NSAuditor AI review
A self-hosted, open-source scanner with broad discovery and compliance reporting.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
NSAuditor AI is an open-core, self-hosted network security audit platform for security teams, IT administrators, and organizations that need local or air-gapped assessment. It discovers network hosts and services, runs non-destructive vulnerability probes, matches findings against offline CVE data, maps issues to MITRE ATT&CK, and produces reports and compliance evidence. Community Edition is available on Windows, macOS, and Linux, making the product a fit for teams that prefer customer-controlled deployment over a SaaS scanner.
Pricing divides the product into Community, Pro, and Enterprise editions. Community Edition is free and includes 27 scanner plugins, subnet scanning, AI analysis, CTEM watch mode, webhook alerts, and JSON, HTML, SARIF, and CSV exports. Pro adds offline CVE matching, MITRE ATT&CK technique annotations, risk scoring and prioritization, compliance reports, Advanced CTEM, and email support at $470 per year or $49 per month. Enterprise starts at $2,000 per year and adds 56 plugins, eight-framework compliance, cloud auditing across AWS, Azure, and Google Cloud, GRC connectors, air-gapped operation, and a dedicated support channel. Enterprise Growth and Enterprise Scale add priority response, custom compliance-mapping help, unlimited seats, custom SLAs, custom plugins, and dedicated support options at $5,000 and $10,000 per year respectively.
Its ecosystem covers OpenAI, Claude, Ollama, Vanta, Drata, and Secureframe, while reporting supports Markdown alongside JSON, HTML, SARIF, and CSV. The product also includes subnet and SYN scanning, CTEM watch mode, webhook alerts, and credentialed scans without agent-based scanning. That breadth suits teams seeking discovery, evidence, and local operation in one tool. Smaller teams may find Community Edition sufficient; organizations needing advanced prioritization, cloud auditing, GRC connections, or dedicated support should consider the paid tiers.
