NSAuditor AI vs OpenVAS

NSAuditor AI is an open-source network security scanner that runs on a customer’s infrastructure and can be configured to operate fully offline. It scans network hosts and CIDR subnets, AWS, Azure, GCP, TLS, DNS, and operational technology targets; authenticated and continuous scanning are supported. Community includes 27 scanner plugins, parallel subnet scanning, webhook alerts, and exports in JSON, HTML, SARIF, and CSV. AI analysis is available in every tier through OpenAI, Claude, or Ollama with customer-provided API keys. Pro adds offline-first NVD CVE matching and risk scoring. Enterprise adds cloud auditors and evidence packs for listed frameworks including SOC 2, HIPAA, PCI DSS v4.0.1, and ISO/IEC 27001:2022. The maker says scan data, findings, and reports remain on the customer’s machine, and license checks can work offline. Community costs nothing; Pro costs $39 a year or $49 a month. Enterprise plans cost $2,000 a year, $5,000 a year, or $10,000 a year. It supports Windows, macOS, and Linux.

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.
