Zeek is a powerful network analysis framework that is much different from the typical IDS you may know.

Network recon framework. Build your own, self-hosted and fully-controlled alternatives to Shodan / ZoomEye / Censys and GreyNoise, run your Passive DNS service, build your taylor-made EASM tool, collect and analyse network intelligence from your sensors, and much more! Uses Nmap, Masscan, Zeek, p0f, ProjectDiscovery tools, etc.
