| Integrations | For OEM integration, the project recommends running Nmap and parsing its XML-formatted output, and also permits other approaches such as parsing normal output or processing its data files. | The latest release lists SARIF and DefectDojo-compatible reports, and the project supports Maltego transforms. |
| Purpose | Nmap is a free and open-source utility for network discovery and security auditing. | Automates information gathering, vulnerability scanning, and penetration testing, including discovery of open ports, services, misconfigurations, default credentials, and subdomains. |
| Scanning | Nmap supports TCP and UDP port scanning, OS detection, version detection, and ping sweeps. | Its modular architecture supports prebuilt and customizable modules for different scanning tasks. |
| Support | The free version has no warranty and is supported by a community, while active OEM maintenance subscriptions include commercial technical support. | The security policy points users to GitHub Issues and the OWASP Slack #project-nettacker channel for general inquiries. |

In their own words
Nmap
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.
OWASP Nettacker
OWASP Nettacker is free, open-source software for automating information gathering, vulnerability scanning, and penetration testing. It discovers open ports, services, misconfigurations, default credentials, and subdomains across IPv4 addresses, ranges, CIDR blocks, domains, and HTTP or HTTPS URLs. Users can run it as a command-line utility, Docker container, API, or Web GUI. A modular architecture provides prebuilt and customizable scanning modules. Reports are generated in HTML, TXT, JSON, and CSV, with the latest release listing SARIF and DefectDojo-compatible output; Maltego transforms are supported. Nettacker is written entirely in Python and does not launch external tools. Installation options include Poetry from source, pip or pipx from PyPI, and Docker. Native support covers Linux, macOS, and FreeBSD; Docker serves other operating systems while native Windows support is in progress. The installation guide currently supports Python 3.11–3.12, with later compatibility underway. Security updates cover the latest stable release and current master branch, while older versions may not receive updates. The project directs vulnerability reports through a private GitHub Security Advisory.
