What CSG Computer Services Group does

CSG Computer Services Group (legal entity: CSG Computer Services Ltd) is a privately held UK Managed Service Provider (MSP) and Managed Security Services Provider (MSSP) founded in 1985 by Ron Vyse and headquartered in Bridgend, Wales, with regional offices in Bristol, Exeter, and Cardiff. The company delivers IT support, cloud, cybersecurity, telephony, and consulting services to over 400 businesses across the UK, with particular strength in the South Wales and South West England markets. Its core technology stack is built around the Microsoft cloud ecosystem (Azure, Microsoft 365, Teams, Copilot), Sophos cybersecurity (including Sophos MDR for 24/7 threat monitoring), Datto/Kaseya backup and disaster recovery, and Pegasus Opera business software.

The company organises its offering into three pillars — Consult (IT strategy, cloud consulting, security & compliance, AI adoption), Transform (managed IT support, cloud services, infrastructure change, cloud telephony), and Protect (24/7 cyber protection, Cyber Essentials certification, disaster recovery, cyber awareness training). Service delivery is direct, via dedicated account managers and a 24/7 helpdesk, supplemented by a CSG Client Portal for ticket management. Revenue is generated primarily through recurring managed services subscriptions (annual contracts), supplemented by professional services consulting engagements and pass-through vendor licensing for Microsoft, Sophos, and Datto solutions.

CSG holds top-tier vendor certifications including Microsoft Solutions Partner, Sophos Platinum and Gold Partner, Pegasus Platinum Partner (one of only four in the UK), Kaseya/Datto Platinum Partner, and Cyber Essentials Plus from the NCSC. The company is founder-led in its institutional culture but currently operates under Managing Director Matthew Bater. It is privately owned with no disclosed external funding, no parent company, and operates exclusively in the UK market.
