System 15, the advisor-led managed IT services provider, is celebrating a decade of redefining how organisations approach technology, cybersecurity, and digital strategy. Founded in 2015 to challenge an industry dominated by jargon-heavy, reactive support models, the company set out to become a trusted strategic partner focused on clarity, security, and meaningful business outcomes. “Our mission was simple,” the directors Nick Rowntree and Richard Wood explain. “We wanted to build a partnership businesses could trust — one that delivers security, supports growth, and brings true strategic value.”
Over the last decade, System 15 has evolved from break-fix IT support to a fully advisor-led service that guides organisations through long-term digital planning, risk reduction, and modernisation. The business has expanded from its Gloucestershire roots to support clients across the UK and Europe, fuelled by investment in automation, cloud technologies, and advanced security capabilities. Key moments have shaped the company’s journey, including the shift from on-premises infrastructure to the cloud, the rapid rollout of remote collaboration during the COVID-19 pandemic, the surge in identity-based cyber threats, and the rise of AI, which has created both transformative opportunities and new vulnerabilities.
Client needs have changed significantly since 2015, with businesses increasingly seeking trusted advisors who can simplify complexity, strengthen security, and guide hybrid working and digital transformation. System 15’s board-level approach, deep discovery process, and best-in-class operating model set it apart from traditional providers. Security underpins everything the company does, with multi-layered protection strategies and continuous monitoring that analyses millions of events each month to protect clients from known and emerging threats.
One standout project illustrating System 15’s capabilities is the successful merger of two large educational organisations onto a unified, secure Microsoft 365 platform. The initiative delivered seamless data migration, device standardisation, application alignment, strengthened security, and user training — all completed with minimal disruption to teaching and administrative operations.
As cyber threats evolve and AI-driven attacks become more sophisticated, System 15 continues to invest in zero-trust principles, compliance frameworks, and real-time risk monitoring to safeguard its clients. Looking back over 10 years, the company celebrates its transition to advisor-led services, leadership in cloud migration, rapid response during the pandemic, advancements in cybersecurity, and expansion across the UK and Europe. These achievements reflect its ongoing commitment to clarity, trust, innovation, and exceptional technical expertise — values that will continue to drive the business forward into its next decade.
