Tenable vs Microsoft Defender Vulnerability Management -- Vulnerability Management Compared
Microsoft Defender Vulnerability Management appeals to Microsoft-centric organizations as it is included with Defender for Endpoint P2, requiring no additional licensing or deployment. However, it provides significantly narrower vulnerability coverage compared to Tenable, focusing primarily on endpoint operating systems and browsers rather than the full IT, cloud, and OT estate that Tenable covers. For organizations deeply invested in Microsoft 365 E5, Defender VM is a cost-effective starting point, but enterprises with diverse environments will need Tenable's breadth.
Choose Microsoft Defender Vulnerability Management if you are a Microsoft 365 E5 organization wanting vulnerability visibility at no additional cost with native Intune remediation. Choose Tenable if you need comprehensive vulnerability management across heterogeneous environments, deeper vulnerability checks, and coverage beyond managed endpoints.
