Quick Answer
Microsoft Defender Vulnerability Management pricing in 2026 has three tiers: Standalone at $3 per user per month, Add-on for Defender for Endpoint P2 customers at $2 per user per month, and included free with Microsoft 365 E5 and Defender for Cloud. The median Defender Vulnerability Management contract sits at $149 per year per Vendr. The Add-on tier covers Windows, macOS, Linux, iOS, Android, and containers (Microsoft + CostBench, September 2026).
Defender Vulnerability Management is the cost-leader in the vulnerability management category for organizations already standardized on Microsoft 365. It is included free with E5.

Defender Vulnerability Management tiers and what each includes
Microsoft sells Defender Vulnerability Management in three configurations keyed to existing customer entitlements. The Standalone tier at $3 per user per month is for organizations new to Microsoft Defender, or those running Defender for Endpoint P1 or Microsoft 365 E3, who want comprehensive vulnerability management without committing to the full Defender for Endpoint P2 EDR upgrade. The Add-on tier at $2 per user per month is for organizations already running Defender for Endpoint P2 (which ships with M365 E5). The third configuration is included free with Microsoft 365 E5 and Defender for Cloud (Microsoft Defender pricing page, September 2026).
| Tier | Best fit | Main capabilities | List price |
|---|---|---|---|
| Standalone | Defender for Endpoint P1 or M365 E3 customers seeking VM | Asset inventory, vulnerability assessment, configuration assessment, continuous monitoring | $3 per user per month |
| Add-on for Defender for Endpoint P2 | M365 E5 customers seeking enhanced VM integration | Everything in Standalone plus enhanced P2 integration, automated investigation and response, attack surface reduction rules, advanced threat hunting, EDR correlation, Sentinel integration, priority support | $2 per user per month |
| Included | M365 E5 or Defender for Cloud customers | Equivalent to Standalone functionality | Free (bundled) |
The Add-on tier unlocks the integration that justifies the $2 per user per month premium for existing Defender for Endpoint P2 customers. Automated investigation and response correlates vulnerability findings with EDR detections, attack surface reduction rules, and threat hunting signals. Microsoft Sentinel integration makes Defender Vulnerability Management findings available for SIEM correlation in the unified security operations stack. Custom detection rules and priority support complete the premium bundle (CostBench, August 2026).
Cross-platform and container coverage
Defender Vulnerability Management is broader than most dedicated vulnerability management platforms. The platform supports Windows, macOS, Linux, iOS, and Android endpoints through the Microsoft Defender for Endpoint agent. The recent expansion adds vulnerability assessments of containers, providing coverage for Kubernetes and Docker workloads through integration with Microsoft Defender for Cloud (Microsoft Defender, September 2026).
Cross-platform coverage matters because most enterprise environments now span workstations, servers, mobile devices, and cloud workloads. Dedicated vulnerability management platforms (Tenable, Qualys, Rapid7) typically focus on servers and workstations; container vulnerability assessment usually requires a separate add-on product (Prisma Cloud, Wiz, or Defender for Containers). Defender Vulnerability Management bundles workstation plus server plus mobile plus container coverage into a single per-user subscription, which is structurally simpler than the multi-product approach used by dedicated VM vendors (CostBench, August 2026).
Cost comparison against dedicated vulnerability management platforms
Defender Vulnerability Management is structurally cheaper for Microsoft 365 shops. The Standalone tier at $3 per user per month equals $36 per user per year. The Add-on tier at $2 per user per month equals $24 per user per year, which is less than Tenable Vulnerability Management's $26 to $38 per asset per year and dramatically less than Qualys VMDR's $199 to $250 per asset per year (Microsoft + Ciphers Security, September 2026).
| Platform | Pricing model | Typical 2026 rate |
|---|---|---|
| Defender Vulnerability Management (Add-on) | Per user per year | $24 |
| Defender Vulnerability Management (Standalone) | Per user per year | $36 |
| Defender Vulnerability Management with M365 E5 | Per user per year | $0 (included) |
| Rapid7 InsightVM | Per asset per year | $19 to $23 |
| Tenable Vulnerability Management | Per asset per year | $26 to $38 |
| Qualys VMDR | Per asset per year | $199 to $250 |
The cost advantage narrows when comparing Defender Vulnerability Management to dedicated platforms on a per-asset basis (defender is per-user, dedicated VM is per-asset; each user may cover multiple devices or vice versa). For a 500-endpoint environment with 250 users (each user averaging 2 devices), Defender Vulnerability Management Add-on at $250 × 24 = $6,000 per year is dramatically less than Tenable VM at 500 × $30 = $15,000 or Qualys VMDR at 500 × $200 = $100,000. For organizations outside the Microsoft ecosystem, dedicated platforms offer deeper vulnerability research and broader CVE coverage (CostBench, August 2026).
When to choose Defender VM over dedicated platforms
Defender Vulnerability Management is the right choice in three scenarios. First, when the organization is standardized on Microsoft 365 E5 and gets vulnerability management as part of the bundle at zero incremental cost. Second, when the organization already runs Defender for Endpoint P2 and wants an integrated EDR-vulnerability management stack without third-party integration overhead. Third, when the asset scope is primarily endpoints plus Azure workloads, which Defender covers natively. The dedicated platforms (Tenable, Qualys, Rapid7) make more sense for organizations with substantial non-Microsoft footprint, network devices, OT systems, or compliance programs that require dedicated vulnerability research depth (Microsoft Defender, September 2026).
The single most important procurement decision is to assess whether the existing Microsoft footprint already includes the relevant entitlements. Organizations on M365 E3 can upgrade to the Standalone tier at $3 per user per month, but the cost-effective path is to negotiate an upgrade to E5 if the broader Microsoft 365 suite is needed anyway. The cost math changes once E5 is in scope because vulnerability management becomes effectively free (CostBench, August 2026).
