CST Verdict

Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:

surf

Cloud security teams running penetration tests against their own infrastructure will get the most from surf; it cuts through the noise of host enumeration by automatically filtering for SSRF-exploitable targets, saving hours of manual candidate vetting. The 670 GitHub stars and free pricing mean you can validate this against your own cloud ranges before committing headcount. Not the right fit if you need a full pentest platform with payload generation, reporting, and remediation workflows; surf does one job well and leaves the rest to you.
