Twinstream

TwinStream designs and implements cross domain solutions, which control how data is received into and shared out of an organisation's systems. Its work follows National Cyber Security Centre guidance and uses techniques such as uni-directional flows, protocol breaks and data transformation and verification. Services cover concept definition and strategy, cross domain solution implementation following the four phases of Discovery, Alpha, Beta and Live, and ongoing service management.

The company works with organisations that need to protect sensitive data and share information with other organisations, and its founders previously worked as engineers on cross domain problems in defence and security organisations. It operates as a services business that delivers projects for clients. TwinStream holds Cyber Essentials Plus accreditation and follows Agile methodologies.

TwinStream was founded in 2018 and has five founders. Its team is remote-first, with most employees working from home and a small number working at client sites. The business is based in Cheltenham, and the company is registered in Stratford-upon-Avon. It is recruiting for open roles.
