24x7 MDR for Defender

Fully tuned, expertly managed. 

Many organizations use Microsoft Defender, but few have the bandwidth to continuously tune it, investigate all alerts, and act quickly.

NuHarbor’s MDR for Defender offers 24x7 detection and response, purpose-built for speed, accuracy, and efficiency.

  • 24/7 detection and response from U.S.-based SOC analysts
  • Review every Defender alert and escalate only what matters
  • Operationalize your Microsoft investment with no new hires required

Talk to a MDR for Microsoft expert


“NuHarbor helped us tune Defender, focus on real threats, and respond faster. It’s a relief knowing someone’s watching when we’re not.”

We fine-tune your Defender endpoint environment to reduce false positives, enhance threat visibility, and automatically isolate threats before they spread. When deeper analysis is needed, our analysts step in, ensuring every alert gets the right level of attention without overwhelming your team.
