Shodan vs Pentesting.se

Shodan is an internet-wide search engine that indexes exposed services, banners, and device metadata. It is a powerful passive recon tool for security researchers. Pentesting.se actively scans assets you own, tracks changes over time, and gives you prioritised findings with remediation steps.

What Shodan does well

  • Broad internet-scale passive scanning and indexing
  • Discovering exposed industrial control systems and IoT devices
  • Research and threat intelligence use cases
  • API access for integration into security tooling
Key difference: Shodan shows you what is already indexed on the internet — data that may be days or weeks old. Pentesting.se actively scans on your schedule and alerts you to new findings, changed headers, expired certificates, or newly discovered subdomains in near real-time.
