CST VerdictBased on our analysis of available product data, here is our conclusion:
Red teamers and penetration testers who need to build custom attack chains will find Impacket indispensable; its Python-native SMB, Kerberos, and NTLM implementations let you craft protocol-level attacks that commercial tools either can't do or won't let you customize. The 14,800+ GitHub stars reflect real adoption in offensive engagements, and the library's low-level protocol handling means you can exploit edge cases that signature-based defenses miss. Skip this if your team wants a point-and-click interface; Impacket demands Python fluency and assumes you understand the protocols you're weaponizing.
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.
