Built on Microsoft’s integrated Defender XDR and Sentinel SIEM platforms, our solution combines world-class tooling with demonstrated expertise to protect your organization from today’s most advanced threats.

Where other services and technologies flood security teams with noise, we apply our expertise and proprietary innovations to reducing your effort and increasing security value. NuHarbor’s Best eliminates noise and delivers fully contextualized alerts that resolve to either a verified threat or a false positive. The result is faster incident response, smarter security outcomes, and less alert fatigue.
