CST Verdict

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

Libnet

Network penetration testers and red teamers need Libnet for packet crafting that doesn't require context-switching between tools; the 956 GitHub stars reflect sustained adoption among practitioners who value a lightweight API over monolithic frameworks. Its simplicity means you're writing exploit code faster than frameworks that bundle unnecessary abstraction layers, though you'll need to handle payload validation yourself rather than relying on built-in guardrails. Skip this if your team prefers GUI-driven traffic generation or needs extensive logging and compliance reporting baked in.
