An Assignment Planned Around Your Business
We begin by reviewing your concerns, the work environment and the objectives of the investigation. The assignment determines the operative’s role, the information to be gathered and the reporting schedule. Multilingual personnel may be available when needed for the setting.
MSI provides detailed written reports and periodic updates. Our investigators distinguish what they directly observe from information reported by others. When requested, we can coordinate with law enforcement and provide testimony concerning investigative findings.
Related Investigative Support
An undercover assignment may be supported by interviews, witness statements, surveillance, background research and security evaluations. The combination depends on the facts of the case and your priorities.
