MDR Services for Microsoft Sentinel™ (formerly Azure Sentinel)

Achieve the full operating potential of your Microsoft Sentinel investment.

Security and Information Event Management (SIEM) solutions can be complex. The combination of Microsoft Sentinel’s cloud-native scalability and CRITICALSTART®’s trust-oriented approach to managed detection and response (MDR) simplifies breach prevention and gives you comprehensive insight into your security coverage.

Key Benefits

Accelerate your return on your Sentinel investment

Prioritize the data to be ingested and increase visibility across your security environment.

Reduce the noise

Get fewer false positives while adding new Sentinel log source feeds.

Improve your security posture

Strategically add new data sources while continuously validating MITRE ATT&CK® Framework coverage.

Increase your SOC’s efficiency and productivity

We do all the heavy lifting for you with the combination of our Zero-Trust Analytics Platform® (ZTAP®) and seasoned security operations center (SOC) and Threat Detection Engineering teams.

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.

ZTAP, 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 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 more attacks so you get the most out of your Microsoft Sentinel investment.

Partnering for Your Success

Enhance the effectiveness of your MDR while simplifying breach prevention.

Onboard quickly:

We use a proven process that shortens the time it takes to take your operations live. The average time from onboarding to production is 14.65 days and the total onboarding process normally takes 4-6 weeks.

Personalize based on your unique requirements:

To improve threat detection and enrich the content needed for investigations, we’ll help you prioritize your Sentinel data sources and create playbooks to reduce false positives.

Investigate and resolve alerts:

You’ll get 24x7x365 security monitoring, investigation and response from our U.S.-based SOC with complete transparency and guaranteed one-hour SLAs for Time to Detection and Median Time to Resolution on every alert.

You can expect an approximately 90% reduction in false positives on the first day of production monitoring. We also boost your team’s efficiency by escalating only 1-2 alerts a day, and we never send you the same alert twice.

Mature your Sentinel investment:

Our relationship doesn’t stop after onboarding is complete. Your named Customer Success Manager will check in with you regularly to make sure that our services are still meeting your needs— even as your requirements change.

As we work together, we’ll continue to help you achieve full operating potential for threat detection. As a result, your team will have more time to focus on strategic initiatives, and you’ll get the most out of your Sentinel security investment.
