In their own words
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.
Sirius
Sirius is an open-source vulnerability scanner for security teams that want operator control over discovery and triage. It combines network discovery, CVE detection, agent telemetry, and scanning through Nmap and Naabu. The Vulnerability Navigator provides severity groupings, CVSS-based filters, and export options; the Operator Console supports command execution, command history, and active-agent management. Dashboards show service health, infrastructure metrics, vulnerability trends, and centralized logs. Sirius can run in production or development mode through Docker Compose. Its listed minimum requirements are Docker Engine 20.10.0+ with Compose V2, 4 GB RAM, and 10 GB of free disk space. Supported host systems are Linux, macOS, and Windows through WSL2. REST endpoints on port 9001 use an API key, with documentation linking to an API reference and Go SDK. The Sirius Scan plan is free for self-hosted Docker use. Community support is available through Discord, GitHub Issues, and GitHub Discussions; the support page also describes enterprise priority support.
