CyberOne Tech Stack

Microsoft-native managed XDR and security services for enterprise cloud environments

Computer and Network Security London, England 51–200 employees Founded 2005 Privately Held

CyberOne is a Microsoft Security Elite Partner delivering managed extended detection and response built on Microsoft's security platform (Defender XDR, Sentinel, Entra). The stack is almost entirely Microsoft-first—no competing SIEM adoption—which positions them as a pure-play implementation and managed-services partner rather than a platform vendor. Hiring is skewed toward security (5 roles) and mid-to-senior seniority, with active work on tenant migrations, cloud compliance (Purview DLP), and customer performance improvement, suggesting a services-delivery org scaling to handle enterprise cloud transformation.
