CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Penetration testers and red teamers running internal security assessments need Whonow because DNS Rebinding attacks are nearly impossible to execute manually and this tool removes that friction entirely. The free pricing and 654 GitHub stars signal active adoption among practitioners who've validated the technique works against real same-origin policy implementations in air-gapped testing. Skip this if your team lacks the network access or authorization to run active DNS manipulation; Whonow is a surgical instrument for controlled lab and authorized internal assessments, not a passive reconnaissance tool.
