Crowthorne’s security specialists for almost 30 years

Established in December 1988, DSC Security started off in a small office in Bracknell. At first, owners Ian Jolley and Les Rayment focused mainly on supplying and installing locks, safes, and access control equipment. However, the growing demand for CCTV and Intruder Alarm Systems led us to expand our services to a shop space on Crowthorne High Street in 1990.

By January 1998 DSC Security had acquired a local intruder alarm company 4KL Security. This new addition brought their core clientele of home builders to our books, allowing us to establish good relationships with many developers. Over the years, we’ve undergone several changes but our dedication to remaining one of the Thames Valley’s leading security companies has never wavered.
