CRITICALSTART Managed Detection and Response Services for Microsoft Sentinel (formerly Azure Sentinel)

Most Security Information Event Management (SIEM) solutions are leveraged for compliance, but only partially optimized for threat detection. CRITICALSTARTMDR services integrate with Microsoft Sentinel to detect every event, resolve every alert, and escalate only the alerts that matter to you.  We provide you full operating potential for threat detection and response, while providing your security operations team increased efficiency and productivity gains. 

SIEM is good…but this is better 

Resolve all alerts

  • Our trust-oriented approach leverages the power of the Zero Trust Analytics Platform™ (ZTAP™) and Trusted Behavior Registry™ (TBR) to address all alerts. 
  • We auto-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. 

Stronger MDR

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

Unmatched SIEM detection engineering expertise

  • Dedicated Cyber Threat and Detection Engineering team has a collective 100+ years of experience across multiple verticals/industries curating content to ensure detections are working.

  • Leveraging the CRITICALSTARTThreat Navigator, we manage, maintain, and curate Sentinel out-of-box detections and Indicators of Compromise (IOCs). 

  • Detection content is mapped to the industry approved MITRE ATT&CK® Framework.

  • Our services include CRITICALSTART proprietary detections and IOCs.  
  • We provide expert guidance around how to deploy Sentinel in your environment and optimize your log data sources for effective threat detection with the Microsoft Defender security suite or with other third-party security tools in your environment. 

How we do it

We take every alert from Microsoft Sentinel into ZTAP and match it against known good patterns in the TBR. If there is a match, the alert is automatically resolved and incorporated into the TBR. If there is no match, the CRITICALSTART Security Operations Center (SOC) investigates and collaborates with you to remediate the alert.
