Detect and neutralize cyberattacks that technology alone cannot stop
With bi-directional Microsoft integrations — compatible with M365 Business Basic and above — Sophos MDR uses proprietary detection rules and world-class threat intelligence to uncover sophisticated adversary activity that could evade traditional security tools and protect your organization from attack.

Extend your team with Microsoft Certified experts
The Sophos MDR team includes Microsoft Certified Security Operations Analysts specializing in detecting and responding to advanced cyberattacks using custom Microsoft response playbooks. Separating important alerts from the noise can be challenging, and many organizations lack the in-house expertise to use Microsoft's multiproduct technology to investigate and respond to hundreds or thousands of alerts every day. Sophos MDR provides the people, processes, and technology to effectively respond to Microsoft security alerts on your behalf.

Integrate an extensive range of technology solutions
Keep the cybersecurity software you already have and get more ROI from your technology investments now and in the future. Sophos MDR leverages telemetry from Sophos, Microsoft, and dozens of other vendors — spanning endpoint, firewall, network, email, cloud, identity, productivity, and backup solutions — to extend visibility and stop attacks across your entire environment. With deep integrations across Microsoft technologies — including Graph API, Entra ID, and the Office 365 Management Activity API — Sophos MDR harnesses telemetry and threat data from a wide range of Microsoft solutions, including:

Microsoft 365
Defender for Office 365
Defender for Endpoint
Defender for Cloud Apps
Defender for Identity
Entra ID Protection
Purview DLP
and more...

Rapid response to threats targeting Microsoft 365
The ability to respond quickly to a cyber incident is crucial — the faster the attack can be detected, contained, and neutralized, the less damage the attacker can inflict. When an attack is detected in your Microsoft 365 environment, Sophos MDR analysts can execute a range of response actions on your behalf — including blocking user logins, terminating active user sessions, and disabling suspicious inbox rules.

Protect against identity-based attacks
Sophos Identity Threat Detection and Response (ITDR) add-on: Powered by our deep bi-directional integration with Microsoft Entra ID, Sophos ITDR helps you detect and respond to threats that evade traditional identity security controls, strengthen your security posture, and monitor the dark web for compromised credentials. Fully integrated with Sophos MDR, it enables our security analysts to investigate and neutralize identity-based threats on your behalf.

Real-world expertise delivered using a world-class XDR platform
Sophos MDR unifies security data from across your environment with threat intelligence from Sophos X-Ops in a centralized, AI-native open XDR platform. Our expert teams across nine global SOCs use this platform to analyze, prioritize, investigate, and neutralize threats across your IT ecosystem.
