What To Look For in an Attack Surface Management Solution

**Executive Summary:** This buyer's guide explains Attack Surface Management (ASM) as a continuous capability to discover and monitor internet-exposed assets (hosts, services, websites, storage buckets, cloud assets), prioritize security risks and compliance violations, and provide investigative and operational tooling; it contrasts ASM with pentests, VM, and cloud security products that lack holistic visibility and recommends ASM as essential for detecting unmanaged or misconfigured external assets to reduce breach risk and support compliance.
