Attack Surface Tools FAQ
Common questions about Attack Surface tools, selection guides, pricing, and comparisons.
Attack surface management (ASM) is the continuous discovery, inventory, classification, and monitoring of all internet-facing assets that could be exploited by attackers. This includes domains, subdomains, IP addresses, cloud resources, APIs, web applications, and third-party services. ASM tools automatically find assets you may not know about, including shadow IT and forgotten infrastructure.
External Attack Surface Management (EASM) focuses on discovering and monitoring internet-facing assets from an outside-in perspective, simulating what an attacker would see. Cyber Asset Attack Surface Management (CAASM) provides an inside-out view by aggregating data from internal security tools (EDR, vulnerability scanners, CMDB) to create a comprehensive asset inventory. Most organizations benefit from both approaches.
Vulnerability scanning tests known assets for specific CVEs and misconfigurations. Attack surface management first discovers all assets (including unknown ones), then continuously monitors for exposure changes like new subdomains, exposed services, expired certificates, and cloud misconfigurations. ASM answers "what do I have?" while vulnerability scanning answers "what is wrong with what I know about?"
Yes. Out of 24 attack surface tools listed on CybersecTools, 2 are free and 22 are commercial. Free tools work well for small teams, testing, and budget-conscious organizations. Commercial tools typically add enterprise features, dedicated support, and SLA guarantees.
