What SYSTEM 15 does
System 15 Ltd is a UK-based managed IT service provider (MSP) founded in 2015 and headquartered in Quedgeley, Gloucester. The company delivers cyber-focused managed IT support to small and medium businesses (typically 10-50 staff), schools, and growing professional services and manufacturing firms across Gloucestershire, the wider South West, the UK, and parts of Europe. Its core offering is built around two productized managed service plans, S15 Insight (foundational proactive monitoring and support) and S15 Guardian (an upgraded, security-focused tier with 24/7 Microsoft 365 security monitoring, phishing simulation, and advanced AI-enabled protection tools), supported by standalone cyber security services, Microsoft 365 and cloud services (SharePoint, Intune, email migration), infrastructure management, user training, and project-based IT consultancy.
The underlying technology stack is Microsoft-centric: Microsoft 365, SharePoint, Microsoft Intune for endpoint management, multi-factor authentication, email security platforms, backup and disaster recovery, and 24/7 monitoring systems. System 15 holds Cyber Essentials, Cyber Essentials Plus, and IASME Cyber Assurance certifications, and its team claims over 30 years of IT project management experience. The company uses HaloPSA for support portal delivery.
The business model combines monthly recurring subscription revenue from managed service plans with project-based professional services (Microsoft 365 migrations, SharePoint implementations, Cyber Essentials certifications) and hardware leasing. The go-to-market is sales-led and regional, driven by direct outreach (phone, website contact forms), content marketing through a topical blog covering cyber security, M365, and AI risks, and regional PR through Circle2Success business awards. The company has been named a finalist or shortlisted for the Circle2Success Cyber and IT Business of the Year award for three consecutive years (2024-2026) and achieved Cyber Essentials Plus certification in April 2026.
