On 19 August 2026, the Government issued Decree No. 330/2026/ND-CP providing for administrative penalties for violations in the fields of cybersecurity and personal data protection (“Decree 330”), which takes effect from 19 August 2026.
Decree 330 was issued to establish a specific penalty mechanism for violations in the field of personal data protection, thereby strengthening the enforcement and deterrent effect of the regulations on personal data protection. This is an important step in further developing the legal framework in the context where regulations on personal data protection have been progressively developed and applied since 2023, but prior to the issuance of Decree 330, there had been no comprehensive and specific administrative penalty mechanism for each group of violations in this field. Some notable points of Decree 330 include:
Violations of regulations on consent of personal data subjects
To strengthen compliance with the requirement to obtain consent from data subjects before processing their personal data, Decree 330 provides for fines applicable to violations of the consent requirements under two principal penalty brackets:
A fine ranging from VND 30 million to VND 50 million applies to acts such as processing data without consent; setting consent as the default option or providing misleading instructions; making service provision conditional upon consent; failing to separately distinguish each processing purpose; obtaining consent without maintaining logs; or failing to provide notification when processing sensitive personal data.
A higher fine ranging from VND 50 million to VND 70 million applies to intentional acts of continuing to process personal data after the data subject has withdrawn their consent or upon a request from a competent State authority, as well as the act of treating a user’s silence as consent without authorization.
In addition to monetary fines, violating organizations and enterprises may also be subject to additional penalties and stringent remedial measures. The competent authorities may confiscate all material evidence and administrative violation instruments used to commit the violation. At the same time, the violating party may be required to destroy or permanently delete all personal data that has been unlawfully collected and processed in a manner that renders such data irretrievable, and to remit all unlawful proceeds or profits to the State budget.
Accordingly, enterprises should pay attention to default options on forms, clearly separate each processing purpose for which consent is sought, and implement management systems capable of evidencing consent in the event of inspection or examination. Upon receiving a request from a user to withdraw consent, enterprises should have procedures in place to automatically update their systems and immediately cease processing the relevant personal data in order to avoid the risk of penalties and being required to destroy the entire accumulated database.
Violations of regulations on personal data processing impact assessments
To strengthen oversight and ensure compliance during data processing activities, Decree 330 introduces specific sanctions for violations of regulations on personal data processing impact assessments.
Specifically, violations of the obligations to prepare, maintain, submit and update the relevant dossiers are subject to fines ranging from VND 20 million to VND 30 million. This penalty bracket applies to cases where an enterprise commences personal data processing activities but fails to prepare or maintain a Personal Data Processing Impact Assessment Dossier at its headquarters; fails to submit one original copy of the dossier to the Department of Cyber Security and High-Tech Crime Prevention under the Ministry of Public Security within 60 days from the date on which personal data processing is first conducted; intentionally fails to complete the dossier as requested by the competent specialized authority; fails to update the dossier every six months when there are changes; or fails to update the dossier within 10 days in cases where an update is required by law.
In particular, a fine ranging from VND 50 million to VND 100 million applies to intentional acts involving falsification or non-cooperation, including: deliberately falsifying data or providing inaccurate information in the Personal Data Processing Impact Assessment Dossier, or refusing to amend or complete the dossier upon receipt of a written request for remediation from the Department of Cyber Security and High-Tech Crime Prevention.
In addition to monetary fines, violating enterprises may also be subject to stringent remedial measures. Accordingly, the violating organization may be required to prepare, complete and submit the dossier in accordance with the applicable regulations and provide evidence of compliance to the competent authority. Notably, where an enterprise fails to prepare or maintain the dossier at its headquarters, it may be required to suspend all personal data processing activities until it has fully discharged its dossier submission obligations and obtained official confirmation from the specialized personal data protection authority.
Accordingly, enterprises should proactively review all internal personal data processing procedures, prepare and maintain the relevant impact assessment dossier at their headquarters, and ensure that the original dossier is submitted to the Department of Cyber Security and High-Tech Crime Prevention within 60 days from the commencement of personal data processing. In addition, establishing a six-monthly review mechanism and a procedure for updating the dossier within 10 days following a change are mandatory steps to mitigate the risk of administrative penalties and, in particular, the risk of being required to suspend all personal data processing activities.
Violations of regulations on cross-border transfer of personal data
To strengthen control over the transfer of personal data outside the territory of Vietnam, Decree 330 introduces stringent sanctions for violations of regulations on cross-border transfers of personal data.
Specifically, a fine ranging from VND 30 million to VND 50 million applies to acts including: failure to prepare or submit the cross-border data transfer impact assessment dossier within 60 days from the date of the first transfer, failure to complete or update the dossier as required, failure to maintain the dossier readily available for inspection, failure to notify the contact details of the representative of the data recipient, or failure to establish control mechanisms resulting in the data being processed beyond the declared scope.
