Nuclei vs Greenbone OpenVAS

Greenbone OpenVAS and Nuclei are both open source vulnerability scanner solutions. Greenbone OpenVAS the most widely used open-source vulnerability scanner with 100,000+ network vulnerability tests, while Nuclei fast, template-based open-source vulnerability scanner with 8,000+ community-contributed detection templates. 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 Nuclei if extremely fast scanning with Go-based concurrent execution matters most and security teams and researchers wanting a fast, customizable, template-driven vulnerability scanner for web and infrastructure testing.

Greenbone OpenVAS starts at Free (open source) / Greenbone Enterprise appliances from $5,000/year (open source with commercial appliance options). Nuclei starts at Free (open source) / ProjectDiscovery Cloud Platform from $100/month (open source with optional cloud platform). 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 Nuclei is embedded in your stack. Most teams run both in parallel for a few weeks before cutting over. Check whether Greenbone OpenVAS supports importing your existing configs or policies. That's usually the biggest time sink.
