- 4x fewer stale or duplicate results
- 7x faster discovery of infrastructure changes
Censys is THE Authority for Internet Intelligence
Censys captures 8x more services than Shodan across the complete 65K port space. Non-Standard and high number ports commonly are exploited by attackers and the source of Shadow IT so you need to see it all.
With Censys, 92% of listed services are live, compared to just 68% in Shodan. The internet evolves quickly. Stale or duplicate data creates noise, false positives, and worse, a false sense of security.
Censys detects new services in <24 hours whereas Shodan requires ~3 days. Services appear and disappear quickly so fast discovery is critical to minimize risk.
