Fortress Red helps organisations establish a SECRET secure digital environment quickly, giving teams access to UK sovereign infrastructure to enable them to bring their own applications or select from our existing pre-approved applications from the outset.

Designed for high-assurance programme delivery, Fortress Red supports specialist workloads including, but not limited to BIM, PLM, CAD, CAFM, PMO, secure DevSecOps, software development, digital twins, augmented reality and extended reality. It enables engineering teams, software developers, programme managers and delivery partners to begin productive critical work from day one.
Remove Mobilisation Barriers Before They Delay Delivery
Winning a contract is only the beginning. Before delivery can start, organisations often need to establish secure infrastructure, deploy specialist applications, onboard users, provide partner access and complete assurance activity. Each step can add time, increase programme risk and put critical milestones under pressure.
Fortress Red reduces that friction by providing an established UK sovereign secure digital environment designed for secure engineering, secure DevSecOps, collaboration and programme delivery from the start.
