NSAuditor AI vs ShadowSecurityScanner

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.

ShadowSecurityScanner is a free, open-source desktop tool for penetration testing and network vulnerability scanning on Windows, macOS, and Linux. It scans network hosts, servers, web applications, and network appliances using port checks, service and operating-system fingerprinting, and thousands of active security tests. Findings receive FIRST.org EPSS scores and are checked against the CISA Known Exploited Vulnerabilities catalog. Scan comparisons identify findings that are new, regressed, or resolved. Reports can be exported as PDF, HTML, SARIF, XML, or CSV, with SARIF described as suitable for GitHub code scanning. A signed update feed refreshes the audit catalog with daily CISA KEV updates, Nuclei, and curated advisories. The application runs locally, stores its database in the user profile, and has no cloud component or telemetry. It is distributed as one self-contained app, without agents or a database server. Listed requirements include Windows 10/11, macOS 11 or later on Apple Silicon, and Linux x64 or ARM64. Use is limited to authorized testing; denial-of-service tests are excluded.
