About Us


When Hart began in 1999, it was formed to provide specialist security with capabilities across the land, sea and air environs. Initially called the Hart Group, the vision was to build a family of companies that offers integrated, end-to-end solutions for our clients.

Over time this vision has become a reality: the group has grown to include specialised managed services (CTG Global), risk management and security (Hart), aviation security (Longport), leadership development (The Leadership Trust), power generation (Symbion Power) and strategic consultancy (Enigma Alliance) which also includes camp operations (COG), portable housing (NapCap), water-purifying solutions (WaterCap) and software development (T-Rex Games).

These fully independent companies within the Group provide best-in-class services around the globe, and employ over 8000 personnel on the five main continents with over 50 offices worldwide. The Chelsea Group has impressive management teams offering decades of diverse experience; together we can offer our clients truly holistic and integrated solutions in some of the most challenging environments.
