The PSSA is the trade association for companies involved in the supply and installation of products designed to provide high levels of physical protection and intruder detection for sites and their external perimeters in all circumstances where terrorist or criminal attack is a perceived risk. We formally became a non-profit trade association limited by guarantee on 1st August 2009. Our founder members are some of the leading names in the sector – and we have been formed with the encouragement of the government body the Centre for the Protection of National Infrastructure (CPNI) which shares our objective to promote the use of high performance products and their professional installation. Members of the association supply a wide range of high performance high security perimeter protection products, many of which have been independently tested, and which include perimeter fences and walls, vehicle barriers and blockers, bollards, turnstiles, gates, detection systems, street furniture, and other specialist equipment developed for this demanding sector of the security market.
