What Esteem does

Esteem is a UK-based technology services group, founded in 1985 and headquartered in Woking, that aggregates cloud services and on-premise solutions for British customers. The group operates primarily through its managed services brand Roc Technologies (legal entity Roc Technologies Ltd, registered in the UK, with its principal office at Greenham Business Park, Thatcham), which delivers an integrated portfolio of five core propositions: Networking Transformation, Cloud Modernisation, Roc Cyber Consulting, Hyperautomation, and Roc Managed Services. The technology stack is anchored on the Microsoft cloud ecosystem, supported by specialist capabilities such as an AI-enabled Managed Security Operations Centre (MSOC) staffed by SC and DV cleared analysts, the Network Navigator network monitoring tool, SASE and perimeter security offerings, and the Interactive Smart Campus solution for higher education clients. Two sub-brands, Coria (data and analytics platform) and Illuminate (thought leadership and insights), extend the proposition beyond pure services delivery.

The business model combines subscription-based recurring revenue from managed services contracts with project-based professional services and specialist resourcing. All engagements are quote-based with no publicly disclosed pricing, and the go-to-market is sales-led with direct field engagement into named anchor accounts. Customer segmentation is vertical, with primary emphasis on UK public sector (higher education, local government, defence) and selected enterprise verticals (retail and legal). The customer base includes City of London Corporation, National Highways, University of Reading, and Aberdeen City Council (the last involving 167 sites and 34,000 students and educators). Demand generation is reinforced by the Shining Lights Podcast, the Illuminate insights platform, and case-study-led content marketing. Operational scale is supported by a comprehensive compliance stack (ISO 9001, ISO 14001, ISO 27001, ISO 45001, Cyber Essentials Plus) and four Microsoft Solutions Partner designations, with the firm ranked #2 in the Tussell Tech200 2026 as the fastest-growing UK public sector technology supplier.
