Nmap vs NSAuditor AI

Nmap is a free, open-source utility for discovering networks and auditing security. It uses raw IP packets to identify available hosts, services and versions, operating systems, and packet filters or firewalls. Scanning options include TCP and UDP ports, OS and version detection, and ping sweeps. Network administrators can use it to inventory systems, plan service upgrades, and monitor host or service uptime. The Nmap Scripting Engine runs bundled or user-written scripts in parallel for networking tasks such as discovery and vulnerability checks. The suite also includes Zenmap, a graphical interface and results viewer; Ncat for data transfer and debugging; Ndiff for comparing scan results; and Nping for packet generation and response analysis. Most port-scan types require privileged access to send and receive raw packets, although unprivileged users can run connect and FTP bounce scans. Nmap is not a comprehensive vulnerability scanner. End-user use is free, but redistribution in commercial products requires an OEM license. Quarterly OEM licenses start at $9,980.00 per 3 months for eligible small or startup companies.

NSAuditor AI is an open-source network security scanner that runs on a customer’s infrastructure and can be configured to operate fully offline. It scans network hosts and CIDR subnets, AWS, Azure, GCP, TLS, DNS, and operational technology targets; authenticated and continuous scanning are supported. Community includes 27 scanner plugins, parallel subnet scanning, webhook alerts, and exports in JSON, HTML, SARIF, and CSV. AI analysis is available in every tier through OpenAI, Claude, or Ollama with customer-provided API keys. Pro adds offline-first NVD CVE matching and risk scoring. Enterprise adds cloud auditors and evidence packs for listed frameworks including SOC 2, HIPAA, PCI DSS v4.0.1, and ISO/IEC 27001:2022. The maker says scan data, findings, and reports remain on the customer’s machine, and license checks can work offline. Community costs nothing; Pro costs $39 a year or $49 a month. Enterprise plans cost $2,000 a year, $5,000 a year, or $10,000 a year. It supports Windows, macOS, and Linux.
