    In 2005, Lars-Åke Severin, a native Swede, came to China to run a short-term project for a client. Severin, who is a former police officer in the Swedish Security Police Force and founder of the Close Protection Team for Her Royal Highness, the Crown Princess of Sweden, was acting CEO for a Swedish security consultancy firm at the time.

    During his stay in China, Severin experienced a multitude of challenges, while also absorbing the richness of Chinese culture and the warmth of China's people. He also immediately sensed a gap in the Chinese market for private security consultant services.


    The idea became a reality in 2006, when PSU became the first foreign company in China to obtain a business license as a security consultancy. Later that year, the company recruited its first employees, and soon PSU had a core group of highly qualified security professionals - both local and foreign.

    The company soon received a large number of projects, enabling rapid growth. In 2009, PSU opened a second office in Shanghai, which proved to be a strategically significant decision.


    PSU works as an expert team, providing consistent security development through preventive, investigative, and protective measures.

    With a combination of foreign and Chinese expertise, as well as extensive operational experience in China, PSU is a qualified and trustworthy supplier, securing and safeguarding its clients' operations and brands. We create value for our clients by identifying risks, reducing problems, and reducing economic losses.
