About us

Our History

At Dent’s, we have a rich history of providing security services to the Cambridge community. Our origins date back to 1870, when our founder Robert Dent began offering locksmith services to the University and the expanding terraced housing in the city. As the need for electronic security and intruder alarms grew in the mid-1990s, Dent Security was established to bring our tradition of quality and service to the high-tech security industry.

Today, Dent Security Cambridge continue to serve the community with the same commitment to excellence that has been our hallmark for over a century. Contact us for a free survey.
