Microsoft Defender XDR Security Services

Practice 01

Endpoint Security & Identity Protection

Modern attacks frequently target endpoints and identities to gain unauthorized access and move laterally across environments. SourceMash strengthens enterprise security by integrating Microsoft Defender for Endpoint (MDE), Defender for Identity (MDI), and Microsoft Entra ID into a unified protection framework. Through behavioral analytics, attack surface reduction policies, and continuous identity monitoring, organizations gain deeper visibility, faster threat detection, and stronger access control across hybrid environments.
Key security outcomes include:
• Real-time endpoint threat detection
• Active Directory & Entra ID protection
• Risk-based access enforcement
• Reduced attack surface exposure
• Faster investigation and response

Common Questions

Frequently Asked Questions

Everything you need to know before reaching out to us.

Do We Need to Deploy Separate Agent Packages for Microsoft Defender for Endpoint?

No. For Windows 10, Windows 11, and modern Windows Server environments, Microsoft Defender for Endpoint is built directly into the operating system. Activation and policy management can be delivered through Microsoft Intune and Microsoft security services without requiring additional endpoint agents, reducing deployment complexity, system overhead, and ongoing maintenance requirements.

What Is Automated Investigation and Remediation (AIR) in Microsoft Defender XDR?

Automated Investigation and Remediation (AIR) is a native threat response capability within Defender XDR that helps security teams respond to incidents faster. When high-confidence threats are detected, AIR automatically investigates affected devices, analyzes suspicious activities, isolates malicious artifacts, and recommends or executes remediation actions. As part of SourceMash's Microsoft Defender XDR Security Services, AIR helps reduce response times and enables faster threat containment with minimal manual intervention.

How Does Microsoft Defender for Identity Protect On-Premises Active Directory?

Microsoft Defender for Identity (MDI) enhances security across Active Directory and hybrid identity environments by deploying lightweight sensors on domain controllers. These sensors continuously analyze authentication traffic, directory activities, and user behaviors to identify identity-based attacks such as credential theft, privilege escalation, suspicious lateral movement, Kerberos abuse, and password-spraying attempts in real time.

Can Microsoft Defender XDR Integrate With Third-Party Ticketing and SIEM Platforms?

Yes. Microsoft Defender XDR supports integration with external platforms through Microsoft Graph Security APIs, Microsoft Sentinel, and Azure Logic Apps. SourceMash can configure automated workflows that route security incidents, alerts, and investigation data to solutions such as ServiceNow, Jira, and third-party SIEM platforms, helping organizations maintain centralized visibility and streamlined incident management across their entire security ecosystem.
