How Our MDR Service for Microsoft Sentinel Works

We help you prioritize the data being ingested into Microsoft Sentinel while applying Critical Start Indicators of Compromise (IOCs) to enhance threat detection. 

Our platform, which is tightly integrated with Microsoft Sentinel, automates the investigation and triage of alerts while eliminating false positives. True positives are then escalated to our Risk and Security Operations Center (RSOC) for further enrichment and investigation. 

And it doesn’t stop there—we continuously make recommendations on other data sources to add and update detection content to uncover new and emerging  attacks, giving you a better return on investment (ROI) from your Microsoft Sentinel solution. 

Partnering for Your Success

Achieve full security and business potential while simplifying breach prevention. 

Onboard quickly

Experience total time to value (TTTV) within 7 days with our proven process that shortens the time it takes to start seeing value. Go from onboarding to production in an average of 14.65 days and complete your total multi-product onboarding process within 4-6 weeks. 

Personalize based on your unique requirements

Improve threat detection and enrich the content needed for investigations when we help you prioritize your Sentinel data sources and create playbooks to reduce false positives. 

Investigate and resolve alerts

Get complete transparency and 24x7x365 security monitoring, investigation, and response from our U.S.-based RSOCs with guaranteed 60-minute or less Time to Detect (TTD) and Median Time to Resolution (MTTR) SLAs on every alert, regardless of criticality. 

See a boost in your team’s efficiency with an approximately 90% reduction in false positives on the first day of production monitoring. Plus, we’ll never send you the same alert twice. 

Mature your Sentinel investment

Experience a real partnership with your named Customer Success Manager, who will check in with you regularly to ensure our services are still meeting your needs after onboarding — even as your requirements change. 

Give your team more time to focus on strategic initiatives while we help you achieve full operating potential and threat detection from your Sentinel security investment.
