Security services are considered a critical profession that has been part of Thai society for a long time. Due to changes in social conditions, private organizations have taken on roles in maintaining security and protecting assets for businesses, companies, stores, and even government agencies. Additionally, the increasing rate of crime and fraudulent activities, along with the development of new forms of crime, further underscores the importance of security services. Currently, the security services business in Thailand faces intense market competition, driven by the growing demand from both government and private sector clients. The industry is worth billions of baht and has a large workforce turnover, with hundreds of thousands of people employed in the sector. Furthermore, there are high expectations regarding the quality of service provided by security personnel tasked with ensuring public safety.
