The book is addressed to representatives of small and medium-sized businesses operating in Russia and the countries of the former USSR. It analyzes criminal schemes and methods that pose a serious danger to any business and its owner. The insidiousness of many of the techniques and methods used is revealed, based on the fact that a businessman finds out about what happened too late - when it is already useless to do anything. Therefore, along with the analysis of criminal schemes (fraud, raiding, etc.), the book provides valuable advice, specific recommendations and direct guidelines for action, allowing you to neutralize the danger in time and save the business.
