In October 2020, the Ministry of Digital Economy and Society (MDES) issued an order requiring internet service providers (ISPs) and mobile service providers to block four internet protocol (IP) addresses associated with Telegram, a messaging app widely used by protesters. Although the government has not publicly disclosed the total number of URLs blocked through court orders, the MDES reported that during the first nine months of 2022, it obtained court orders to block approximately 4,735 URLs, including 1,816 URLs containing allegedly offensive content about the monarchy.
Websites have also been blocked on grounds of national security, for gambling content, for alleged violations of intellectual property rights, and for hosting unauthorised virtual private network (VPN) services. In addition to blocking and filtering, content removal reportedly continues under tight government control.

The appointment of a Data Protection Officer (DPO) is a mandatory condition under the Personal Data Protection Act (PDPA). Section 41 of the Act specifies that the data controller and data processor shall designate a DPO in the following circumstances: the activities such as collection, use, or disclosure of personal data.

Also, in Section 66, the CSSC has the power to carry out or order competent officials to carry out operations, only to the extent necessary for preventing cyber threats, in the following matters:
- to enter a place for inspection upon written notification;
- to gain access, copying or filtering computer data, computer systems or other related data;

Section 6 of the Act provides the National Intelligence Agency with the power to order public agencies or any person to submit the information or document that impacts national security within the specified period.

Certain activities can be done without filing a motion to the court and are deemed in good faith for the public or national security.

The Copyright Act establishes a safe harbour regime for intermediaries for copyright infringements. Although Thailand has not signed the WIPO Copyright Treaty, in 2015, two copyright amendment laws were approved: the Copyright Act (No. 2) and Copyright Act (No. 3). These two laws implemented many of the key provisions of the WIPO Copyright Treaty. Copyright “safe harbour” protection for intermediaries such as cloud service providers is contained in the 2015 amendments to copyright laws. The provisions exempt Internet intermediaries from liability in broad circumstances provided that they did not control, initiate, or order the infringement. The intermediary is shielded from liability for content until they receive a court order ordering them to remove it.

The Foreign Business Act (FBA) 1999 governs foreign investment in Thailand.

According to Section 8 of the Telecommunications Business Act 2001, Type 2 licenses (telecommunications operators providing services to a specific group of customers, with or without operating their own telecommunications network) and Type 3 licenses (telecommunications operators providing their own telecommunications network for public use) cannot be granted to foreign applicants. As a result, foreign ownership in these sectors is capped at 49%.

The majority of the telecommunications infrastructure, such as the national broadband network and most submarine cable landing stations, is owned by the Government through state-owned enterprises (SOEs). The main SOEs in the telecommunications sector are TOT Public Company Limited and CAT Telecom Public Company Limited.

Thailand does not mandate functional separation for operators with significant market power (SMP) in the telecom market. However, accounting separation is mandated.

Thailand has appended the World Trade Organization (WTO) Telecom Reference Paper to its schedule of commitments.

According to the Act on the Organisation to Assign Radio Frequency and to Regulate the Broadcasting and Telecommunications Services B.E. 2553, the executive authority for the supervision and administration of services in the telecommunications sector in Thailand is the National Broadcasting and Telecommunications Commission. It is reported that the National Broadcasting and Telecommunications Commission is independent from the government in the decision-making process.

Additionally, Clauses 7 and 8 of the "Notification of the Personal Data Protection Committee on Criteria for the Protection of Personal Data Sent or Transferred to a Foreign Country Pursuant to Section 29 of the Personal Data Protection Act" outline additional requirements related to binding corporate rules, standard contractual clauses, and certifications, among others.