In particular, a fine ranging from VND 50 million to VND 100 million applies to cases involving failure to enter into a contract or data transfer document establishing binding responsibilities; failure to obtain consent from the data subject or notify the data subject of the transfer of their data overseas; failure to apply appropriate security measures; obstruction of an inspection; continuing to transfer data after being ordered to cease by a competent authority; or failure to report and cooperate in preventing or mitigating damage when a data breach or data loss occurs at the recipient’s end.
Notably, Decree 330 establishes a fine calculated as a percentage of the total revenue generated in the Vietnamese market during the immediately preceding financial year for serious violations, such as failure to prepare the relevant dossier, concealment of data flows, or inaccurate declaration of data flows resulting in the disclosure or loss of Vietnamese citizens’ personal data. The applicable fine ranges from 1% to 2% of revenue for incidents affecting between 10,000 and fewer than 100,000 data subjects; from 2% to 3% of revenue for incidents affecting between 100,000 and fewer than 1,000,000 data subjects; and up to 3% to 5% of revenue where 1,000,000 or more data subjects are affected or national defense or security is threatened. Where the violating organization has no revenue in Vietnam or the fine calculated based on the percentage of revenue is lower than VND 3 billion, fixed fines will apply depending on the scale of the violation, ranging from VND 200 million to VND 500 million, from VND 500 million to VND 1 billion, and from VND 1 billion to VND 3 billion, respectively.
Accordingly, enterprises should review all cross-border personal data transfer activities, prepare and submit the Cross-Border Personal Data Transfer Impact Assessment Dossier using the prescribed form, and ensure timely submission. In addition, reviewing and entering into data transfer agreements containing provisions imposing confidentiality and other responsibilities on the recipient, updating transparent consent mechanisms for data subjects, and establishing procedures for responding to data disclosure or loss incidents occurring at the recipient’s end are mandatory steps to mitigate the risk of fines of up to 5% of revenue or suspension of cross-border data transfer activities.
Violations of regulations on the appointment of personal data protection officer, units
To ensure effective implementation of internal data governance, Decree 330 establishes a legal framework for imposing penalties on violations relating to the appointment of personnel and establishment of personal data protection units.
Specifically, a warning or fine ranging from VND 10 million to VND 20 million applies to acts of failing to enter into confidentiality responsibility agreements with personnel responsible for personal data protection; failing to organize training or professional development; or failing to specify the functions, duties and powers in the appointment document or decision establishing the relevant unit.
In particular, a fine ranging from VND 20 million to VND 30 million applies to more serious violations, including failure to issue a formal document appointing responsible personnel or a decision establishing the relevant unit; appointing personnel who have not received specialized training; or appointing a person who does not satisfy the applicable requirements (i.e., holding at least a college-level qualification or having at least two years of experience in legal affairs, IT, cybersecurity, data security, risk management, compliance control or human resources management).
In addition, violating enterprises may be subject to remedial measures requiring them to issue the necessary appointment documents and regulations specifying the relevant duties, or to replace the responsible personnel with another person who satisfies the applicable legal requirements and submit evidence of such compliance to the competent authority.
A common violation is for enterprises to formally appoint personnel or establish a personal data protection unit without clearly defining its responsibilities, entering into confidentiality agreements, or providing appropriate training. In the event of an inspection, such formalistic appointments may result in penalties and require the enterprise to dismiss the appointed personnel and identify suitable replacements.
Accordingly, enterprises should proactively review all documents relating to the appointment of personnel and establishment of personal data protection units. Issuing a formal decision specifying the functions and duties of the relevant personnel/unit, entering into a separate confidentiality agreement, reviewing the personnel’s qualifications and experience, and proactively organizing professional training and development programs for responsible personnel are mandatory legal steps to prevent the risk of administrative penalties and disruption to internal operations.
Violations of regulations on personal data protection in recruitment and labor management
Under the 2025 Law on Personal Data Protection, enterprises may only require job applicants to provide information that is directly relevant to the recruitment purpose and are required to delete and destroy the personal data of applicants who are not recruited, unless otherwise agreed.
Consistent with this requirement, Decree 330 introduces a detailed penalty framework for violations involving personal data in recruitment and labor management. Specifically, a fine ranging from VND 20 million to VND 50 million may apply to acts of requiring job applicants to provide data that is not relevant to the recruitment purpose, using application data for another purpose without an agreement, processing data beyond the scope of consent, or failing to delete or destroy the data of unsuccessful applicants.
For employees during the employment relationship, the fine increases to between VND 50 million and VND 70 million where an enterprise retains employees’ personal data beyond the statutory or agreed retention period, fails to delete the data upon termination of the employment contract, or unilaterally applies technological measures to monitor or collect data in the workplace, such as installing cameras or device-monitoring software, without providing clear notice to employees. In particular, the act of processing or using data unlawfully collected through technological or technical measures is subject to a fine ranging from VND 70 million to VND 100 million.
