CST VerdictBased on our analysis of NIST CSF 2.0 coverage, company size fit, deployment model, here is our conclusion:
Penetration testers running internal security assessments on smaller networks will benefit from Legion's automated reconnaissance pipeline, which compresses hours of manual scanning into minutes without licensing friction. The 1,052 GitHub stars and active open source community signal production-grade stability for teams already comfortable maintaining their own tools. Skip Legion if your organization needs commercial support, reporting that maps to compliance frameworks, or scanning at scale across hundreds of hosts; you'll spend more time patching gaps than testing.
