This paper explores the potential contribution of private security to enhancing the safety of sex workers serving foreign clients in the cultural context of South Korea. The role of private security continues to increase in today's security governance with the growing need for safety-related services and advancing information and communications technology. Due to limited resources in the public sector and the illicit nature of their profession, sex workers may be exposed to various risk factors while performing their duties without proper protection from law enforcement. Therefore, they could benefit from the work of private security which could provide regular patrol services and connect them to various social service agencies if needed. More research should be conducted to examine the viability of this extension of private security services.