In addition to monetary fines, enterprises may be required to permanently destroy or delete all personal data unlawfully collected and remit any unlawful proceeds arising from the violation. Accordingly, automatically retaining applicant records indefinitely or conducting employee monitoring in a non-transparent manner may expose enterprises to significant legal risks.
Accordingly, enterprises should proactively review their internal recruitment and human resources management procedures to ensure legal compliance. During recruitment, the recruitment function should collect only information that is genuinely necessary for the relevant position and establish an agreement allowing the retention of application records for unsuccessful applicants, rather than automatically retaining such records by default. For existing employees, enterprises should issue clear notices or internal regulations governing the use of workplace monitoring technologies, such as cameras and device-monitoring software, and specify the applicable data retention periods and procedures for deleting and destroying personal data upon termination of employment.
Violations involving the unlawful purchase, sale or transfer of personal data
Decree 330 establishes a penalty mechanism based on the amount of unlawful proceeds obtained by organizations engaging in the unlawful purchase or sale of personal data.
Accordingly, a violating organization may be subject to a fine ranging from two to ten times the amount of proceeds obtained from the unlawful purchase or sale of personal data. This means that, if an enterprise unlawfully earns VND 1 billion from secretly selling a customer information list, the fine imposed on that enterprise could be as high as VND 10 billion.
Where the amount of unlawful proceeds cannot be determined, fixed fines ranging from VND 500 million to VND 1 billion apply to unlawful transactions involving basic personal data of 10,000 or more individuals or sensitive personal data of 2,000 or more individuals. A fine ranging from VND 1 billion to VND 3 billion applies to unlawful purchase or sale of personal data that seriously infringes upon core areas such as national defense, national security, social order and safety, foreign affairs or the macroeconomy, or directly threatens the life, health, honor, dignity, property, or lawful rights and interests of other organizations or individuals.
Decree 330 has expanded the regulatory scope to cover most forms of exploitation and trading of information currently occurring in the market. Specifically, providing, sharing or exchanging personal data for material benefit or any other benefit in violation of the law is considered a violation.
In addition, transferring personal data for a fee without a lawful agreement or consent from the data subject, or entering into a data transfer agreement without clearly specifying the purpose or processing the data for a purpose different from the original purpose, is also classified as unlawful purchase or sale of personal data.
Accordingly, enterprises should urgently review all existing activities involving the sharing, exchange or commercialization of customer or partner databases. All data transactions generating revenue or commercial benefits must be based on the user’s clear consent and must apply data de-identification techniques when the data is placed on data trading platforms.
Compliance recommendations
In the context where violations may result in various levels of penalties, and the aggregate amount of fines may become significant if an enterprise simultaneously violates multiple obligations, the enterprise should proactively review and strengthen its compliance system through the following steps:
- Determine the scope of application, processing roles and exemptions
Clearly determine whether the enterprise acts as the Data Controller, Data Processor or Third Party for each processing activity; and review cases eligible for exemption from or reduction of obligations, particularly exemptions applicable to small enterprises and cases exempt from preparing a cross-border data transfer impact assessment dossier.
- Establish a data map and legal basis map
Prepare a data map to fully identify personal data flows throughout the entire processing lifecycle, including collection, use, storage, sharing and transfer of data. On this basis, determine the corresponding legal basis for each processing activity, such as consent, performance of a contract, compliance with a legal obligation, or other legal bases as prescribed by law.
- Review the consent mechanism and procedures for exercising data subject rights
Remove “pre-ticked box” mechanisms or any default assumption that silence constitutes consent. The enterprise should establish a comprehensive tracking table for the deadlines applicable to requests to exercise data subject rights, including cases where such requests are made through a Data Processor or Third Party, the applicable processing period and any extension period. At the same time, the enterprise should maintain complete logs and evidence demonstrating the collection of consent.
- Establish a personal data incident-response playbook
Develop a standardized procedure covering the process from detection, recording and classification of incidents to harm assessment, reporting/escalation mechanisms and fulfilment of notification obligations within the statutory time limits. In particular, the enterprise should establish mechanisms for controlling and handling incidents within 72 hours to mitigate the risk of penalties.
- Complete the DPIA and cross-border data transfer assessment dossier (CTIA)
Review, complete and maintain the Personal Data Processing Impact Assessment Dossier (DPIA) and the Cross-Border Personal Data Transfer Impact Assessment Dossier (CTIA) in accordance with the forms and requirements under Decree No. 356/2025, while establishing a mechanism for updating the dossiers when there are changes to processing activities, systems, data recipients or other relevant factors.
- Review the DPO, DPA and vendor governance mechanism
Ensure that the DPO/personnel responsible for personal data protection fully satisfies the applicable criteria, avoiding merely formal appointments. At the same time, review the Data Processing Agreements (DPAs) and vendor governance mechanisms to ensure that the responsibilities, rights and obligations of the parties in relation to personal data protection are clearly allocated and consistent with the requirements of Decree No. 356/2025.
