An evolving threat landscape demands stronger, more adaptive protection
Identity-driven attacks
Business email compromise (BEC) and session hijacking routinely bypass MFA, making identity a primary entry point for attackers across Microsoft ecosystems.
Evasive, human-led ransomware
Adversaries use remote encryption and hands-on-keyboard techniques designed to evade Microsoft security solutions.
Operational and licensing gaps
High alert volumes and limited in-house expertise strain security teams, and organizations face visibility and response gaps without Microsoft E5.

Sophos MDR for Microsoft environments
24/7 managed detection and response that combines proprietary detections, Microsoft signals, and expert analysts to shut down threats, fast. Ideal for organizations running Microsoft technologies, or mixed environments that want an expert team to own cybersecurity outcomes, not just send alerts.
- Uses Microsoft signals to identify and protect against sophisticated attacks that technology alone cannot stop.
- Leverages telemetry from Microsoft Graph Security and Management Activity APIs
- Includes integrations with both Microsoft and non-Microsoft technology solutions for complete coverage of your IT estate.
- Rapidly executes response actions directly in your Microsoft environment, including revoking M365 sessions, disabling signins, and suspending malicious inbox rules.
- Use with Sophos Endpoint (included) or Microsoft Defender for Endpoint – you choose.

Sophos MDR is a Microsoft-verified Small and Medium Business (SMB) Solution through the Microsoft Intelligent Security Association (MISA), validating deep integration with Microsoft Defender for Endpoint and Defender for Business to deliver stronger, faster protection across Microsoft environments.
Sophos Identity Threat Detection and Response (ITDR) for Entra ID
Continuously scans Entra ID for misconfigurations and exposures, monitors for credential abuse including dark web findings, and enables analysts to take response actions in Entra ID to contain identity attacks, fast. Sophos ITDR elevates the native IAM capabilities of Entra ID with unmatched threat protection from Sophos.
Sophos Endpoint for superior ransomware protection
70%* of modern, human-operated ransomware attacks use remote encryption to avoid detection by tools including Microsoft Defender. Sophos Endpoint includes proprietary CryptoGuard technology to stop local and remote ransomware in its tracks. User-based licensing maximizes value when team members have multiple devices, including endpoints running legacy and out-of-support Windows operating systems.
Sophos Email for Microsoft 365
Integrates with Exchange Online to stop phishing and business email compromise attacks and adds user awareness training and phishing simulations, all without disrupting mail flow or Microsoft security policies.
Sophos Firewall for Microsoft environments
Sophos Firewall is optimized for Microsoft environments, with flexible hardware, virtual, and cloud deployment options (including Azure and HyperV), Entra ID integration for zero-trust remote access, and Azure Virtual WAN integration for SD-WAN overlay network deployments.
Taegis XDR with Next-Gen SIEM for Microsoft E5 + Sentinel
For enterprises that need SIEM-grade retention and cross-stack detection with predictable data storage economics, Taegis unifies Microsoft and non-Microsoft telemetry, integrates with Sentinel, and avoids variable events-per-second billing.
Sophos Intelix for Microsoft Copilot
Sophos Intelix brings Sophos X-Ops’ threat intelligence into Microsoft Security Copilot and Microsoft 365 Copilot, delivering smarter security, seamlessly within Microsoft environments. These integrations make advanced cyber intelligence instantly accessible where defenders, IT admins, and business users already operate.
