IVRE (Instrument de veille sur les réseaux extérieurs) is a framework for network recon. Build your own, self-hosted and fully-controlled alternatives to Shodan / ZoomEye / Censys and GreyNoise, run your Passive DNS service, collect and analyse network intelligence from your sensors, and more.
It relies on open-source well-known tools (Nmap, Masscan, ZGrab2, ZDNS and Zeek (Bro)) to gather data (network intelligence), stores it in a database (MongoDB is the recommended backend), and provides tools to analyze it.
It includes a Web interface aimed at analyzing Nmap scan results (since it relies on a database, it can be much more efficient with huge scans than a tool like Zenmap, the Nmap GUI, for example).
This is free and open source software.
