Delivering mission-critical capability in complex environments

The Ministry of Defence is driving a fast moving transformation programme to deliver modern, open and flexible IT which is agile and innovative. Information superiority and collaboration with coalition forces, intelligence and law enforcement agencies is seen as vital to defend against increasing physical and cyber security threats. For 40 years we have been a global provider of information services to the defence and intelligence agencies of the UK, Canada, USA and across Europe. We bring expertise in multiple IT disciplines and knowledge of other commercial and public sector solutions to Defence.
