DNA: Data Protection and Cybersecurity Regulation in Southeast Asia

Tilleke & Gibbins has contributed the Cambodia, Myanmar, Thailand, and Vietnam chapters to Data Protection and Cybersecurity Regulation in Southeast Asia, a wide-ranging guide published by Drew Network Asia (DNA). The resource provides a comprehensive overview of data protection and cybersecurity laws across the region, offering practical insight into compliance requirements and regulatory developments affecting organizations that handle personal data or operate digital services in Southeast Asia.

The guide begins with a regional overview, including the broader ASEAN context and cooperation initiatives. Jurisdiction-specific chapters follow a consistent structure—covering data privacy and governance obligations, security requirements and breach notification, outsourcing and cross-border data transfers, and broader accountability and compliance measures. This format allows readers to compare regulatory approaches across markets such as Brunei, Indonesia, Malaysia, the Philippines, Singapore, and others.

In addition to the country chapters, the publication addresses cybersecurity and privacy engineering challenges, providing guidance for organizations and outlining obligations applicable to data controllers, processors, and intermediaries. A dedicated section on data breach management across ASEAN examines notification requirements, response considerations, and practical steps for managing incidents in a regional or global context.

The guide is intended to serve as a practical reference, and the authors note that specific legal requirements may vary depending on sector, processing activity, or evolving legislation. Readers seeking more detailed advice can contact the practitioners listed in each chapter.

Vietnam’s Decree No. 163/2024/ND-CP (Decree 163), which has been in full effect since January 1, 2025, provides crucial guidance on the implementation of Vietnam’s 2023 Telecom Law. Decree 163 replaced Decree No. 25/2011/ND-CP dated April 6, 2011 (Decree 25), which guided the implementation of the previous 2009 Telecom Law, and introduces many notable changes to the regulations on telecom service provision. Some key changes that will impact businesses engaged in the telecom sector in Vietnam are detailed below. 1. Classification of Telecom Services The classification of telecom services into “basic telecom services” and “value-added telecom services” has been retained, in alignment with Vietnam’s WTO commitments in the telecom sector. However, Decree 163 expands the scope of both categories, as follows: Basic telecom services: “Transmission services for machine-to-machine (M2M) communication” and “leasing services of all or part of the telecom network” are added. “Image transmission services” is changed to “transmission services for radio and television.” Value-added telecom services: “Data center services,” “cloud computing services,” and “basic telecom services over the internet” (also known as over-the-top (OTT) telecom services) are added. 2. M2M Communication Services Since M2M communication services are classified as basic telecom services, without exception, they are subject to the same regulatory framework. Specifically: Cross-border provision: M2M communication services provided across borders must be conducted through a commercial agreement with a Vietnamese telecom enterprise licensed to provide telecom services with an international communication scope. Onshore provision: Onshore M2M communication services will require a telecom license. 3. New Telecom Services (Data Center, Cloud, and OTT Telecom Services) The 2023 Telecom Law adopted a light-touch management approach for data center, cloud, and OTT telecom services by not requiring the same licensing as previously regulated value-added telecom services, but instead mandating registration or notification before service provision. Decree 163 offers clearer guidance

Vietnam’s Decree No. 147/2024/ND-CP on the management, provision, and use of internet services and online information (Decree 147) was issued on November 9, 2024, and came into effect on December 25, 2024. Decree 147 represents a more stringently regulated digital landscape in Vietnam, creating challenges not only for offshore service providers offering cross-border services but also for onshore providers. As these new regulations impose stricter requirements, particularly in areas like content control, user authentication, data storage, and service license/notification, companies will need to adapt quickly to maintain compliance and minimize legal risks. The following are some of the key topics covered by Decree 147. [Note: Shortly after the issuance of Decree 147, Vietnam began a government restructuring process, with the aim of streamlining the government by consolidating and eliminating various ministries and agencies. Thus, the decree’s references to authorities such as the Authority of Broadcasting and Electronic Information (ABEI) and the Ministry of Information and Communications (MIC) are subject to change.] 1. Cross-Border Information Provision Cross-border information provision is defined broadly as the provision by overseas organizations and individuals of information and online information content services for service users in Vietnam to access or use. This wide-ranging definition encompasses various types of cross-border services, including social network services, online game services, and app store services. However, cross-border provision of online game services remains prohibited under Decree 147 (see further details below). Offshore providers of services on a cross-border basis who lease data storage in Vietnam or meet a threshold of 100,000 or more total visits per month from Vietnam for six consecutive months (“regulated cross-border providers”) must adhere to stricter requirements. Specifically, they are required to, among other requirements: Notify the relevant authority of their contact information, including the location of the main server providing the service, within 60
