Microsoft Defender External Attack Surface Management (EASM), built from RiskIQ technology, is Microsoft’s external attack surface management product for discovering and tracking internet-exposed assets. In this scope it focuses on outside-in visibility: finding unknown domains, hosts, IPs, certificates, SaaS and cloud resources, then identifying exposures such as misconfigurations and vulnerabilities. It is best suited for enterprises already using Microsoft security tooling, or teams that need continuous inventory of unmanaged external assets across hybrid and multi-cloud environments.
