CST Verdict

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

Yasuo

DevSecOps teams operating on minimal budgets will get real value from Yasuo because it does one thing well: finding vulnerable third-party web applications already sitting in your network, which most scanners miss or charge heavily for. The 573 GitHub stars and active Ruby community mean it's battle-tested enough for production use without licensing friction. Skip this if you need scanning for custom code or containerized applications; Yasuo is specifically built to hunt known exploits in off-the-shelf software, not your own vulnerabilities.
