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

Questions readers ask
Is Censys or Cortex Xpanse better?
Neither is scored on this site. Censys describes 3 of five tool types and Cortex Xpanse 3 on the pages we read, and they differ on 6 recorded facts. Which fits depends on your estate, current platform, need for proof, WAFs and capacity to fix; the finder checks those.
Which of the two proves exploitability?
Censys: exploitability checked: Partly; attack-style testing: Not in our sources. Cortex Xpanse: exploitability checked: Not in our sources; attack-style testing: Not in our sources.
Do Censys or Cortex Xpanse publish prices?
Censys: ASM: contact sales. A free Censys platform account exists, and credits start at $100. Cortex Xpanse: Not published by Palo Alto Networks. Reseller listing (UK G-Cloud 14, KHIPU Networks): £70,850.84 an instance a year, no free trial, public-facing attack surfaces only.
