The open-source network vulnerability scanner
OpenVAS is an open-source vulnerability scanner that also goes by Greenbone Community Edition and GVM (Greenbone is the lead maintainer).
OpenVAS tests servers and other network-connected devices with tens of thousands of vulnerability tests in the Greenbone Community Feed, synced daily. This can be done over the internet for publicly exposed systems or over private networks. The scanner first conducts a port scan of every IANA-registered TCP port and the top 100 UDP ports to discover what services are open. It then performs additional fingerprinting and testing to check for CVEs, insecure configurations, and vulnerable outdated software versions.
How to get the best scan results with OpenVAS
Update the vulnerability feed:
OpenVAS uses the Greenbone Community Feed as its source of vulnerability data. Ensure the feed is updated in your installation before starting a scan, so that all of the latest vulnerabilities are tested. Or use a managed service, such as HostedScan, which is updated daily.
Choose the right Quality of Detection (QoD):
QoD is a measure of the reliability of vulnerability tests. The default OpenVAS QoD is 70%. However, that may not be right for all systems. Read our guide to setting the right QoD.
Use the Consider Alive setting:
To optimize speed, OpenVAS will first send a ping request to each target and skip targets which do not respond. While this can save considerable time for very large address spaces, when scanning smaller sets of targets it is better to be thorough, as not all targets may respond to ping. Using HostedScan, targets are always considered alive and scanned fully.
OpenVAS runs tens of thousands of vulnerability tests.
From thousands of CVEs in the feed, these are the ones that show up most in real-world scans.

Benefits of using HostedScan
What HostedScan adds to OpenVAS
Mitigate security vulnerabilities
Discover CVEs, OWASP Top 10 vulnerabilities, and exploitable weaknesses across your entire infrastructure. Get prioritized remediation guidance with CVSS scoring and actionable risk classifications. Fix what matters first.
Manage your risk exposure
With regulations such as GDPR and CCPA, failure to maintain reasonable security procedures is grounds for lawsuits and fines.
Meet compliance requirements
Vulnerability scanning is essential for your compliance with SOC 2, ISO 27001, cyber insurance, and more.
Detect misconfigurations
90% of cyber attacks exploit simple misconfigurations, not zero-days. Detect exposed ports, weak credentials, outdated software, and common security gaps before attackers do: automatically, every day.
Map your attack surface
Your infrastructure changes constantly. Automatically discover and monitor all websites, servers, networks, and APIs, maintaining complete visibility of your attack surface without manual tracking.
