Based 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.
Red teamers and penetration testers running Windows infrastructure assessments will get the most from Seatbelt because it executes extensive host reconnaissance in minutes without requiring elevated privileges or agent deployment. With 4,500+ GitHub stars and active community contributions, it's battle-tested across thousands of engagements and remains the fastest way to surface misconfigurations, missing patches, and weak credential storage on Windows systems. Skip this if you need cross-platform coverage or post-exploitation payload delivery; Seatbelt is reconnaissance-only and Windows-native, which is exactly why it's good at what it does.
