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.
Penetration testers and red teamers targeting Microsoft environments need Ruler for its direct Exchange server manipulation and Outlook client exploitation capabilities; it's the fastest way to validate post-compromise persistence and lateral movement through mail infrastructure. The tool's 2,259 GitHub stars and active maintenance reflect real adoption in adversary simulation workflows where native Microsoft protocol abuse matters more than GUI polish. Skip this if your team needs detection tuning or defensive guidance; Ruler is purely offensive and assumes you already have Exchange access to exploit.
