Defence & Security

Defence & Security

We are experts at taking commercially available components and ruggedising them for usage in defence applications. This allows our customers to unlock the advantages of cost-effective computing that meets exact requirements while significantly reducing development timescales. We also optimise the long term availability of our platforms, meaning software does not have to be updated to accommodate component changes caused by obsolescence.

We have developed a range of industrial computers, military servers, mobile computer racks and rugged tablets for use in defence and security applications, both civil and military, in the world’s harshest environments. Applications we’ve supported include flight and vehicle training simulators, ground satellite equipment, rugged vehicle tablets, mobile computer racks for the military and portable computers for redeployable video broadcast.

Owing to our success in the defence and security sector, we are recognised as an established member of the supply chain. All our computers can be customised to your exact needs and for highly complex applications, our innovative design to order service ensures even the most demanding requirements are fully met.
