CST VerdictBased on our analysis of available product data, here is our conclusion:
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.
