Unleash Your Cybersecurity Superpowers with Microsoft Sentinel’s Integration with Microsoft 365 Defender

In the fast-paced world of cybersecurity, you need robust solutions to protect your valuable assets. Microsoft Sentinel’s integration with Microsoft 365 Defender brings together two powerful tools, creating a dynamic duo that bolsters your defence against modern threats.

Microsoft 365 Defender is a comprehensive security solution that focusses on protecting your organisations digital assets within the Microsoft 365 ecosystems. It brings together a bunch of security tools and services to provide an integrated defence against cyber threats. On the other hand, Sentinel is a cloud-native Security Information and Event Management (SIEM) system. It’s there to provide intelligent security analytics and responses.

Microsoft Defender 365:

  • Primarily focuses on securing Microsoft 365 products and services such as, endpoints, identities, productivity tools and cloud apps.
  • It’s tightly integrated with 365 products, allowing rich telemetry and intelligence.
  • Uses AI and machine learning to detect and respond to security incidents.
  • Defender puts a strong emphasis on endpoint security, allowing you to monitor and secure endpoints from a centralised platform.

Microsoft Sentinel:

  • Offers a broader coverage across various cloud platforms, applications and on-premises systems.
  • Ingest and analyse security data from different sources, including logs, events and alerts – regardless of the technology stack.
  • Flexible and scalable platform so you can customise data connectors, create tailored detection rules and build automation workflows.
  • Advanced analytics, machine learning and threat intelligence – all to help your analysts identify patterns, investigate incidents, and response to events effectively.

So, while Microsoft 365 Defender focuses on securing the Microsoft 365 environment, Microsoft Sentinel can integrate with Microsoft 365 Defender incidents and data. This integration enables a unified view of security incidents across the organisation, combining the strengths of both platforms.

So what do you get when you integrate Sentinel with Defender 365?

Streamlined Incident Management:

With Microsoft Sentinel’s integration with Microsoft 365 Defender, you can seamlessly stream all Microsoft 365 Defender incidents into Sentinel, ensuring a synchronised view of your security landscape. By centralising incidents from multiple sources, including Microsoft 365 Defender’s alerts, entities, and contextual information, you gain a comprehensive understanding of potential threats. This streamlining enables you to perform triage, investigation, and resolution all within the Sentinel portal, eliminating the need to switch between multiple tools.

Maximise Visibility and Correlation:

The integration empowers you to manage Microsoft 365 security incidents alongside other cloud and on-premises systems, giving you a holistic view of your organisation’s security posture. Correlating Microsoft 365 incidents with alerts from various sources provides valuable context for faster and more accurate decision-making. Additionally, Microsoft 365 Defender’s alert grouping and enrichment capabilities reduce the size of your incident queue, ensuring quicker time-to-resolution and increased operational efficiency.

Tap into the Power of Microsoft 365 Defender:

Microsoft 365 Defender combines several essential services:

  • Defender for Endpoint,
  • Defender for Identity,
  • Defender for Office 365,
  • Defender for Cloud Apps, and more.

These services enrich and consolidate alerts, creating a cohesive security ecosystem. By integrating Microsoft 365 Defender with Sentinel, you gain access to its unique strengths and capabilities tailored specifically to the Microsoft 365 environment. This integration enhances your ability to perform deep investigations, leverage advanced hunting events, and unleash the full potential of Microsoft 365 Defender’s comprehensive security offerings.

Seamless Integration and Easy Setup:

Getting started with Microsoft Sentinel’s integration with Microsoft 365 Defender is a breeze. We’ll work with you team to installing the Microsoft 365 Defender solution for Sentinel and enabling the data connector to collect incidents and alerts. Within minutes, you’ll start seeing Microsoft 365 Defender incidents appear in the Sentinel incidents queue, ready for analysis and response. The integration is seamless and incurs no extra cost, making it an accessible and value-packed addition to your security arsenal.

Boost Collaboration and Efficiency:

Bi-directional synchronisation between Microsoft Sentinel and Microsoft 365 Defender ensures that incident updates made in either portal are reflected in real-time, enabling seamless collaboration between teams. Changes in incident status, assignment, or closing reasons are instantly synchronised, allowing for smooth handoffs and efficient incident management. With both tools working in harmony, your security operations centre (SOC) gains enhanced visibility, accelerates incident response, and optimises resource allocation.

Harness the Power of Advanced Hunting:

In addition to incident management, the integration allows you to stream advanced hunting events from Microsoft 365 Defender and its components directly into Microsoft Sentinel. This raw event data provides deeper insights and enhances your ability to correlate events from multiple sources. You can easily migrate existing advanced hunting queries and leverage the full set of advanced hunting events within Sentinel. With increased retention options, you can store logs beyond the default 30-day period, enabling long-term analysis and comprehensive investigations.


By harnessing the integration between Microsoft Sentinel and Microsoft 365 Defender, you unlock a world of possibilities for your cybersecurity strategy. Seamlessly manage incidents, gain comprehensive visibility, and tap into the power of Microsoft 365 Defender’s specialised security capabilities. Boost collaboration, efficiency, and incident response while unleashing the potential of advanced hunting events. It’s time to embrace your cybersecurity superpowers and protect your organisation with this unbeatable combination. Activate the integration today and take your security defences to new heights!
