The Critical Start Difference

  • We do what others don’t. 
    Critical Start provides deep integration with the Microsoft security suite to detect every event, resolve every alert, and respond to breaches. We reduce risk acceptance and magnify security visibility by leveraging the deep cybersecurity insights and capabilities that make the Microsoft security stack different from other Extended Detection and Response (XDR) solutions. 

  • We resolve every alert, regardless of criticality.
    MDR services leverage the Cyber Operations Risk & Response™ platform to collect, understand, and resolve incidents across the Microsoft environment. Our platform enriches every alert with additional metadata from the Microsoft environment. Our service also features our Trusted Behavior Registry® (TBR®), the largest registry of known-good alerts (false positives), delivering the scalability to resolve every alert. 

  • Seamless integration.   
    Our services integrate with, leverage, and optimize Microsoft security solutions for enhanced threat detection and response outcomes. Integration with the Microsoft security suite is engineered to enforce secure access. We only request the minimum level of permissions needed, and we never ask for highly privileged roles such as Global Administrator.    

  • Leverage the resources you already have.  
    Extend your team with highly skilled Microsoft Security experts for 24x7x365 threat detection and response coverage backed by contractual Service Level Agreements (SLAs) for a 60-minute or less Time to Detect (TTD) and Median Time to Resolution (MTTR). Several security analysts are also Microsoft Certified as Security Operations Analyst Associates
