help OpenVAS FAQ

What is the relationship between OpenVAS and Greenbone Vulnerability Management?

OpenVAS is the scanning engine within the broader Greenbone vulnerability-management ecosystem. The surrounding Greenbone components handle tasks such as targets, schedules, feeds, reports, and the web interface.

Is OpenVAS still open source and free?

Greenbone provides an OpenVAS Community Edition with open-source components and the Community Feed. Commercial OPENVAS products add enterprise feeds, appliances, support, and other managed capabilities.

How does OpenVAS find newly disclosed vulnerabilities?

The scanner executes Vulnerability Tests supplied through a Greenbone feed containing security information such as CVEs and scan configurations. Greenbone states that the community test feed receives daily updates.

How does OpenVAS compare with Nessus?

Both scan hosts and network services for known vulnerabilities, and OpenVAS originated after Nessus stopped being fully open source. OpenVAS favors a self-managed open-source stack, while Tenable sells Nessus as a proprietary product with commercial support and its own plugin feed.
