About us

Our History

Dent’s is the Cambridge security specialist. Founded in 1870 by locksmith Robert Dent, he provided a service to the University and to the terraced housing expansion in Cambridge city at that time.

In the mid 1990s Dent Security was established to meet the increasing need for intruder alarms and electronic security to work alongside the traditional locksmiths. Our goal was to bring Dent’s traditions of quality and service to the high tech security industry.
