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 automated detection and response, purpose-built for speed, accuracy, and efficiency.



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