Sirius Open Source on G-Cloud 15

Sirius Open Source is proud to continue our long-standing partnership with the UK public sector as an approved supplier on the Crown Commercial Service’s G-Cloud 15 framework. For over two decades, we have championed the transformative power of Open Source Software (OSS) to deliver robust, scalable, and highly secure digital services. Our presence on G-Cloud 15 reaffirms our dedication to helping central government departments, the NHS, and local authorities modernise their IT infrastructure while achieving exceptional, sustainable value for public money.

At the heart of our offering is an unwavering commitment to genuine open-source values: transparency, collaboration, and digital sovereignty. We believe that public sector organisations should retain absolute control over their data and underlying technologies, completely free from the operational constraints and escalating costs of proprietary vendor lock-in. By architecting solutions around enterprise-grade OSS, we empower our clients to foster seamless interoperability, drive agile innovation, and redirect their IT budgets toward frontline service delivery rather than restrictive software licence fees.

Our ongoing mission is to bridge the gap between community-driven innovation and enterprise-class reliability. Through G-Cloud 15, Sirius provides a comprehensive suite of cloud hosting, software, and support services—from managed database solutions to fully sovereign cloud architectures. We do more than simply deploy open-source technologies; we provide the strategic guidance, 24/7 UK-based support, and technical assurance required to run mission-critical public services safely, securely, and transparently.
