Personal Data Protection and Cybersecurity Laws to Encourage Thailand’s Digital Transformation

After approximately a decade drafting general personal data protection laws and formulating a regime to protect personal data and privacy rights, Thailand finally issued the country’s first unified personal data protection legislation in 2019.

The public was surprised when the draft Personal Data Protection Act (PDPA) was published for the final round of hearings. The draft PDPA largely adopted the preeminent personal data protection standards as expressed in the European Union’s General Data Protection Regulation (GDPR). The government expressed its objective to enhance personal data protection standards in Thailand to meet international standards, which would permit cross border transfers of personal data to Thailand, without any material limitations.

The PDPA, which was finally published in the Government Gazette in May 2019, also established a new independent regulator, the Personal Data Protection Commission (PDPC), tasked with enforcing the PDPA. All members of the commission must possess the qualifications required by the PDPA.

The PDPA was enacted with a grace period of one year for the requirements relating to the processing of personal data—which would provide businesses with sufficient time to adjust their practices to ensure compliance with the new requirements. It is a significant undertaking for businesses to adjust from having no general law on data protection to being required to meet high international data protection standards comparable to those in the GDPR.

GPDR concepts that were incorporated into the PDPA include (1) purpose limitation, (2) transparency, (3) lawfulness and fairness, and (4) data minimization. When collecting personal data, data controllers are required to establish a lawful basis to allow for such collection and processing of personal data. The lawful bases for general personal data are also similar to those under the GDPR, with concepts such as contractual necessity, legal obligation, legitimate interest, vital interest, and consent. Special types of personal data, such as health data and biometric data, will be subject to more stringent requirements under the PDPA. Data breach notification requirements are also imposed by the PDPA, and this is one of the obligations that data controllers are expected to meet.

The PDPA also recognizes the concept of extraterritorial effect, which is not common in Thailand. This raises the possibility that overseas data controllers could also be subject to the PDPA’s requirements in respect to their processing activities involving the personal data of data subjects in Thailand. Certain types of overseas data controllers and data processors are also required to appoint a local representative in Thailand without any limitation of liability in respect to the conduct of the overseas data controller or data processor.

In early May 2020, shortly before the PDPA grace period was scheduled to conclude, Thailand found itself embroiled in the global COVID-19 pandemic. Similar to what transpired in Brazil, the Thai government, led by the Ministry of Digital Economy and Society (MDES), decided to postpone the PDPA by issuing a royal decree. In essence, the decree meant that full implementation of the PDPA was further postponed to June 1, 2021, for almost all types of businesses (subject to the details specified in the royal decree).

To prepare for full enforcement of the PDPA, businesses should start the process of attaining a full understanding of the requirements of the PDPA if they haven’t already (see the unofficial English translation of the PDPA). The PDPA includes a number of principles that businesses can prepare to address, but the law does not fully detail or clarify all of the tasks that data controllers and data processors need to undertake in order to ensure full compliance with the PDPA, as the relevant clarifications will be issued in the form of supplemental regulations, notifications, or guidelines during the upcoming 12 months.

Due to the long delay in the PDPC’s selection process, the official appointment process for the PDPC only recently reached its final stage. This may impact the timeline for implementing supplemental regulations, without which businesses may be unsure about whether they need to appoint a DPO, how to establish incident management procedures to detect and report data breaches, and how to respond when data subjects make a request in accordance with their rights. Nevertheless, the Office of PDPC has announced its plan to hold public hearings on the first set of the sub-regulations on February 15–18.

Preparation of Industry Guidelines

While awaiting further developments relating to the PDPA and its supplemental regulations, certain business associations and industry groups are currently in the process of preparing their specific guidelines to ensure compliance with the PDPA, as well as collaborating with industry regulators such as the Bank of Thailand and the Office of Insurance Commission. A key concern for these organizations is the sharing of health data, which is subject to more stringent requirements than general personal data. Under the GDPR, it may be possible to rely on substantial public interest conditions for collecting and processing health data for insurance purposes, without the need to obtain explicit consent from the data subject (i.e., the insured). The PDPA, on the other hand, may not provide exemptions for businesses in the insurance industry or other related industries in regard to the processing of health data for insurance purposes. It is therefore imperative for industry regulators and associations to be actively involved in the development of the PDPA’s supplemental regulations and industry guidelines, so that the needs of the businesses are fully factored in when assessing the requirements to be included in these regulations.

