OpenVAS vs Tenable Nessus

OPENVAS is a vulnerability scanner for identifying weaknesses in IT systems. It supports authenticated and unauthenticated testing across internet and industrial protocols, with performance tuning for large scans, and uses a vulnerability-test feed updated daily. The commercial OPENVAS SCAN product checks network services, servers, applications, container images, and authenticated endpoints for vulnerabilities, misconfigurations, and missing patches. It is offered as hardware or virtual appliances and can run entirely inside a customer's environment. Listed integrations include ServiceNow, Splunk, Nagios, Sourcefire, and CyberArk. OPENVAS FREE is a cross-platform virtual appliance intended for private use and non-professional IT infrastructures. It uses the Community Feed, cannot update itself, and lacks schedules, notifications, integrated backups, and air-gap support. The free edition has no default enterprise support, and its self-signed TLS certificate requires a browser exception. OPENVAS BASIC costs €2,524 a year; it excludes API access, sensors, remediation tickets, and Greenbone Support. OPENVAS SCAN pricing is by quote.
