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Outflank Security Tooling essential for testing EDR bypass at scale; its steganography-based payload concealment and unpublished EDR evasion techniques let operators validate detection gaps that commodity toolkits can't expose.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.
Penetration testers and red teamers who need to generate weaponized Excel files without touching a Windows machine will move faster with XlsGen; it generates BIFF8 files with 4.0 macros in pure code, eliminating the dependency on Microsoft Office entirely. The 44 GitHub stars reflect steady adoption among practitioners who've already ditched Excel-dependent macro generation workflows. Skip this if your team relies on social engineering payloads that need Office Open XML fidelity or modern macro obfuscation; XlsGen prioritizes delivery speed over evasion depth.
