In this segment, we will explore some pretty awesome tools for scanning the Internet, with a focus on network edge devices. We'll bring it all together with Claude Code and look at some sample results. Tools include:

  • Shodan | Passive recon — query existing scan data for exposed devices, services, and vulns | Passive (API) | Instant (no packets sent)
  • ZMap | Host discovery — find live hosts with open ports | L4 (TCP SYN, UDP, ICMP) | Millions of packets/sec
  • ZGrab2 | Application-layer handshakes — grab banners, certs, headers | L7 (30+ protocol modules) | Thousands of hosts/sec
  • Nerva | Service fingerprinting — identify 140+ protocols with metadata, CPEs, technology stacks | L7 (TCP, UDP, SCTP) | Fast, concurrent
  • Nuclei | Template-based vulnerability scanning — default creds, exposed panels, known CVEs | L7 (HTTP, network) | Hundreds of targets/min
  • Shannon | Vulnerability exploitation — AI-powered whitebox pentesting of web apps | Application | ~1-1.5 hrs per target
  • edgescan.py | Automated pipeline — orchestrates all tools above into a single command | Orchestration | End-to-end
