Commission has recently been very active in enforcing consumer protection regulations against major companies, including privacy-related provisions such as requirements to obtain proper consent for the collection and use of personal data. With Decree 330 now in effect, the Ministry of Public Security (the authority responsible for data protection and cybersecurity) has full power to impose penalties for noncompliance with the Law on Personal Data Protection and the Law on Cybersecurity, notably including requirements relating to data protection impact assessments, cross-border data transfer impact assessments, data localization, data protection officers (DPOs) and forms and mechanisms for obtaining consent.

This is particularly significant given that businesses have had over three years to prepare—from the issuance of Decree No. 13/2023/NĐ-CP on personal data protection, which took effect on July 1, 2023, through to the enactment of the Law on Personal Data Protection effective January 1, 2026. Companies should reassess their compliance status and ensure they are prepared to demonstrate compliance when requested by the relevant authorities.

Artificial intelligence (AI), semiconductors, and digital assets are considered critical drivers of Vietnam’s future economic growth and are fundamental to the nation’s digital transformation targets. These sectors form the core of Vietnam’s strategy to build a robust, globally competitive digital economy. This strategic direction gained substantial momentum with the issuance of the Law on Digital Technology Industry (DTI Law) on June 14, 2025. The DTI Law was designed to attract investment, stimulate innovation, cultivate high-quality human resources, and ensure the responsible, secure, and sustainable growth of digital technologies like AI and digital assets, harmonizing Vietnam’s digital industry with international standards while safeguarding public interests and national security. Several key provisions of the DTI Law took effect on July 1, 2025, and the law will become fully effective on January 1, 2026. The government is delegated to provide further necessary guidelines and details for implementation of the law. Artificial Intelligence (AI): Principle-Driven and Risk-Based Regulations Under the DTI Law, there are seven core principles guiding the development, provision, and use of AI which are applicable to AI developers, providers and deployers. These principles favor values-based governance over purely technical prescriptions, and include the following: Taking a human-centered approach that upholds ethical values, inclusivity, flexibility, equality, and non-discrimination. Ensuring transparency, accountability, and explainability, with AI systems remaining under human control. Maintaining cybersecurity and system safety. Adherence to data protection and privacy regulations. Having the ability to control AI algorithms and models. Effective risk management throughout the entire lifecycle of AI systems. Compliance with consumer protection laws and other relevant legal frameworks. AI system management follows a risk-based approach, with the law categorizing systems into high-risk, high-impact, and other groups. High-risk AI systems are those that, in certain applications, may pose significant threats or harm to individuals or the public interest while

On August 19, 2025, the Trade Competition Commission of Thailand (TCCT) released its draft Guidelines on the Consideration of Unfair Trade Practices and Conduct Constituting Monopoly, Reducing Competition, or Restricting Competition in Multi-Sided Platform Businesses in the Category of Digital Platforms for the Sale of Goods or Services (E-commerce). A public comment period on the guidelines is open until September 18. The draft provides the first detailed framework for how the TCCT will interpret and enforce the substantive provisions under the Trade Competition Act against digital platforms, which have a unique network effect and require complex competition analysis. This development will profoundly impact the operations of e-commerce platforms, sellers, and associated service providers in Thailand. The guidelines primarily target e-commerce digital platform business operators, which are defined as follows: E-commerce digital platform: A medium facilitating the sale, purchase, or exchange of goods or services, including any operations to create transactions or interactions between business operators via an electronic transaction system, regardless of whether service fees are charged. E-commerce digital platform business operator: A service provider of a digital platform for the sale of goods or services who acts as an intermediary facilitating the sale of goods or services, including any operations to create transactions or interactions through an electronic transaction system by receiving orders for goods or services transacted via an electronic system, whether in the form of an e-marketplace, a social marketplace, or any other form that connects purchase orders for goods or services with business operators through an electronic system. Prohibited Conduct The guidelines classify potentially anticompetitive conduct and unfair trade practices into two categories: price-related and non-price-related conduct. 1. Price-related conduct The TCCT is targeting pricing strategies that can harm competition. Key prohibited behaviors include: Price below cost: Setting prices below the average total cost without

On August 18, 2025, Thailand’s Securities and Exchange Commission (SEC), in collaboration with the Ministry of Finance, the Anti-Money Laundering Office, and the Ministry of Tourism and Sports, announced the launch of TouristDigiPay. The initiative, implemented under the SEC’s Regulatory Sandbox, allows foreign tourists to convert digital assets into Thai baht for use in everyday transactions in Thailand. Foreign tourists who opt to participate in TouristDigiPay must open two accounts once they are in Thailand: An account with a licensed digital asset operator to sell or exchange digital assets for Thai baht; and A tourist wallet account with a licensed e-money operator regulated by the Bank of Thailand. Funds from digital asset sales will be transferred into the tourist wallet, enabling tourists to make payments at participating merchants that accept e-money. Key Regulatory Requirements The TouristDigiPay project will operate for a period of up to 18 months, with the following conditions: Only licensed digital asset brokers, dealers, and exchanges integrated with licensed e-money operators are eligible to participate. Operators must implement anti-money laundering (AML) protocols that are proportionate to the assessed risk level. These include: Conducting know-your-customer and customer-due-diligence (KYC/CDD) checks on all users. For monthly transactions exceeding THB 50,000 per person, verifying the source of the digital assets and assessing AML risk using internationally recognized blockchain forensic tools or equivalent procedures. Suspending or rejecting services if digital assets are transferred from wallets flagged for AML concerns. Ensuring that conversion between digital assets and fiat includes safeguards such as matching account names and returning digital assets only to the original wallet. The following transaction limits apply to participants in the TouristDigiPay initiative: Payments to small vendors are capped at THB 50,000 per month. Payments to vendors who have completed the know-your-merchant (KYM) process are capped at THB 500,000 per

More than a decade after the issuance of Decree No. 52/2013/ND-CP (as amended by Decree No. 85/2021/ND-CP; collectively, “Decree 52”), Vietnam’s legal framework for e-commerce is under growing pressure to keep pace with the evolving digital economy. While Decree 52 has provided a foundational framework, it has shown certain limitations in keeping up with issues such as counterfeit goods, intellectual property enforcement, unqualified products, and emerging models like livestream selling and affiliate marketing. To address these regulatory gaps, the Ministry of Industry and Trade (MOIT) has released the 2025 Draft E-Commerce Law (“Draft Law”) for public consultation. The Draft Law is intended to supersede the current framework under Decree 52 and establish a more detailed and comprehensive legal foundation for the regulations of e-commerce activities in Vietnam. It is currently expected to be submitted to the National Assembly for review and potential adoption during its 10th session in October 2025. In this article, we discuss the Draft Law’s most significant updates and legal developments in comparison to existing regulations, and assess the practical challenges that businesses may face in preparing for implementation in the near future. Platform Classification: Toward a More Nuanced Framework Unlike Decree 52’s simpler structure, which broadly categorized platforms into either (i) websites selling goods and services or (ii) websites providing e-commerce services, the Draft Law introduces a more detailed framework that aims to classify platforms based on their technical functions and business models. Specifically, the Draft Law introduces a four-tier classification system for e-commerce platforms, consisting of: (i) Direct Business Platforms, (ii) Intermediary Platforms, (iii) Social Networks with E-Commerce Functions, and (iv) Multi-Service Integrated Platforms. This approach reflects an effort to more accurately capture the complexity of today’s e-commerce landscape, including hybrid platforms such as TikTok Shop. While this approach reflects the growing complexity of
