Microsoft Incident Response (IR) is a specialized cybersecurity service that supports organizations during active security incidents and helps them recover, secure, and strengthen their environments against future attacks. Delivered by Microsoft’s security experts and [formerly branded as DART (Detection and Response Team)](https://learn.microsoft.com/en-us/security/ransomware/incident-response-playbook-dart-ransomware-approach) or CRSP, Microsoft IR includes both reactive breach response and proactive security services like vulnerability assessments and threat hunting. This service is offered as a standalone product and is no longer tied to Microsoft Unified Support or Enterprise Agreements (EA), allowing broader access across Microsoft’s customer base. Microsoft IR is known for its: - Global threat response expertise - 24/7 availability during incidents - Phased response model (including containment, investigation, recovery, and post-incident improvement) - Deep integration with Microsoft’s security ecosystem and research Yet many organizations discover that while the initial response may be swift, implementation of recommendations and long-term support often require internal resources—or additional Microsoft add-ons. That’s where third-party support providers like US Cloud step in to fill critical gaps in remediation, planning, and cost control. ## Key Capabilities of Microsoft IR Below are some of the main capabilities behind the Microsoft IR service. ### Reactive Incident Response - Immediate containment of active threats - [Forensic analysis](/microsoft-support-glossary/incident-forensics/) and root cause determination - Malware analysis and attacker eviction - Coordination with in-house teams and law enforcement where necessary ### Proactive Services - [Security posture](/microsoft-support-glossary/security-posture/) assessments - Threat intelligence briefings - Threat hunting within your environment - Simulation exercises to test readiness ## Phased Engagement of Both US Cloud & Microsoft IR Microsoft IR engagements typically follow four phases: - Initial Containment - Investigation and Analysis - Eradication and Recovery - Post-Incident Review and Hardening These phases help structure the response effort, but depending on the complexity of your environment, execution can vary significantly. Microsoft IR often depends on the enterprise’s internal capabilities to execute necessary security measures whereas, with support through US Cloud, engineers can both provide the assessment and proactively support your team through system hardening. ## Accessing Microsoft IR Without Unified Support Contrary to outdated assumptions, Microsoft IR can be directly purchased without: - A Microsoft Unified Support agreement - A Microsoft [Enterprise Agreement (EA)](/microsoft-support-glossary/enterprise-agreement/) This standalone model allows Microsoft-dependent organizations to engage Microsoft IR hourly or through a retainer, which guarantees a two-hour response time. This is especially relevant for enterprise IT and security leaders who have moved off Unified Support to save costs but still want access to premium Microsoft cybersecurity services. At US Cloud, we ensure our clients can retain full access to Microsoft IR while escaping the high costs and lock-in of Microsoft’s Unified Support model. ## Why Enterprises Partner with US Cloud Instead US Cloud helps organizations simplify their Microsoft relationship while maintaining top-tier cybersecurity readiness. Here’s how we enhance the Microsoft IR experience: - **Faster Remediation:** While Microsoft responds to incidents, we guide your team through implementation of recovery plans and system hardening. - **Security Advisory + Support:**We don’t stop at analysis. Our team ensures real, operational improvements are made post-incident. - **Booz Allen Hamilton Partnership:** Our clients gain access to elite incident response capabilities at 50% less cost—backed by national security-grade expertise.
