  • Passes discovered ports to Nmap for deeper analysis
Cons
  • Internet Scanner pricing varies by scan speed at $0.30 per kpps/month
  • Some advanced monitoring and scheduling capabilities require paid tiers
  • API base URLs are inconsistent and should be validated before integration
  • Command-line deployment requires terminal-based workflows
  • Windows use is documented through Docker rather than native support
  • Service and OS detection depend on Nmap passthrough
