NSAuditor AI review
A local-first scanner with open-source access, AI analysis, and compliance-focused tiers.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
NSAuditor AI is an open-core vulnerability and network security auditing platform for security teams, MSPs, MSSPs, and compliance consultancies. It scans network hosts and CIDR subnets, audits AWS, Azure, and GCP environments, matches findings to CVEs, prioritizes risk, maps findings to MITRE ATT&CK, and exports JSON, HTML, SARIF, CSV, and Markdown reports. Windows, macOS, and Linux are supported, and the software runs on customer infrastructure rather than as a SaaS service.
The plan structure separates core scanning from deeper vulnerability intelligence and enterprise controls. Community includes 27 scanner plugins, subnet scanning, AI analysis with OpenAI, Claude, or Ollama, CTEM watch mode, webhook alerts, and multiple export formats. Pro Annual and Pro Monthly add offline CVE matching, MITRE ATT&CK annotations, risk scoring, exploit intelligence using CISA KEV and FIRST EPSS, compliance reports, and unlimited CTEM history. Enterprise Base, Growth, and Scale provide 56 scanner plugins, eight compliance evidence frameworks, air-gapped operation, zero data exfiltration, and a dedicated support channel. Growth adds custom compliance-mapping help, while Scale adds custom plugins.
NSAuditor AI fits teams that need local operation, continuous monitoring, cloud auditing, and compliance workflows in one tool. Its connectors for Vanta, Drata, and Secureframe support compliance-oriented workflows, while MCP client support and the OpenAI, Claude, and Ollama integrations extend analysis options. The main tradeoff is deployment responsibility: cloud auditing depends on customer-configured credentials, and the strongest compliance, support, and customization features sit in Enterprise tiers. Choose it for open-source, on-premises scanning with air-gapped and offline capabilities; choose an alternative if a fully managed SaaS scanner is the priority.
