TwinStream is a Cheltenham-based security engineering firm that turns NCSC patterns into cloud and hardware security implementations for defense and government clients.
TwinStream, founded in 2019 and headquartered in Cheltenham, UK, works on cross-domain security problems for defense, national security and government clients. The company's core work involves translating National Cyber Security Centre (NCSC) patterns into real-world implementations, combining cloud and hardware security technology with complex systems engineering. Its technical domains span cross-domain security, cloud security, hardware security and wider cyber security.
The founding team brings decades of combined experience in defense and security organizations. TwinStream operates on-site with clients as well as through distributed, remote teams, and has embraced hybrid working from the outset. Engineering work is organised around shared knowledge rather than individual silos, with an emphasis on internal developer communities built on collective expertise and on technical excellence.
The company describes itself as mission-driven, focused on helping organizations stay ahead in the cyber arms race. Growth, learning and technical collaboration are stated priorities, and internal mobility is supported; Delivery Managers, for example, have moved towards developer roles.
