As part of the BBC's African Dream series, Divine Ndhlukula explains how she was inspired to set up her company - Securico - after spotting a niche in the security market in the late 1990s.
What started as a cottage-based business with four employees and very little capital has now become one of Zimbabwe's largest security firms.
African Dream is broadcast on the BBC Network Africa programme every Monday morning, and on BBC World News throughout the day on Fridays
