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 Security Operations Center (SOC) 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

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
