What Is Shodan?
Shodan is a search engine for internet-connected devices and services. It indexes exposed servers, cameras, routers, industrial systems, databases, banners and other public-facing infrastructure.
Honest Review
Shodan is powerful for cybersecurity research and attack-surface discovery. It can quickly show what services are exposed online and help defenders find risky assets before attackers do.
The limitation is that Shodan requires responsible use. It should be used for defensive research and authorized assessment, not probing systems you do not own. Free access is useful but limited.
RadarScore reasoning: Quality is strong for internet asset discovery. Value is good for security users. Ease of use is lower because queries and interpretation require skill. Free-tier quality is limited but useful. Support is better on paid plans.
