Family-run business Cerberus Doors has just celebrated its sixth year of successful operation in the UK, during which time we have taken great pride in designing and installing high quality security front doors for homes and businesses. The manufacture of the doors takes place in Lithuania, but six years ago co owner Darius Virokaitis and his daughter Victoria decided to move the sales side of the business to the UK. This decision was driven by the discovery of a gap in the market for the design and installation of security doors that look like any other door, but have all the strength to deter even the most experienced and determined of burglars.
