Censys vs Rapid7: exposure management facts side by side
SHORT ANSWER
Censys describes 3 of the five tool types on the pages we read and Rapid7 describes 4; they differ on exposure management platforms. On proof, Censys describes exploitability checks but not attack-style testing and Rapid7 describes exploitability checks but not attack-style testing. We do not score either; the right choice depends on your estate, current platform, WAFs and capacity to fix.

What are the facts, side by side?
| Fact | Censys ASM | Rapid7 Surface Command |
|---|---|---|
| Positioning | Censys's external exposure management product, built on first-party scanning of all 65K ports and the Censys Internet Map. | Rapid7's attack surface product, combining external discovery (EASM) with a unified internal and external asset inventory (CAASM), part of the Rapid7 Command platform. |
| Deployment | Discovery expands from seeds the customer adds in the console or through the API; assets found beyond the seeds appear under a Found by Censys tab.
