CRITICALSTART Managed Detection and Response Services for Microsoft 365 Defender

CRITICALSTART™ Managed Detection and Response Services for Microsoft 365 Defender deliver a radical approach to integrated threat detection and response. MDR and XDR are reinvented to focus on both containment and response actions for the Microsoft 365 Defender Security Suite. 

What Sets Us Apart 

We do what others don’t.

Microsoft has built a best-in-class security portfolio to stop attacks across Microsoft 365 services.  CRITICALSTART Managed Detection and Response services integrate with Microsoft 365 Defender to quickly detect every event, resolve every alert, and respond to breaches across all your  resources. 

One portal…seriously.

A comprehensive integration means you can speed up investigation and response with access to Microsoft Azure Sentinel or Microsoft 365 Defender, get Entities, get Secure Score, Sign-In Details, and related alertsall in one portal. For each type of data source like email, identity and endpoint, we also built queries within the platform for you to retrieve other information for additional contextstill all one portal. 

Resolving alerts is good. Resolving all alerts is better.

CRITICALSTART has built a comprehensive service for the Microsoft 365 Defender suite that allows you to leverage our unique trust-oriented model. Our MDR is driven by the Zero Trust Analytics Platform (ZTAP).  The platform features the Trusted Behavior Registry (TBR), the largest registry of known good alerts to reduce false positives, delivering the scalability to resolve every alert. 

Certified Microsoft expertise.

We are continuously investing in focused Microsoft resources, training and ongoing development around the Microsoft Security stack. Security analysts also have MS-500: Microsoft 365 Security Administration, SC200 and AZ-500:  Microsoft Azure Security Technologies certifications.  Our team also uses Microsoft Security Best Practices to deploy Azure Sentinel and Microsoft Defender 365 tools to optimize Microsoft content for both Scheduled Query Rules and Indicators of Compromise (IOCs).  

Automated investigations. Exceptional response.

ZTAP enriches every alert with additional metadata from the Microsoft environment. Leveraging Microsoft automated investigations and actionable incidents, our MDR service modulates and adapts for identity, checks for behaviors that are trusted, and escalates risky sign-ins, logons from unfamiliar IPs, and impossible travel violations for validation with enriched data. 

IOC Management on us.

A key feature of the MDR service for Microsoft 365 Defender is IOC management. Microsoft is the fastest-moving security company today. IOCs are published and updated hourly across different locations. Leveraging the CRITICALSTART™ Threat 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.

Integration, the better way.

  • Microsoft Azure Sentinel is leveraged for ingestion of alerts across your enterprise, automated investigations, and actionable incidents. 
  • Microsoft User and Entity Behavior Analytics (UEBA) which increases the likelihood of detecting a true positive at multiple parts of the kill chain. 
  • Azure Active Directory is leveraged as an identity provider, single sign-on, and user provisioning management. 

Never miss a threat. Or your desk.