How exactly the PDPA will develop remains to be seen, but it is anticipated that Thailand will look to and rely on personal data protection requirements set out under international standards—particularly those encompassed under the GDPR and personal data protection laws adopted in other countries—and use those principles to formulate and shape its own specific guidelines in the future.

Cybersecurity Act

Passed around the same time as the PDPA, the Cybersecurity Act B.E. 2562 (2019) also plays an important role in the ongoing digital transformation of Thai society. Upon the law’s enactment, there were no subordinate regulations stipulating specific requirements and obligations, especially in relation to the law’s provisions on prevention, protection, and management of cyber risks for government agencies or private organizations providing critical information infrastructure services, or “CII organizations.”

The National Cyber Security Commission recently issued a draft master plan and subordinate regulations for public hearing. These five draft regulations consist of (1) policies and plans on the cybersecurity, (2) a cybersecurity action, (3) management policies in connection with cybersecurity for state agencies and CII organizations, (4) a code of practice for the cybersecurity, and (5) a standard framework for cybersecurity.

Of these, items 3 through 5 have significant implications for state agencies and CII organizations, comparing to the first two draft regulations. The draft management policies in connection with cybersecurity for state agencies and CII organizations indicate that state agencies and CII organizations will have to observe principles of governance, risk, and compliance; prescribe the authority, role, and responsibility of their personnel; implement three lines of defense management; and provide a risk management plan with policies, standards, and guidelines.

Additionally, the draft code of practice for cybersecurity requires state agencies and CII organizations to have a cybersecurity verification procedure, cybersecurity risk assessment, and cybersecurity threat response plan.

Lastly, the draft standard framework for the cybersecurity sets out  guidelines covering (1) cybersecurity risk identification and assessment, (2) cybersecurity risk protection measures, (3) cybersecurity threat verification and monitoring measures, (4) follow-up measures for after a cybersecurity threat is detected, and (5) sustainability and restoration measures relating to cybersecurity threats.

The development of these cybersecurity provisions is still at an early stage and will require further approval from the relevant authorities. However, it is anticipated that Thailand will look to and rely on the principles of the U.S. National Institute of Standards and Technology cybersecurity framework in order to set out internationally accepted guidelines and establish cybersecurity standards in Thailand.

Digital Transformation in Thailand

As access to and adoption of new technologies continues to expand at a rapid pace in Thailand, the PDPA and Cybersecurity Act provide important structure to guide businesses, regulators, and individuals in these technological developments. Moreover, these legal frameworks set a solid basis for sustainable, standards-based growth that responds to the unique needs and challenges of today’s technological landscape. While certain aspects of the laws’ implementation are still being clarified, both pieces of legislation have an important role in both the short- and long-term success of Thailand’s technological advancement.

Vietnam has progressively positioned blockchain as a strategic technology within its broader digital transformation agenda over the past decade. From early policy orientations to more recent legislative developments, the regulatory approach has gradually shifted from high-level recognition to more concrete legal integration. Against this backdrop, a new draft decree regulating activities relating to product and goods identification, authentication, and traceability (the “Draft Decree”) marks a notable turning point. Rather than merely referencing blockchain as a policy priority, the Draft Decree incorporates blockchain directly into a nationwide regulatory system, positioning it as part of the underlying infrastructure for data governance and public administration in relation to the management, verification, and traceability of product-related data. Evolution of Vietnam’s Blockchain Legal Framework: The Draft Decree in Context Vietnam’s blockchain legal framework has developed in several distinct phases. The first phase, beginning around 2019, was characterized by high-level policy recognition in several resolutions of the Party Central Committee. Particularly, blockchain was identified as part of the broader category of digital technologies critical to industrial modernization and participation in the Fourth Industrial Revolution. These resolutions did not regulate blockchain directly, but established its strategic importance at the national level. The second phase (2023 to 2025) saw the introduction of national strategies and technology policies that more explicitly recognized blockchain as a priority technology. Those policies collectively signaled a clear policy commitment to developing blockchain infrastructure and applications. However, these instruments remained largely at a policy-level and did not establish binding regulatory frameworks. The third phase (from 2025) involves the gradual integration of blockchain into sectoral legislation. Laws such as the Law on Digital Technology Industry (2025), the Law on Personal Data Protection (2025), and the Law on Science, Technology, and Innovation (2025) have introduced concepts such as digital assets, crypto assets, and even specific

