Security teams with limited budgets who can tolerate manual tuning will find OpenVAS valuable for network-wide vulnerability discovery at zero cost. It runs on commodity hardware, covers CVSS scoring across 200,000+ known vulnerabilities, and integrates with Greenbone's commercial support if you need it later. Skip this if your organization lacks Linux administration depth or expects a polished UI and hands-off updates; OpenVAS demands configuration discipline and prioritizes breadth of scanning over ease of operation.
