CST VerdictBased on our analysis of available product data, here is our conclusion:
Red teams executing multi-platform campaigns will value CrossC2 for doing one thing exceptionally well: extending Cobalt Strike's command-and-control infrastructure to Linux and macOS without rebuilding your entire operational toolkit. The 2,546 GitHub stars and active maintenance signal a tool that actually works in production red team environments, not just in labs. Skip this if your operations are Windows-only or if you need post-exploitation capabilities beyond payload delivery; CrossC2 is strictly a C2 extender, not a replacement framework.
Penetration testers running red team engagements on tight budgets should reach for Social-Engineer Toolkit first; it's the fastest way to spin up custom phishing and credential harvesting attacks without writing payloads from scratch. The 12,355 GitHub stars reflect actual adoption among practitioners, and the framework's modularity lets you chain attacks that most commercial tools won't support. Skip this if your team needs post-exploitation stability or operator-friendly logging; SET is a craftsperson's tool that rewards scripting skill and tolerates rough edges.
