Our story since 1982
Founded in 1982, Central Southern Security (CSS) has grown into one of the South of England’s most trusted independent security specialists.
From our bases in Lymington (Hampshire) and Dorchester (Dorset), we’ve protected thousands of homes, schools, councils and businesses with reliable systems and honest, long-term personal support.
For over four decades our technology has evolved, but our approach hasn’t changed: we understand the site, recommend what’s right, and install it properly.
The result is a reputation built on reliability, responsiveness and straightforward advice.
