CrowdStrike Adds Threat Hunting for Microsoft Defender

CrowdStrike has launched Falcon OverWatch for Defender, extending its managed threat hunting service to organizations using Microsoft Defender for endpoint security. The move gives Microsoft Defender customers access to CrowdStrike’s expert-led hunting, adversary intelligence, and response guidance without requiring them to move away from their existing endpoint deployment.

Many organizations have standardized on Microsoft security tools, especially through broader Microsoft licensing agreements. That creates a large base of customers running Defender, but it also leaves room for managed security providers to add higher-touch services around detection, threat hunting and response. CrowdStrike is positioning OverWatch for Defender as a way to find stealthy activity that automated endpoint detections may miss.

For MSSPs, the service is directly tied to the pressures they face inside security operations. Providers are being asked to reduce alert noise, improve detection quality, and respond faster without adding more analysts for every new customer. CrowdStrike says Falcon OverWatch can reduce alert volume, improve true positives and lower threat hunting staffing costs.

Microsoft security environments are becoming a bigger opportunity for MSSPs. Many customers want to keep Defender as their endpoint tool, but they still need help finding and responding to threats that move quickly or hide inside normal activity. For MSSPs, that creates room to build managed threat hunting services around Microsoft deployments and show customers clearer security outcomes.