Thailand’s Personal Data Protection Committee (PDPC) has launched a public consultation period on a draft notification setting out criteria for data subject access requests (DSARs). The draft notification addresses practical uncertainties in handling DSARs by introducing standardized procedural requirements for data controllers. The consultation period runs from April 16 to May 15, 2026. The notification will enter into force 30 days from the date of its publication in the Government Gazette. Key Features of the Draft Notification The draft notification covers the following key areas: Scope of information subject to access. Data controllers must enable data subjects to access at least the following upon request: (1) personal data collected directly from them; (2) personal data obtained from other sources; and (3) the source of personal data obtained from other sources without consent. Information required under section 23 of the PDPA and information that must be recorded pursuant to section 39 of the PDPA—such as the categories of personal data collected and purposes of processing—must also be made available. Submission channels and formal requirements. Data controllers must provide at least in-person and postal channels for DSARs, while electronic or other channels are optional. Requests may be made either directly by the data subject or through an authorized representative, and must be signed and include sufficient identifying information, a preferred response method, and DSAR details. Identity verification documents (and proof of authority if the request is through a representative) are required, and additional documentation may be requested for verification or communication purposes. Data controllers may use different verification methods for DSARs submitted via electronic or other channels, provided this does not create undue obstacles to the exercise of data subject rights. Verification and response timelines. Data controllers must complete preliminary verification within seven business days of receiving a request. If a

Thailand has introduced new regulatory guidance requiring digital platform operators to adopt structured, transparent, and fair fee practices. On March 16, 2026, the Electronic Transactions Development Agency (ETDA) published Announcement No. DPS 2/2569, titled “Guidelines for Transparency and Fairness in Digital Platform Service Fee Determination,” issued under the Royal Decree on Digital Platform Service Business Operations B.E. 2565 (2022). The guidelines establish a framework governing how digital platform operators should set, disclose, and adjust fees charged to users and related service providers such as logistics and payment providers. Although framed as best-practice guidance rather than legally binding rules with explicit penalties, the guidelines carry regulatory weight under the royal decree and represent a significant step toward structured governance of digital platform fee practices in Thailand. The guidelines establish various transparency principles and divide fees into two distinct categories—compulsory and additional—with specific governance principles for each. Transparency Principles The guidelines recommend that digital platform operators adopt several transparency measures to ensure that users can fully understand the costs of using a platform. Fee catalog. All fees should be consolidated into a single, accessible location, which should include the fee name, definition, scope of covered services, calculation methodology, rate, billing period, and calculation examples. Minimum service disclosure. Operators should disclose the minimum service that users can expect, such as baseline visibility, product listing capabilities, access to transaction data, and back-end dashboard access. Price structure disclosure. Operators should disclose the categories of costs underlying their fees, such as system maintenance, cybersecurity, and operational costs. While exact cost figures need not be made public, operators should be able to provide numerical data to regulators upon request. Clear fee formulas. Fee calculations should be simple and easy to understand—for example, percentage of net sales, cost per order, or cost per product listing. Operators should

As digital commerce continues to reshape consumer behavior in Thailand, the Office of the Consumer Protection Board (OCPB) has been taking steps to review and update key regulations for online platforms. The OCPB has had a particular focus on addressing the risks posed by e-marketplace businesses—from misleading product information to fraudulent online transactions. Some of the regulator’s current legislative efforts related to Thailand’s labeling regulations as well as potential changes to the country’s law on direct sales and marketing. Proposed Changes to Consumer Protection Labeling Regulations On February 24, 2026, the OCPB convened a public hearing to review the Notification of the Committee on Labels re: Specification of Goods as Controlled Label Goods B.E. 2565 (2022) and its annex issued under the Consumer Protection Act. The closed-door session, which started the OPCD’s process of seeking feedback on the proposed changes, brought together representatives from government agencies, business operators, and consumer groups. The OCPB explained that its review of the labeling regulations aims to address regulatory gaps arising from evolving commercial practices, particularly the expansion of e-commerce and cross-border transactions. Authorities highlighted recurring issues involving product information that is unclear, incomplete, or potentially misleading in digital sales channels. The proposed revisions are intended to improve consumers’ access to accurate and complete product information, ensure that label disclosures remain relevant amid the growth of e-commerce, and strengthen protections against deceptive or misleading digital advertising. The review is being undertaken pursuant to the Consumer Protection Act B.E. 2522 (1979). As part of the initiative, the OCPB signaled a potential update to the categories of “controlled label products” as well as enhanced disclosure obligations for business operators, with the broader aim of promoting greater transparency, reinforcing operator accountability, and aligning Thailand’s labeling framework with current market conditions. The OCPB secretary general emphasized that
