Yoon & Yang’s Corporate Investigations & White Collar Defense Practice Group provides optimal legal services in the criminal field related to all investigations handled by all national investigative agencies such as the Ministry of Food and Drug Safety, the Korea Customs Service, and the Regional Environment Agency, the Board of Audit and Inspection, the National Tax Service, the Fair Trade Commission, and the Financial Supervisory Service.

In addition, Yoon & Yang has the Digital Forensics Center providing data analysis and advisory services for various criminal issues arising from the rapid development of technology and industry sectors, including the fields of knowledge and information.

The Group has also improved both the quantity and quality of legal services by recruiting key professionals. Given that the scope of the prosecution's investigation, which was once reduced due to the adjustment of investigative rights between the prosecution and police, has recently been expanding again, such active recruitment of talent will be a turning point for the Group.
