Netz
Discover internet-wide misconfigurations in services like Elasticsearch, databases, and web servers using high-speed scanning tools.
What is Netz?
Netz is an open-source security tool that scans the entire internet to discover misconfigured services like Elasticsearch, databases, and web servers that are publicly accessible without authentication. It combines masscan for rapid port scanning and zgrab2 for application-layer probing to identify vulnerable assets efficiently. The project addresses the critical need for organizations to verify their external exposure and prevent accidental data leaks.
Security researchers, penetration testers, and DevOps engineers responsible for assessing external attack surfaces and ensuring services are not inadvertently exposed. It's also suitable for red teams conducting reconnaissance and blue teams validating security controls.
Netz offers a high-performance, self-hosted alternative to commercial scanners like Shodan, with the flexibility to run on custom infrastructure and scan specific protocols. Its unique selling point is the ability to achieve internet-wide scans in minutes using PF_RING ZC and cloud automation, providing granular control over scanning parameters.
