Identify 170+ network protocols across TCP, UDP, and SCTP transports with rich metadata extraction. Nerva rapidly detects and identifies services running on open network ports. Use it alongside port scanners like Naabu to fingerprint discovered services, or integrate it into your security pipelines for automated reconnaissance. Features - 170+ Protocol Plugins — Databases, remote access, web services, messaging, industrial, and telecom protocols - 76 HTTP Fingerprinters — Detect web technologies including firewalls, databases, AI/LLM servers, and more - Security Misconfiguration Detection — Identify common security issues like unauthenticated APIs and cleartext protocols ( --misconfigs ) - Multi-Transport Support — TCP (default), UDP ( --udp ), and SCTP ( --sctp , Linux only) - Proxy Support — Route scanning traffic transparently through SOCKS5 or HTTP proxies with configurable DNS resolution - Rich Metadata — Extract versions, configurations, and security-relevant details from each service - Fast Mode — Scan only default ports for rapid reconnaissance ( --fast ) - Flexible Output — JSON, CSV, or human-readable formats - Pipeline Friendly — Pipe from Naabu, Nmap, or any tool that outputs host:port - Go Library — Import directly into your Go applications Installation Releases Downlo","default_branch":null,"files":null,"tree":[],"storefront":"/r/praetorian-inc","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/praetorian-inc/nerva/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
