CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, 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.
Core Security Outflank Security Tooling
Mid-market and enterprise red teams will find Outflank Security Tooling essential for testing EDR bypass at scale; its steganography-based payload concealment and unpublished EDR evasion techniques let operators validate detection gaps that commodity toolkits can't expose. The continuous operator documentation and Cobalt Strike integration mean your team stays current as vendors patch, and on-premises deployment keeps artifacts off shared infrastructure. Skip this if your mandate is offensive security without a specific EDR validation requirement; Outflank assumes you're already comfortable with advanced post-exploitation and are hunting for the gaps most red teams never find.
