NSAuditor AI vs OpenVAS

NSAuditor AI is an open-core network security audit platform that runs on customer infrastructure across Windows, macOS and Linux. Its agentless scans read configuration and metadata without requiring create, write, modify or delete permissions. The product supports air-gapped environments, offline licensing and zero-data-exfiltration operation. All tiers support AI analysis with OpenAI, Claude or Ollama using customer-provided API keys. Reports can be exported in formats including JSON, HTML, SARIF, CSV and Markdown, depending on edition. Pro adds offline NVD CVE matching and exploit-first prioritization using CISA KEV and FIRST EPSS data from customer-populated stores. Enterprise provides 28 cloud auditors across AWS, GCP and Azure, and maps scans to eight compliance frameworks. Community is free; Pro is listed at $39 a year or $49 a month. Enterprise plans cost $2000.00, $5000.00 or $10,000 a year. Community support is self-serve, while paid tiers add email, onboarding or dedicated support options.

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.
