A useful security or investigation plan starts with a clear description of the assignment. Tell us the location, dates, coverage hours and concerns you want addressed. We discuss the proposed duties, information needed, reporting and scope before work begins.
For guards, that can mean defined access-control procedures, patrol areas, visitor assistance and incident reporting. For a Texas investigation, we review the purpose, authority, available information and lawful methods suitable for the inquiry. Findings and outcomes cannot be guaranteed.
