EXTERNAL ATTACK SURFACE MANAGEMENT (EASM) BUYER'S GUIDE

Summary from the TLDR InfoSec newsletter

External Attack Surface Management (EASM) tools automate the discovery and continuous monitoring of internet-facing assets, providing organizations with an attacker's perspective of their vulnerabilities across domains, IP addresses, and exposed services. The strategic value lies in combining automated asset discovery with risk prioritization—EASM products excel at identifying shadow IT, abandoned subdomains, and misconfigurations that traditional internal scanning misses. Organizations should select EASM solutions based on their specific needs: small businesses require clear remediation guidance, SMEs need robust subdomain discovery to prevent takeovers, and enterprises benefit from large-scale IP scanning with export capabilities for distributed security teams.
