Microsoft Security Landscape


A SIEM (security incident and event management) system is a tool that an organization uses to collect data from across the whole estate, including infrastructure, software, and resources. It does analysis, looks for correlations or anomalies, and generates alerts and incidents.


A SOAR (Security Orchestration, Automation and Response) tool takes the input alerts from the SIEM system and uses its AI to understand what action and responses are needed to resolve security issues. The SOAR system then triggers action-driven automated workflows and processes to run security tasks that mitigate the issue.

Rapid incident response is extremely important for mitigating the damage caused by security threats and breaches. SOAR tools can help your security team drastically reduce both mean time-to-detect (MTTD) and mean time-to-respond (MTTR).

Microsoft Sentinel

Microsoft Sentinel – formally known as Azure Sentinel – is a scalable, cloud-native SIEM/SOAR solution that delivers intelligent security analytics and threat intelligence across the enterprise. It provides a single solution for alert detection, threat visibility, proactive hunting, and threat response. These four competencies neatly combine the features and use-cases of both SIEM and SOAR software. 

XDR (extended detection and response)

XDR is a SaaS-based security tool that draws on an enterprise’s existing security tools, integrating them into a centralized security system. An XDR pulls raw telemetry data from across multiple tools like cloud applications, email security, identity, and access management. Using AI and machine learning, the XDR then performs automatic analysis, investigation, and response in real time. XDR also correlates security alerts into larger incidents, allowing security teams greater visibility into attacks, and provide incident prioritization, helping analysts understand the risk level of the threat.

Microsoft 365 Defender for Enterprise, Business, Individuals (Formerly Microsoft Threat Protection)

Microsoft 365 Defender provides XDR capabilities for end-user environments (email, documents, identity, apps, and endpoint) and Microsoft Defender for Cloud provides XDR capabilities for infrastructure and multi-cloud platforms including virtual machines, databases, containers, and IoT.

Microsoft 365 Defender includes the following products:

Microsoft Defender for Endpoints

Microsoft Defender for Endpoints, formerly Microsoft Defender Advanced Threat Protection, is an endpoint detection and response (EDR) platform designed to help enterprise networks protect endpoints. It does so by preventing, detecting, investigating, and responding to advanced threats. Microsoft Defender for Endpoint embeds technology built into Windows 10 and MSFT cloud services.

Microsoft Defender for Identity

Microsoft Defender for Identity is a cloud-based security solution that leverages your on-premises Active Directory signals to identify, detect, and investigate advanced threats, compromised identities, and malicious insider actions directed at your organization. For identities managed on-premises, the solution integrates with Azure Directory Domain Services. For identities in the cloud, it is provided as an integral part of Azure Active Directory (Azure AD), called Azure AD Identity Protection.

Microsoft Defender for Office 365

Microsoft Defender for Office 365 is a cloud-based email filtering service that protects against malicious threats posed by email messages, links (URLs), and collaboration tools, including Microsoft Teams, SharePoint Online, OneDrive for Business, and other Office clients.

Microsoft Defender for Cloud Apps (formerly MCAS)

Microsoft Defender for Cloud Apps is a Cloud Access Security Broker (CASB). It’s a comprehensive cross-SaaS solution that operates as an intermediary between a cloud user and the cloud provider. Microsoft Defender for Cloud Apps provides rich visibility to your cloud services, control over data travel, and sophisticated analytics to identify and combat cyberthreats across all your Microsoft and third-party cloud services. Use this service to gain visibility into Shadow IT by discovering the cloud apps being used. You can control and protect data in the apps after you sanction them to the service. 

Microsoft Defender for Business

Microsoft Defender for Business is an endpoint security solution that helps businesses with up to 300 employees protect against cybersecurity threats including malware and ransomware

Microsoft Defender for Individuals

Microsoft Defender is a security app that helps people and families stay safer online with malware protection, web protection, real-time security notifications, and security tips.
