Managed Detection and Response Services

24/7 detection and response, accelerated by artificial intelligence and expert-led operations

Cyber resilience in an evolving threat landscape

Today’s cybersecurity challenge is not visibility alone. It is turning complexity into control. As threats accelerate across IT, cloud, identity, network, and OT environments, you need more than monitoring. You need a Managed Detection and Response (MDR) service that can detect, investigate, and respond with consistency, speed, and accountability. Atos MDR is built for that reality. It combines 24/7 threat detection and response, deep operational expertise, global threat intelligence, flexible delivery models, and vendor-agnostic integration across existing security investments. The result is a more resilient, outcome-driven security operation that helps organizations reduce dwell time, strengthen cyber resilience, optimize existing investments, and protect business-critical operations without unnecessary disruption.

Atos Managed Detection and Response services

Key features

Atos MDR is designed to deliver continuous, end-to-end security operations – bringing together visibility, expertise, and execution in a single, streamlined service. It ensures threats are not only detected, but investigated and contained with speed and consistency, aligned to business priorities.

24/7 threat detection and response

Detect and contain threats around the clock through continuous monitoring, triage, investigation, and response, including remote containment, guided remediation, and automation to minimize impact.

Full-stack visibility

Eliminate blind spots across the attack surface with unified coverage spanning IT, cloud, endpoints, identity, network, and OT/IoT environments.

Flexible delivery models

Choose the delivery model that fits your operating model, from fully managed, outcome-based MDR to hybrid approaches including bring-your-own technology and co-management.

Built-in AI augmentation

Accelerate investigation and response with virtual SOC Analyst automates enrichment, correlation, and first-line investigation, improving operational efficiency.

Atos embedded expertise

Benefit from advanced detection engineering, a dedicated Threat Research Center, and the scale of 17 global SOCs, bringing depth, intelligence, and consistency to every stage of defense.
