Atos UK&I Launches Sovereign MXDR Service for UK Cyber Resilience
United Kingdom – March 2, 2026
New managed security offering responds to heightened sovereignty requirements with UK-based security operations and AI-powered threat detection.
Atos, a global leader in AI-powered digital transformation, today launched a Sovereign Managed eXtended Detection and Response (MXDR) service specifically designed for UK government, critical infrastructure, financial services, and other UK organisations requiring stringent data sovereignty and regulatory compliance.
The new AI-powered MXDR service addresses mounting pressure on UK organisations to demonstrate complete control over sensitive security data, providing assured confidence following high-profile breaches through third-party security tools and growing concerns about access to UK infrastructure data.
A different approach to sovereignty
Unlike traditional managed security services that must copy or move customer data for analysis, Atos’ unique approach leverages Microsoft Azure’s delegated access architecture, ensuring data never leaves the customer’s environment. Combined with AI-enhanced 24/7 monitoring by security-cleared UK personnel operating from its new UK-based Sovereign Delivery Centre, this creates operational sovereignty without compromising security effectiveness.
“UK organisations need more than just security monitoring – they need a partner who understands UK threats, UK regulations, and UK business requirements,” said Terry Bebbington, Head of Cyber, Atos UK&I. “Our sovereign MXDR service delivers cyber resilience by combining decades of UK security experience with AI-powered threat detection and truly sovereign operations. This enables organisations to confidently defend against evolving threats whilst meeting their sovereignty and compliance obligations.”
The service integrates Atos’ established UK security operations – including Security Operations Centre (SOC), threat intelligence, and incident response teams that have protected UK infrastructure for over 15 years – into a single sovereign delivery model. AI-driven analytics and automated response playbooks accelerate threat identification and containment, while all operations, from initial detection through forensic investigation, are conducted by UK nationals from UK facilities, with resilience across multiple UK regions.
Meeting new regulatory expectations
The launch comes as organisations face increasing pressure to address evolving regulatory expectations around operational resilience and third-party risk management, particularly financial services under new Bank of England rules and critical infrastructure due to updated NIS regulations. The Atos service enables organisations to maintain security effectiveness whilst meeting stringent data localisation requirements.
With sovereignty now a boardroom issue, organisations must demonstrate to regulators, shareholders and government that their security operations are sovereign. The Atos MXDR service provides that assurance with complete transparency – customer data remains in their environment, monitored by cleared UK personnel using AI-powered security orchestration, with no offshore dependencies.
The service is available immediately through Crown Commercial Service frameworks, with UK government departments and critical infrastructure operators already engaged in deployment planning. Find out more here.
