EASM (External Attack Surface Management)
A specialized approach to discovering and monitoring an organization's externally exposed assets, services, and vulnerabilities from an attacker's perspective.
External Attack Surface Management (EASM) is a subset of attack surface management focused specifically on internet-facing assets visible to external attackers. EASM platforms continuously discover and monitor an organization's external digital footprint — including forgotten subdomains, exposed cloud storage, leaked credentials, misconfigured services, and certificate issues — without requiring internal access or agent installation.
EASM has emerged as a distinct category because the external attack surface is where most attacks begin. Organizations often have assets they've lost track of — legacy applications, developer test environments, acquired company infrastructure, or cloud resources created outside IT governance. EASM tools use techniques similar to what attackers use: DNS enumeration, certificate transparency log analysis, port scanning, and web crawling.
How APVISO helps with this: APVISO complements EASM tools by going beyond discovery to active exploitation testing. While EASM platforms identify your exposed assets, APVISO's AI agents actively test those assets for exploitable vulnerabilities — turning passive asset inventory into actionable security intelligence.
