What Nasstar does
Nasstar is a UK-based managed IT and cloud services provider that delivers infrastructure, modern workplace, data and AI, networking, cybersecurity, and digital engineering services to large enterprises and public sector organizations. Core offerings are organized around the Microsoft Cloud ecosystem (Azure, Microsoft 365, Teams, Copilot, Entra, Fabric, and Foundry), supplemented by Secure Networks, Cyber Security & Compliance, Managed IT Services, and a dedicated Digital Engineering division operated under the Colibri Digital sub-brand (acquired February 2023, specializing in big data, data science, and AI consulting). Technology is delivered as a managed service stack built on strategic partnerships with Microsoft (10+ years), Cisco (20+ years), Fortinet (15+ years), AWS, and Databricks, with no proprietary platform disclosed.
The business operates with approximately 780 employees across the United Kingdom and Ireland from a Wakefield, West Yorkshire headquarters, serving verticals including Legal, Manufacturing, Energy & Utilities, Healthcare, Retail, Local Government, Professional Services, and Education. Named customers include NHS, South Yorkshire Mayoral Combined Authority, University of Glasgow, and Wiggin. Revenue is generated through recurring managed services subscriptions and project-based professional services on Microsoft Cloud, Secure Networks, Cyber Security, and Digital Engineering engagements, with pricing structured as quote-based annual subscriptions. Scale reached a reported record revenue of £200 million in FY22, with growth since driven by the 2021 KCOM national IT services acquisition, the 2023 Colibri Digital acquisition, and continued infrastructure modernization including a December 2025 strategic collaboration with Ribbon Communications on voice infrastructure. Compliance footprint includes ISO 27001 information security management and UK GDPR data protection.
