How XDR + SIEM + MXDR work together

Defender XDR

Microsoft Defender XDR collects, correlates, and analyzes threat signals and alerts from across the Microsoft 365 environment including endpoint devices, email, applications, and identities.

Sentinel SIEM

Microsoft Sentinel then correlates alerts provided by Defender XDR with a vast amount of external intelligence to detect and assess new threats.

NuHarbor MXDR

NuHarbor’s expert-led detection, response, and prevention then uses telemetry provided by both Defender XDR and Sentinel SIEM.

"Microsoft Sentinel is a powerful platform that can be adapted to the specific needs of each organization. NuHarbor has demonstrated their expertise in customizing and managing Sentinel solutions for optimal results."

Defenders are fighting an asymmetric battle

The increasingly targeted nature, volume, and speed of attacks makes defense unsustainable for security operations center (SOC) teams alone.

  • Security is one priority among many for your IT teams.
  • Attacks are constant and your vulnerabilities are rapidly changing.
  • Too many tools make patchwork security the default solution.
  • Each new platform can introduce more complexity and more noise.

Our dedicated team of security experts monitors your Sentinel environment 24/7 to ensure reliable threat detection, response, and remediation support. Efforts and disruptions from attacks are minimized through attack recognition tools, and embedded automations work to improve threat detection with similar characteristics.
