Watch out for
- Pricing is opaque — requires direct engagement with Microsoft sales and a high seat minimum (1,500)

Questions
What is the difference between Microsoft Defender Experts for XDR and Defender Experts for Hunting?
Defender Experts for Hunting is a proactive, human-led threat hunting service designed for organizations that already have a mature SOC and want additional expertise to find hidden adversaries. Defender Experts for XDR is a full managed detection and response (MDR/MXDR) service where Microsoft analysts triage, investigate, and actively respond to incidents on your behalf around the clock.
Does Microsoft Defender Experts require Microsoft 365 E5?
Yes — Microsoft 365 E5, Microsoft 365 E5 Security, or the equivalent standalone Microsoft Defender licenses are prerequisites. The Defender Experts Suite, launched in January 2026, also accepts Microsoft Defender and Purview Frontline Workers licensing as a qualifying prerequisite.
Can Defender Experts monitor non-Microsoft cloud environments?
Yes. Through Microsoft Defender for Cloud, the service extends investigation and response to workloads running on AWS and Google Cloud Platform in addition to Azure, giving security teams cross-cloud visibility from a single console.
