NSAuditor AI vs Nuclei

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.

Nuclei is a free, open-source vulnerability scanner for applications, infrastructure, cloud platforms, and networks. It uses YAML templates to define checks, drawing on more than 6,500 community-contributed templates; users can also create custom templates. Bulk and parallel scans, multiple target formats, and inclusion and exclusion filters are supported. Modules cover HTTP, DNS, TCP, headless, JavaScript, code, and file scanning, and authentication options include HTTP basic authentication and JWT. Nuclei can run in CI/CD pipelines, including through GitHub Actions, and export SARIF results to GitHub Code Scanning. It is distributed under the MIT License and is primarily a standalone CLI tool, with installation options including Go, Homebrew, Docker, GitHub, downloadable binaries, and Helm. It is actively developed, but has no LTS or stable version, so updates may bring breaking changes. Some templates can fuzz or take actions that risk denial of service; these are tagged and excluded from default scans. The tool is intended for security engineers, analysts, red teams, DevOps teams, bug bounty hunters, and penetration testers.
