Cloud computing services typically do not require a telecommunications license. However, when such services utilise a leased line network to connect users to the cloud infrastructure, they are categorised as telecommunications services. Consequently, providers must obtain a Type 1 license, as prescribed by the National Broadcasting and Telecommunications Commission (NBTC) under the Telecommunications Business Act. This requirement is outlined in Agenda 4.24 of the National Telecommunications Commission (NTC) meeting No. 38/2013.

As a result, conflicts of interest linked to personal incentives continue to be an issue.

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 Computer-Related Crime Act and the Notification of the Ministry of Digital Economy and Society (MDES) establish a safe harbour regime for intermediaries beyond copyright infringement. According to Section 15 of the Computer-Related Crime Act, service providers are not liable of for for the content published if they remove computer data once it has received a notification from the Minister of Digital Economy and Society (MDES) to discontinue the dissemination of these. In addition, the Notification includes the 'Notice and Take Down' procedure to remove the offence's content and the intermediary's liability. This notification allows an individual to submit their notices of online offence to the police or competent officers. After the service provider receives the notification from the Ministry, the competent officer, or court order, they must remove or stop the dissemination of certain content immediately within the given period.

This request includes keeping a 'log file' of customers' computer traffic data, including their IP address, full name, ID card number, or passport details. As defined in Art. 3 of the CCA, "Computer Traffic Data", encompasses information related to the communication of a computer system, such as the origin, source, terminal, route, time, date, size, duration, type of service, and other relevant communication details.
