5. Integration with Microsoft 365 Defender
Microsoft Defender for Endpoint is a key component of Microsoft 365 Defender, an interconnected, XDR (extended detection and response) solution that provides coordinated defense across domains. It enables organizations to prevent, detect, investigate, and respond to attacks with built-in intelligence and automation.
With Microsoft 365 Defender:
- Threats are auto-healed: In situations where threats such as phishing attacks are detected, Microsoft 365 Defender can automatically heal affected assets.
- Threat Analytics: In-depth analysis of new and evolving threats provide additional context, including how the threat was introduced, how many endpoints were affected, and what actions the threat is taking.
- Unified experiences: It provides a unified Experiences across Security Center and the Microsoft 365 security portal.
With this in-depth understanding of Microsoft Defender for Endpoint, candidates for the SC-900 exam, “Microsoft Security, Compliance, and Identity Fundamentals,” can be well-prepared to tackle questions related to Microsoft’s endpoint security offerings.
