Greenbone OpenVAS vs Microsoft Defender Vulnerability Management

Greenbone OpenVAS and Microsoft Defender Vulnerability Management are both open source vulnerability scanner solutions. Greenbone OpenVAS the most widely used open-source vulnerability scanner with 100,000+ network vulnerability tests, while Microsoft Defender Vulnerability Management microsoft's built-in vulnerability management integrated with Defender for Endpoint. The best choice depends on your organization's size, technical requirements, and budget.

Choose Greenbone OpenVAS if completely free with no licensing costs is your priority and security teams wanting a free, open-source vulnerability scanner with no licensing costs and full customization control. Choose Microsoft Defender Vulnerability Management if included with Microsoft Defender for Endpoint P2 at no additional cost matters most and microsoft-centric organizations wanting vulnerability management bundled with their existing Defender for Endpoint deployment.

Microsoft Defender Vulnerability Management starts at Included with Microsoft Defender for Endpoint P2 / Standalone add-on $3/user/month (per-user (monthly subscription, bundled with microsoft 365 e5)). Greenbone OpenVAS starts at Free (open source) / Greenbone Enterprise appliances from $5,000/year (open source with commercial appliance options). As always, the sticker price only tells part of the story. Factor in add-ons, implementation costs, and what's actually included at each tier.

It depends on how deeply Greenbone OpenVAS is embedded in your stack. Most teams run both in parallel for a few weeks before cutting over. Check whether Microsoft Defender Vulnerability Management supports importing your existing configs or policies. That's usually the biggest time sink.
