Sophos Email Monitoring System
Enhanced visibility for existing email security identify missed threats and integrate email telemetry into MDR and XDR

Catch What Your Email Security Misses

Sophos Email Monitoring System analyses email traffic that has already passed through existing security controls identifying threats that were missed or misclassified by the primary email security layer. It operates without affecting mail flow, providing additional threat visibility across any email security service without requiring migration or replacement of existing email infrastructure.

• Monitors email without affecting mail flow or user experience.
• Detects phishing and business email compromise attacks that slip through existing defences.
• Identifies domain spoofing attempts not caught by the primary email security layer.
• Works alongside any existing email security service no migration required.

Remove Threats from User Inboxes

When the Email Monitoring System identifies a malicious message that has already been delivered to a user inbox, manual clawback removes it before the user can interact with phishing links or malicious attachments. Message evidence is preserved during and after clawback to support investigation and incident documentation.

• Manual clawback removes suspicious messages after delivery.
• Prevents user interaction with phishing links and malicious attachments.
• Preserves message evidence for investigation and audit purposes.
• Integrates with security team workflows for efficient remediation.

Connect Email Security to MDR and XDR

Sophos Email Monitoring System ingests email telemetry from any email security service and makes it available in Sophos MDR and XDR for threat correlation and investigation. This is particularly valuable for organisations using email security services that lack native MDR or XDR connectors the Email Monitoring System bridges that gap without requiring a change in email security provider.

• Works with email security services that lack native MDR/XDR connectors.
• Enriches email data with Sophos threat intelligence for deeper context.
• Correlates email events with endpoint, network, and identity security data.
• Enables full-context incident investigation across all data sources in one console.

Email Telemetry in Sophos MDR

When Sophos MDR is in use, email telemetry ingested by the Email Monitoring System is available to Sophos MDR analysts for threat hunting, investigation, and response. Analysts can correlate email-based indicators of compromise such as phishing links, BEC sender patterns, and domain spoofing with endpoint and network activity to build a complete picture of an attack chain.

• Email events available to MDR analysts for 24/7 threat hunting.
• Phishing and BEC indicators correlated with endpoint and network telemetry.
• MDR analysts can investigate email-originated attacks end-to-end.
• Email clawback actions can be triggered as part of MDR incident response.

Email Telemetry in Sophos XDR

Email telemetry ingested through the Email Monitoring System feeds into Sophos XDR for analyst-driven investigation. Security analysts can query email events alongside endpoint, network, cloud, and identity data using the XDR console enabling cross-domain investigation of attacks that originated via email and pivoted to other parts of the environment.

• Email events queryable in the Sophos XDR investigation console.
• Cross-domain correlation with endpoint, network, cloud, and identity data.
• Full-context investigation of email-originated attacks across the kill chain.
• Supports threat hunting queries across all retained data in the Sophos Data Lake.

Compatibility with Any Email Security Service

Sophos Email Monitoring System is designed to work alongside any email security service including Microsoft Defender for Office 365, Proofpoint, Mimecast, and others providing the MDR/XDR integration layer that many services lack natively. Organisations do not need to change their existing email security provider to benefit from this capability.
