Shodan
Community project
The original search engine for internet-connected devices, launched in 2009 by John Matherly and still famously accessible — a one-time membership fee unlocks most researcher features, with API subscriptions and the Shodan Monitor alerting service on top. The quickest way to see what an attacker sees about any organization's exposed services.

Capability checklist
ASM/BASHow Shodan measures up against the full Attack Surface Management & Breach/Attack Simulation taxonomy.
- External attack surface discovery — supported
- Continuously finds internet-facing assets, domains, and shadow IT before attackers do.
- Exposure prioritization — not supported
- Ranks discovered exposures using adversary and exploitability context.
- Breach and attack simulation — not supported
- Safely simulates real attack techniques against live defenses to test control effectiveness.
- Security control validation — not supported
- Measures whether existing tools actually detect or block the simulated attacks.
- Attack path mapping — not supported
- Shows the chained steps an attacker could take from an exposure to real impact.
- Continuous testing — not supported
- Re-runs simulations on a schedule to catch drift and regressions over time.
