One firm, Selyutin and Partners, offers an audit to identify a company’s vulnerabilities, followed by workshops for top managers and other staff on dealing with law-enforcement agents—how to talk to them, how to react to threats or raids.

The organization provides legal and financial help to those it considers victims of prosecutorial machinations, especially businesspeople. For them, there’s even a verb for the practice, to “nightmare,” coined by Prime Minister Dmitry Medvedev when, as president in 2008, he ordered law enforcement agents to “stop nightmaring business.”
