CyCognito vs Tenable ASM: exposure management facts side by side
SHORT ANSWER
CyCognito describes 5 of the five tool types on the pages we read and Tenable ASM describes 4; they differ on WAF posture. On proof, CyCognito describes attack-style testing and Tenable ASM 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.
