CST VerdictBased on our analysis of available product data, here is our conclusion:
Security teams building reconnaissance automation into their reconnaissance workflow should start with Amass because it outperforms commercial tools at subdomain enumeration speed and catches assets that paid solutions miss through its multi-source passive collection approach. The 14,260 GitHub stars reflect sustained adoption by practitioners who've validated it against their own external asset inventories. Skip this if you need managed threat intelligence feeds, API-based asset tagging, or risk scoring; Amass is a discovery engine, not an asset management platform.
Small security teams and pentesters who need fast subdomain enumeration without vendor lock-in should start with Findomain; its free pricing and 3,561 GitHub stars mean you get active community validation without seat licensing friction. The tool handles passive reconnaissance across multiple data sources and integrates notifications directly into your workflow, covering the Identify function of NIST CSF 2.0 with minimal setup. Skip this if you need active vulnerability scanning or remediation tracking; Findomain discovers the attack surface but doesn't tell you what's actually vulnerable on it.
