Cortex Xpanse vs watchTowr: exposure management facts side by side
SHORT ANSWER
Cortex Xpanse describes 3 of the five tool types on the pages we read and watchTowr describes 5; they differ on exposure validation and WAF posture. On proof, Cortex Xpanse does not describe exploit testing on the pages we read and watchTowr describes attack-style testing. We do not score either; the right choice depends on your estate, current platform, WAFs and capacity to fix.
