Smart capabilities require sharp minds. 3SDL brings the brightest and best to our defence and security clients

Our expansion from data links to services across the full spectrum of C4ISR, Space and Cyber capabilities has created a breadth of operational understanding that we couple with our deep technical expertise.


We remain true to that purpose and the values that 3SDL is built on. Now with a team of over 50 hand-picked experts in their specialist fields, we continue to solve complex operational challenges and deliver imaginative solutions to defence and security clients across the globe.

Our expansion from datalinks across the full spectrum of C4ISR, Cyber and Space services has brought a breadth of operational understanding that is coupled with deep technical expertise.
We bring this understanding to our clients through collaborative and agile solution development, applied
innovation and adaptation of technology and training. Our independence, flexibility and the pragmatic application of operational experience has earned us a global reputation for delivering exceptional capability solutions, not just equipment projects.
We are proud with our coveted Silver Award under the UK MoD’s Employer Recognition Scheme and our clients benefit hugely from the unique skills and experience of our military veterans and Reservists.
Our operators, engineers and highly skilled support staff create an invigorating working environment that inspires us to think faster, deeper and smarter about global security and the challenges our clients face. 3SDL may still be a small company – but we now have the big picture.
