Attack Surface Management (ASM) tools often focus on asset discovery, leading to increased visibility but not necessarily reduced risk or incidents. Organizations frequently measure ASM success by asset counts rather than evaluating actual risk reduction, creating a gap between effort and outcome. Effective ASM requires shifting focus from asset visibility to metrics that measure response quality and exposure duration. Key outcome metrics include mean time to asset ownership, reduction in unauthenticated endpoints, and time to decommission assets after ownership loss. Without outcome-oriented measurements, ASM struggles to justify budgets, as visibility alone does not confirm reduced exposure or improved security posture. A practical approach involves making asset visibility accessible across teams to enhance resolution speed without increasing alert volume. Sprocket Security suggests that real ASM success is demonstrated by faster resolution of risky assets and reduced exposure duration, not just asset inventory growth.
