CRITICALSTART Managed Detection and Response Services for Microsoft Defender for Endpoint

CRITICALSTART built an MDR service with Microsoft Defender for Endpoint that goes beyond monitoring alerts to helping customers see attacks across hybrid device types and operating systems. CRITICALSTART MDR analysts and your own team can investigate the context of alerts and remediate the true positives. Because no one has time to waste. 

Meet a SOC Analyst

Senior SOC Analyst Davis Kouk explains how CRITICALSTART‘s SOC delivers Managed Detection and Response services for Microsoft Defender for Endpoint, including the ability to isolate hosts and add value with additional alerts that don’t come built into Defender for Endpoint.

Simply better visible threat detection and response 

Resolve all alerts

  • Trust oriented approach leverages the power of the Zero Trust Analytics Platform™ (ZTAP™) and Trusted Behavior Registry™ (TBR) to address all alerts 
  • We resolve more than 99% of alerts  
  • We escalate less than 0.1% of alerts – the alerts that really require the attention of your security team 

Automated security + control to help you focus on what matters

Microsoft Defender for Endpoint is built on deep insights into operating system threats and shared signals across devices, identities, and information. Leveraging Microsoft automated alerts and actionable incidents, decide what to prioritize next on your Microsoft Roadmap and leave the research, false positives, and containment of infected devices to Microsoft and CRITICALSTART. 

Integration, the better way

CRITICALSTART™ MDR services for Microsoft Defender for Endpoint leverage:  

  • Cross-operating system (Windows, Mac, Linux) Indicators of Compromise (IOC)  
  • Azure Active Directory as an identity provider, single sign-on, and user provisioning management 
  • Microsoft automated alerts and actionable incidents  
  • Cross-signal context in device timeline investigations
  • Ability to pivot directly to the device timeline from any generated IOC 

Goodbye portal fatigue

Comprehensive integration accelerates investigation and response with access to Microsoft Defender for Endpoint or Microsoft 365 Defender. Get Entities, Secure Score, Sign-In Details and related alertsall in one portal. For each type of data source, such as email, identity and endpoint, we have built queries within this single portal so you can fetch other information for additional context. 

Next-level expertise

  • Security analysts have MS-500: Microsoft 365 Security Administration, SC200 and AZ-500:  Microsoft Azure Security Technologies certifications 
  • Microsoft Security Best Practices are used to deploy Microsoft Defender for Endpoint to optimize Microsoft content for both Scheduled Query Rules and Indicators of Compromise (IOCs) 
  • We deliver 24x7x365 end-to-end monitoring, investigation, and response by highly skilled analysts 

IOC Management? Hello optimized rules.

A key feature of the MDR service for Microsoft Defender for Endpoint is IOC management. Microsoft is the fastest-moving security company today. IOCs are published and updated hourly across different locations. Leveraging the CRITICALSTARTThreat Navigator, we manage, maintain, and curate MDE out-of-box detections and IOCs.  Detection content is also mapped to the industry leading, MITRE ATT&CK® framework.
