CrowdStrike EASM vs Defender EASM: exposure management facts side by side
SHORT ANSWER
CrowdStrike EASM describes 3 of the five tool types on the pages we read and Defender EASM describes 2; they differ on exposure management platforms. On proof, CrowdStrike EASM does not describe exploit testing on the pages we read and Defender EASM 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.
